IBM T23 Notebook battery Li-ion

This looks like an amazing site, I just found it today.

IBM T23 Li-ion battery. This battery will register as being fully charged, then when in use, 20 min in will immediately register 5% charge. The battery is getting tired, as all things eventually do. Right? Well, not wanting to pay the price of an all new pack, I looked into renewing the cells. Well after doing a little research on the Li-ion batts, ( from this great site, I might add) I found out that cell discharge stops @ 2.3v/cell via the "smart" tech in the pack. However, the per cell voltage in my "dead" pack is 3.96v. I watched the battery monitor on windows indicate the power drop, yet when my multimeter is showing 3.7v/cell under load with the  laptop speakers playing music, I et 'kinda suspicious.

What gives?

Are the batts. toast? Or is it the circuit board? Or what...

Any way I can easily test the batts. for health?

Thanks for your help...
