Volvo V90 (as well as V60, XC60, XC90, etc.) VOC Battery Replacement

Here is a step by step video to replace the battery for the “Volvo On Call Service Required” warning. The warning shows up if the VOC battery faults or every 8+/- years as a notice that you should replace the battery to ensure if you need emergency services etc., you’ll have it. Think of it like needing to replace the batteries in your home’s smoke detector every few years. Once completed, I understand you still need to get your Volvo dealership to do a software update to reset the battery, which I’ll be doing. Comments and questions are welcome.
