BATTEROO Batteriser is a reusable sleeve that slips over new or most ‘used’ batteries and instantly taps into the remaining 80% of energy that is usually thrown away. The result is batteries last up to 8x longer. Crafted from stainless-steel at less than .1 millimeters thin, product is designed to easily slip over your battery and fit neatly back into your device. Product is able to access that wasted energy much like a drinking straw allows us to reach the bottom of a glass. Product can also be used with new alkaline batteries for similar savings and performance gains. Product will be available for AA, AAA, C, and D-cell batteries.
