So I'm in the market for ( 4 ) new coach batteries. The ones I have are 5 years old and not holding a charge as long as they should. I've read buy "Costco, Interstate, NAPA, Maintenance Free, Gel Filled, Water Filled" etc etc. Could I hear the Pros and Cons one more time? I don't have a problem with maintenance because I'm in that routine and that's okay!! I decided after cleaning up the white powder in the bottom of the tray ... time to replace the batts. Appreciate all the supportive input!!
