of course when you’re sitting (which is a high percentage of their cycle), you get zero mpg, unless you have the engine shutoff feature.
Then you do maintenance like UPS where you replace the starter at every oil change....
How long do the batteries last?
Starter motors could be built with enhanced bearings, gear engagement systems and become brushless....
UPS has those replaced starters rebuilt in Murrieta, CA, at my brother’s former plant (he managed it until retiring last year). You’re correct, they replace them aggressively.
