Yes, I do have wet cells. In regard to not fully charging all the way through the float stage...I am guilty of that but only during our extended time away from the dock. This only amounts to a week or two a year. To have to charge batteries, either by the generator or by the engine for more time than I already do (when away from the dock) seems even more ridiculous than what I am doing now. Most of the time, the boat is at the dock with shore power and the smart charger fully charging the batteries.
I had every intention of checking the specific gravity of the cells this weekend and then went off and forgot to bring my hydrometer to the boat. For sure next weekend.
Note: This battery set is only 11 months old.
