Dual battery answers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was trying to figure out for the longest time what happened if you ordered BOTH the dual battery option and the HD battery option. Was the second one also an HD battery?

I decided not, so I'm running the big Delco Cadillac battery as main and the smaller R59 as the aux.

According to the Heritage center docs:

Batteries
- TP2 Aux: 45-amp-hr, 9 plate
- T60 HD Battery: 80-amp-hr, 15 plate

There's no mention of the TP2 Aux ever being the 15 plate battery, so I think my hunch was correct.
