What's the 2017 Cadillac CT6 battery location?

The location of the battery is the same in the 2016, 2017, 2018, and 2019 model years of the Cadillac CT6, and it's not where You may think. Instead of being in the engine bay, You'll find it in the trunk of the car, located under the trunk carpeting and a trim panel. In order to gain access (for example, for a change), You'll need to remove a bracket and a cover. While the location isn't too inconvenient, You'll just need to remember where it is in case You need a battery replacement, or if You need to jump the car from another. It doesn't change much, but it does change the positioning of the vehicles, if You're going to have a buddy get You started.
