I didn't realize that they were welded. I've never needed to remove one before. I'll just use a battery holder on the cartridge I'm designing.
Just out of curiousity, do you think a lithium battery has a shelf life? It would be such a waste to buy 600 batteries and have them 'expire' in 5 years or something if you never got around to using them all.
Actually, what's the life expectancy of a battery in a cartridge?
Well, thanks for the info.
P.S. How much are these batteries costing you?
