Several factors contribute to the bulging and explosion of lead acid batteries. Below, we detail the primary causes: Blocked Air Vents. Blocked air vents prevent the release of gases produced during charging. This blockage leads to increased internal pressure, causing the battery casing to bulge and potentially explode.
Vented lead acid batteries or flooded batteries, as they are also commonly known, consist of plates that are flooded in an acid electrolyte. When charging, the electrolyte emits hydrogen through the vents in the battery. Under normal operations, the release of hydrogen is relatively small, but this is elevated during heavy recharge periods.
