|How to open battery-cabinets|
Message #1 Posted by Karl-Ludwig Butte on 2 Aug 2008, 5:14 a.m.
I have some old battery packs from different calculator models, all with damaged batteries. The problem I'm facing is not to get new batteries but how to open the plastic cabinet in which the batteries are packaged. I tried a sharp scalpel-knife and a small cutting disk. With both methods I was able to crack the plastic but the edges look terrible. Instead of a straight smooth edge these methods produce serrated edges which makes it nearly impossible to put the cabinet halves together again.
How are you guys doing this ? What's the best practices to open these battery-cabinets ? Thank you very much in advance - any hint will be very much appreiated.
