battery drain (dead)

new 2012 sabre 31 rets6, used 1 time and battery completely dead. battery brand is interstate. the battery sticker on top shows a date of 5/12, im assuming thats the date of manufacture. this camper is less than 1 month old, and my wife and i were careful to unplug/shut down anything that wasnt going to be needed (i.e radios, clocks, fridge, lights etc.)

wanted to go camping this weekend, and by that i mean leave in the morning. all info is in the camper as far as paperwork goes. dealer is closed and am wondering if anybody has any ideas of what kind of parasitic loss could be taking place?

why isnt a batttery shut off offered as standard equiptment or at least as an option? didnt know it was dead until i hit the landing gear retract button to hook up. aggravating as all get out.

as far as warrenty, since i cant get to my paperwork, is this going to be a forest river or interstate problem?

Numerous parasitic draws i.e. co monitor. Just plug it into your tv, retract the jacks and go camping. Shore power will charge it up when you get to the campground. When you get home again, just pull a cable on the battery or install a disconnect.

you will have to pull battery and charge with a battery charger.
the converter may not charge it up from dead .

there are few draws on your camper while sitting not plugged in such as dunnnc has said.

some newer units are coming with battery disconnects installed but not all.

you can also leave your camper plugged in when not camping if you can .

I leave mine plugged in 24/7 365

radio clock draws
co detector draws
propane detector

pulling fuses will not help as detectors are hard wired to battery .

either disconnect batteries , install a battery disconnect or leave plugged in .

At the least, your entertainment system, propane detector and CO detector will all be drawing current. The fridge control board and AC/heat thermostat might also.

A normal healthy battery will be dead in a little over a week if not connected to a charger. Normal parasite load (about an amp) will deplete a fully charged 75 AH battery in about 250 hours.

Even with just internal resistance (using a battery disconnect), a fully charged battery will "self discharge" in 3 - 4 weeks.

Just put that battery on a battery charger for 24 hours and it should be good as new. It can take 3-5 days using the converter to fully charge a depleted battery to "full."

Don't think he'll have to pull the battery. If the tv being hooked up will let him retract the jacks, the tv will start the charging of the battery and when he gets to the campground, he can just plug in a charger without removing the battery. Converter should pick it up tho'.

If its a wfco it'll prolly kill it !
They have a hard enough time not imploding at normal charging !
I'm not saying it wont work but if it was mine and truly my opinion id take it out and charge it at no more than 6 amps an hour 2 would be best .

wfco is the onboard converter/charger that would charge your battery whiole plugged in .

tv will take FOREVER to charge you battery .

If the battery is truly dead; the converter will be "off line" and will not come online until the battery recovers to at least 6 volts via an external charger.

Using the TV alternator may very well hurt his battery due to excessive charge rates (see attached PDF on Single Stage chargers - Alternators).
