The article say:
"" "full charge is reached when the current decreases to 3–5 percent of the Ah rating. A battery with high
My new victron 110ah, is daily discharged with 15/ 20% DOD(12.6 open circuit voltage).
After various charging tests with different absorption times, these are the results :
absorb 2A at the ond of 1hr of absorbtion at 14.4v. After, the current drop to 0.8/ 1A at the beginning of floating at 13.8v. And after 4hr of floating decrease at 0.4 A.
If I try to extend the absorption time to 3hr (maximum allowed by my mppt controller), the current does not decrease less than 1.5 / 2 A. In my opinion it means that it is fully charged with 1 hr of absorption, and with 3 hr I am overcharging it by generating only gas. Other than that, I measured the open circuit voltage after 24 hours of recharging, and it is 13.14v. Both with 1 hour of absorption, both With 2 hours of absorption, and with 3 hours of absorption. What should I do?
