RegenBox - An alkaline batteries regenerator for single-use batteries that reduces battery toxic waste, economic ownership cost, and the ecological footprint

RegenBox is a collaborative research program aimed at any consumer using alkaline batteries for personal or professional use to regenerate them, although they are supposedly "non-rechargeable". By re-inventing from a patent fallen into the public domain, RegenBox was launched in 2017. RegenBox is the first DIY battery regenerator which reduces the tons of batteries wrongly thrown away. It is capable of regenerating LR6 and LR3 batteries using microelectric pulsions and in the future will be able to regenerate any type of “single use” batteries. RegenBox is designed to be environmentally friendly and against programmed obsolescence. To use RegenBox, users simply have to test the batteries, and if they are in the rechargeable range (0.9 - 1.4 Volt), users just have to plug the battery into the RegenBox and plug it to an electrical source.
