5300c battery questions

Hi, I got an old Powerbook 5300c that was sitting on a shelf at my school for who knows how many years with an exploded battery. Does anyone have a 3D model of the battery enclosure to 3D print (not a big deal if not because I have a friend who's good with Blender who can help me), does anyone know what the black component attached to the batteries farthest from the contacts is, and the last contact to the right has detached, it doesn't seem like anything was soldered to it, is it needed?

I believe that is thermal "glue" to help with identifying the temp of the cells as it approaches the charge limit.

I think someone used a tiny thermal pad (double sided adhesive) as a work around.

I have not seen a 3D STL for the battery pack, but, I would be interested in it as well. When I recell'd one of my units, I used 2500mah EnLoop cells that I managed to use a home-made spot welder to attach new nickel tabs to.

It still works after 3 years, but, I need to rebuild my power board (needs new caps).

the thermal “glue” is the black component? i found some korean website that seems to be selling it and according to google translate its an 80c temperature sensor

That sounds about right.

I used a thin strip of Gorilla Glue tape (black stuff) to hold the sensor onto a teeny-tiny bead of ArticSilver paste.

The only thing that is important is the side that comes into contact with the cell. The other side is irrelevant.
