These batteries are commonly used in smoke detectors, remote controls, and various electronic devices. I appreciate how they provide a reliable power source while being environmentally friendly.

Capacity and Power Output

One of the key factors I consider is the battery’s capacity, typically measured in milliampere-hours (mAh). Higher capacity means longer usage time for my devices.
