Usually how battery packs die is that one of the cells becomes very weak (this case), or goes high resistance (completely dead pack), or shorts internally (you lose the voltage from one battery but the pack will still work so long as the device can survive with much lower voltages). And basically that cell will go from about normal voltage 4.2V (or whatever it is being charged to) to close to 0 quickly. This causes a sudden abnormal drop in the pack voltage and does not match the normal voltage/capacity/discharge curve so not really predictable. The solutions are to get a new battery pack, or carefully take the current pack apart and figure out the bad cell and replace the bad cell with a new similar cell. You can typically get a 3rd party battery for a reasonable price.
