Weird cell degradation

[pinkpanda3310]

I took the top cell off today. Before doing anything I put the multimeter on it, the voltage bounced up and down like a yoyo. At first I didn't know what to think but after fiddling with the +tab (swollen end) I realized there was a poor connection inside the cell. Pressure it one way and the voltage was zero, pressure it the other and the v=~3.7. The movement within the cell seemed to better the connection cause it then held a steady 3.74v. So it is not quite as dead as I was anticipating.

How do I drain it? From memory I think your surposed to dunk it in salt water for a day or so.
