If any of you have ever purchased a sex toy (vibrator) you may have had the clerk tell you not to use duracell/energizer batteries because they will prematurely burn out the tiny motors -- instead you should buy some off-brand batteries from behind the counter.
I have been told from various clerks why this is the case. 1) Name brand have too much alkaline and 2) Name brand have too much mercury.
Can someone tell me is this a myth? If not, why is this the case?
The only thing I could come up with is that the name brand batteries have a smaller resistance and therefore provide too much current. My only issue with this is that the vibrators have potentiometers for speed control and I would imagine that the resistance of the potentiometer would make the resistance of the battery negligable.
I actually got in a debate with the clerk today when buying a toy... She was not convinving even though there may be some truth in what she said.
Thanks
