### How to identify the battery polarity of the Jeanneau Sun Odyssey 39 Ds, 40.3

Knowing your battery polarity (positive on the right or on the left) is the most important step before buying a replacement: connecting it the wrong way can damage the electronics. 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 &quot;+&quot; and one black or &quot;−&quot;.
2. **Identify the positive terminal** — The positive terminal (+) typically has a red cap, red sticker or cover, a raised &quot;+&quot; 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 &lt;strong&gt;RIGHT&lt;/strong&gt; → choose a battery marked as &quot;positive right&quot;. If it is on the &lt;strong&gt;LEFT&lt;/strong&gt; → choose one marked as &quot;positive left&quot;. (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. &quot;A9&quot;, &quot;TK960&quot;, &quot;EA900&quot;). Search for the exact model with that reference and the identified polarity — never change polarity without consulting the vehicle manufacturer.
