Batteroo Battery Life Extender

Batteroo Battery Life Extender

£14.99

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.
