Verbatim's Premium Rechargeable Batteries can be used in digital cameras, remote controls, and other devices. They are up to 5 times longer lasting than alkaline batteries in digital cameras. These batteries are pre-charged, can be used straight out of the pack and will retain their charge (up to 80%) for up to 1 year. Rechargeable batteries are environmentally friendly. Each NiMH battery equals 500-1000 alkaline batteries and recharging batteries means less waste.
