Battery Service

Testing, coding, and replacement — done right on modern European electrical systems.

Battery Service at 3A Garage

Modern Porsche and European vehicles rely on far more than a simple 12-volt battery — many require the new battery to be registered or coded to the car's onboard computer so charging, start-stop, and electrical systems function correctly.

Skipping battery registration on a car that requires it can lead to inaccurate battery state-of-charge readings, premature battery failure, and even start-stop system malfunctions. We use manufacturer-level diagnostic tools to properly register every replacement battery.

We also test the entire charging system — battery, alternator, and starter — so you know a weak battery isn’t actually a symptom of a bigger electrical issue.
