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 Mr Wizard,
Actually the Magnum can do 125 amps. It faults at 127 amps DAMHIK. My solar can do 17 amps. So the possible charging total is 142. The "real" number per jar is 27 amps--so maximum should not exceed 108. 142 would be 8.5 amps over per jar.
If I know the batteries are hungry I do "dial down" the Magnum to 108 amps.
I'm not worried about exceeding the charging rate. I'm just trying to work out where charging starts to taper, for that is the most efficient place to stop charging.

Don c/5 on your bank, is 111 amps
I don't think your in any danger of over charging
Even if you got full solar and full output from the Magnum
You would only exceed that by about 4 amps per battery
31 amps instead of 27 amps
C/5 on my bank is 135, I could get close in capability if I hook up both Vedctors the 25 & 40 and the pd9270, and IF the batteries were at 50% instead of 80%
