AGM battery setpoints?
Now that I have this nice fully adjustable Rogue MPPT 3048 I suddenly realized that I don't know battery setpoints - Absorb V, Float V and Full I (charging current at SOC 100). Alright, current in...

I would charge and float at the lower end of specification.
Transition at 2 to 5 amps.
Transition to Float - I read about 1% of capacity, so it's 1A for 100 AH battery. 2-5 A = lower transition SOC, (70% ??), and my gut feeling is that this is better for battery. Might take too long to charge fully. Will see.
"Lower end of specs" - UPG table suggests 14.7 at 77F, and at the same time allows 14.4 to 15V. This is not a temperature range, but allowed range at 77F. Weird...
Though, Deka specs aren't too accurate either, in the range 70-80F it's 14.3 optimum and 14.6 max, no telling what is the "minimum" - makes me think that at 77F it should be 14.3 or less.
No, Deka's specs are exact. Page 5, Appendix A.
Charging rates are discussed in detail on Page 3.
