2016 L405 Range Rover
 

Can any advise with certainty if there is a second battery on the 2016 Range Rover HSE. I have the Auxiliary Battery under the spare tire. Is their a Start Battery in the SUV, if so where?
Thank you.

might wanna check this out: Land Rover Owner Information

go to "Vehicle Battery"

That's not an answer to the question. I wasted hours on that guide long before I reached out to forum.

Sorry I tried to help

The main battery is under the hood, near the windshield on the passenger side. There are 4 plastic fasteners on the cover. There are jumper cables / trickle charger posts in front of the battery housing.

on a 2016 range rover, the main battery is under the spare tire and the suspension compressor, their is a voltage quality module in the trunk behind the right side carpet. this is used for start stop system. the module has a black and red heavy cable plugged into it along with another connector. that would be used in place of second battery at least in the u.s.a.
