DESC: Renu-It is a professioal grade disposable battery regenerator. It can regererate NI-MH, Ni-Cd and Alkaline batteries from 2.5 hours to 7 hours depending on size of battery. This is how it works, the chemical reactions within the battery cause electrons to be stripped away from the carbon electrode so electrons will try to flow from a battery's negative terminal to its positive one, if allowed. As a battery is used this cell gets "disorganized" as electrons get jumbled trying to make their way to the positive terminal. The Renu-It Pro "reorganizes" the internal structure of the battery cell allowing it to be reused up to 70 times.
