Battery holder

A battery holder is a little case where you can put batteries so they don't roll away or get lost. It's like a special home for your batteries! The battery holder has little metal parts on the inside that connect to the ends of the batteries to make them work. Sometimes the battery holder also has a cover you can put on to keep the batteries safe and snug inside. Imagine if you had a little house just for your toys or books, that's kind of like what a battery holder is for batteries!
