battery issues on new TT

My wife and I bought a new Forest River TT from the dealer last month, and I'm having issues with the battery draining. Even with nothing on and the TT sitting in the driveway. The battery goes from fully charged, to only showing 1/3 charged ( according to the meter on the TT control Panel). The battery shows a manufacture date of 9/18, and everything is turned off. I realize there might be a very low trickle of power to the dormant stereo and control panel but that should be it. I figure either the battery is **** or there is some sort of wiring panel causing a drain on the battery. Does anyone have any tips for how to test for either one? The battery on my pop up would last for days when using the heater, lights, and pump,

    The little 3 or 4 light "battery meter" is pretty much worthless. It will almost never show full unless you are plugged in so consider 2/3 to be full with no shore power charging going on.
    Even with "nothing" on you are probably powering: refrigerator control board, LP leak detector, CO detector, TV antenna amplifier, stereo memory circuit.
    I suspect nothing is really "wrong".


    +1 This newbie killed the battery on our 2019 the first weekend just playing with stuff in the driveway. :o Took about 1.5 days and dead. It's all the little things that drain it.

    Your Propane detector is always on unless you use your built in battery disconnect or disconnect a battery cable manually.

    If you don't have a battery disconnect just take the negative cable off and nothing will get power. Some of the new switches still allow the co detector to power up along with jacks etc. Pull cable and no drain. Then install a switch that shuts off everything.

    this is how our current TT was wired when we bought it.

    TheY all have power draining. When you go to hook up cables you will see a small spark. That is power draw.

    Welcome to the forums!

    Consider adding a modest solar panel charging system. Your batteries will thank you with a much longer life span.

    The TT may have been sitting at the dealer lot with the battery hooked up. If the battery drained enough over time it could have killed the battery life. Deep cycle batteries should never be allowed to go below 12 volts.

    As others have said the "parasitic" drains can add up and can easily amount to 1 amp on newer units. This amounts to 24 amp hours per day. A group 27 battery fully charged has about 80 amp hours.

    Glad I'm not the only one! I did it twice before I realized what was happening.

    The last two TT I've had would kill the battery in a few days. Solution: install a battery isolator. Problem solved.
