I must admit that I have had NO battery issues with my new 358. Longest day on the hook was about 5-6 hours with radio going the whole time, Cockpit fridge running and cabin fridge running. DC volts got down to about 11 at the lowest point. I would think that if I was going to spend the night I would probably run the genny for the AC and this would automatically charge the batteries. Anyway once I fired up the engines and headed back I checked the dc volts after about 20 min and I was at 13volts, fully charged.
On another matter, has anyone seen rusting around any of your stainless fittings? I have orange rust colored stains around my enging compartment hinges on the swim platform. I am also noticing the same thing around some of the snaps and around the mount for the aft vertical support for the camper top.
Yes, I've seen rusting around the engine hatch hinges. Cheap screws apparently. On my list of things to replace. Oh, go around and check the screws on the ladder lid and the platform storage lockers. Again, cheap screws, as they seem to strip out. I'm seeing more than half of them need replacing. Fortunately a local hardware store has decent prices on screws and such. Given that I need a whole slew of them I may look into finding them online.
I'm not saying you're wrong, but I find it pretty hard to believe your battery "recharged" in that short of a time. I found mine took at least 2 hours with the genset running to bring it back up to full capacity. But then my "experience" with the recharging is limited, after 3 weekends of that nonsense I got fed up and just added more capacity rather than play a no-win juggling act for power consumption. If I wanted that nonsense I'd get a danged sailboat. Other boaters I know just run their genset constantly instead.
If you let the system battery go lower than 12v you'll have trouble running the chartplotter. At least, in my experience, the E-80 really starts acting up if the power dips below 12v. If you're not opening the fridges then they won't be running their usual amount and killing the battery. My typical time period for battery issues was after about 9 hours. That's getting underway on the boat around 10am for about an hour underway, and by 7 pm having trouble on the chartplotter and noting the battery drop. I'm sure that also affects recharge time. It might be that the 5-6 hour discharge time has a much shorter recovery time that my typical 7-9 hours.
But after adding the two 6v batteries in series I've never had issues over the course of whole weekends.
