I have had Lithium batteries go to zero and refuse to charge. The 
solution was a very slow low charge for about 20 minutes. This put in 
enough charge for the charger to start charging.

This is very, very likely a broken battery.  No Li-ION battery I have ever
seen hits 0V on its output, unless it is still in "factory shipment mode",
and that mode actually goes to the trouble of disconnecting the power output
terminals (unlikely, AFAIK).

So, I find it very unlikely that any ThinkPad battery with 0V on its power
terminals would be anything more than an useless brick that a trip to the
nearest safe-battery-disposal unit to get rid of.
