A battery holder is one or more compartments or chambers for holding a battery or batteries. In the case of dry cells the holder is also usually responsible for making electrical contact. In the case of wet cells normally cables make electrical connection to posts or terminals as commonly found on automobiles, emergency lighting, backup batteries. Battery holders developed in parallel with batteries over time and as battery package sizes shrunk so did the holders. Todayís battery holders are either a metal or plastic case with a shape molded in to accept batteries or a plastic holder with contacts.
