Today, AGM (Absorbent Glass Mat) Batteries are a mature technology that has been around for almost forty years. But did you know that in the early 1980s, it opened new horizons for battery use in aircraft and UPS?
It was launched as a lighter battery than the ubiquitous flooded lead-acid batteries and was welcomed as a more reliable battery for applications where leakage can be particularly hazardous. It is a sealed, maintenance-free battery that has lead and sulfuric acid as the main active components. A very fine fiberglass mat buffers and absorbs the sulfuric acid, which makes the battery spill-proof.
The increased safety of the new AGM batteries meant they could be shipped anywhere without fear of hazardous spillage. The isolation of the hazardous components makes AGM batteries highly suitable for use in aircraft and delicate electronic equipment. Also, its ability to produce a strong current made it highly suitable for use wherever there was a requirement for short but intense power delivery.
Today, AGM batteries are the preferred batteries for motorcycles, as they are relatively light and have a sealed casing that allows installation at various angles. AGM also contributes to rider safety as the sealed battery is less likely to spill acid in an accident.
Car and motorhome owners are also rapidly rediscovering the benefits of AGM technology. Starting a car requires significant power, which usually depletes the capacity of a conventional flooded type battery within two or three years. An AGM battery is far more robust and typically lasts far longer.
Car accessories such as electronic mirrors, windshields, and steering wheels tend to be power-hungry, which is where the leak-proof and light AGM batteries come into their own. Their resistance to vibration is an additional advantage in the transport industry. The auto racing industry, including NASCAR, provides ample proof of its robust performance.
The growing popularity of AGM batteries in transport applications is also due to their low self-discharge profile. These batteries can be stored unused for long periods before recharging becomes necessary. It is perfect for cars or boats that are only used occasionally. Owners get the benefit of a very high-powered battery combined with long-term reliability.
