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?
