The Panasonic Eneloop (model BK-3MCCE) is a new, 4th generation NiMH rechargeable battery type AA (R6) with a nominal capacity of 2000 mAh (1900 mAh minimum guaranteed) and extremely low self-discharge (1 year → 90% charge retention; 10 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 very well suited for use with photography equipment and flashes in particular. Their unmatched low internal resistance and patented construction allow them to yield tremendous amounts of power in a short period of time — which is exactly what your flash wants while it recharges its capacitor.
The double package allows you to equip your flash with a primary and a spare set of batteries at a lower price.
