I recently got a 2007 Jayco Eagle 325BHS.. Great rig, we love it.It has 2 brand new coach batteries (admittedly, NAPA brand, but top of the line batteries for them) andwhen they are fully charged, they will go completely dead in 4 days.. That is with the camperclosed up, and nothing on. I think the detectors are still working of course, and the AM/FM radio in the bunk house is lit up and has a clock built in even when it is 'off'.I have the camper in for service today to fix a window issue and I asked them to checkthe camper for some sort of unusual electrical draw that would cause the batteries to die so quick.. Service writer said "Well, we'll look but they all do that"My Caravan would last weeks and weeks if unused and still have lights.. So I'm havinga hard time believing a twin battery setup will go stone cold dead in 4 days.I didn't notice anything unusual when we boondocked for 6 days last month, as we ranthe generator for 2 hours each day so the batteries always seemed fine on that trip.Any thoughts on that?

Those batteries should stay up for months if there is no more than detectors and a turned off radio drawing on them. NAPA batteries are a good battery. We've used them in semi-tractors and they stand up with any thing else we've used.Does your unit have a battery disconnect switch? If not, I would consider putting one in.

If you =do= have one, use it. I admit that 4 days is a bit quick to kill 2 new batteries, though. You sure you've not got anything else on, like the fridge or furnace? Fans'll kill your batteries quickly. I learned the expensive way NOT to forget my battery disconnect.Lyle

use a disconnect switch or just disconnect the batteries and let sit for a few days and see what happens. If batteries still go dead, battery problem. If they are good start looking at the 5er.

How flat dead did you run them? Below 11.0 volts for very long could already have permanently lost capacity from sulfation.Many converters take 48+ hours for full charge and often chronically under charge the battery.Need to get them tip top 100% and disconnect from all loads for storage. Even better is 100+ watts of solar.A discharged battery is easy to freeze and destroy.

To answer your question: seems high to me.I had a similar problem with 2 new 12v batteries draining in 7 hours on a new 5er. Found out the Yeti cold weather package on the 12V side for the water pipe heat tape was drawing all the time due to no switch being installed from the factory for that side of the option. Dealer installed switch to control the heat tape on the water pipe so we now have plenty of battery storage for a recent 5 day boon docking trip using normal daily electrical for dry camping.Good luck and keep us posted.Lakeside

Turn everything off and put an ammeter on it and measure the draw.
