Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Porsche 911 Speedster battery compartment and the positive terminal position matches. ### What battery does the Porsche 911 Speedster need? The Porsche 911 Speedster needs a car battery with the correct capacity and cold cranking amps for its engine. Use our finder to select your engine and see the exact compatible options. ### What type of battery does my car need? You need the make, model and engine. If your car has Start-Stop (the engine switches off at traffic lights), it needs an EFB or an AGM battery, depending on what it came with: if it has an AGM, fit another AGM; if it has an EFB, another EFB or an AGM. On cars with battery management (BMW, Mercedes, VAG group…), moving from EFB to AGM requires coding the new battery. Without Start-Stop, a conventional battery is fine, or an EFB or AGM if you want a longer life. ### What is the difference between AGM, EFB and standard batteries? A conventional (lead-acid) battery is for cars without Start-Stop. An EFB is a reinforced conventional battery for basic Start-Stop. An AGM offers the highest performance and is fitted as standard on cars with advanced Start-Stop, regenerative braking or high electrical demand. Replacement rule: an AGM only with another AGM; an EFB with another EFB or an AGM; a conventional battery with any of the three. Never move down in technology. ### How do I find the right battery for my vehicle? Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp. ### What warranty do the batteries have? All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user. ### How long does it take for the battery to arrive? Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc. ### How long does delivery take? In mainland Spain delivery takes 24-48 working hours if you order before 6:00 pm (Monday to Friday) and the battery is in stock; mainland Portugal takes 1 to 4 working days, the Balearic Islands 2 to 5 working days and other EU destinations 4 to 7 working days. Batteries are shipped fully charged and ready to install. ## Related links - [Plate search](https://baterias.com/gb/battery-finder-by-plate) - [HTML version](https://baterias.com/gb/car-batteries/porsche/911-speedster-991) - [llms.txt](https://baterias.com/gb/llms.txt) ### Other languages - [ES-ES] [https://baterias.com/baterias-de-coche/porsche/911-speedster-991](https://baterias.com/baterias-de-coche/porsche/911-speedster-991?format=md) - [EN-GB] [https://baterias.com/gb/car-batteries/porsche/911-speedster-991](https://baterias.com/gb/car-batteries/porsche/911-speedster-991?format=md) - [PT-PT] [https://baterias.com/pt/baterias-de-carro/porsche/911-speedster-991](https://baterias.com/pt/baterias-de-carro/porsche/911-speedster-991?format=md) - [FR-FR] [https://baterias.com/fr/batteries-de-voiture/porsche/911-speedster-991](https://baterias.com/fr/batteries-de-voiture/porsche/911-speedster-991?format=md) - [IT-IT] [https://baterias.com/it/batterie-per-auto/porsche/911-speedster-991](https://baterias.com/it/batterie-per-auto/porsche/911-speedster-991?format=md) - [DE-DE] [https://baterias.com/de/autobatterien/porsche/911-speedster-991](https://baterias.com/de/autobatterien/porsche/911-speedster-991?format=md)
