Is it "normal" for IP67 12 v @25A on 225Ah AGM battery to require 5-6 hours charge time regardless of the Depth of Discharge?
17% DoD vs 32% DoD are all taking 5-6+ hours to fully charge
In the app chart to get to float mode:
Charge contributes 36.6 Ah in 5 hours and 57 minutes
Yet, charge contributes 74 Ah in 6 hours 28 minutes
(similar time for every DoD scenario)
I checked advance settings and absorption mode is set to "adaptive". New Batteries (6v x 2, in series) AGM, (had them load tested and great), battery manufacturer settings used in advanced settings. I have also test on default high settings with same results.
Really tough to use when campgrounds (no shore avail) only allow 2 hours, twice a day to run generators. Are smart chargers not the choice to use for this type of regular RV use type which depends on limited generator time?
Any advice or knowledge to share is very very welcomed.
