Dead Battery

Is it possible you may had a problem recharging the TT while traveling? You could verify this by checking the voltage of your TT battery while connected to the TV running idle. The voltage should be over 13.5v.

Did you try charging the TT battery with the smart charger after you got home? It may be possible that the TT charger has a problem.

I did drained my battery once because of the fridge but recovered after charging via the TV after an 8 hour trip.

Good Luck....

First I would say get a voltmeter so you actually know the battery health at any given time.
Second, the battery drains from an excessive draw (unless the battery itself is defective) so you need to do some investigating as to what that draw is
Third, how long was the drive from home to CG while the fridge was in 12V mode? As mentioned above, the fridge can draw beyond the capacity of the little wires that connect your truck to your camper...

You mentioned only 4 12v items were used , a radio for 10min which is insignificant, a table light ( for how long? Incandescent lights can draw down a battery in unusually rapid time, think of a vehicles overhead light accidentally left on overnight and a dead battery the next morning), the water pump - in some water pump setups, the pump can have a habit of continuously running because it doesn't hold enough pressure to keep the pressure switch from constantly cycling, so that's something I would check, does the pump pressure up and then stay off forever until a faucet is opened and pressure is reduced? Or does the pump tend to cycle every 15, 20, 30 min trying to maintain a certain pressure? And lastly I think you indicated you switched the fridge over to propane, are you absolutely sure you did this? Both turned on the propane and turned off the 12v? As a fridge in12v can kill a battery inside a day.

Keep in mind the smoke/CO detector is a constant draw also whenever the battery is connected and the camper is open.

Thanks for your input.
Got (and use) a voltmeter. The trip was only 2 hrs. The light over the table was on for about 1 hr. before we noticed that it was getting pretty dim.

I have an appt. with the dealer's service dept. on Thursday. I figure since the rig is still under warranty, I'll let them do the head scratching. Took the battery to work at the motorcycle shop today and put it on the commercial Battery Tender. After 4 hrs., it still didn't even begin to take a charge... Will report the results of service visit.
Thanks to all for the response.

If you have a light that you use for an hour at a time- and you want to
camp off the grid- get LED bulb(s) for that fixture.
Remember back in the bad old days-- 60-70-80s? IF you left your
dome light on in your car over night it probably wouldn't start in the
morning. A single incandescent bulb draws an amazing amount of
power out of your battery. Most goes up as heat and not light.
LED is the way to go for boondocking.

you may wish to check if your breakaway cable got jammed underneath the front leveling post when you set up your trailer. I made this foolish mistake last summer, and basically what this does is pull the pin on the switch, which activates your electric brakes, which basically drains your battery ..or in my case batteries really fast. In my case it ruined two batteries .. and i had to buy a set of new ones, which are now true deep cycle heavywieghts ... not the marine batts i had before.

believe me .. i always check that cable when setting up now ... this could have been your problem ...

from viewing your last post .. its definately time to get a new battery ..

I know this thread has sort of ended but we just got back from
3 days camping off the grid.

I had a couple surprises and some insight to share-- In the 1st 24 hours-
We watched a couple hours of TV using a little cigarette socket inverter.
My little LCD TV says is uses 30 watts so it's pretty miserly.
Ran the furnace once in the morning to take the chill off.
Used LED lights sparingly.
Fridge on LP only mode.
End of day 1 I found my batteries nearly dead! Went around and checked
everything I could think of and found that stupid "environmental" switch
on my fridge ON.
My fridge has a heater built in the metal strip that separates the top freezer
from the bottom fresh food doors.
The heater warms the strip and stops condensation. The problem is
that heater runs on DC power and is a battery hog!
If you like camping off the grid be SURE and check to see if you have
a little rocker switch found hidden under the top of your freezer door frame. I thought mine was off but it obviously got bumped back to on
some time in the past. I'm either going to disconnect it or tape it or
something. We DON"T care about a little condensation between
the doors!

I'd brought my little Honda 2k so I fired it up and plugged in my trailer
AND attached a stand alone 25 amp smart charger.
I've tested this before and each one charges less when I use both but
the total is more than either one at a time.
So I use both to speed up the process.
Ran the genny about 2 hours.
Shut down back to normal.
Watched a little TV, used minimal LED lights went to bed.
Next morning ran the furnace to take off the chill and it sounded
sluggish.
Checked and batteries are almost dead again.

My 2 plain old 12v "deep cycle/crank/marine batteries are now starting their
7th season.
Just checked Sam's club and they have
Duracell® Golf Car Battery - Group Size GC2
for $85. Guess it's time to upgrade to a pair of 6 volt.
Looks like these will fit my existing battery boxes.


It's time to get out there!!
Happy Camping!

Inverters, even small ones, are really inefficient and will drain your batteries quickly. I'd look into getting a 12v television as well as replacing your dual purpose batteries with true deep cycles. The combination should make a huge difference.

You're right! I'm NOT complaining. My trailer came with a stupid 12v
and the dealer didn't want to "buy it back" so I kept it and added a 2nd
one.
They served us well for 6 years.
BTW- I know inverters are inefficient BUT I have used this one for 6 years.
In the past when my batteries were new and the stupid fridge anti-condensation switch was OFF we've camped as long as 5 days without
a genny and watched an hour or so of TV every day.
It's important to unplug the inverter when not in use!
