Thread: What kind of battery?

I don't remember TMs that ran on 6v, so any 12v battery should work fine. Heavy duty TMs in the 70s could use either 12v or 24v, so if there's any indication this motor had that capability, you could use 2 12v batteries in series. The best batteries for all TMs, regardless of age, are deep cycle.

Cray- I'll defer to your experience or recollection of the TM products available during those years.
