1.5V AG4 LR626 SR626SW 377 LR66 177 Alkaline Batteries Button Coin Cells Watch battery digital calipers
Description:
Coin cell batteries are thin, circular batteries often used to power hearing aids, wristwatches, key fobs, digital calipers and test instruments, and small flashlights. Commonly called button batteries or watch batteries, they have a low self-discharge to hold their charge for a long shelf and service life. These batteries can be discarded when their charge runs out.
Applications:
calculators, clocks, watches, computers, camcorders, remote controls, electronic instruments, digital voice recorders, blood glucose meters, cholesterol testing meters, LED lights and others
