Basically in a nutshell, discharge AGMs BELOW 50% DOD and you WILL be replacing them (some AGMs are designed for STANDBY usage and will not tolerate being discharge more than 20% DOD). For BEST life (and capacity) AGMs should not be discharged below 20% DOD (that is considerable LESS capacity than FLA).
Can be used for more than 260 cycles at 100% discharge in
cycle service

The local Lifeline distributor quoted me $323 plus tax this morning, so hope to find a battery more reasonable. I would guess freight from CA is outrageous.

I previously had a Lifeline AGM. When it went bad, I replaced it with a $200 Universal AGM Battery. That was with free shipping. I have had the Universal for a couple of years. I went to the Universal, only due to cost.
I ran numerous test on my Lifeline, discharging and charging. You can only fully discharge any battery so many times. I have not subjected my Universal battery to the same treatment.
The following are claims made by Lifeline:
LIFELINE RV BATTERY BENEFITS
User Safe
sealed construction
non-spillable
install in any position if properly supported.
submersible without damage
Maintenance free (no adding water or repairing corroded terminals)
Fastest recharge. (no current limitations with voltage regulated recharging)
Deep Cycle (thick positive plates to provide real deep cycle performance)
Outstanding cranking performance (aircraft cell construction lowers internal resistance)
Best charge retention (especially against flooded cell types)
Lowest discharge rates (Less that 3 percent per month unattended)
For me, not needing maintenance alone is worth the extra expense. With a good three stage charger the other points are a bonus. I think most of the claims are transferable to other AGM batteries. So far, they appear to be with the Universal Battery.
I do not think this is true; "... since you will be able to make use of lower cost flooded wet cells which are able to withstand deeper discharges than a AGM." I would have to see something that supports the statement.

a little better than the typical 12 volt group 27, but nothing to get excited about.

What resources do you base this on?
Trojan lists 2 group 27's. The 20 hour rates are 105 and 115 amp hours.
Trojan group 27 battery 20 hour amp hour ratings
Their 117 Ah 100 hour rate battery is still 105 at the 20 hour rate.
