This is so funky I didn't know what to put in the subject line. Anyway, I received an email forward telling me a tired dry cell battery, in this case it's a AA size, will bounce a few times when dropped on it's bottom end and a fully charged one will land with a thud without bouncing. I've never heard of this. Maybe a bunch of you guys have, but not me.
So I tried it a few minutes ago. The two Duracell AA's alkys in my electric toothbrush died so I took them out, held them 2" above the desk and dropped them on their bottom ends one by one. Both of them bounced two or three times before coming to rest. Then I took two fresh Duracell AA's and dropped them the same way. The new ones lit with a thud and just fell over without bouncing. I did this over and again with the same results.
I know what the inside of a battery looks like but I'm not a chemist in any way. So what kind of an explanation can you experts give us? Density is probably at play here right? Jim
