Thank you, Coulomb. The new bateries are lead acid, not AGMs. The target voltages are taken from the 3-Step+ manual. I read the content at the link you provided. Thank you again. Is it corrct to assume that after the absorption time has expired based on the screw setting, the bateries will continue to charge below the gassing voltage and last longer? Thus on a long motoring leg, if I understood correctly, it would make sense to dial the absortion time DOWN? Assuming charging at anchor or on a 1-2 hour motoring leg, what would be a good target absorption time and how many turns of the screw starting from full-stop down (counterclockwise) would it take to get there?
