When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely. Just because a lead acid battery can no longer power a
Equalizing will convert water in electrolyte to hydrogen and oxygen that will escape. This results in lower electrolyte level and higher acid concentration (higher specific gravity). Problem with sealed case is you cannot replace loss water. Higher acid concentration supercharges lead-acid battery but reduces its lifespan.

$begingroup$ Correct, lead-acid is much more tolerant of ''trickle charging'' (Lithium rechargeables aren''t, their SoA is way more constrained), and if you have the opportunity to (a) full charge, and then (b) do an ''equalisation'' charge to bring up the lower-SoC outliers, then sure. But you can''t operate in a partial SoC (see-saw-ing SoC up & down) for very long before
