Since it relies on proprietary eneloop technology, the XX can be used right out of the box as it retains up to 75% of its charge even after one year of storage – according to Sanyo, anyways. Coming in a package of four AA batteries, it will be available for $24.99.
The XX powered by eneloop is able to deliver 25% more power for extreme usage requirements, and to sweeten the deal, you will be pleased to know that the XX batteries can still deliver juice even when temperatures drop down to -4 degrees Fahrenheit – now how about that for performance?
