The Panasonic Eneloop Pro (model BK-4HCDE) is a 5th generation NiMH rechargeable battery type AAA (R03) for professional use. It boasts an improved nominal capacity of 930 mAh (900 mAh minimum guaranteed) while maintaining low self-discharge (1 year → 85% charge retention) which is better than most alkaline single-use batteries. This new cell can operate at temperatures as low as -20°C.
Eneloop Pro rechargeable batteries are particularly well suited for use with photography equipment. Their large capacity and low internal resistance and patented construction allow them to power the equipment for a really long time.
After Panasonic acquired the assets of Sanyo Electric Co. Japan back in 2014, the Eneloop batteries now carry the Panasonic logo. This however is the only change: just like before, all new Eneloop cells are manufactured in Japan and are delivered pre-charged with clean solar energy, ready for use out of the pack.
