Hello Howard, Nathan and (possibly) others:

I have been doing this (rebuilding and replacing the cells) for my own
PB 5X0s and Duos for the last several months and have learned a few things.

I would like to try rebuilding your batteries for you, but I before you
reply to this (off list, please), there are a couple of things you
should try to _truly_ recondition your batteries.

1.      Get the battery utilities Battery Amnesia 1.5.2 by Jeremy Kezer (
<http://www.kezer.net/shareware.html> ) and EMMpathy 2.0 or 2.1 by VST
and Intelligent Battery Recondition (IBR) (for Intelligent batteries, PB
5X0s) by Apple.  If you can't find any of these let me know and I will
send them to you.

2.      Start up the PB on your AC power supply and start up IBR _without_
the battery inserted.  Then insert your battery.  If IBR doesn't like
your battery, shut it down, take your battery out and restart IBR.  Do
this up to 10 times and allow the program to charge your battery each
time.  You should be able to get enough charge during this process to
allow the battery memory to be read.  Then let the program continue
processing your battery.  You can also use a stock battery charger of
about 9V and 150 millamps or more up to 1 amp to manually charge the
battery (You will need to devise an attachment method, but I can help
you on that).  Once you have the battery charged, you need to drain the
battery using Battery Amnesia and fully charge it back up about 5 times
or until you see no further improvement in battery life.

If the above works, it will need to be repeated about once a month
(about 2-3 charge and discharge cycles) to keep the batteries at full capacity.

However, even if this does work, (so far, about 50% of the time for me)
old batteries will _usually_, not always, lose from 5 to 50% of their
charge each day regardless of whether they are in the PowerBook or not. 
A recelled battery will lose about 3-15% _per week_.

Please let me know what you would like to do.

Sincerely yours, Grizzlygiant
