What are some good AGM batteries?

Examples of good Absorbent Glass Mat, or AGM, batteries are products from Braille Battery, Exide Technologies and Optima Batteries. These brands carry various sizes of quality AGM batteries. However, the exact size of the required battery depends on the application.

The main advantage of AGM batteries is a more efficient and higher power output in a smaller package. These batteries have an impressive cranking amp output and can be charged faster than traditional flooded batteries. In AGM batteries, the liquid electrolyte is held in place by absorbent mats. This minimizes the potential for electrolyte spillage and gassing, which in turn extends battery life and increases performance.
