Hello, today my V70 had to get started after the battery did not deliver enough power to the start. The friendly helper of the ADAC quickly led the cause to the frequent use of the original installed heater in combination with a lot of short distance operation. I can understand that because we often drive only 3-4 km in the city and let the heater run for 10-15 minutes before. Therefore, it is clear to me that the battery does not last forever! Ziemlic h I am therefore disappointed by the technical implementation at Volvo. Actually, the heater should have been switched off in time so that the car can still be started. However, there was at no time a corresponding indication in the display. Too bad! In the next days I will have to test the battery and the battery. Greetings, ss363
