New Coach Batteries
It is about time to change batteries in the coach. I have the standard two 12-volt system, which I think I will stay with. But I am considering going to AGM batteries. When we camp, we usually ha...

The definition of careful
I've not tried this with Bird's Nest Soup, brand batteries. Or Telecomm. But left on for days, in 100-degree weather, the Lifeline gained around 4.5 degrees F.
Higher than recommended float voltage over time, lots of time, accelerates plate erosion so NO it is not good for the longevity of ANY battery. Flooded, AGM, Gel, Alkaline, Lithium.
But this ain't like Baked Alaska, where a slight error ruins the dessert. And 14.4 volts will kill a flooded battery much faster than an AGM. Three or four extra unneeded hours at 14.4 volts for a thousand times may render an AGM devoid of .010" positive plate material. The battery still would have an infintely longer usable lifespan than it will living in an underchaged state.
Let's say we DOLBLE the plate thickness
Ring any bells?
The manufacturer who refuse to reveal plate thickness does it for a reason and that reason isn't pretty.
"And how many karats is the gold in this solid gold 5000 dollar watch?"
"Enough"
But then I squeeze pesos so tight I make the Aztec fart...
