Panasonic R6-AA Industrial General Purpose.
The neighbor who gave them to me says they are rechargeable.
The skeptic between my ears says: ask here first!
They are @ 1.5V each, per my MM.
Blue / silver / gray.
Exp. date? on the (-) end says 09 2013.
Made in Indonesia.
Caution statement says: 'May explode or leak if recharged improperly, mixed with different battery types or disposed of in fire. Do not open battery.'
Yeah, I know....sounds like they are.
But I didn't get this foolish by being old....
Thanx! in advance, for your input.
