What are AGM batteries and how do they compare versus Gel batteries?
AGM stands for “absorbed glass mat.” This means that the battery was designed with a glass mat that separates the plates (that hold the battery acid). AGM batteries are pretty common in use for off-grid cabins, solar systems, and solar-powered street lights and make up a lot of the Trojan batteries that we carry.
Gel batteries, on the other hand, have a silica-gel that separates the plates and are more robust (and costly), making them the choice for backup systems for schools, hospitals, airports and office buildings.
If you were looking for batteries for a solar system on your home or cabin, then you’re probably better off with AGM batteries. You can learn more about all of the various different types of batteries available and how to select the best one for you in our article Battery Technology Selection.
As a note, not all AGM and Gel batteries are made the same and are not all considered Deep-Cycle, which is the type of batteries that we carry from Trojan.
