The Eneloop Smart and Quick 1.5 Hour Charger with 4 AA Batteries is the ultimate kit for your power needs. Unlike standard rechargeable batteries, the Eneloop Ni-MH batteries are capable of holding their charge much more efficiently and will retain 70% of a full charge after 10 years unused. This allows you to charge them up to 2100 times regardless of their remaining capacity and be confident they are performing at their peak efficiency. The charger is small, lightweight and has been specifically developed for Eneloop batteries. The Panasonic Eneloop 1.5 Hour Quick Charger kit comes with 4 pre-charged Eneloop AA batteries and is capable of recharging 2 AA batteries in approximately 1.5 hours compared to the 10-hour time frame of the Eneloop standard charger. Another key benefit of these batteries is that they work in temperatures as low as -20°C.
