An identical engine can fit AGM Start-Stop in one version and conventional in an earlier one. Amp-hours (Ah) and cold-cranking amps (CCA) also vary between years of manufacture. Fitting the wrong battery can cause electronic faults, dashboard warnings and abnormal alternator load — on cars with BMS, registering it via OBD after the swap is required.

Boats need marine batteries that are resistant to moisture and salt corrosion. Deep-cycle AGM batteries are the most recommended because they can withstand repeated discharges and recharges without deteriorating. ### What is a deep cycle battery? A deep-cycle battery is designed to be discharged to 80% of its capacity and recharged repeatedly. It is ideal for boats where it is used as an extended power source. Do not confuse it with a standard starter battery. ### 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? As they are consumable items, car batteries have a 2-year warranty, truck batteries a 1-year warranty, and all others (motorcycle batteries, cyclic batteries, etc.) a 6-month warranty. 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?

Estimated time: 2 minutes. Tools: eyes only — no tools required. 1. **Locate the battery** — Open the bonnet of the Delphia Yachts Delphia 40.0 and find the battery. It is usually a rectangular block with two metal terminals (large screw heads) on top — one red or "+" and one black or "−". 2. **Identify the positive terminal** — The positive terminal (+) typically has a red cap, red sticker or cover, a raised "+" symbol on the casing, and/or a slightly larger diameter (19 mm vs 17 mm of the negative, in standard European batteries). 3. **Face the battery** — Look at the battery from the label side with the terminals near you — the edge with the terminals should face you, not the back. 4. **Determine polarity** — If the positive pole is on the RIGHT → choose a battery marked as "positive right". If it is on the LEFT → choose one marked as "positive left". (If the label of your current or new battery shows codes like 0, 1, 3 or 4: 0 and 4 are positive right; 1 and 3, positive left — 3 and 4 correspond to batteries with terminals on the narrow side.) 5. **Note the reference** — The label on top shows the reference (e.g. "A9", "TK960", "EA900"). Search for the exact model with that reference and the identified polarity — never change polarity without consulting the vehicle manufacturer. ## Other vehicles using this battery - [Delphia Yachts Delphia](/gb/boat-batteries/delphia-yachts/delphia) - [Jeanneau Sun Odyssey](/gb/boat-batteries/jeanneau/sun-odyssey) - [Elan Marine Elan](/gb/boat-batteries/elan-marine/elan) - [Dufour Yachts Dufour](/gb/boat-batteries/dufour-yachts/dufour) - [Bavaria Yachtbau GmbH 38 Cruiser](/gb/boat-batteries/bavaria-yachtbau-gmbh/38-cruiser) - [Corby Yachts Corby](/gb/boat-batteries/corby-yachts/corby) - [Dehler Dehler](/gb/boat-batteries/dehler/dehler) - [Nicanders CB](/gb/boat-batteries/nicanders/cb) ## Related links - [Plate search](/buscador-de-baterias-por-matricula) - [HTML version](https://baterias.com/gb/boat-batteries/delphia-yachts/delphia/400) - [llms.txt](/llms.txt) ### Other languages - [ES-ES] [https://baterias.com/baterias-para-barco/delphia-yachts/delphia/400](https://baterias.com/baterias-para-barco/delphia-yachts/delphia/400?format=md) - [EN-GB] [https://baterias.com/gb/boat-batteries/delphia-yachts/delphia/400](https://baterias.com/gb/boat-batteries/delphia-yachts/delphia/400?format=md) - [PT-PT] [https://baterias.com/pt/baterias-de-barco/delphia-yachts/delphia/400](https://baterias.com/pt/baterias-de-barco/delphia-yachts/delphia/400?format=md) - [FR-FR] [https://baterias.com/fr/bateaux-batteries/delphia-yachts/delphia/400](https://baterias.com/fr/bateaux-batteries/delphia-yachts/delphia/400?format=md) - [IT-IT] [https://baterias.com/it/batterie-per-barche/delphia-yachts/delphia/400](https://baterias.com/it/batterie-per-barche/delphia-yachts/delphia/400?format=md) - [DE-DE] [https://baterias.com/de/bootsbatterien/delphia-yachts/delphia/400](https://baterias.com/de/bootsbatterien/delphia-yachts/delphia/400?format=md)
