10-15A is still a slow charge. Normally anything below about C/4 or C/5 is considered a slow charge, and that can run up over 25A for bigger batteries. Very low current charging relative to capacity when a battery has been deeply discharged can allow the battery to remain sulfated and shorten its life. 2A charging is never fast enough for discharged boat sized batteries other than topping off a cranking battery. Some manufacturers are recommending minimum 40A chargers for their AGM deep-cycles now.
