Were they in series? If so then the 0V cell has likely been reverse polarised 
with can be seriously bad for the cell.

A recharger likely won't want to try charge it until it gets to a reasonable 
voltage. Try trickle charging at a few mA for a while and see if that gets it 
back into charging range.

NB Given the bad things that can happen with Lithium in the picture, only fool 
around with these things outside and away from anything that you care about.
