6V deep cycle batteries
Have had som very overcast weather the last 4 days, batteries down to 82% in morning back to 95% afternoon, how long can this be don before a 100% recharge becomes essential. Frank

I would leave in in absorb mode all day if I could. But I have the kick back into bulk ar a high 13.2 anyway..
Float I have 13.6...Ill rarely see float while boondocking i'm sure.
Different energy use patterns, different controllers.
Not enough info from the OP but it sounds like his energy use is low. This is familiar to me. When controller terminates the Absorption, based on current or timer - late morning or early afternoon when it's sunny - it stays in Float all day. Minor draws would increase the current in, but it stays in Float because there is enough solar output to feed the loads and maintain V float.
When it's low overcast, it starts again bulk/MPPT every time when voltage drops below Absorb or Float - and it does drop, if there isn't enough output. I believe most controllers work like this.
