Handy trick to tell if an alkaline battery is good


Recommended Posts

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.

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!!! :ROFL:
