Rechargeable batteries are almost crucial for Xbox 360 players, as the AA batteries seem to die fast. While there are many on the market to chose from, one of the best is the Sanyo Eneloop rechargeable battery. Breakthrough technology has allowed these NiMH rechargeable batteries the ability to increase electrical capacity, reduce self-discharge, and maintain longer charge cycles. Most Xbox 360 players notice that they are able to play games longer on a single charge, compared to other rechargeable batteries.
