Is AGM better than gel battery?

AGM Batteries have a lower internal resistance that allows for much faster charging and better performance under heavy load conditions. AGM Batteries will most likely also perform better than GEL in colder operating conditions, and AGM is often less expensive as an option for getting reliable power.
