I have a 2019 Volvo XC60 T6 Inscription and am planning to replace the auxiliary support battery (at 25% currently). The dealer wants $319, while a new battery costs $115 plus my time.
It seems to be a quick and simple process. I read several blogs on how to replace the battery - just swap out the batteries. However, I also watched videos which said I have to also disconnect the main battery and wait 20 minutes before I install the replacement auxiliary support battery to allow the vehicle's computer to reset.
What is the correct methodology? Thanks.
