Looking for manual for Ericsson Battery 6614

[Cactii1]

I was able to acquire four 2-3 year old Ericsson 6614 server rack batteries (51.2v 100ah) that are normally used in 5G installations for backup power.

I can't find any manual for them or any details about them on the internet and am hoping that someone might have something on them.

Please share if you can.
