Can it work?

\'Explaining exactly how it works would require a doctorate in physics and chemistry\' claim Home Computer Magazine; well you\'re in luck bit-tech reader, because it just so happens that I\'m about a month away from writing up the thesis for my physics Ph.D. and to be fair there\'s some chemistry in it. Lucky for you, not so lucky for Batterylife, who won\'t be pulling any wool over my eyes with bad science.

After many charges/discharges batteries deteriorate, though not nearly as badly as they used to. Batterlife claim that in Lithium Ion batteries (the type of battery most commonly found in rechargeable gadgets these days) the main cause of this deterioration is a build up of inert, uncharged particles between the electrodes. I don\'t know a lot about batteries but it sounds reasonable, all that\'s left is to examine is how the Activator is supposed to solve the problem. Here\'s where the science gets fuzzy... \'The Activator creates around it a high density of ions\' and on a separate piece of paper Batterylife add some numbers ...35 times greater ion intensity surrounding it (7000-8000 ions per cm3) compared to normal air (200-300 ions per cm3)\'. These extra ions are supposed to attract the debris that\'s built up in the battery\'s electrolyte, effectively cleaning it and making the battery like new.

Batterylife's Activator How does it work?

With a little science you might be worried at this point, we\'re talking about uncharged particles feeling a force in a weak static electric field here, the reason they\'re a problem is because theyre not attracted to the electrodes. The numbers claimed are ridiculous, 8000 ions per cm3 is nothing, if you were doping a semiconductor and managed 10^10 (10,000,000,000) extra electrons (or missing electrons, holes) per cm3 you wouldn\'t even bother to call it doped...putting some numbers in and calculating the electric field created by a monopole density of 10^4/cm3 over the width of the battery and you get a very small number indeed.

I\'m certainly not debunking the product on test here, not without testing it (which we\'ll be doing shortly) but I will go so far as to debunk the explanation of its working that I\'ve been shown, it makes no sense. It\'s likely this is because the person who wrote it didn\'t understand what they were writing, but it\'s a worrying sign for the product.
