With the year we filter between AGM Start-Stop, EFB and conventional — the manufacturer may have changed the battery spec mid-production of your Najadvarvet AB Najad.
Why the year matters for the battery of your Najadvarvet AB Najad
- 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.
Enter the year and you will see the manufacturer-recommended battery alongside compatible alternatives from market-leading brands (Varta, Tudor y Exide). Express 24h delivery.

- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Najadvarvet AB Najad 355 battery compartment and the positive terminal position matches.
- 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.
- 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.
- 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.
- 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.
- 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.

Guías
-
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.
-
Locate the battery Open the bonnet of the Najadvarvet AB Najad 355 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 "−".
-
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).
-
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.
-
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.)
-
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.
General reference guide: always consult your vehicle manufacturer's manual before following these steps, as procedures may vary or not be suitable depending on model, year and equipment. If in doubt, consult a professional. baterias.com accepts no liability for damage resulting from an incorrect procedure.
