An additional battery for the 2019 SE premium

[Angurita]

The "low battery, start engine soon" message would appear every time I hopped in my car after my auto start/stop feature stopped functioning. Since January of 2025, I have only driven it around 13,000 miles. I figured maybe I just hadn't driven it far enough to get a charge. My transmission light is now on, though, and we've linked everything to the spare battery. We were unable to find the specified battery at either of the provided locations. Where the passenger's foot rests or beneath the cover of the windscreen wiper motor. Is anyone familiar with the precise location of this battery?

To put it simply, the 2019 Evoque did not include an auxiliary battery because they were discontinued in late 2015.

Your primary battery under the hood is the source of the warning; before you attempt to charge it, though, you should check the date stamp; if it's more than five years old, the battery is likely dead and won't hold a charge even when parked for long periods or on short trips.

The Evoque battery requires a constant 12.7 volts to power all the systems in the background, even when the car is parked and locked. If the voltage drops below that, low battery warnings will be displayed.

Much obliged. This was starting to cross my mind. A backup battery was mentioned in every single post and YouTube video we came across. Going so far as to divide 2019 into two distinct generations

The second generation L551 Evoque, an MHEV (confusingly called MY2020), was introduced in the UK in 2019. There is a 48-volt battery under the passenger seat and a 12-volt one under the hood.
