Are diesels harder on batteries?

Diesel trucks tend to have very high compression engines, which are harder to get started, than a typical gasoline-powered engine. That means more cranking amps are a good thing and two batteries in parallel can provide that extra cranking power.

How many volts does a diesel battery need to start?

With twin batteries providing the amperage, they’re usually enough to start a diesel in virtually any climate. Interestingly enough, a “12-volt battery” isn’t really 12 volts — it should test at 12.8 volts or more when fully charged.
