PT keeps asking whether AGMs will spend more time in Bulk at the same charging rate. I found a good example where that can be measured, using ah64id's test with his PD4655 on his pair of Lifeline...

Just did a test and recorded results just got done. Ran down my bank to 49% by running a/c for some of the time and fridge and a/c blower for a while then let it rest a bit, then turned on charger:
8:28 start 125a 49% 12.25v
8:53 absorb 125a 68% 13.9v
8:57 120a 72% 14.02v
9:04 99a 77% 14.05v
9:15 60a 83% 14.09v
9:32 40a 89% 14.12v

This is two Lifeline GPL-4CT's for 220ah at 12v with a Magnum 3000 hybrid 125 amp charger set to AGM1 charge profile and Magnum BMK battery monitor for SOC.
