Porsche vehicles generally use AGM batteries — in some models in unusual places such as under a seat or in the front luggage compartment — and benefit from battery registration through diagnostics.

Some models offered an optional lightweight lithium starter battery. These must be replaced with the correct part.
Electrolyte is held in glass-fibre mats between the plates. AGM batteries tolerate frequent deep cycling and high electrical loads, which is why they are fitted to many premium and start-stop vehicles with brake-energy recovery.
Replacement rule: A vehicle designed for AGM should be fitted with AGM. A flooded or EFB battery in its place is likely to wear out quickly and may trigger charging-system faults.
Read the AGM guide →Some electric and newer premium vehicles use a lithium-ion low-voltage battery for control electronics rather than a lead-acid starter battery. These are vehicle-specific parts, not general replacements.
Replacement rule: Only the manufacturer-specified part should be used. Lead-acid batteries are not a substitute unless the manufacturer documents it for that vehicle.
Read the Li-ion low-voltage guide →Generation-level information from our vehicle database. Where a field says “confirm”, it varies by engine or trim and is checked against your vehicle.
Under-seat and front-compartment batteries take more time to access and need careful refitting of covers and vents.
If your Porsche has a lithium starter battery, it must be replaced like-for-like.
In most cases, yes, including under-seat locations. We confirm the model and battery type first.
Tell us the model and year, and send a photo of the current battery if you can. We confirm the right battery before anyone sets off.
