Which rechargeable batteries are better to choose in terms of price / quality ratio?
There are different types of batteries. Before buying a particular type, you should determine in what conditions you plan to use the battery.
The main parameter of batteries that affects the choice is capacity. It affects the amount of energy that a battery can store. The larger the capacity, the more the device will work.
It is important to consider here that each device has its own energy consumption, so the battery will show a different result on the watch and in the camera.
Capacity is affected by the size of the battery.
In addition, the choice of a battery is influenced by: the level of self-discharge, the number of potential recharge cycles, the operating time on a single charge, the charging speed, the temperature limit suitable for the battery during operation.
What to look for when choosing
Let’s figure out how to choose rechargeable batteries. In addition to the type of battery, when choosing, you also need to pay attention to other characteristics.
- Capacity. The larger it is, the longer the device can work on a single charge. However, the charging time will also increase.
- The number of recharge cycles. The larger it is, the more times you can recharge the battery and the longer it will last.
- Self-discharge. This characteristic indicates how quickly the battery is discharged during storage, that is, when it is not in use. Elements with low self-discharge are marked with the symbols LSD (low self-discharge).
- Issue date and expiration date. The best models retain their characteristics for ten years.
Important! Manufacturers are also important when choosing a battery. Notable companies: Duracell and Energizer. In addition to them, they have proven themselves well: Panasonic, Fujitsu, GP, Soshine, Xiaomi.

| Expert assessment: ⭐ 9.7 / ten | |
| Owner Review | |
| I use two controllers Xbox series. I can’t say for sure by the clock, but it lasts longer than from GP batteries. The only thing that I didn’t really like was that after the console reports that the batteries are low, there are enough minutes for 10 games.

Criterias of choice
All produced batteries are characterized by several standard parameters that determine the scope of application. Some of them are made in the image of disposable batteries and are designed to replace them. On the other hand, not all batteries can be found equivalent among batteries. The most common galvanic cells of standard sizes AA and AAA:
- AA or “finger” batteries are the most widely used. Their dimensions: length — 50.5 mm, diameter — 14.5 mm. By chemical composition, they are: saline, alkaline or lithium;
- AAA or “little fingers” batteries have the following geometric dimensions: length — 44.5 mm, diameter — 10.5 mm. They can be saline, alkaline or lithium;
In addition to the batteries of the form factors discussed above, galvanic cells are also produced in other sizes:
- BUT — now practically not used. Previously, they could be found in computers and non-standard devices. Their dimensions: diameter — 17 mm, height — 50 mm;
- AAAA — small batteries, most often alkaline. They are used in medical glucometers, photographic equipment. Dimensions: diameter — 8.3 mm height — 42.5 mm;
- AT — used in lighting fixtures. Geometric dimensions: diameter — 21.5 mm, length — 60 mm;
- FROM they are also called “medium”. Geometric dimensions: length — 50 mm, diameter — 26.2 mm;
- D — the first current sources of this form factor appeared in 1898. They are used in radios, clocks and tape recorders.
Technology. Many parameters depend on what physical processes underlie the generation of electric current: sensitivity to environmental conditions, charge speed, the presence of a “memory effect” and more. The memory effect is a feature in which batteries “remember” the mode of operation if they are not completely discharged before the next charge. This leads to a drop in capacity, since during subsequent cycles the battery will only give current up to the limit fixed by the chemical elements. To avoid the memory effect, fully discharge the battery before restoring it.
Nickel-cadmium. These rechargeable batteries appeared among the first and for a long time there was no alternative to them. Despite the appearance of other, more advanced systems, they retain their position in devices where reliable uninterrupted power is needed under high load.
Advantages
- Ability to work under high load
- High current charging in a short time is allowed
- Heat resistance — the batteries themselves almost do not warm up during charging due to low resistance
- Possibility of storage in a discharged state
- Resistance to low temperatures
Flaws
- Harmful impact on the environment
- Expensive safe disposal
- memory effect
- Impressive self-discharge when idle
- Inability to use in buffer mode
The displacement of nickel-cadmium batteries is observed in developed countries, where environmental standards are being tightened. In domestic use, nickel-cadmium batteries are most often used in photo and video equipment, as well as in radio-controlled models.
Nickel metal hydride. They arose as an attempt to get rid of two main negative parameters of nickel-cadmium batteries — the memory effect and the harmful effects on the environment. It was possible to achieve complete environmental safety of these batteries. They are practically not subject to the memory effect — they can be recharged in any state. A big plus is also an increase in capacity with similar parameters — by about 20%. However, it was not without its drawbacks: due to the nature of the technology, the service life of nickel-metal hydride batteries is lower than that of competitive options, their self-discharge is greater than that of competitors. If you need to store Ni-Mh batteries, then they need to be fully charged and sent to the refrigerator, preferably in a sealed zip bag against moisture.
Lithium-ion. This type of battery is extremely common in mobile phones, players, smart watches and other gadgets. However, the manufacturer often produces them in the form-actor of AA batteries.
Advantages
- Extremely low self-discharge current (an idle device retains a charge for months)
- Large capacity in a small size
- Ability to work with different currents
- The output voltage does not drop, but remains until the full discharge
Flaws
- This is the sensitivity to changes in currents, as well as to a full discharge. Therefore, this type works best in conjunction with electronic controllers and interlocks that equalize the input voltage, and also automatically turn off the battery when certain indicators are reached.
Lithium-ion batteries are “afraid” of the cold, actively losing their charge. They can also catch fire, so be careful with them.Form Factor It was the form factor that the batteries inherited from their predecessor batteries. Typification of the sizes and shapes of batteries allows you to comfortably replace them, achieving the optimal duration of work. There are other sizes of batteries, but they are less common. In order to get a battery of greater power, AA or AAA battery packs connected in series are used. In this case, the battery capacity remains equal to the capacity of one element in the circuit, and the output voltage remains the sum of single indicators. For example, a common battery format for toys and radio-controlled models is 4.8 V, that is, 4 “banks” of 1.2 V.
Capacity. The capacity parameter is equivalent to the time during which the device can be fully powered by the current emitted by the battery. In other words, the larger the capacity, the longer the device can work on a single charge. This parameter is measured in milliamp-hours. The range of commercially available values can vary from 100 to 12000 mAh. It would seem that choosing the most capacious battery is the best solution. But in practice, everything is not so simple. The larger the battery capacity, the longer it takes to charge. And it’s good if high voltage charging is available. But when it comes to metal hydride cells, which are recommended to be fed with a low current, the convenience of devices with a large capacity no longer seems so obvious. Proceed from the power consumption of the device and its mode of operation.
The number of recharge cycles. The number of charge / discharge cycles is comparable to the battery life. To attract buyers, sellers overestimate the rates, which actually turn out to be many times lower. By indicating on the packaging the possibility of up to 2000 reloads, the manufacturer means ideal conditions and strict adherence to operating rules. In practice, good batteries rarely last more than 500 charge cycles.
Self-discharge. By self-discharge is meant the residual energy in the battery for a certain time period. The parameter measured as a percentage is associated with:
- Chemical composition, technologies;
- operating conditions;
- charger specifications.
Nickel-cadmium batteries with LSD technology have proven themselves better than others in terms of self-discharge, which save from 80 to 99% of capacity after a month of storage. Although in advertising their products, many manufacturers give these figures for a one-year period.

Batteries
Modern batteries can be created using a variety of technologies. The capacity, voltage and many other parameters of the battery depend on this.
- The cheapest are salt batteries
- their invention happened in the middle of the 20th century. Such batteries are equipped with electrodes made of manganese and zinc oxide. Each electrode is placed inside an electrolyte formed from an ammonium chloride solution. The electrodes are connected to each other by a salt bridge. And if earlier such batteries “flowed” after a couple of months, now the shelf life has increased to at least two years. The capacity of such products has also slightly increased (this applies to products under famous brands). - Around the middle of the last century were invented and alkaline (alkaline) batteries
. Now they are the most common — this is facilitated by the cheapness of their manufacture, and a decent capacity, and a long shelf life. In the chemical system of such batteries, all the same electrodes made of manganese dioxide and zinc are used, but potassium hydroxide is already used as an electrolyte. On the case of such batteries there is an inscription “Alkaline” — this is how an alkaline battery can be distinguished from a salt one. - Separately, one could talk about mercury and silver batteries, but it is almost impossible to find them in retail. We can say that such batteries are experimental. They are extremely rare for sale due to the complexity of manufacturing and high cost. Yes, there are some problems with disposal.
- More and more popular now lithium batteries
. They include a lithium cathode and an anode made of different materials. Between the cathode and the anode are a separator and a diaphragm, which are impregnated with an organic electrolyte. In a word, the design turns out to be very complex, but it significantly increases the energy intensity of the battery. Also, a distinctive feature of a lithium battery is the independence of the capacity from the load current. The shelf life can reach 10–12 years. You can distinguish such a battery from an alkaline or salt battery by the inscription “Lithium”.

Tips
If you need to purchase batteries, 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 the right product. Sellers are also often confused when choosing batteries, even if you told him the exact model of your device and all the necessary parameters. Each instrument requires a different voltage and battery size.
- When choosing, you should pay attention to many factors. The main one is temperature environment. If you are going to use the device at high or low temperatures, then Nickel-Cadmium batteries should be purchased. If you don’t care what temperature environment your device will be used in, then you should purchase batteries marked Ni-Mh.
- The second factor that you should pay attention to when choosing batteries — duration their working hours. If you need the device to function for a long time, then you should purchase Nickel — Metal Hydride. They will help to keep the charge for a long period. Best suited for flash photography.
- The third factor is is the applied voltage. There are no clear recommendations about the type of batteries. The only thing you need to pay attention to is the requirements of the device. They are usually listed in the user manual. Do not buy batteries without knowing what voltage you need. But basically, the voltage in them is the same 1.2 — 1.5 Volts.
- The fourth is, of course, device type, for which the batteries are actually purchased. For a mobile or radio phone, you should purchase batteries with the LilON marking, as soon as they are available in specialized forms other than finger and little finger batteries.
The fifth, and very important parameter, which also needs to be paid attention to, is volume battery, and it is indicated in mAh — miles of ampere hours. And the more volume the battery holds, 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 what is needed for them. specialized charger. 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 full discharge functionas it is not possible to charge unused batteries of this type.
- If you purchased Nickel-Metal Hydride, then you should pay attention to their brand. Buying a charger for batteries of this type is exclusively from the same manufacturer.
- If you bought Lithium-Ion or Lithium-Polymer, then you should purchase a charger universal typeso as not to make a mistake with the choice of the desired voltage and connector, since such batteries have different shapes and capacities.

Which are better, which are worse, is there any point in overpaying
The key advantage of all lithium batteries
- stable voltage throughout the service life in a wide range of currents and temperatures. Those. with these batteries, both the flashlight and the motor will work for the entire battery life with the same efficiency. If neither is required, then neither, then there is no point in overpaying.
manganese dioxide.
The battery is cool as a backup since there is no passivation, but with a constant load there is not much point in them, unless you need exactly 3 volts in your electronics. There are manufacturers of smart home sensors who are very fond of cr123, their love is very ambiguous.
Alkaline and lithium iron dioxide.
As a matter of fact brothers, easily change one for another. In the remote control, mouse, keyboard, children’s toy without motors, our controllers and other low-power devices are ideal to use alkaline. Lithium iron dioxide, due to its constant voltage and stable capacity regardless of current, is ideal for: flashlights, motors, smart remotes, thermostats, i.e. those devices that consume significant currents or constantly control something or transmit data.
Lithium thionyl chloride.
They stand apart due to their voltage of 3.6 volts and the passivation effect. They are suitable for devices that can handle such voltage and that have a constant milliamp load or a periodic tens-hundred-milliamp load. Not suitable for devices that constantly consume microamps or that are not used for a long time, as they are back-passivated.
