Default NiMH Rebuild?

Anyone here done a NiMH rebuild? I have some ancient batteries from '01 (they literally have the ACROS code name on them) that I'd like to take a stab at rebuilding but would love any advice.

Also have a set of Lithiums that were "rebuilt" by MTO, but only throw red lights.

Often with the nimh batteries the chemicals will corrode the bms board.

some repairs can be made but they start to conduct internally along the vias inside then pcb.. and eventaully fail, even with new cells it won't work.

I have new boards just waiting to be built and I use nickel cells alot I don't want to be without.

However, it is often just the cells that are unservicable..
