New Battery for Winch

Funny....most of the heavy equipment I have dealt with use two-12V batteries in series for 24V. The alternators are always 24V.

I can't imagine that highway tractors are much different. The higher voltage just works so much better for everything.

The only 24v system I saw that was different from this was on a Russian farm tractor I have (a Belarus). It uses 24V on the starter but charges at 12V and everything else was 12V. It has some weird wiring to accomplish this.

Modern semis are all 12 volt, with maybe an exception of semis built for the military, period.
