What battery is everyone using

Turbostart AGM Group 27 Red Cap Mopar Restoration Battery. 4.5 years old
Battery tender connected over the winter and when not driving for long periods.
AGM is the way to go. I happen to like the Mopar vintage look too.
Group 27 instead of 24 for the additional CCA and reserve, fits easy and I'm not worried about the weight. It has been reliable and cranks my 418 stroker with ease.
In my Duramax I run 2 Blem Interstates... 2 of those cost less than one of these.
Interstate Blems in every other vehicle, boat, trailer, RV just not my Mopars...
