Hi,
Yes, another battery overheat issue. This time it I couldnt explain it at all. Basically, I had 4 AA battery in a standard case. I wrapped around some black tape to avoid the contacts touching any of of the other circuitry on my robot.
I had not connected the battery terminals to anything but when I was installing the battery pack onto the robot, all of a sudden I could smell a burning odour. I immediately checked my soldering iron if it was on but it wasnt. I had not suspected anything on the robot itself to be burning.
Then I noticed how the battery pack in on my robot was emitting smoke and the plastic case was melting right in my hand! Small molten plastic particles dropped on my hand (no injury) and I was sure this thing is way hotter then I would ever want it to be!
I immediately tried to unwrap the black tape, the end bits (connected to + and - were melting), so that I could take one of the cells out quickly.
A later battery case inspection reveals that most of the end terminals of the case had melted away with one or two intact.
This was an unusual phenomenon, and a dangerous one at that! Anyone else experienced the same? Any one know of reason/s why this could happen?
Thanks,
peace.
