Voltage, capacity and dimensions - an eternal compromise

For every power source, the designer has to decide on a certain compromise. As capacity and nominal voltage of battery or accumulator increases, its dimensions inevitably grow - the limitation here is so called energy density which determines how much energy can be accumulated in given volume or unit mass of source. It means that - for example - capacity of small battery with voltage of 12V is very small, but much more energy can be provided by large cell with 8 times lower voltage. The capacity of a given energy source is described as the time during which a cell, battery or accumulator will be able to deliver a current of a specified amperage - this is where the unit of (m)Ah capacity, or (milli)ampere-hour, comes from.

Remote control batteries

In remote controls for unlocking the central locking system in the car and in some other remote controls, tiny batteries with a voltage of 12V are very often used. Their designation is sometimes written as 23A or A23, but there are also a number of other commercial names such as LR23A or V23. Batteries of this type have a diameter of 10 mm and are 28 mm long. Very similar, but slightly smaller, are 27A batteries - they also offer 12 V voltage and their dimensions are 7.7 mm x 28 mm. In our offer you can also find CR123A batteries with voltage of 3 V and dimensions of 16.8 x 34.5 mm. It is worth to know that four times lower (compared to A23 and 27A) nominal voltage and slightly larger dimensions result in significant increase of capacity of this type of batteries, up to 1400 mAh.

In our offer you will also find other types of batteries. Large zinc-carbon batteries (cells) marked R14 used to be very popular. Their large diameter (about 26 mm) and length (50 mm) meant that they were often used especially in flashlights. Even today, you can find on the market many devices that use these batteries - their high capacity allows you to enjoy the work of a flashlight or an electronic toy for a long time. In our offer you will find solid alkaline batteries LR14 made in Duralock technology and regular zinc-carbon batteries from Panasonic.
