Button Cell Batteries
A button cell is a single-cell battery that fits into small devices with its flat, coin-shaped metal housing. It is used in low-current applications such as wristwatches, car keys, calculators, kitchen scales, digital thermometers, and the clock and memory backup on a computer motherboard. This category lists Varta-branded 3 V lithium button cells such as the CR2032, CR2025, CR2016, CR2450 and CR1220, the 1.55 V silver oxide V76PX watch battery, and the 1.5 V alkaline V12GA (LR43) and V10GA (LR54) batteries. Choose the battery code according to the code on the old battery or in the device manual, the chemistry and rated voltage according to the type the device requires, and the diameter and thickness according to the battery compartment. In a CR code, the first two digits give the diameter in millimeters and the last two digits give the thickness in tenths of a millimeter: the CR2032 is 20 mm in diameter and 3.2 mm thick. The CR2032, CR2025 and CR2016, which have the same 20 mm diameter and 3 V voltage, should not be confused with each other; because their thicknesses and capacities differ, they may not seat in the compartment or may not make contact.
