Deep Cycle Battery Recommendation
I have a GMC Tioga. Bought a new PD 9260 Converter/Charger. I want to get two 100A/H batteries. First: Dual Purpose? Or straight Deep Cycle? I know I want ASM/Sealed. What do you all recommend? Presen...

AGMs like LifeLine do not have the super high CCA ratings of Northstar or Odyssey AGM's, but the ratings are still quite high.
The ability to frequently and fully charge an AGM is paramount for its lifespan. It still takes hours to top charge them to full, but most AGMS can accept higher amps in bulk. But since you have a PD9260, any two batteries depleted could max that unit out.
I am impressed with my group 27 Northstar AGM. 930CCA, 90AH. When I take 45 AH from it at a rate higher than it established that 90AH capacity rating, voltage rebounds to over 12.2v, leading me to believe this battery is underrated in capacity.
It will be 2 years old next month, and have about 200 deep Cycles on it. Right now at ~ 180 deep cycles, It still rebounds to over 12.2v with 45AH removed from it, and can still easily start my engine depleted to below 50%.
My opinion is Lifeline make the best deep cycle AGM. I'd have no issues using one as a Starting/ dual purpose battery.
AGMS really do not like patial state of charge cycling, so you might have to press that button on the Pendant to hold 14.4v for another 4 hours.
Full charge is when amps taper to 0.5% of capacity at 14.4v at 77F. Recharge to here every cycle and it will be the best battery you ever owned.
Treat it like a red headed step child and it will become a very effective paperweight just as quickly as the cheapest AGM available in the same usage
