Battery Mart sells high-quality rechargeable batteries in all the common household sizes, including AA, AAA, and 9 volt. These batteries are used in TV remote controls, flashlights, smoke detectors, games, and more.
There are three chemistries these rechargeable battery packs are made of: NiCd (Nickel Cadmium), NiMH (Nickel Metal Hydride), and Li-Ion (Lithium Ion). Li-Ion batteries provide the most power and runtime. NiMH rechargeable batteries strike a good balance between price and performance. NiCd batteries are inexpensive and will charge quickly.
