4 FAQs about Explosion-proof lead-acid battery cabinet vs lead-acid battery

Do lead-acid batteries release hydrogen gas?

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.

How does a lead-acid battery room work?

Lead-acid battery rooms require continuous mechanical ventilation moving at least 1 CFM per square foot of floor space. The system must exhaust hydrogen gas at ceiling level using explosion-proof fans. NFPA 70 mandates this to keep hydrogen concentration below 1% of the lower explosive limit (LEL).

Do flooded lead-acid batteries need ventilation?

Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building. VRLA batteries require comparatively lower ventilation, usually enough to remove heat and gases that might be generated.

What is a flooded lead-acid battery?

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.

Maintaining Compliance in the VRLA Battery Room

Introduction Battery room compliance can be interpreted differently depending on your battery type, amount of cells or multi-cell units in a common area, volume of electrolyte and voltage
