Daniel Rutter writes "Slashdot chewed over the BatMax Battery Life Booster - a nanotechnomagical sticker that's meant to rejuvenate lithium ion batteries - a while ago. Now I've reviewed the strikingly similar Batterylife Activator, and subjected it to actual empirical testing, with automated datalogging and everything. The results confirmed my original suspicion -- that the local Batterylife branch made a serious error of judgement when they decided to send me their product."
