Concorde AGM batteries are not a gelled electrolyte. Loss of charge due to self-discharge is 3 to 10 times better than with conventional gelled, and 5 to 50 times less than with flooded batteries. In addition, they do not have the charge and discharge current limitations that most gelled batteries have. The Concorde is highly recommended by Trace Engineering. By comparison, Gel Cell batteries can be effectively ruined with just one sustained overcharge.
