Batteriser is a device that increases battery life for up to 800%. Batteries that were once doomed for the trash can, can now be revived by placing a tiny sliver of metal device over a battery cell. This device acts as a sleeve and it’s thin enough to fit nicely in any battery compartment in any electronic device. The metal sleeve will sell for about $2.50 each. You can get a pack of 4 for $10. Eight times over the regular battery life is quite amazing. Duracell, Energizer and Maxell are probably not too happy about to hear about this innovation.
