What you need to know about disposable batteries

Keep your batteries sealed in their original packaging. This helps protect them from the elements such as humidity. This also helps keep batteries from contacting each other or other metal objects. If this happens, the batteries could short-circuit and lose power. Keep your new and used batteries separate.

11.5: Batteries

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.
