### What battery does my boat or vessel need?

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.

## Guides

### How to identify the battery polarity of the Jeanneau Sun Odyssey 39 I

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 I 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 → polarity 0 (positive right). If it is on the LEFT → polarity 1 (positive left). On batteries with side terminals, the convention changes: polarity 4 (narrow-side right) and polarity 3 (narrow-side left).
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.
