welcome, if they are brand new batteries its not uncommon for the cart to charge for up to 16 hours, new batteries are only about 75% and there is a proper break in procedure so as long as they are charging and charger isn,t getting hot and water isn,t gushing out of batteries don,t panic and it may stay close to 0 amps for quite some time before shutting off again normal......i,m breaking in a set myself right now and dealing with the same thing...............make sure the batteries are topped off with distilled water to 1/8 inch over lead plates and let the charger do its thing.......................
