How are AGM Monobloc batteries constructed?

AGM monobloc batteries are a type of Valve Regulated Lead Acid (VRLA) battery. VRLA batteries are sometimes also referred to as Sealed Lead Acid (SLA).

Like all VRLA batteries, AGM monobloc batteries come in a standard ABS battery casing, and the lead-acid inside is formed into positive and negative lead plates. There are valves which sit at the top above the battery to release gas as the battery pressure increases.

In AGM batteries, the positive and negative plates are separated by an AGM (Absorbent Glass Mat) comprising of glass fibres which immobilise the battery’s acid and prevents it from flowing freely inside the battery.

The plates are tightly compressed into each cell and held under pressure in the plastic case. The internal compression limits are shedding of plate material caused by cycling and allows for significantly longer life. The compression also lowers internal resistance and maximises pulse power output.

What are the benefits of using AGM Monobloc batteries?

AGM batteries are rugged, easy to use, have relatively low self-discharge and are mostly maintenance-free. AGM batteries, because of their construction, can charge and discharge relatively quickly, providing excellent power output. They can be placed on a constant float charge and drawn on in emergencies or if there is a lack of alternative energy source.

In some applications, an

AGM battery can serve as a reservoir of power-saving long runs of thicker cable while at the same time, providing power in a mains failure scenario.

A further advantage of AGM monobloc batteries compared to traditional wet cell batteries is that because the plates and separator are packed tightly in their plastic cases, AGM batteries have good vibration resistance.
