Spiral Wound Batteries Do Suffer From Sulfation
Spiral wound batteries are AGM (Absorbed Glass Mat) batteries constructed in such a way that they can be positioned in any orientation without having to be kept upright. Despite of this structural uniqueness, the internal chemical composition is similar to any AGM battery or lead acid battery and will suffer from sulfation. Both battery types contain the same lead and lead oxide plates soaked in sulfuric acid and will eventually form an insulating sulfate crystal barrier within the battery over time.
