Measuring Voltage On A Cr 2025 Battery. The only way to reliably check/test a cell, is with some kind of a load. Have you ever wondered whether there was a quick and easy way to tell whether a coin cell battery is nearing the end of its life or still good.
It stopped giving light, so i removed the batteries and measured voltage. The average voltage output of the cr2025 battery, typically around 3 volts.
