These were NiMh cells, and you can just about weld with them. A good cell can deliver as much as 30A and only drop down to 1V. You wouldn't be able to do that on regular use before the cell is destroyed, but they can really deliver current.
I dumped some AAs into my left hand once and was instantly burned as my wedding band made contact across the positive terminal and a nick in the insulator on the battery body. The gold in the wedding band is an excellent conductor of heat and electricity, and I was burned all the way around the ring in a matter of seconds. My wife thought that would be a great invention to cure a wandering eye, sort of like an invisible fence.
Yup, you and my husband. I bet if you see a foreign substance you stick your finger out and touch it and then sniff it to try to determine what it is. In some ways I will never understand the male gender! I'll never forget the time we went on a rock hunt out on a ranch and when we brought our treasures back to the grizzled old guy that ran the place - he would hold up each of our rocks to examine it, and on some of them he would lick it as part of his examination, Yeccch.....but the guy sure knew his rocks. He could tell you everything there was to know about each one.
Yes, so do I, Deejayh. Once you've done it a few hundred times, you can tell if the battery is weak, medium strength or brand news. When I was a kid my parents thought I was nuts for doing it. Later on, my kids thought I was nuts for doing it.
A double A battery will give your tongue a small tingle when new. No, my tongue isn't 4" wide/long. Apply your index finger to the negative terminal (flat end) of the battery and touch the other end (+) to your tongue. A bit of moisture on the end of your index finger will increase the effect. So, if your a bit too squeamish to try a 9V, give this smaller dose a try.
Our company requires us to tape the terminal ends of all batteries before placing them in the battery recycling bucket.
