Batteries are broadly classified into primary and secondary categories. Primary batteries are for one-time use whereas secondary batteries are rechargeable.Both types of batteries are further classified depending on the chemicals they contain. The result – sometimes confusing – is that batteries come in various chemistries, types, and sizes to fit different uses.
