I work as an IT person, I know a shop that repairs A/C forklift motors.
Tey have no idea what make or model it is.
You give me the info and i undrestand if it does not work it is not your fault.
Cash talks what do you want for the information?
Used batteries or cells are usually a crap shoot. I couldn't say what they're worth. It depends on brand, source, age, condition, etc. I suggest you post a classified at your numbers OBO (or best offer). Good luck.
