Convert your Cayenne from lithium to a dependable AGM
Lithium main batteries can throw charging faults, drop out on cold starts, and cost far more to replace. Converting your Cayenne to a quality AGM battery restores reliable starting and start-stop performance at a fraction of the price.
The catch is the electronics: switching chemistry changes the battery type the car expects, so the charging and start-stop system must be re-coded. We fit the correct AGM to OEM specification, re-register the battery type to the ECU, preserve your ECU memory through the swap, and clear any warnings — at no extra cost.
Porsche's European Start-Stop system expects a specific battery type and needs ECU memory saving throughout the swap. A lithium-to-AGM conversion also requires the battery type to be re-coded, or the charging system mismanages the new battery. We handle all of it — so reliability and performance work from the first drive.
Cayenne conversions we cover
All generations of the Cayenne take a fitted AGM conversion with battery-type coding included. Prices are for the complete conversion — battery, fitment, lithium removal and free ECU coding.
