Equalize batteries
You can coarsely determine their state of charge by measuring their quiescent voltage -- i.e. their voltage when you haven''t tried charging or discharging them in the last few hours.. Lead-acid batteries (and, well, a lot of batteries) become less charge-efficient as they get nearer to top-of-charge. As such, if they are reasonably near, they will tend to self-balance.
A Review of Cell Equalization Methods for Lithium Ion and
Traditionally, cell-to-cell imbalances in lead-acid batteries have been solved by controlled overcharging [6,7]. Lead-acid batteries can be brought into overcharge conditions without permanent cell damage, as the excess energy is released by gassing. This gassing mechanism is the natural method for balancing a series string of lead acid battery

Equalizing is an "over voltage-over charge" performed on flooded lead-acid batteries after they have been fully charged to help eliminate acid stratification. It helps to eliminate the
Battery imbalance
Rather harsh and makes batteries to lose some water, but does the job. It also equalizes the cells within the battery. Some controllers do this once in a while, some batteries don''t like it very much. The normal imbalance for a 12v lead batteries is less than 0.5v when charged and way less (less than 0.1v) in intermediate state of charge. p.s.
