Hi,
Thanks for all the info. Apparently there are no reliable way to bring their
youth back, I would like to have a reliable laptop with a battery that last
more than 30 min. I found a Zenith z-star 433 VLp (500 Mb hd, 12 M RAM and
color display and the Zenith J-Mouse!!!) that I'd like to use while away
from home. The batery I got seem to work for a while. Also it has four
contacts does this means that it provide mutiple voltages or is there some
kind of charge sense signal? I haven't brought the battery to the bench yet
(no room on or near the bench:).
Also the pack seems to be sealed pretty good, any elegant way to open it up
and reclose it without too much damage?
Thanks
Francois

PS: I actually got 3 of these laptops and built two from the set of parts
and two of the batteries are totally shot: they get very hot when I try to
charge them and of course no juice is coming out. I can practice on one of
the dead ones.
