6 FAQs about [Lead-acid battery handling in the communications room]

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 lead-acid batteries used for?

Lead-acid batteries are the most widely used energy reserve for providing direct current (DC) electricity, primarily for uninterrupted power supply (UPS) equipment and emergency power system (inverters). There are two basic cell types: Vented and Recombinant Valve Regulated Lead-acid (VRLA) Batteries.

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.

What is the ventilation system for flooded lead acid & flooded Ni-Cd batteries?

1.For flooded lead acid, flooded Ni-Cd, and VRLA batteries, the ventilation system shall be design to limit the maximum concentration of hydrogen to 1% of the total volume of the room; or 2.Continuous ventilation shall be provided at a rate of not less than 1 cubic foot per second of the floor area of the room.

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.

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.
