Optima red top is rated 800CCA at zero degrees.

Red Top is not a deep cycle, Optima Yellow tops are starting deep cycles with the Blue tops being Marine/RV deep cycle.
Y'all can go back a forth with "facts" all you want.
I'll tell you from first hand experience. Years back when I knew I need to get away from water cell batteries, I called Optima to find out which batteries to run in my '96 diesel and was told that their Yellow tops were the deep cycle for starting and that they were what was needed for my truck. I ran them the first time around, then after that and talking with several Optima enthusiast I went to the Red tops and have been running them ever since.
The Red tops actually last as long as the Yellow tops in a diesel.
It's not a matter of deep cycle or not, it's a matter of QUALITY batteries.
I may have to check into the Delcos though.
