Panasonic eneloop pro BK-3HCDE/2BE is a two-pack of rechargeable AA batteries for devices that use standard AA cells. The exact model is listed as a pack of two in Panasonic’s eneloop catalogue.
Each cell has a minimum capacity of 2500 mAh. The eneloop pro range is designed for higher-drain equipment, including camera flashes, wireless keyboards and mice, game controllers and radio-controlled cars. That makes these cells a rechargeable option for frequently used devices with relatively high power demands.
Panasonic states that eneloop pro batteries can be charged up to 500 times under its specified test method. Actual results depend on use conditions. The pack contains two AA batteries.
