That “low battery” warning is an absolute PIA. My daughter’s XC70 does it. eg: stopped at a level crossing, may be there some minutes so switch off engine but keep radio on. After a couple of minutes the “low battery” warning pops up and the radio is switched off. She has a crash proof dog cage in the load area. It has a fan attachment powered from the load area 12v outlet to help ventilate the cage when the car is parked up with the tailgate open. But within a minute or two it is shut down by the car’s system. The only way to keep it running is to have the engine running. Sort of defeats the object of the exercise.
I am advised by others who have other makes of car that this is a common feature now. System is designed to progressively shut down various electricity consuming items to preserve the battery so that it will still start the car. That’s all well and good but in my opinion it kicks in far too early. I’ve never owned a car with this feature and never had any problems, other than when I stupidly left the parking lights on when parked up at work one day.
