3500 Exp. house batteries?

[ReelMagic]

I'm surprised to hear you have golf cat batteries in the boat... I don't believe they were standard when the boat was delivered by Tiara.... I have a 2003 Tiara 38 Open with 6 GEL Batteries; 3 for the house and 3 for the engines/genertor.. After 17years I changed them with 6 new GEL batteries as the alternators, House and engine chargers were set up for GEL batteries... Need to find out what was provided by Tiara and what you house, engine & alternators are set for. M2C
