Hello, thank you so much for your time to read this text and maybe help me. it’s about an XC70 model 2011 AWD D5 good equipment (consumers are meant) etc. Stand heater, which is hardly used and not at all in the last months. The vehicle was built for the Swedish market and has a permanent evening light, which can not be impressed with the running engine by the switch position of the light 0, I, II. In principle no problem and over the years became a habit. – In 09/2018 a Hyperbolis 90AH starter battery was installed, seems to have been the first exchange, – In 04/2019 was carried out by technical workshop tire change, vehicle had to be taken off, – until 02/2021 no messages about battery condition were shown, – 02/2021 vehicle jumps at -12C normal and remains after approx. 15m. Several start attempts are still successful, but the car basically does not move any more and then gives me ruffled up. – 02/2021 exchange of the battery against a Varta Silver Dynamic 85AH has not been installed and rehearted on the battery. In case of the battery has already been taken a good time.
