I posted a battery question on an early thread but didn’t explain it right. I have a 2004 280 Sundancer. My port battery went bad. I replaced it with the same type, a flooded lead acid 1050 CCA from West Marine. There are three batteries total. Two 1050 CCA, one on the starboard side and one on the port side, which is the one I replaced. The house battery is a 840. There’s a dual battery switch and a separate house battery switch. Mostly everything I have read says to replace all the batteries at the same time. Is it ok to have a different size battery for the house battery? And what size battery should I use for the house battery?
