We've got 3 Lifeline 125AH AGM's, and the original alternator took forever to charge them (still happening with the high-output alternator).
I did talk with Nations, and their kit starts at 2006. I've seen that at other providers as well.
Thanks!

I was in on that thread and I thought it was taken care of. Have you gone down to 50%, which is of no hazard to your batteries, to see what the charge rate is there. As soon as you try guess at what your rate should be in the higher than even 65% full, you will likely be wrong. On our 440ah Lifeline setup we would charge at 180 amps, which is .4C, until not even 70% full most of the time and then it would start to taper. By 80% it was very much lower than 180 amps at well under 100 amps and by 90% dowon in the 20s amps.
Until you get a recharge from 50% so looking for around 190ah down from totally full (us the amp hours because we don't know at this point if the % SOC is accurate because of settings and getting a reset at full.
I would take them down to about 12.3v after no load resting for a few hours and then start you recharge at 1404-14.6v in absorption and look at the amps after about 5-10 minutes when initial inrush is over.
I would not invest in a second alternator until you do this test if it were mine to do.
What amps do you think you should be getting?
