I took the ‘trickle charger’ approach after suffering the dead car syndrome and so far, it has not dead-car’d again for a year. (My Volvo dealer said all the staff with company cars use a trickle charger to mitigate the extra drain on the 12v battery that these new AAOS systems are creating)

Look at this company CTEK for trickle chargers. I went for the MXS 5.0 UK. It’s important to set the charger to AGM mode as the 12v batteries in the Volvo are AGM type.

The trickle charger option is good for when the car is not being driven frequently or for short durations e.g., working from home. The problem may arise however, if and when you ever have to leave the car somewhere for an extended period of time e.g., airport carpark.
