Handy trick to tell if an alkaline battery is good

[Uncle Ron 1,216]

I just learned this trick to tell a good alkaline battery from a bad one: Hold the battery upright about 1-2 inches off a solid surface ... Drop it negative side down ... A good battery will more or less just "thud", , but a bad one will bounce several times ... Has something to do with density of the stuff inside the battery ... I had a box full of batteries and was quickly able to sort out good from bad.... Cheers, Unc

Haven't heard of that. I just use a cheap(( got (3) free Harbor Freight MUltimeters)). BElow 1.1 volts, it's not long for this world.

If you can verify with a multimeter, I think you 've got a winner.

The link is interesting.

Maybe not

If you drop a re-charageable battery you run the chance of if not working any more.

I use a cheap radio shack battery tester. It opens up and you put the battery in between the two contacts and it tells the charge.

And here I was thinking that was what Volt Meters was for. Emmmm.

I have always from a young age tested 9 volts batteries using the tongue trick , it's always worked for me, as shocking as that may be!!

I'm trying really hard not to say what I'm thinking!

Don, I never really liked doing the tongue test, still don't, I only resorted to doing it if I couldn't get one of my brothers to do it and later in life my kids!!!
