Can someone tell me what is the OEM battery on my 2023 Denali 6.2?  can see with everything mounted on top.   I think it's group size 94R  H7.   Is the OEM battery now AGM due to the auto start/stop?

 

part 2: If you put a volt meter on your battery posts with the engine off, what voltage do you get?  I get 12.2 but I thought I should get 13.1 - 13.2 with an AGM battery.

Fwiw, the charging system is managed and monitored by computer.

It adjusts charging, can turn adjust loads etc etc.   

 

This chart indicates what OEM equipment (but doesn't use standard industry coding)

2023 Upfitters docs include this info about charging and auto stop/start

AGM batteries don't give higher voltage just sitting there. It's still going to be 12.2.-12.7 for a good battery.
