Most of the power coming from our generator
just seems to be wasted since it takes so long to charge the batteries. Solar
isn't really a viable option in our case, since switching to lithium would cost about the same all inclusive. Then the generator will charge those up quickly.
The biggest advantage to AGMs is that will take a large charge, their appearance rate is high.
Of course along with that big generator you need some kinda of big charger
, my 660 AH bank will easily accept my 125 amp charger
and my 60 amp charger both for a significant time until they begin to taper off.
The disadvantage of AGM is of course they are less tolerant of partial SOC cycling, they want to be topped off, often.
But your selling right? I'd nurse your bank, I see buying
new batteries for the boat I'm selling to be similar to putting on new tires just to sell the car, it's money
down the drain. If you have to replace I'd go with Golf Cart batteries and leave the high buck batteries for the next boat.
