What battery does a Porsche Cayenne 2018 and before use?

Porsche Cayenne models built up to 2018 use AGM (Absorbent Glass Mat) batteries. These are stop/start compatible and do not require coding after replacement.

What battery does a Porsche Cayenne 2019-on use?

2019-on Porsche Cayenne models often use LiFePO₄ (Lithium Iron Phosphate) batteries. These require coding and a BMS reset after installation to ensure correct charging and stop/start operation.

Do I need coding when replacing a Porsche Cayenne battery?

For Cayenne 2018 and before, no coding is required when replacing the AGM battery. For 2019-on models with LiFePO₄ batteries, coding and BMS reset are required so the ECU recognises the new battery.

Will I lose settings when my Porsche battery is replaced?

No, we use a memory-safe voltage supply during replacement to preserve settings such as radio presets, windows, and system preferences.

How long does a Porsche Cayenne battery replacement take?

On-site replacement usually takes 60–90 minutes including diagnostics, installation, and coding (for 2019-on models).
