If you’re like us and have a drawer full of drained alkaline batteries that you’ve been hoarding just hoping they’ll somehow be usable again one day, we’ve got good news for you! WattsClever is a new kind of battery charger that allows you to recharge those dead Duracells – yes, even the regular kind that you usually need to take to a Best Buy to recycle. The new device uses a “microprocessor to minutely control the trickle charge so the batteries don’t overheat and die.” Depending on the age and quality of am AA or AAA alkaline battery, it can be recharged anywhere from 10-20 times and each recharge takes around four hours.

Isn’t this the same technology from over 20 years ago that they used in those “Renewal” rechargeable alkaline batteries designed with thicker casings to prevent leakage? I used the same charger on my “regular” alkaline batteries, which worked for the most part, but occasionally a few would “pop” and release a toxic white substance.
