The A23 battery is a common battery. It has high indicators of energy capacity, voltage. It is mainly used to power small-sized RF devices.
You can meet it in most small key fobs from car alarms, proximity keys, and other miniature gadgets.

Specifications A23
A galvanic cell is a chemical source for generating electric current. In a situation with A23, this alkaline battery. Visually it looks like a standard AAAbut a little smaller. The shape is cylindrical, elongated.
The sizes are as follows:
- diameter - 10.3 millimeters.
- length - 28.9 mm.
If you take apart the A23 battery, you can see what it consists of. These are eight identical alkaline elements LR932, in appearance resembling a tablet.
The electromotive force of the battery is 12 volts. In this case, a typical capacity of 40 mA per hour. Weight is about 8 grams (may vary by different manufacturers). Designation according to IEC 3LR50 (alkaline type). Power device contacts with a positive end with a protrusion, with a minus a flat end.

Battery Applications
The scope is miniature radio frequency devices. In other areas, they can be met extremely rarely. The main options where batteries are used are radio alarms, radio remote controls, as well as wireless call buttons.
The increased voltage that the power supply in question possesses is necessary for high-frequency transmitting and receiving devices.
Important! Using options with not such a high voltage can not provide the necessary power, even if the radio device will work, then a short time.
Battery analogs A23
Battery analogs A23 do not always include a digital combination in their designation.
Usually, as a replacement, choose:
- 8LR932
- 8LR23
- ANSI-1181A
- LRV08
- K23A
- Mn21
- E23a
- GP23A
- V23GA
All of them are similar in energy intensity and service life.
When choosing, attention should be paid to the main parameters. Batteries with such a chemical component usually have limitations on the possible range of temperatures used. For example, if the battery will be used in northern latitudes, then the limitation on minus temperatures should be maximum.
Can I charge the A23 battery
The A23 battery is not a battery and it is impossible to charge them, this is determined by the production features and the materials used. The self-discharge coefficient of the power source is considerable. In addition, the battery has a low cost.
The ratio of these qualities makes the fact that it cannot be charged, like a regular battery, not so significant.
Popular manufacturers and their features
The variation in the cost of batteries of this type is large. To say exactly which manufacturer is the best is not possible.
Some of them provide expensive batteries that will work perfectly for two or even three years with constant use. Others have a slightly shorter life, but they can cost several times less.
One of the best ratios in terms of price and quality for power supplies from GP and Duracell (name MN21) and Energizer. Such models have high energy intensity, good temperature performance, as well as a low coefficient of self-discharge.
However, not only these models deserve attention. Also pay attention to the options of manufacturers:
- Trophy
- Camelion
- Varta;
- Panasonic
- Focusray
- Camelion
- Videx
- Alkaline
What to look for when purchasing
The higher the specifications, the better. This is not to say that the higher the cost, the better the parameters. It often happens that popular brands present models on technical characteristics that are average, but at a high price.
When choosing, pay attention to:
- capacity;
- voltage;
- sizes
- Release date;
- shelf life;
- packaging quality;
- self-discharge coefficient (the smaller it is, the better).
There are a lot of batteries marked A23 on the modern market. Alkaline variants almost all have decent quality, not only produced abroad, but also domestic. The main thing when choosing and buying is to take into account the manufacturer’s guarantees, since during a factory defect it will then be possible to change the battery with them.
