I own a 2003 38 Open w/6 GEL batteries (3 for the house and 3 for the engines; no inverter). They served me well and after 18 trouble free years I changed them to NAPPA 31 series GEL batteries. I considered changing to AMG's but was concerned with the Charles Charing charging profile.. see attached.... Soo far so good after 2 years... M2C
