From my research, I found that the battery is an Exide EK151 model. This tends to retail from around 50-60 pounds on the internet but I found it online here:- If your vehicle is conventional, does not have much electronics and is of some age, it is very likely that it has a conventional acid battery.

There are slight discrepancies in the dimensions but I don't think that will matter. 2mm higher for the B14155 isn't much. Smaller dimensions will always fit in. The batteries are sent by an external courier service for which we have contracted a 24-hour delivery service that, under normal circumstances, they are complying. The terminology here described the battery used for "Start/Stop" as the TSS (twin solenoid starter) battery. The TCU battery (T2R23864) is stored internal to the TCU as shown in the picture in the thread from dernotte. It is a battery assembly with two batteries. It should last at least 10 years. The TCU is located behind the left loadspace trim panel.It can be done. The larger battery (known as the starter battery) is a 99R/T4 sized battery and the smaller, pre-model year 2021, auxiliary battery is an Exide EK151. Or you can get JLR labeled batteries. On the contrary, your vehicle is equipped with a start-stop system, there are two main technologies: AGM or EFB. Shipments to Portugal. Shipments to Portugal, on some occasions, tend to take a little more delay in shipments.

The attached document describes how to replace the small auxiliary battery in the the 2020 and before model years. I'm only jumping in because this was one of the first search results I found when searching for "Auxiliary Battery" and "Evoque" in Google - and I found other threads elsewhere talking about the Auxiliary Batter and confusing the two...

These are the small AGM batteries found in pre model year 2021 cats.Free Delivery is not available for Over-Sized parcels, such as Exhausts, Radiators & Headlamps - For details on these items please see the 'Oversized Items' section below. As the batteries can be installed with the terminals "facing" the conductor or "facing" towards the headlights, the convention is to verify the polarity of the battery by placing ourselves on the side closest to the terminals (as if we "glued" the terminals to our body) You have to be careful in the process to insulate the positive cables from everything. The DC-DC converter may activate taking power from the traction battery and making the positive cables live in an attempt to recharge the removed battery. The workshop manual gives a complete process for deactivating the 12V system in the car to safely replace the batteries. I doubt it is followed by many.
