Conventional wisdom, as taught to us by SLA battery manufacturers, says do not charge with a charger rated at over 20% of the battery. A 15ah battery should not be charged with a charger rated over 3 amps. In my ignorance, I have been using a six amp charger for 9.5ah batteries for two years. http://shop.odysseybattery.com/p/obc-6a

I did some research, found this explanation for why i have had no issues:
"So the bottom line is that it is OK to charge a sealed lead acid battery fast as long as you don't overcharge it. Modern CC-CV (constant current-constant-voltage) and multi-stage chargers can perform this function very well. They ensure that when the battery is full the applied voltage is less than the gassing voltage, and no damage can occur. Fast charging is important to the electric vehicle industry, and long battery life is essential, so a lot of the quick-charging research has been done for this application." https://www.powerstream.com/SLA-fast-charge.htm

I am not a battery manufacturer, nor a lawyer, and do not recommend that anyone use a rapid charger to charge their batteries. However, I will continue to do what I have been doing for two years.
