I have a 2003 38 Open and have 6 GEL batteries in the boat. 3 for the engines/generator and 3 for the house... I changed the original 6 batteries in 2020 (17 years) because I was concerned they would fail all of a sudden... Boat is always plugged in when docked (even when winterized)... Bought 6 new 31 GEL batteries from NAPA and to date, when load checked, are all in great shape.... Remember when changing batteries consider the charging profile of your alternators and dock chargers as the charging profile for standard wet cell bateries, GELS and AMG's are different. Need to address when changing from one type to another..
