I need to replace the batteries on my "new to me" cruiser. I am awash in new info/technology. Last cruised so long ago a 7 ton boat with one battery wasn't viewed as particularly unusual.
Current house bank consists of two Trojan SCS225 along with an unidentified starter . I can replace the latter without problems but cost and availability make replacing the trojans' with something else almost essential.
The two golf cart option requires rebuilding I'd rather avoid. The Only suggestion I've had is an interstate 29 which I understand is a "combo" rather than a true deep cycle. Finally, for my purposes the SCS225 are more AH than I would use (by at least a refrig). Recommendations ?
