Coin Battery Basics

Some coin cells list the size in their name like below:
2016 battery is 20mm diameter x 1.6mm height.
2032 battery is 20mm diameter x 3.2mm height.

-These are both 3v rated, being the 2032 is double the height, it is approximately double the mAh capacity rating. 2016’s are generally stacked to produce a 6v rating used in a 2032 holder, otherwise a 2032 is generally preferred for 3v applications because of the larger capacity.

If you are looking for a coin cell battery but cannot locate it in our system, it is recommended to first filter out the voltage required and then by the physical size.
