How AG10 Batteries Work

AG10 batteries create electricity through a chemical reaction inside the small button-shaped cell. When you put the battery in a device, the reaction between the zinc case and manganese dioxide produces a tiny electric current. This current powers your device, keeping it running smoothly.

Over time, the chemicals inside the battery get used up, and the battery loses power. That’s when it’s time to replace it. AG10 batteries cannot be recharged, so once they run out, you need to dispose of them properly.
