Innovations of Lead-Acid Batteries

ingly low energy-to-volume ratio, lead-acid batteries have a high ability to supply large surge currents. In other words, they have a large power-to-weight ratio. Another serious demerit of lead-acid batteries is a rela-tively short life-time. The main reason for the deteriora-tion has been said to be the softening of the positive elec-trodes. However, we found that sulfation is the main rea

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.

Battery Room Ventilation Code Requirements

Battery room ventilation codes and standards protect workers by limiting the accumulation of hydrogen in the battery room. Hydrogen release is a normal part of the charging process, but trouble arises when the flammable gas becomes concentrated enough to create an explosion risk — which is why safety standards are vitally important.

Lead–Acid Batteries

Another variation of a lead–acid battery includes a different design feature—instead of battery with liquid electrolyte open to atmosphere a sealed battery with limited volume of electrolyte is made. The design prevents loss of electrolyte through evaporation, spillage, or gassing in the overcharge phase. Preventing electrolyte loss prolongs battery life.

6 FAQs about [Lead-acid battery air volume standard]

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 are battery room ventilation codes & standards?

What are the different types of lead acid batteries?

There are two types of lead acid batteries: vented (known as “flooded” or “wet cells”) and valve regulated batteries (VRLA, known as “sealed”). The vented cell batteries release hydrogen continuously during charging while the VRLA batteries release hydrogen only when overheated and/or overcharged.

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.
