Battery ID for a PMAT 2000

[Jwalling]

Hoping someone recognizes this battery pack. I don't have the originals.
Just short of 9" long or so... 2 battery packs in each unit. Located under the hard drive/floppy.

All I know is that it's Li-Ion. the opening looks familiar, but scouring Ebay got me nowhere.

I would say try to contact Teledyne for batteries replacement, or try to have some numbers ??   googled this thing, never found any battery number nor description ??

They ressemble some terminals std pins,  maybe you could try to build some battery pack   but i see some battery sense pin

Teledyne may be the next place to try. I've requested a quote for this, but no response yet:
