The Panasonic Eneloop (model BK-4MCCE) is a new, 4th generation NiMH rechargeable battery type AAA (R03) with a nominal capacity of 800 mAh (750 mAh minimum guaranteed) and extremely low self-discharge (1 year → 90% charge retention; 5 years → 70% charge retention) which is better than most alkaline single-use batteries. This new cell comes with even longer life expectancy: up to 2100 charge/recharge cycles and can operate at temperatures as low as -20°C.
Eneloop rechargeable batteries are well suited for use with photography equipment: due to their big capacity and notable charge retention abilities they perform better than alkaline batteries in low-powered devices such as remote triggers and timers.
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.
