Re: Talking battery meter

I don’t know if this is the same battery tester I saw many years ago but it makes sense that a battery would power the unit.  In the one I saw, an oscilator sounds and you can tell from the pitch of the oscilator if the battery is in good shape or not.  But something needs to power the oscilator independent of the battery being tested.

Um, so you have to use  batteries to power the tester to test batteries? Weird...

This battery tester is from the Blind Mice Mega Mall and I've owned it for about 4 or 5 years.  It's about $79 which is a little pricey, but it works like a charm.
