How should I repair my laptop battery?

[Robuck]

Hello,

I bought a compaq LTE Elite 4/50CX a while ago, and I have been using it more and more for all sorts of stuff. Using it plugged into a wall is great and all, but I would really like to use it on a plane or in the car. Unfortunately, the battery that it came with was completely dead and wont hold a charge at all. Is there some way I could fix the battery so it will hold a charge? Or maybe just take out all the components of the battery, and put new batteries inside it and connect them to the terminals? Im very new to vintage computers and electronics, so any help would be greatly appreciated!

Thank you

First thing is to open the pack without too much damage; inside are 10 x 4/3 NiMh cells like this (preferably with tabs):

Just copy the original, being careful to put the thermistor(s) and fuses back the same way.

Thanks a bunch! I just ordered the new batteries. It thought it was going to be way harder than this, but it's actually pretty straightforward.
