For other AGM
batteries such as Odyssey AGM TPPL batteries it is 0.001C10 or 8 hours. According to their manual if I am reading it right.
This would mean 0.80A for an 800Ah bank.
However the implication is that if the 0.001C10 is not met after 8 hours you are not fully charged.
I presume that would occur much later during the Float mode's trickle charge?
Note that when programming a battery charger typically you set a minimum Bulk time and and a maximum Absorption time.
This creates a dilemma since once charged to Float (or at any time in the process) if you disconnect the charger and reconnect it, the charging
process starts over from the beginning.
And if you have a charger that does not sense charging current, and can only rely on a Absorption timer, the fully charged battery will hold at Absorption voltage for the full timer value. In the Oyssey case, that is 8 hours.
Picture a glitching shore power
supply while you are away for a month that has your battery bank continually at the high Absorption voltage.
Is this detrimentally overcharging the battery? Ask your manufacturer I guess.
