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:
music cards, calculators, electronic watches and clocks, toys, electronic gifts, medical equipment, LED flash, card reader, small appliances, alarm system, , electronic dictionary , digital electronics, IT,etc.
