Our store has an entire section dedicated to batteries. Unfortunately, it would take a whole lot more space to have every battery in the world. However, we do have watch(or button) batteries which also fit in car key remotes, rechargeable telephone batteries, standard every day batteries (AA, AAA, AAAA, C, D, 9V), and more obscure ones (CR2, CR123, N, A23, A27, hearing aid batteries), as well as rechargeable AA, AAA, C, D, and 9V all in stock.
Cell phone and laptop batteries can be ordered and are usually less than a week away. Every device takes a different battery, but we usually only need the model number of the device or battery to make an order.
