Want to help keep the earth green? You can now do so with the Alkaline Battery Regenerator. While this device is not meant to be used as a battery charger, it allows you to reuse disposable batteries, giving the standard alkaline battery another 100 rounds of use before being disposed off properly. The Alkaline Battery Regenerator works with both AA and AAA batteries, regenerating up to four batteries simultaneously. Built-in protection against overcharging, overheating, short-circuiting and polarity reversal helps you maintain your house fire insurance without increasing the premium. At £14.99, it sounds like a pretty good deal to me and for Mother Nature.
