Which Deep Cycle Batteries Are Correct for My Fire Pump?

Selecting the correct battery for your fire pump is critical for both safety and compliance. According to Australian Standards, the only approved battery for fire pump applications is a VRLA AGM battery. That is exactly what Valen Power delivers.

Why Are AGM Batteries Required?

AGM stands for Absorbent Glass Mat, which is the internal material that holds the battery acid suspended between lead plates. This advanced technology allows AGM batteries to be sealed, spill proof and maintenance free.

AGM batteries used in fire protection are typically classified as deep cycle batteries. Deep cycle means they can be discharged and recharged repeatedly, making them ideal for backup power and emergency systems like fire pumps.

These batteries are also known as VRLA batteries, meaning Valve Regulated Lead Acid. This design prevents gas build up under normal operation by safely recombining gases internally. If excess pressure builds up, it is released through a built-in safety valve.

Can I Use a Car Battery in My Fire Pump System?

We often get asked if a standard car battery can be used for a fire pump. The short answer is no.

Car batteries are designed for short bursts of power, not the continuous, reliable performance that fire pump systems demand. They are usually flooded wet cell batteries, which were banned for fire pump use due to safety hazards, including the risk of explosion.

Several years ago, one of our own technicians experienced a battery explosion on site caused by improper battery use. He was exposed to battery acid but was wearing protective gear and had access to a safety shower. This incident reminds us that choosing the correct battery is not just about compliance. It is about safety.
