Enter the registration year so we filter correctly among the variants Jeanneau may have used across production years of this engine. Last step: enter the registration year With the year we filter between AGM Start-Stop, EFB and conventional — the manufacturer may have changed the battery spec mid-production of your Jeanneau Sun Odyssey. Why the year matters for the battery of your Jeanneau Sun Odyssey Manufacturers change battery spec mid-production of a model. 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.

Estimated time: 2 minutes. Tools: eyes only — no tools required. 1. **Locate the battery** — Open the bonnet of the Jeanneau Sun Odyssey 39 DS, 40.3 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 - [Jeanneau Sun Odyssey](/gb/boat-batteries/jeanneau/sun-odyssey) - [Hanse Yachten Hanse](/gb/boat-batteries/hanse-yachten/hanse) - [Delphia Yachts Delphia](/gb/boat-batteries/delphia-yachts/delphia) - [Etap Etap](/gb/boat-batteries/etap/etap) - [Dufour Yachts Dufour](/gb/boat-batteries/dufour-yachts/dufour) - [Bavaria Yachtbau GmbH Bavaria](/gb/boat-batteries/bavaria-yachtbau-gmbh/bavaria) - [Corby Yachts Corby](/gb/boat-batteries/corby-yachts/corby) - [Dehler Dehler](/gb/boat-batteries/dehler/dehler) ## Related links - [Plate search](/buscador-de-baterias-por-matricula) - [HTML version](https://baterias.com/gb/boat-batteries/jeanneau/sun-odyssey/39-ds-403) - [llms.txt](/llms.txt) ### Other languages - [ES-ES] [https://baterias.com/baterias-para-barco/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/baterias-para-barco/jeanneau/sun-odyssey/39-ds-403?format=md) - [EN-GB] [https://baterias.com/gb/boat-batteries/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/gb/boat-batteries/jeanneau/sun-odyssey/39-ds-403?format=md) - [PT-PT] [https://baterias.com/pt/baterias-de-barco/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/pt/baterias-de-barco/jeanneau/sun-odyssey/39-ds-403?format=md) - [FR-FR] [https://baterias.com/fr/bateaux-batteries/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/fr/bateaux-batteries/jeanneau/sun-odyssey/39-ds-403?format=md) - [IT-IT] [https://baterias.com/it/batterie-per-barche/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/it/batterie-per-barche/jeanneau/sun-odyssey/39-ds-403?format=md) - [DE-DE] [https://baterias.com/de/bootsbatterien/jeanneau/sun-odyssey/39-ds-403](https://baterias.com/de/bootsbatterien/jeanneau/sun-odyssey/39-ds-403?format=md)
