Check out these sweet old batteries I found inside a medical device today.
True to their word, they haven't leaked. They must be >30 years old.
9 Lives!
@wohali almost certainly much older than 30 years. I'd say older than 50.
@MightyBigCar I remember the logo from when I was a kid...that's why i said 30, but I probably should have said 40.
Remember that graphic design in Canada severely lagged behind that of the US for a long while.
I do think they are alkaline batteries, though.
