For other uses, see Battery (disambiguation). An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.
Batteries require proper storage. Always store battery cells in a plastic case when you need to carry them around. Avoid contact with other metal items such as key, knife, metal pen, etc. Stop using a cell if the wrapping plastic tube is damaged, scratched or internal metal exposed.
