I saw a few posts where folks are able to stay on the hook up to two days and still have power to fire up. I ask this because I have 4 group 27s - two stbd, two port. The 4 batteries of each side are wired in parallel in two banks. Two on the port were replaced two seasons ago. The stbd bank was replaced this season before splash. We stayed on the hook this weekend and when we got up Sunday morning the boat was dead. I have a jump box onboard so after some screwing around was able to get the hatch up and mains running. The other weird thing is the port side batteries appear to run the generator which is on the stbd side based on where I could get cranking power when connecting the jump box.
I don't have anything "extra" on the boat using 12v. All lights have been converted to LED. I do have the cabin fridge and the cockpit fridge. I will admit that I did not turn off the 12v side for fridges before going to bed. Would that be enough to draw down the batteries in that amount of time? That's about 13hrs with just the fridges running. It was mentioned to me that I should get a lot more time out of them. If I'm smoking something thinking they shold last longer, I'm ok hearing that too.
I was also thinking maybe I have something else drawing down the batteries but when looking at the analog amp meter they are sitting at 0amps (that I can tell). Someone also mentioned that maybe the charger isn't putting out what it should - but from the volt meter in the cabin it's showing it's putting out about 13.5-14v. I have not verified with a DVM yet.
any ideas??
