Well, at least the Duracell bunny was just as misleading, by comparing an alkaline Duracell battery against zinc-chloride batteries from other brands (in 2014!), and then giving the impression that it was outlasting 12 other batteries in sequence, when it wasn't even doing that: http://www.thegrocer.co.uk/buying-and-supplying/advertising-watchdogs-silence-duracells-drumming-bunny/373910.article
There must be many versions of bunny commercials by now, haven't seen that one.
We considered the test data provided was not sufficient to demonstrate that the advertised product lasted longer than 12 leading zinc batteries consecutively used, in general usage, based on tests on a representative device. We therefore concluded that the ads were misleading.
That's how it's supposed to work. I wonder if there is something similar in the USA?
But it's not nearly as bad as the batteriser IMO. While misleading and the figure 12 might be BS it's still no secret that alkaline batteries last much longer than zinc cells (
on average about 6x according to this old radioshack FAQ ). If you put two Duracell bunnies side by side, one with crap zinc battery and the other with
Duracell ultra power with duralock , the duracell one will outlast the zinc one by many times (even if not twelve). So the duracell advertisement might have been exaggerated and misleading but not a butteriser level scam.
Batteriser claims they will extend batterylife up to 8x, while most likely it would drain the batteries
faster in most cases, unless they have come up with some nobel prize winning new physics. We all know what would happen with two monkeys, one with a batteriser and one with normal battery: the one
without the batteriser will last
longer since the monkey is an unregulated resistive load. So the batteriser claim is completely nonsense. In most cases it will be detrimental: higher risk of leakage, breaks the low battery indicators, drains batteries faster, etc. etc... And I'm sure the inventors know this, either that or they are so incompetent they shouldn't even be teaching electronics at gradeschool; this is a tenured professor at a university who doesn't understand you should measure battery under load?
