    Volvo 2016 , VNL .

    Yesterday I unplugged my refrigerator and turned off the air conditioner and did not use any Devices connected to electricity during my sleep, and after five hours I was surprised by a beep coming from the sleeper/hater Control panel ,and when I wanted to turn on the Truck, it did not work? Because the batteries lost all charge? ,. The question now is why the batteries lost all charge even though I did not use any electrical conductors ?

    also when I turn the AC on when I sleep , it disconnects after a-few minutes and all Devices shut downs like my refrigerator for example ?

    can someone please explain where is the problem?
    Is there something wrong with the batteries?

    I had a 2019 LT that behaved the same way. You've got a bad set of batteries. One or two are holding somewhat of a charge but can't maintain it. Those are all issues with low voltage.

    Either the batteries are bad or you have dirty or loose connections. Check all.

    If they are lead acid, get a load checker on them. Voltage is not enough. A battery can hold voltage but not a load.

    If they are AGM batteries, bring them to a place like Loves. They have a little thing they can stick on them and it will tell you if they are bad or not. And it's free.
     
    Rideandrepair Thanks this.
