AA and AAA batteries have countless uses around the home – - and as a result, countless dead batteries end up in landfills each year. “Low Self-Discharge” rechargeable batteries like the Sanyo’s Eneloop offer better performance in your gadgets than other rechargeables – and they stay out of the trash can.
Eneloop batteries just celebrated their 5-year anniversary, and in our opinion they are the most efficient rechargeable batteries on the market. They utilize a nickel-metal hydride (NiMH) cell with improved internal design to maximize their shelf life (holding up to 75% of their juice after 3 years of storage).
Eneloops are pre-charged and ready-to-use out of the package, and Sanyo states that this newly improved version can be recharged up to 1,500 times (including partial charges with no risk of memory effect). C and D battery adapter modules are available too, so Eneloop AA cells can be used in devices that require larger battery sizes.
