Know how to extend the life of a lead acid battery and what the limits are. A battery leaves the manufacturing plant with characteristics that delivers optimal performance. Do not modify the physics of a good battery unless needed to revive a dying pack. Adding so-called "enhancement medicine" to a good battery may have negative side effects.
Sulfation and How to Prevent it | Redway Battery
Sulfation is a natural chemical process that occurs when lead-acid batteries are discharged and then left in a partially or fully discharged state for an extended period of time. Essentially, it''s the formation of lead sulfate crystals on the battery plates, which can significantly impact its performance.
Fighting Sulfation in AGMs
All lead-acid batteries will sulfate. Treating the batteries correctly helps reduce sulfation and leads to longer battery life. Unfortunately, sailboat batteries rarely get the treatment to hold off the sulfation long enough to achieve a desired cycle life. As a lead-acid battery discharges, lead sulfate forms.
