It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
The following brief overview describes different lead-acid battery technologies and how they would interact with a ventilation system. are commonly called “flooded” or “wet cell” batteries be-cause of their conspicuous use of liquid electrolyte. As the name implies, this type of battery “vents” hydrogen continuously during normal float operation.
Vented Lead-acid Batteries are commonly called “flooded” or “wet cell” batteries. These have thick lead-based plates that are flooded in an acid electrolyte. The electrolyte during charging emits hydrogen through the vents provided in the battery. This reduces the water level and therefore periodic addition of distilled water is required.
Failure mode – a rare but serious battery failure mechanism in lead acid batteries is a condition known as “thermal runaway.” Thermal runaway is preventable. Vented (flooded) – flooded batteries are largely immune to thermal run-away, but it is not impossible.
