Batterylife Activator Reviewed

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."

Cheap is best

Actual tests of batteries always show that the cheapest batteries are the best value for money, in terms of watt hours per dollar.

I hadn't noticed, until your post made me go back to look, that it was Dan's Data - the source of one of the best reviews I've ever read...

Assuming, for the sake of argument, that the Activator doesn't work, how come so many people say that it does?

It's very simple, really. Placebo effect and confirmation bias. These things drive all manner of quackery (naturopathy, chiropractic, acupuncture, etc.) and other pseudoscience. Confirmation bias is particularly powerful here as people don't want to admit they're stupid enough to have been duped into buying an overpriced sticker, even though they are.
