Best Options for X41 Battery Replacement / Rebuild?

[Mr. B]

First let me say I tried a search but "battery" is a banned search term.

I recently bought an X41 (not a tablet) from a friend and it came with a third party battery that lasts 2 minutes. Yesterday I received a used four cell OEM battery from IBM (92p0998) but it only hold 60% of designed capacity.

I gutted the third party battery to explore the possibility of a battery rebuild which I've done successfully in the past. So far I have not been able to determine what type of cells these are. The printed numbers on one read 1005 70504, R72F13. Searching those numbers yielded nothing.

I just want a good battery. If there is a trusty third party replacement available I would love to know about it. Alternatively, If anyone knows what kinds of cells are in the battery I should be able to find some to rebuild a battery on the cheap. Any assistance would be much appreciated.

They are a common type of cell, but just replacing the cells is not enough.
Once power is lost to the controller chip, it might not work again.
