Sorry my shop charger is 140 amp which I ran the batteries on the 50 amps setting for 24 hours periods. The charger never indicated much over 20 amps during this cycle. I did this multiple times and could never get my batteries to test over 60% CCA even when the charger would indicate 100% charge. I could watch the voltage drop from 14 to 10 in less than 5 minutes after they would come off the charger. That is when I went to a better smart desulfating charger. With the price of AGM's I am happy that I have recovered over 14 AGM batteries. Well worth the $600 I have in chargers. I do charge the batteries first with the shop charger for 1 day and then put them on my spare Genius for 1 to 2 weeks depending on how they test.
