acceptance charging rate AGM batteries
Hi all, It is generally thought that acceptance rate for a flooded deep cycle battery is about 12.5 amps per 100 amp-hours of capacity once the bank is at 85% state of charge. I know that accept...

Hi BFL13,
Your posts are always stimulating. I'm going to ramble now.
My maximum charging rate is 27 amps per jar i.e. 108 over all.
I've only seen that rate once when boondocking via generator charging. I had deliberately run a total load of 1000 watts for 4 hours.
I did see it in June when it was extremely hot and I had "forced" the load support into voltage support mode and was drawing 64 amps from the battery bank.
I get about 17 amps at solar noon when the battery bank is hungry.
I'm back to blacktop camping because it is not too hot during the day and not too cold at night. (high of 26 (79 f) today and a low of 14 c (57 F))
I'm using 3 amps and the solar is providing 7.9 amps @ 14.5 volts.
The float light on the Blue Sky 3024 is flashing and I'm well under the 1% that Mex suggested is 100% state of charge.
I'm really not used to generator charging.
Another way to ask my question may be "At what percentage state of charge the acceptance rate of a surplus acid AGM reach 12.5 amps per 100 amp-hours of storage?"
Since I have 556 amp hours, that would be 69.5 amps.
So far, I've hardly ever seen that rate of charge, but I've also been a "power pole princess" since June.
Forgive me for "thinking out loud".
