Enhanced Durability: The tubular design minimizes wear and tear on the positive plates, significantly reducing corrosion and degradation. This durability translates to a longer battery life, typically between 5 to 7 years, compared to the 2 to 3 years offered by flat plate batteries. Better Performance in Extreme Conditions: Tubular batteries handle high
Customer ServiceLead-acid terminal corrosion is increasingly common as batteries age. Corrosion is more likely during overcharging, or hot summer weather. Leaking electrolyte from a cracked battery case also causes corrosion. The simplest way to counter vented lead-acid battery corrosion, is to use sealed AGM or gel batteries depending on the application.

Customer ServiceLead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable. Desulfation is the process of reversing sulfation

During the past several years extremely corrosion-resistant positive grid materials have been developed for lead acid batteries. These alloys consist of a low calcium content, moderate tin content, and additions of silver. Despite the high corrosion resistance these materials present problems in battery manufacturing.
Corrosion occurs primarily on the grid, and it is known as a “softening and shedding” of the lead off the plates. This reaction cannot be avoided because the electrodes in a lead acid environment are always reactive. Lead shedding is a natural phenomenon that can be reduced but not eliminated.
Provided by the Springer Nature SharedIt content-sharing initiative The liberation of hydrogen gas and corrosion of negative plate (Pb) inside lead-acid batteries are the most serious threats on the battery performance.
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
Corrosion of plate-lugs, straps or posts of negative plates in valve-regulated batteries. This reaction will, of course, also take place under open-circuit conditions. With increasing length of the electrolyte film above the separators, the local acid concentration decreases, which tends to accelerate corrosion.
