The laptop batterys have nice Gold contacts. Id expect a thicker plating too.

One morning in bed, I hear a loud 'snap/bang' sound somewhere in the house. I relised Id heard this before too.
Then one day I open a container with some button cells in them and find a couple of little discs and two empty button cells...
I expect they had touched, shorted out, got hot, and exploded.



Can you use a sheet of, dunno what you call it, the plastic you stick to the bottom of kitchen cupboards and stick the batterys to that, all the same side up and then stick another sheet over the other side?
