corrosion is another factor that greatly influences the life of a battery.
but again, there is something about the name, that makes things confusing.
corrosion is a chemical reaction to store electricity. is really oxidization of the positive plate grid surface.
but applying 2.37 v per cell (14.22 v for 12 v battery) charges satisfactorily the battery, and at this voltage, real corrosion is barely noticeable.

conclusions:
Battery industry sources are unanimous when they say that on average, 30% of automobile-type batteries end up sulfated. and sulfation, they always point out, is caused by neglect.
On the other hand, desulfation product makers insist it is the other way around, and sulfation naturally builds up in batteries over time (but many can only vaguely discuss how batteries work). They describe corrosion as more of an incidental mechanical defect, and usually treat batteries by charging the affected batteries, followed by pulsing in one form or another. This is simply modified, boosted equalization charging called by another name.
Sulfation is a term that came into use during the early days of the lead-acid battery. The meaning of the word has expanded to imply authority to include and justify every conceivable reason for the eventual performance deterioration and failure of lead-acid batteries. However.......
Lead-acid batteries that receive the best possible care, are brought to full state-of-charge regularly, consistently last the longest
(eventually wear outas result of the effects of positive grid corrosion).
Lead-acid batteries that, for a large variety of different reasons, are consistently undercharged, are not brought to full state-of-charge regularly fail prematurelyas result of the effects of sulfation.
