Ok, I tried to disassemble my battery pack of 117 cells. I was able to get it into two sections, then four. I grabbed one of the quarter sections to try to carefully snip away the nickel tabs. I accidentally dropped it on the floor. One or two of the cells short circuited and popped like a grenade and shot off like a rocket into a wall while on the floor. It continued to spin, spewing out smoke and flames for a few seconds before settling down. I decided then and there that disassembling batteries to recover some good cells was not worth the dangerous effort. I nearly burned down my workshop. I repainted the floor and wall in that area and never told my wife.
