Batteroo Battery Life Extender

Batteroo Battery Life Extender


The Batteroo battery sleeve promises to extend the life of your batteries up to eight times longer by drawing out their remaining power -- which you were about to throw in the garbage. (When disposable AAs stop working, they actually still have about 80% of their power remaining).

Batteroo is a simple device which could revolutionise the battery industry.  This product extends battery life considerably by tapping into unused efficiencies (up to 80%) and is extremely environmentally friendly - reducing the waste of batteries and land-fill.

The tiny, 0.1 millimetre-thick stainless steel Batteroo sleeve features an incredibly small circuit board, built to tap into the battery's remaining energy.
