kkelly5 I don't see how this method would charge alkaline batts. Toothbrush batteries are charged by mutual induction with the base and toothbrush working like a transformer. The base is the primary and the toothbrush secondary. inside the toothbrush is a charging circuit, bridge rectifier, capacitors etc. The base could heat the batteries but i don't think that's the same as recharging.
