Confirmed: The Battery Genuinely Needs "Coding" After Replacement — Seat Ateca Battery
This is genuinely worth understanding before assuming a simple battery swap is the end of the job: SEAT's shared VW Group Battery Management System needs the new battery's details — capacity, chemistry, and serial number — registered to the car's Gateway module, a process usually called battery coding. Skip this, and the car's charging strategy keeps assuming the old, worn battery is still fitted, which can lead to overcharging or undercharging the new one and shortening its life prematurely.
Seat Ateca Battery: The Part Everyone Blames First, Not Always Correctly

Seat Ateca Battery: What It Does
Starting the engine and running electrical systems whenever the engine isn't turning — that's the Seat Ateca's 12V battery job. If it has stop-start, it works much harder than older designs, since the engine cuts out and restarts constantly, which is exactly why it needs a specific AGM or EFB battery rather than a standard one.
