Battery Choice Opinion Please UPDATE
Updated 26 April ---------- Thinking of getting one of these to replace an old pair of wet 6s, where the price here is similar to new 6s. Not sure if it is suitable for RV use doing 50-90s some...

The thing about underhood AGM's, is how many are being deeply cycled to the point they can accept huge heating amperages for a long time, and then fed alternator amperage via a voltage regulator seeking 14.4+ volts the entire time?
Very few.
Starting batteries are barely discharged at all in starting duty, and thus never can accept huge amperages from where they heat from within, and then are also subjected to engine heat.
But, I'm, done with flooded batteries. Much rather look at an ammeter and voltmeter, than dip a hydrometer, and My current AGM is going on to being the cheapest cycle per dollar, but to be fair to my previous flooded batteries, I could not truly fully charge them, as I could not control voltage precisely enough, and bring it high enough, for long enough.
Now I can, and could likely extract excellent lifespans from marine car jars.
But I wont, unless I can't afford an AGM at the time. I do not expect to be surprised with a failure though.
I want a battery which can accept everything my alternator, told to seek 14.7v can make, and laugh. I want to charge a 90Ah battery with 65 amps for 20+ minutes. I will choose an AGM which can handle what I can feed it, and laugh.
No doubt GC-2s are best bang for buck, but they are not for me, nor are they the best choice for everybody else.
