The IBM ThinkPad 600 battery uses six Panasonic Li-Ion cells in a 3Sx2P setup, and has a battery controller onboard the pack (under the lump covered by the IBM label). The problem has been that controller which limits the maximum energy output, especially if the pack is too hot. It has a fuse and a thermistor in between the cells. if the controller sees low voltages , the pack will be “open” yet the cells can still be good.

I have opened a pack manufactured in 1996 and the cells were good, such that I have recharged each cell pair directly. If you still have a ThinkPad 600 and several bad packs, open them carefully with a sharp blade along the plastic clamshell, remove the bottom, turn the pack with the label facing down, get a regulated Li-Ion cell charger, attach it carefully to the ends of each pair straps (the cells are welded together), and charge each pair until they have a minimum of 3.2 VDC each (or let it charge up to 4 VDC). Then tape the clamshell together and plug the pack in.
