Tech Note | Battery Room Ventilation Requirements
Lead-Acid (LA) and Nickel Cadmium (NiCd) batteries vent hydrogen and oxygen when they are being charged. In the case of Valve-Regulated designs, the hydrogen is recombined with the oxygen within the battery back into water unless the gassing volume/pressure exceeds the opening setting of the pressure relief valve. Hence the name Valve-Regulated.

Get a quote6 FAQs about [Exhaust fan connected to lead-acid battery]
How does a lead acid motive battery work?
Lead acid motive power batteries produce hydrogen gas and other fumes at 80% recharge point, making proper ventilation in the battery charging area extremely important. Hydrogen gas is not only colorless and odorless, but is lighter than air, causing the gas to rise to the top of a building.
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.
What are the requirements for a lead-acid battery ventilation system?
The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. 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.
How does a lead-acid battery work?
In a lead-acid battery, the plates are assembled so there is always one extra negative plate. The plates are close to each other but do not touch, which would cause a short-circuit. One set of plates is connected to the negative side of a DC source, the other to the positive side.
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.
