What is AGM battery technology?

Valve-regulated lead-acid batteries offer many advantages. They are easy to use, require minimal maintenance and will work regardless of how they are positioned. This has made VRLA batteries the go-to choice for a wide range of battery applications – especially those based on AGM battery technology. But what is so special about AGM battery technology?

AGM battery technology was first developed in the 1970s; the AGM stands for Absorbed Glass Mat, which refers to the way the batteries are constructed. Instead of simply flooding the battery or using gel to stabilize the acids in the cells, the electrolytes in AGM batteries are absorbed and immobilized by fiberglass mats between the plates. This means reactions between acids and the plates can happen more quickly, which allows for higher currents during charging and discharging.

The unique benefits of AGM battery technology

AGM battery technology delivers power faster and in a smaller, safer package. Thanks to their smart design, the batteries are almost never affected by vibrations. This means they can be used in more demanding environments without failing or breaking down, which has led to widespread adoption of AGM battery technology in industrial applications.

AGM battery features

The basic principles behind AGM battery technology also ensure that the internal resistance remains low – on the order of 3-5%. Combined with the fact that the self-discharge on these batteries is often between 2 and 50 times lower than that of conventional batteries, it is easy to see how the AGM VRLA battery has changed the playing field.
