These days, modern video and photographic equipment runs on batteries. They can be built-in and developed by the manufacturer for each specific model, or standard types AA and AAA. As a rule, built-in batteries are included, but they have minimal power and their charge does not last long, which means you always need to have a spare set. Many users are already abandoning disposable batteries in favor of rechargeable batteries of the same type. Yes, batteries are more expensive, but they can withstand more than one hundred recharge cycles, which means that in the end it turns out cheaper. We offer you an overview of the main types of batteries and their basic characteristics.
Simple and affordable way battery selection for photographic equipment, look in the instructions for your camera or video camera, where the manufacturer always gives clear recommendations on this issue. Only “original” batteries are too expensive or you have to wait a long time for the delivery of the corresponding model. At the same time, the photographic equipment market is represented by wide range analogues from other manufacturers, but they may differ in capacity and price, but they successfully cope with their main purpose - powering the device. So what do you need to pay attention to? buying batteries for cameras and camcorders ?
AA batteries
The AA battery type (rarely AAA) is usually installed on inexpensive cameras, less often on SLR cameras. But in professional models they are used only together with a booster - electronic device, increasing voltage and stabilizing the energy supply. Various models AA batteries differ in maximum capacity and output voltage. The capacity is determined by the number of on-off cycles; it is at this moment that more energy is consumed, and therefore the number of pictures that you can take with a given set of batteries is regulated. Batteries with capacities ranging from 1500-3200 mAh or more are now available for sale.
And the output voltage is a characteristic that affects the switching on of the device itself. When this indicator is very low, electronic system The camera will consider that the battery is low and therefore needs to be replaced.
Special batteries
If you use professional photo and video equipment, then the capacity of AA batteries will not be enough for you; it is better to use batteries that have a larger capacity and power. Typically, a battery of one model may be suitable for several models of cameras, so it is better to study the labeling of the device itself or the instructions for the photographic equipment. More often, the manufacturer offers several types of batteries that have the same shape and size, but different capacities (mAh, mAh). Original batteries are more expensive than their counterparts made in China, but they are more reliable and can withstand longer charge-discharge cycles.
Chemical composition
The cheapest are alkaline batteries: nickel-metal hydride and nickel-cadmium. Their main drawback is the presence of a memory effect, which is why the battery must first be completely discharged and then charged; Constant recharging gradually reduces the capacity of this type of battery. And the operating range of such batteries varies from -10 to +40 degrees Celsius. Lead-acid batteries are slightly more expensive and more reliable, but when completely discharged they fail.
Lithium-ion and lithium-polymer batteries, on the contrary, must be charged when the remaining capacity reaches at least 5-10%; or their capacity will decrease by 20% or more. But they are able to work in different temperature conditions, are durable, unlike salt and alkaline ones, which affects their price, and they are only compatible with a certain model of video and photographic equipment. They also have another advantage - they maintain the required voltage level during operation and do not self-discharge.
Battery charger
Depending on the type of battery, select charger. Typically, rechargeable batteries for photographic equipment come with a charger. If you want to purchase additionally, you should study the instructions for the equipment or read the battery manufacturer's recommendations. For AA batteries (rechargeable), the choice of charger is made taking into account their size, and chemical composition. For example, for alkaline batteries, chargers with a full discharge function are used, and the corresponding types of equipment for lithium-ion and lithium-polymer are used. Remember that models that have a fast charging function ultimately reduce the life of the batteries, and vice versa, slower charging gives the maximum effect in using batteries for a long time.
The variety of power sources for cameras can be divided into two types: disposable batteries (batteries) and rechargeable sources (batteries).
Each type includes different types batteries that have both advantages and disadvantages. Therefore, when we choose batteries for a camera, questions often arise: what is better and more practical: a battery or an accumulator? Which batteries are better? How many times can they be recharged? To answer them, it is necessary to systematize the available data.
Features of power supplies
To operate a modern digital camera, you need electricity, the source of which is batteries - rechargeable batteries or batteries inserted into a special compartment. Camera batteries are sold already charged, ready for use. Energy is produced through chemical reactions taking place inside the source body. In this case, the properties of chemical reagents change irreversibly. Therefore, after the energy is used up, the elements are discarded.
Chemicals inside the batteries also react to produce electricity. However, after discharge when connecting a constant electric current After charging, the chemicals are restored and the camera battery is ready for use again. Such charge/discharge cycles can be up to 1000 or more without loss of capacity.
Batteries for cameras can also be divided by form factor. AA batteries have always been the most common. It is quite logical that when, as a result of miniaturization, digital cameras became compact, they began to use AA batteries and rechargeable batteries of the same type to power them. However, for high-end cameras with high energy consumption, a AA battery was not suitable. A larger power supply capacity was required.
There were two solutions: either increase the number of batteries, or make powerful batteries for a specific camera model. And of course, we shouldn’t forget about marketing: the idea of tying a buyer to a battery from a particular company is so obvious that it was impossible to ignore it.
As a result, a situation has arisen where there are two types of batteries according to their form factor: AA batteries (rarely AAA) and... the rest - with a wide variety of shapes and sizes of batteries. Is it convenient for the consumer? The question is controversial. However, there is no shortage of batteries on the market, so there are no problems purchasing the right model.
Disposable batteries
An obvious advantage of disposable sources is their readiness for immediate use. The battery-powered camera does not need to be recharged. Sometimes this makes a difference.
However, as already noted, AA batteries have one serious drawback, which makes you wonder whether it is worth buying batteries of this type.
This disadvantage is the small capacity. Because of this, only digital cameras can work with disposable elements entry level, do not consume a lot of energy.
Serious cameras are equipped with powerful rechargeable batteries, their dimensions significantly exceeding the size of a AA battery for a camera.
There are several types of disposable batteries. They all have certain advantages and disadvantages. Let's look at which batteries cameras can work quite well with, and which batteries it is better not to use for cameras at all.
Salt batteries
Due to their low cost, they are still the most common type of disposable batteries. The reason for the low cost is the availability of the raw materials necessary for their production and the simplicity of the manufacturing technology.
The main disadvantages are typical for most types of AA batteries:
- During operation, a sharp decrease in the output electrical voltage may occur;
- Low electrical capacity;
- Sensitivity to low temperatures;
- High self-discharge rate (up to 30-40% per year of the original capacity).
Alkaline batteries
Perhaps the most popular type of disposable batteries.
They have a number of undeniable advantages over salt batteries:
- They have 1.5 – 2 times more capacity;
- Capable of delivering a discharge more evenly (no voltage drop during discharge);
- Self-discharge over a year of storage is no more than 10% of the original capacity;
- Less sensitive to low temperatures.
However, alkaline batteries are also not without their disadvantages:
- Quite a high cost (4-5 times higher than saline ones)
- Rapid loss of capacity when used in electrical appliances that require short-term significant current levels.
Despite their superior performance compared to salt batteries, alkaline batteries do not have all the necessary characteristics, necessary for full use in professional and. But for use in cameras of a lower class, they can be fully recommended.
Lithium batteries
The best of all disposable batteries.
Despite the rather complex design, more and more manufacturers are switching to their production, since this type of element has high performance characteristics:
- Capacity 2 times greater than that of alkaline ones,
- Uniform voltage output throughout the entire operating period, regardless of the load current
- Long (12-15 years) shelf life without loss of charge:
- Can operate at ambient temperatures from – 40°C to + 50°C;
- Light weight.
The main drawback is the price. Lithium batteries cost approximately 5 times more than alkaline batteries. And although their characteristics are well suited for digital cameras, using them as the main power source is very unprofitable economically. But as an alternative to batteries in the absence of an energy source to recharge the batteries, they are ideal. If, of course, the camera allows for the use of AA type elements.
Batteries
The vast majority of photographic equipment manufacturers have taken the path of using rechargeable batteries in their cameras rather than disposable batteries.
Firstly, the use of disposable batteries imposes certain restrictions on the power consumption of cameras, forcing it to be calculated based on the capabilities of the batteries, and not vice versa.
Secondly, until cheap types of AA batteries with the required energy characteristics have been created, the production of cameras for disposable batteries will be a bad solution. The consumer should not be allowed to spend more on batteries than the camera costs.
What types of camera batteries are there? AA batteries are widely used in compact digital cameras and ultrasonic cameras. Due to their limited size, soap dishes sometimes use AAA batteries. The rest of the cameras are mainly equipped with individually sized batteries.
Therefore, types of rechargeable batteries will be identified and considered based on the technologies and materials used in their production.
Nickel-cadmium batteries (NiCd)
Used since the mid-20th century. They began to be used in photography as flash batteries. Due to their reliability and proven manufacturing technology, they are still quite common in photographic equipment.
Main advantages:
- Can operate in a wide range of ambient temperatures;
- Capable of generating large currents, which is important in some modes;
- Withstand a large number (more than 1000) charge-discharge cycles without significant loss of capacity;
- Possess long term storage without loss of performance;
- Low price.
Flaws:
- Presence of memory effect. In this regard, it is necessary to periodically completely discharge the battery with subsequent mandatory charging;
- High self-discharge (up to 10% in the first day)
- Relatively large sizes other types of batteries;
- Difficulties with disposal due to the presence of hazardous chemicals.
The share of NiCd batteries is gradually decreasing.
Nickel metal hydride (NiMH) batteries
When NiMH batteries appeared (in the 80s of the 20th century), they were positioned as a replacement for nickel-cadmium batteries. However, the first models were inferior to their predecessors in many respects. Only a few years ago there was some progress in overcoming the shortcomings of the technology and they began to be used as batteries for cameras.
Advantages of batteries of this type:
- They have a 30% higher capacity compared to NiCd batteries;
- There is virtually no memory effect (without a long break in operation);
- They have less toxicity.
There are disadvantages and, unfortunately, quite serious ones:
- The number of charge/discharge operating cycles is almost 2 times smaller compared to nickel-cadmium batteries;
- 1.5 - 2 times higher self-discharge;
- High price.
The developers claim that this technology has great potential for improvement, and models with significantly higher performance are expected to appear in the near future.
Lithium-ion batteries (Li-ion)
With the advent of lithium-ion batteries in the early 90s of the last century, photographic equipment manufacturers received power sources that satisfy almost all needs when operating cameras. The best rechargeable batteries are produced using this technology.
The advantages include:
- High capacity, approximately 2 times the capacity of NiCd batteries;
- Ability to produce high voltage values;
- Compactness;
- Low self-discharge values (approximately 2-5% per month);
- Wide range of operating temperatures (from -20 to + 50 °C);
- Quite a large number of charge/discharge operating cycles (600-900);
- Low maintenance requirements.
The disadvantages include:
- Susceptibility to aging (failure of unused batteries that have been in storage for several years);
- Failure due to deep discharge;
- High price;
- Explosion hazard of some models.
Useful advice! Do not buy a lithium battery in reserve if you do not intend to use it at least from time to time.
A further development of lithium-ion batteries was the emergence of lithium-polymer batteries (Li-Pol). Having inherited high capacity and stability of the output voltage, they are significantly smaller in size and allow you to give them various shapes no loss of capacity. This opens up prospects for photographic equipment manufacturers to produce more compact models.
When choosing batteries for your camera, you must, first of all, strictly follow the recommendations of the photographic equipment manufacturer as set out in the operating instructions. For example, the instructions dictate that only the battery from this company is used for the camera. This is especially true during the warranty period. Failure of photographic equipment that did not use original batteries may be considered a non-warranty event with unpleasant consequences for the owner.
If the design of the camera allows the use of disposable AA cells, you should opt for lithium batteries famous brands. They are expensive, but they are the best batteries on the market. Firstly, they will allow you to take many more photographs than alkaline elements (not to mention saline ones).
Secondly, when operating in the camera, power supplies are subject to maximum load and become very hot. Batteries produced by unknown companies in a semi-handicraft manner may become unusable or even ignite. Naturally, the batteries should not be damaged.
If you nevertheless decide to purchase a non-original power source for the camera, then you must follow several rules:
- Buy a model from reliable manufacturers (list below). Purchasing a cheap product from an unknown company can result in a major nuisance;
- The batteries purchased must be manufactured using the same technology as the original ones. For example, a lithium-ion battery cannot be replaced with a nickel-cadmium battery of the same capacity and giving the same output voltage. The latter cannot provide a short-term supply of large current, and the camera may become unusable;
- It is necessary to purchase chargers for specific battery models. The latest generation of power sources are very sensitive to compliance with charging/discharging modes. The use of third-party chargers greatly shortens the life of the batteries and reduces their capacity.
The best battery manufacturers
The best battery manufacturers today are the following companies:
- Duracell, Energizer (USA);
- Varta (Germany);
- Panasonic, Sony (Japan);
- GP (Hong Kong).
These companies offer a full range of high quality disposable cells and batteries.
Among domestic manufacturers, we can note the high-quality products of the Cosmos company. Specializes in the production of alkaline disposable batteries of AAA and AA types.
The company's nickel-metal hydride rechargeable batteries are also well known to consumers.
Useful advice! If you have to shoot for an extended period of time in high temperatures and/or hot climates, always keep a spare set of batteries for your camera with you.
Every photographer knows firsthand how much his work depends on batteries and accumulators. No batteries - no pictures. When going to shoot another photo shoot, every photographer is obliged to provide himself with high-quality batteries. And how to make sure that they don’t let you down, we’ll talk in this article.
How familiar is the situation when, at the very important point The flash that is so necessary right now does not work. This is the result of inefficient batteries that you charged just last week.
The solution to this problem is, in fact, quite simple. You need LSD type batteries. This abbreviation is familiar to many, but in this area it has a different meaning and is translated as “low self-discharge”. As can be judged from the name itself, the operating time of such batteries significantly exceeds the operating time of conventional ones. Another plus is that they are compatible with most devices, cameras, flashes, strobe lamps and others.
Many of today's photo devices only run on built-in batteries, so you don't have much choice. But if your camera still runs on AA batteries, then you need to do right choice from all their diversity. NiMh or Nickel Metal Hydride batteries will likely be your best option. Before using them, it is better to read the instructions for your device and find out whether it supports this type of battery. Several sets of these batteries will allow your device to last as long as possible.
NiMh, Li and Zn batteries
The modern market for batteries and accumulators is quite diverse, so before purchasing, you better study the main types in order to know where to choose.
There are many lithium and nickel batteries sold in stores. They have both their pros and cons. Moreover, the number of minuses often outweighs. You can talk for a long time about the intricacies and reasons for choosing this or that type of battery, but it will suffice to say, based on experience, that for a photographer, either nickel-metal hydride or NiMh batteries will be the best. As mentioned above, in addition to a longer service life, these devices are used not only in cameras, but also in all kinds of auxiliary devices.
We must not forget the benefits of using certain batteries. For example, using NiMh batteries in LED lights, flashes and even radio triggers, the batteries will last slightly less than others, but in the end they will cost you less. It’s good to have several charged sets of four with you, then you don’t have to worry about any device malfunctioning.
More about NiMh batteries
If you have chosen NiMh batteries, then it’s time to find out that they are not the same. It just so happens that not all manufacturers provide the buyer with comprehensive information about their product, limiting themselves to a couple of phrases like “ready to use.” However, in reality there are several types of NiMh batteries. The first of them are ordinary NiMh, they consume charge even when the device is at rest. On the first day, about 23-24% of the charge is consumed, and another 1% on each subsequent day. Having carried out simple calculations, we see that more than half of the charge is consumed per month just like that.
The second type of battery is LD-NiMh. As mentioned above, this abbreviation stands for “low self-discharge”. If you do not use such devices, they will retain their charge at 85% for a year. That is, by charging such batteries and putting them in your bag, after any time during the photo shoot you can safely use them and not be afraid that they will run out at the wrong moment.
Thus, the difference is obvious: regular NiMhs will have to be recharged before each shoot, LD-NiMhs can remain charged for a whole year.
Are LD batteries suitable for me?
Perhaps, in terms of environmental friendliness and efficiency, you won’t find best option than NiMh. When using, the main thing is to remember to recharge them on time. But after trying LD-NiMh, you begin to feel significant differences between them.
The fact is that the capacity of conventional batteries is larger, on average 2700 mAh, for LD-NiMh batteries the capacity is 2100 mAh. It may seem that replacing batteries with a larger capacity with a smaller one is not profitable. But in practice, you will see that this is not what you need to worry about.
The solution to this issue is simple: if you choose a smaller capacity, then you can assume that you will have more spare charged sets, that’s what you need to take care of.
If you don't feel the need for more capacity, and don't forget to charge your batteries on time, then the LD-NiMh is exactly what you need.
Eneloop XX batteries from Sanyo
This product has been on the market since 2005 and can rightfully be called legendary. They are based on technology that dictates market development in this area.
AA and nickel-metal hydride batteries released by Sanyo can retain their charge for 5 years. New Eneloop batteries are designed to operate for 1800 charge and discharge cycles. The previous generation lasted 1,500 cycles, which is 20% less than the new product.
Perhaps these batteries are one of the best on the market at the moment. The problem is that they are not so easy to find everywhere. However, other companies are actively improving LD-NiMh battery technology. Products from Energizer, Duracell or Ansmann are available in abundance. For example, you can find batteries with an increased capacity of 2500 mAh, which, accordingly, increases their operating time.
Panasonic batteries
Another option that is fairly easy to find on the market is Panasonic batteries. They can withstand up to 1600 charge and discharge cycles, which is 600 more than previous models. In addition, it is no secret that Panasonic bought the Sanyo brand, so it is natural that their technologies will be mixed and in the near future, the consumer will not feel any special differences between the two types of batteries.
In conclusion, I would like to give a few more tips. If you decide to use rechargeable batteries, make sure they are purchased from a reputable store. Do not waste time on charging; fast charging can only be used when there is an extreme lack of time. The indicated number of charge and discharge cycles will only be valid if charged correctly. And yet, there is no need to mix and use old and new batteries at the same time. It is best to use specific markings so as not to confuse fresh batteries with used ones.
Based on materials from the site:
Surely many of you use cameras that are powered by ordinary AA batteries. A camera is a device with a fairly large energy consumption, so even the best batteries last for 300-400 frames, after which you have to buy new ones and then even new ones - the process is endless and quite a lot of money is spent on batteries. This problem can be solved by purchasing batteries once.
Why is it beneficial to use rechargeable batteries instead of regular batteries? Batteries can be used repeatedly - after the battery is discharged, you charge it and again get a battery ready for use. Modern AA batteries can be charged up to 3000 times – i.e. By purchasing batteries once, you avoid purchasing 3,000 ordinary batteries in the future. The savings are obvious.
But which batteries are best to choose for your camera? After all, now many manufacturers produce AA batteries of various capacities. Let's try to understand this issue.
First, and the most important criterion for choosing batteries for a camera is current output. Many may disagree and say that the main thing is the capacity, and the higher it is, the more frames can be taken with one charge. This statement is wrong. The large capacity of a finger-type battery is not always capable of providing the maximum number of frames from a single charge. Why is this so? Because absolutely all digital cameras have a power controller that controls the voltage on the batteries. It is the power controller that signals when the battery is low. The controller determines the level of battery discharge by the voltage on the element itself - in other words, it measures the voltage and if it is below the nominal voltage (the so-called lower voltage limit) - it sends a signal about the need to replace the battery. So, batteries with high current output are capable of delivering their entire capacity to power the camera without reaching the lower voltage limit. For example, if the battery has a capacity of 2000 mAh, all of these 2000 mAh will be used to power the camera. What happens to batteries with low current output? In such batteries, as the battery discharges, the voltage drops and the lower limit of the voltage drop is reached much earlier than the battery is discharged. There is energy left in the battery, but the camera will not be able to use it, because... The power controller will report low voltage. Thus, in batteries with a capacity of 2700 mAh and low current output, the working capacity will be 1700-1800 mAh, and the camera simply cannot “get” the remaining capacity from such batteries. This is easy to check - such batteries can be taken out of the camera (which asked to replace the battery) and inserted into a regular flashlight - they will work for a very long time thanks to the residual charge.
Often, with high-current batteries with a capacity of 2000 mAh, it is possible to take more shots than with ordinary batteries with a capacity of 2700 mAh.
The second criterion for choosing batteries for a camera is capacity. The large battery capacity combined with high current output will give you the maximum number of shots from a single charge.
The third parameter when choosing batteries for photographic equipment is self-discharge . First, let's understand what this self-discharge is. Absolutely all batteries lose their charge when stored (even if you don’t use them). The loss of charge during storage is called self-discharge. Self-discharge is present in all batteries, only in some it is less pronounced, in others it is more pronounced. Low self-discharge batteries can retain up to 85% charge after 5 years of storage. Using such batteries is very convenient - after charging, you can insert them into the camera at any time, start shooting and get the maximum number of frames. What happens when using non-low self-discharge batteries? Such batteries often lose up to 50% of their charge after several months of storage. Such batteries will have to be recharged before each use, which is not always convenient and there is not always time for this.
Today, the best batteries for any photographic equipment are Japanese batteries from the Eneloop series.
It is Eneloop batteries that combine all 3 parameters - high current output, low self-discharge and high capacity.
Eneloop batteries are available in 3 types:
- Panasonic Eneloop Pro 2550 mAh () – for professional photographic equipment;
- Panasonic Eneloop 2000 mAh( ) - for amateur photographers;
- Panasonic Eneloop Lite 1000 mAh( ) – for devices with low energy consumption.
For photographic equipment, it is recommended to use the first two types - Panasonic Eneloop Pro 2550 mAh(BK-3HCCE) and Panasonic Eneloop 2000 mAh (BK-3MCCE). These batteries are capable of providing the maximum number of frames from a single charge.
I hope this article will help you make the right choice and not miss a good shot due to a dead camera battery.

Hello, dear readers of my blog. I’m in touch with you, Timur Mustaev. I bought myself a new set of batteries for the flash. It took me a long time to choose, but I still made, in my opinion, the right choice. So which ones I purchased exactly, you will find out if you read the article.
And so, as you already understood, today we will talk about rechargeable batteries. In this article I will tell you in detail about how you need to choose batteries for your devices. After reading this article, you will know everything about batteries in general and what types of batteries are needed specifically for your device.
You will also find answers to the questions: Why do batteries discharge in the cold? Why aren't the batteries charging? Which rechargeable batteries are better? Well, let's get started?
Today, the number of devices that operate using batteries is very large, and it is constantly growing. But buying them every time is too expensive and not at all profitable. Then there is a need to purchase rechargeable batteries (AB) that can be recharged several times. Their cost is higher than that of conventional batteries, but in the long run they are still more profitable to use.
There are several of the most common AB sizes, these are AAA and AA. People call AAA size pinky, and AA finger size. They received their popular names due to their external resemblance to the fingers of a human hand. AA is like the index finger and AAA is like the little finger.
Battery types
There are several types of batteries depending on the materials from which they are made, capacity and voltage. The most common:
- Nickel-cadmium. Designated and labeled as Ni-Cd;
- Nickel metal hydride. Designated and labeled as Ni-Mh;
- Lithium-ion. Designated and labeled as LilON;
- Lithium polymer. Designated and labeled as LiPol.
Mostly, replaceable external power supplies are used for cameras, radio phones, toys, flashes, flashlights, MP3 players and so on. So how do you choose the right batteries for your device? It's not at all as difficult as it seems.
Pros and cons of AB
So, let's now take a closer look at the advantages and disadvantages of existing types of AB.
- Have the ability to work in different temperature environments;
- Sold at relatively low prices;
- They are light in weight.
- Discharge quickly;
- Capable of charging only when completely discharged;
- Discharges even when not in use.
- Able to retain charge for a long time;
- Have the ability to produce high voltage;
- Long-term use.
- They have quite a lot of weight;
- Discharge quickly when temperature changes environment;
- Sold at a relatively high price.
LilON And LiPol have common pros and cons:
- Have long-term charge retention;
- They have very little weight;
- Retains charge for a long time.
- Rarely found in battery form;
- Can't stand it large quantity recharges;
- Very expensive.
Choice
If you need to purchase AB, then it is best to take the device for which you are purchasing them with you to the store so that the consultant can help you find required product. Sellers are also often confused when selecting batteries, even if you told him the exact model of your device and all the necessary parameters. Each device requires a different voltage and battery size.
When choosing, you should pay attention to many factors. The main one is the ambient temperature. If you are going to use the device at high or low temperatures, you should purchase Nickel-Cadmium batteries. If it is not important to you in what temperature environment your device will be used, then you should purchase batteries marked Ni-Mh.
The second factor you should pay attention to when choosing batteries is their operating time. If you need the device to function for a long time, then it is worth purchasing Nickel - Metal Hydride. They will help maintain charge for a long period. Best suited for flash photography.
The third factor is the applied voltage. There are no clear recommendations regarding the type of batteries. The only thing you need to pay attention to is the requirements of the device. They are usually indicated in the instruction manual. You should not purchase batteries without knowing what voltage you require. But basically, the voltage in them is the same 1.2 - 1.5 Volts.
The fourth is, of course, the type of device for which the batteries are actually purchased. For a mobile or radio phone, you should purchase batteries labeled LilON, as they are available in specialized forms other than finger and little finger batteries.
Fifth, and very important parameter, which also needs to be paid attention to, is the volume of the battery, and it is indicated in mAh - miles ampere hours. And the larger the battery capacity, the longer the device will work, but at the same time it will take longer to charge.
After you have purchased the batteries you need, you should pay attention to the fact that they require a specialized charging apparatus. Sometimes it is sold complete with batteries, but sometimes it has to be selected separately.
If you purchased Nickel-Cadmium batteries, then you should buy a charger that will provide a full discharge function, since it is impossible to charge undischarged batteries of this type.
If you purchased Nickel - Metal Hydride, then you should pay attention to their brand. It is worth buying a charger for batteries of this type exclusively from the same manufacturer.
If you bought Lithium-Ion or Lithium-Polymer, then you should purchase a universal type charger so as not to make a mistake in choosing the right voltage and connector, since such batteries have different shapes and capacities.
Conclusion
So, friends, I hope that this article helped you decide on the choice of battery for your devices, or at least helped you learn more about batteries in general. Now you can safely go to any store that specializes in selling equipment and buy the batteries you need. In general, it’s much easier to buy, for example, in Technosila or Eldorado.
But do not forget that sometimes it is better to buy several sets at once. This will help you always have working device. While one set of batteries will power the device, the second will be charging.
With this, I say goodbye to you and wish you successful shopping. I think that now you will definitely not regret the purchase, and will make the most correct choice.
No, no, I didn’t forget and promised to tell you what batteries I purchased. And so, this is Panasonic Ni-Mh, with a capacity of 2700 mAh. I am very pleased with the purchase, and now my flash will work even better.
Advice. Don't pay much attention to the brand, it won't do much. Choose one with the maximum mAh volume, and preferably Ni-Mh.
If this article helped you, may it help others too! Share it on social networks and you will be happy.
Still, which brand do you trust?
All the best to you, Timur Mustaev.
