Valve regulated battery types

What are the different types of Valve Regulated Lead acid (VRLA) batteries?

Discover the two main types of Valve Regulated Lead Acid (VRLA) batteries: Absorbent Glass Mat (AGM) and Gel. Each type offers unique characteristics for various applications. Absorbent Glass Mat (AGM): AGM batteries utilize a fiberglass mat soaked in electrolyte between the plates.

What are the components of a VRLA battery?

Key Components of VRLA Batteries: Electrolyte Containment: In AGM batteries, a fiberglass mat holds the electrolyte, while in Gel Cell batteries, the electrolyte is thickened into a gel. Both methods prevent spills. Valve Regulation: VRLA batteries have a valve that regulates internal pressure.

Are there different types of VRLA batteries?

Yes, there are three main types of VRLA batteries, a sealed valve regulated wet cell, AGM and gel. Gel cells add silica dust to the electrolyte, forming a thick gel. These can sometimes be referred to as silicone batteries.

How do valve regulated lead acid batteries work?

Discover the working principle of Valve Regulated Lead Acid (VRLA) batteries: Basic Operation: VRLA batteries operate on the principle of electrolysis. Within the sealed battery, two lead plates immersed in a sulfuric acid solution facilitate a chemical reaction. One plate is coated with lead dioxide, while the other is made of spongy lead.

What is the difference between AGM and VRLA batteries?

AGM (absorbent glass mat) batteries feature fiberglass mesh between the battery plates which serves to contain the electrolyte and separate the plates. Both types of VRLA batteries offer advantages and disadvantages compared to flooded vented lead–acid (VLA) batteries or each other.

What is the difference between a lead-acid battery and a VRLA battery?

Traditional lead-acid batteries have a liquid electrolyte that can spill if the battery is tipped or damaged. In contrast, VRLA batteries either absorb the electrolyte into a glass mat (AGM) or turn it into a gel. This sealed design ensures that even if the battery is punctured or placed in an awkward position, it won’t leak.
