Venom’s range of AA and AAA rechargeable battery packs continue that trend and now you can enjoy uninterrupted power not only for your video game controllers, but also your electronic toys, remote controls, cameras and other battery powered household items. Designed to retain charge when not in use, Venom batteries remove the fear of having zero power when you come to use your device after a period of no use. The batteries are compatible with all universal plug in AA/AAA wall chargers as well as the official made for Venom 4-Capacity and 8-Capacity Charging Docks (sold separately). The batteries will also charge when in a product via an appropriate charging dock, for example a wireless home telephone and dock.
