What Happened To Duracell PowerCheck?
(hackaday.com)
This is a most excellent place for technology news and articles.
My dad used to just put them on his tongue for a power check. Not entirely sure how that worked. Personally I just use a multimeter.
You can do that with the 9 volt batteries and feel how much "tingle" they have, but never heard of it working with aa batteries. Wouldn't he have to stick the whole thing in his mouth to complete the circuit?
It's pretty shocking, but I can fit 2 Ds in my mouth.
Your mother must be so proud.
ah, I love it when mothers teach their kids valuable skills
-Are you testing batteries again? -(with my mouth full) nogh
I did know a girl in college ......
Even if you did (don't eat batteries), the voltage range is much lower and you probably wouldn't feel anything.
Yeah. Doesn't make any sense honestly. I think he thought he could power check it but didn't understand the actual mechanics of how it works. Glass onion eh.
I do this with AAs. Basically put the side with the bump (positive) on the tip of the tongue and touch the flat (negative) side with a wet finger. It gives out a mild but distinctive 'taste', not enough to tingle but definitely something I am able to notice, when the cell has decent juice.
