Power various electronics, including digital cameras, gaming devices, and flashlights, with this pack of four eneloop pro AA Rechargeable NiMH Batteries from Panasonic. Each features 1.2V of output power, a 2550mAh capacity, and a 3.06Wh rating. The cells come pre-charged and ready to use, and are rechargeable up to 500 times. Additionally, as they are not subject to any memory effects, they can be charged when fully or partially drained and their full capacity will continue to be usable after each cycle. Thanks to their very low self-discharge rate, the batteries will retain up to 85% of their charge after 1 year in storage. Engineered for durability, the eneloop pros perform well in extreme temperatures as low as -4°F.
