of the copper traces on circuit boards and etch the metal leads off components.

When the battery vents, the material can make its way throughout an appliance
enclosure and given time, the damage can be irreparable.

This is the primary reason all battery manufacturers recommend removing batteries
from appliances when they won't be used for extended periods of time.

Wash your hands well if you come into contact with it.

Great explanation, thanks.

I'll be taking another look at it all on the weekend coming.
