Common electric starting systems for diesel engines;
12volt - one or more 12v batteries wired in parallel,
24volt - two 12v batteries wired in series,
Series-parallel - two 12v batteries are connected in parallel to give 12v for normal running. The batteries are switched to series for 24v starting. The batteries are switched back to parallel once the engine starts.
I believe that 12v is the standard for on highway in North America. 24v is very common in other parts of the world. Series-parallel doesn't seem to be used much any more.
Some installations may have two 6v batteries instead of a 12v battery.
