Between 72.95 € and 160.45 €, VAT included, depending on capacity and technology (lead-acid, AGM). Start-Stop versions (AGM or EFB) sit at the top of the range because they withstand many more cycles.
By the registration year: 911 Speedster III (2018-2020); 911 Speedster II (2010-2011); 911 Speedster I (1992-1994). 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 Ah and more cold-cranking amps do not harm the Porsche 911-Speedster: the alternator charges it just the same and you gain margin in winter. Never go below the original values.

How to know which battery your Porsche 911-Speedster 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.

One last check: the label on the fitted battery gives you the reference capacity and cold cranking. Match or improve those numbers, and make sure the case size and polarity suit your battery tray.

Start-Stop: which battery your 911-Speedster needs

Start-Stop on the modern 911-Speedster 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.
