Where can I get a step by step plan, and parts to rebuild my IBM
Thinkpad Battery?  There has to be a less expensive way than
purchasing a replacement

That appears to answer the question however, it is a bigger pain than
I hoped it would be.    Thanks for your advice

Hi mraddatz,

I'm glad I was able to locate the information you needed.

If you're connecting batteries in paralell (positive to positive,
negative to negative), make absolutely sure that the batteries are
within about 0.15 volts of eachother -- otherwise, the battery with
the higher charge will charge the lower battery at a dangerous rate.

Oh yeah, put a 100 ohm (1/2-watt or better) resistor across the higher
pack for a while to bring it down to the same level.  The resistor
will produce heat as it discharges the battery (at a safer rate).
