Here are some notes on keeping Julene's old Dell Inspiron 4000 alive. It was shipped 6 March 2003.
There is some good information on this at the link below. In particular, look at "Removing and Replacing Parts."

Check out the link below; this is exceedingly easy as compared to other Dell
notebooks.
The battery reference appears to be Varta 7.2v 15mAH Ni-MH 6/V15H.
This is configuration 6×1; other configurations (3×2) are also
possible, but won't fit without lengthening the conductors and placing the
battery elsewhere.

Supplier: Ambry International, Ltd., Addison, Texas. Let's hope this is the
part.
