![]() ![]() The classic flooded type is simply not robust enough and on repeated cycling causes a sharp capacity fade after two years of use. Because of good performance at cold temperatures, AGM batteries are also used for marine, motor home and robotic applications.ĪGM is also making inroads into the start-stop function of cars. Being sealed, AGM reduces acid spilling in an accident, lowers the weight for the same performance and allows installation at odd angles. NASCAR and other auto racing leagues choose AGM products because they are vibration resistant.ĪGM is the preferred battery for upscale motorcycles. AGM has a sweet spot in midsize packs from 30 to 100Ah and is less suitable for large UPS system.ĪGM batteries are commonly built to size and are found in high-end vehicles to run power-hungry accessories such as heated seats, steering wheels, mirrors and windshields. ![]() The negatives are slightly lower specific energy and higher manufacturing costs than the flooded. AGM offers a depth-of-discharge of 80 percent the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life. The leading advantages of AGM are a charge that is up to five times faster than the flooded version, and the ability to deep cycle. It stands up well to low temperatures and has a low self-discharge. AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead acid type. The plates can be made flat to resemble a standard flooded lead acid pack in a rectangular case they can also be wound into a cylindrical cell.ĪGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep-cycled. This enables shipment without hazardous material restrictions. The acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. AGM technology became popular in the early 1980s as a sealed lead acid battery for military aircraft, vehicles and UPS to reduce weight and improve reliability.
