I went out of the country on a work assignment and was supposed to be gone 3-5 weeks, was actually gone almost 13weeks. All the lipos I had were stored 1/2 charged. They all puffed, but only the cell on top. The cells that were on the bottom appeared fine. Decided to try to salvage and rebuild using the good cells.

Mine were glued together so aggressively, I couldn't get them separated without damaging the cell membrane. I never got the the point of having to deal with the wired end either. I thought cutting the shrink off would be all there was to it, but not with these. They must have been epoxied or something. Maybe yours will be diff.
