12.4 is say 75% SOC of 6-sixes at 225 a pair so bank is 675AH so was down by 169AH going in. Allow 35 amps for likely charging rate based on OP info.
35 amps is a 5% charging rate so would reach say 95% before Absorption starts and then if it is a Tracer it will hold at 14.6ish for two hours more before dropping to 13.6v
The Bulk is to do 169-34 = 135AH at 35 amps = almost four hours, then another two before dropping to 13.6v = almost six hours.
OP says he was at 13.7v after half an hour. So only another five and a half hours to go before it drops to Float. That would not signal the batts are truly full of course, but almost full.
