The Mantra Yachts Mantra 28.0 1990 may use different batteries depending on engine and equipment. We found 5 compatible batteries priced between 132,65€ — 214,68€. Check dimensions and positive terminal position before purchasing. ### Can I install a higher capacity battery in my Mantra Yachts Mantra 28.0 1990? Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Mantra Yachts Mantra 28.0 1990 battery compartment and the positive terminal position matches. ### 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. ### 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? 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. ## Guides ### How to identify the battery polarity of the Mantra Yachts Mantra 28.0 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 Mantra Yachts Mantra 28.0 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 <strong>RIGHT</strong> → choose a battery marked as "positive right". If it is on the <strong>LEFT</strong> → 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. ## Related links - [Plate search](/buscador-de-baterias-por-matricula) - [HTML version](https://baterias.com/gb/boat-batteries/mantra-yachts/mantra/280/1990) - [llms.txt](/llms.txt) ### Other languages - [ES-ES] [https://baterias.com/baterias-para-barco/mantra-yachts/mantra/280/1990](https://baterias.com/baterias-para-barco/mantra-yachts/mantra/280/1990?format=md) - [EN-GB] [https://baterias.com/gb/boat-batteries/mantra-yachts/mantra/280/1990](https://baterias.com/gb/boat-batteries/mantra-yachts/mantra/280/1990?format=md) - [PT-PT] [https://baterias.com/pt/baterias-de-barco/mantra-yachts/mantra/280/1990](https://baterias.com/pt/baterias-de-barco/mantra-yachts/mantra/280/1990?format=md) - [FR-FR] [https://baterias.com/fr/bateaux-batteries/mantra-yachts/mantra/280/1990](https://baterias.com/fr/bateaux-batteries/mantra-yachts/mantra/280/1990?format=md) - [IT-IT] [https://baterias.com/it/batterie-per-barche/mantra-yachts/mantra/280/1990](https://baterias.com/it/batterie-per-barche/mantra-yachts/mantra/280/1990?format=md) - [DE-DE] [https://baterias.com/de/bootsbatterien/mantra-yachts/mantra/280/1990](https://baterias.com/de/bootsbatterien/mantra-yachts/mantra/280/1990?format=md)
