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."

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

    Well, he says that big institutions like Osaka University, NTT DoCoMo have certified this sticker. How could the BatteryLife people have managed to get this certification. Isnt someone smelling foul play or something? Cant they be sued over this?

  8. Flawed Results by kevlar · · Score: 5, Insightful


    I hate to say it, but he has flawed results that do not demonstrate that the sticker is a placebo.

    He used only one battery to do his test. He should have used two; one with the sticker and one without. By only using one battery, running 3 tests, then putting the sticker on and running a 4th test, he's introduced an additional variable into the equation. It could thereofre be argued that his graph (http://www.dansdata.com/images/batterylife/activa ted.gif) showed that the sticker IMPROVED the battery life (because it WAS an improvement over his 3rd test run).

  9. From the article . . . by jhylkema · · Score: 5, Informative

    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.

    DUH the test was a waste of time and everyone here already knew it was BS, but people, have you SEEN the "cow taser" page linked to from the review article?!! I think I just pissed myself from laughing so hard.

    Then it wasn't exactly a waste of time, was it?

    Part of the reason people read Dan's stuff (just in case anyone missed the main link to his site) is his entertaining writing style. I almost always learn something from his articles, even if it's got nothing to do with what the article's supposedly about. Dan is obviously fully in on the joke himself or he wouldn't even be linking to things like cow tasers in his articles. It's people like you - who think reviews have to be a "waste of time" simply because the products in question are such obvious bunk - who don't seem to quite get it.

    In a world where product reviews often offer little or not information at all, and where the strongest and most specific statement you might read is how one product or another is vaguely "generally good", writers like Dan are a refreshing change - he writes pieces that are always entertaining in and of themselves, often more informative than they need to be, and with plenty of useless but interesting trivia to keep you interested when the product in question is less than worthwhile. I only wish he'd review more stuff that I'm actually interested in buying (though I've become interested in buying a few things I would never have even known about but for his review).

    As for this particular review, I think it's worth reminding the Slashdot crowd of the dangers of pseudo-science every now and again - pseudo-scientific articles do occasionally slip through the editing process here, and are often accepted as fact.

  11. Slashdot chewed over? by Slashcrap · · Score: 5, Interesting

    Bit of revisionism going on here isn't there?

    Slashdot didn't "chew over" the original story. Slashdot simply re-posted the company's bullshit press release in it's entirity.

    Was the story posted in the funny section? No.
    Was there any comment from the editor regarding the product's obvious scam factor? No.
    Was there an update to the story to say, "Whoops! We got suckered! Sorry." No.

    So you see Slashdot didn't chew it over - Slashdot swallowed it whole.

  12. The sticker + instructions works great! by ltbarcly · · Score: 5, Interesting

    Of course the sticker works, when used as directed. Then again, if you power cycle a lithium ion battery 5 times it will work the same as if you power cycle it 5 times with the sticker.

    You see, the instructions quoted in the article tell you to fully charge and discharge the battery like 4 times.

    Here is why:

    If you discharge a lithium ion battery completely to 0 it could explode when you charge it. So there is a meter in the battery (usually) or on the logic board of the phone (not usually) that prevents total discharge. That is, at a pre-defined level of discharge, it turns the phone off. Now, the meter can get out of callibration. When you fully discharge and recharge the phone it can put the battery meter back into calibration, and doing it repeatedly will fix it better.

    So you see, you might get up to about 30% more battery life, because the meter is out of whack and is cutting off your phone when there is still plenty of charge.

    Basically they are selling you the instructions to fix your battery, plus a sticker that does nothing.

    Computer batteries are the same way.

    Disclaimer: Fully discharging Lithium batteries is bad for them. They do not develop memory like other battery types. However, when the meter is out of calibration it pays to do this a few times, just don't over do it, since you only get between 500 and 1000 full use cycles out of the batteries regardless of what you do.
