Between 45.10 € and 169.95 €, VAT included, depending on capacity and technology (lead-acid, AGM, EFB). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: 911 Convertible VI (2019-2025); 911 VII (2018-2025); 911 Speedster III (2018-2020); 911 Targa VI (2014-2019); 911 Convertible V (2012-2020); 911 VI (2011-2020). If your year falls in the overlap between two generations, tell them apart by body type (hatchback, estate or coupé) or use the plate finder, which settles it with no doubt.
Yes, as long as the dimensions fit the tray and the terminal layout matches. More capacity (Ah) and more cold cranking (A) do not harm the vehicle: the alternator charges it the same and you gain margin in winter. What you must never do is go below the original figures.
Between 4 and 6 years in normal use. Start-Stop batteries (AGM/EFB) tend to last slightly less in city driving because of the number of starts, but they are designed for that cycling. If the car sits unused for weeks or you notice slow cranking in the cold, get it checked.

How to know which battery your PORSCHE 911 takes

The real shortcut is your registration number. It settles generation, engine and factory battery in seconds — exactly where most people get it wrong when buying.

Prefer to do it manually? Check the date of first registration on your V5C and match it against the generation table above. When a year straddles two generations, the body style decides it: five-door hatch, estate or coupé.

As a final check, look at the battery currently fitted: the label shows capacity (Ah) and cold cranking amps (A). Always replace with equal or higher figures, never lower, and keep the same dimensions and terminal layout.

Start-Stop: which battery your 911 needs

Start-Stop on the modern 911 changes the rules: the battery takes hundreds of micro-cycles daily. The correct answer is EFB for basic systems and AGM where braking energy is recovered. Dropping to a conventional battery is the most expensive mistake you can make here.
