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.

Different battery types have different advantages and disadvantages. Ultimately, the type that is best for a particular use depends on a number of factors including cost, weight, size, and shelf life. The table below identifies batteries found in households and includes uses, sizes, and more information.

Each of the batteries listed below can be recycled. For more information on how and where, click here.
