Eneloop is a combination of a rechargeable and a disposable battery. Rechargeable batteries are normally supplied discharged because of a high rate of self discharge. Eneloop have a very low self discharge (85% charge after 12 months storage) so can be supplied charged and used right straight the purchase.
Can be used for high drain devices such as digital cameras, where alkaline batteries typically do not perform well, and also low drain appliances such as MP3 players and clocks.
This charger kit will charge the 4 included AA batteries in approximately 6 hours. In addition the charger can be used for regular NiMH batteries. AAA batteries (Eneloop and regular) can also be charged.
