currently running a century marine pro 720 (720cca 100ah) in my ute running a 80l waeco 24/7 and have a supercharge allrounder of similar spec in my gq, both seem good so far

Optima yellow top D31, 900cca and 75Ah

Can these be used as a starter battery as well?

I usually run a marine style so I can run a fridge or crank/ winch .

I’ve been successfully running 2 optima yellowtops as starters (24v) in my bus for several years, paralleled to a pair of Fullriver batteries via a VSR.

My AUX is a Trojan 115ah wet cell with a water kit.
more bang for your buck $$$, These are the same batteries
they use on the buoys out in the shipping lanes of Port Phillip bay
Never had a drama with it to date and its been 3 years since being fitted.
When its time to replace I'll be buying the same battery

[Clunk]

Same as Ova50

2 Fullriver AGMs, one 100 ah, the other 105 ah, starter is a 760 cca jobbie. The 100 ah has been in the truck (engine bay) for 6 years and still going strong, the 105 is two years old and lives in the back of the wagon away from the engine heat and hopefully will run for a lot more years yet.

The AGMs run two fridges and the comms gear.
