Eneloop BQ-CC16 Charger + Rechargeable AA Battery BK-3MCCE x 4

Quick Charger Plus Four AA Rechargeable Batteries.

The Eneloop 2 Hour Quick Charger (BQ-CC16) with 4 AA Batteries (BK-3MCCE) is the ultimate kit for your photographic 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 5 years unused. This makes them ideal for sparingly used gear such as Speedlights, wireless flash receivers and transmitters. Eneloops are also advantageous in that they have no memory effect. 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.
