Measuring 353 × 175 × 190 mm and the positive terminal on the right, it is the direct replacement for boats fitted from the factory with a 90 Ah battery of this format.
- Sealed: no spills or gases in the locker.
- Resistant to humidity and salt air.
- Good balance of capacity, cranking power and price.
- Ready for starting outboard and inboard engines.

### Vehicles compatible with the Exide EN800

According to our database, the Exide EN800 equips more than 12 vehicles from brands such as Elan Marine, MANtra Yachts, Dufour Yachts, Saffierjachten, Nordborg-Baanordborg and Najadvarvet Ab, among others. If you are looking for a **battery for a Elan Marine** or MANtra Yachts with these dimensions, the EN800 is one of the usual replacement references. The compatibility list also includes models from Slottayachts, Etap, Hallberg-Rassy, Huntermarine, Salona Yachthandel and Corby Yachts.

### The Exide EN800: Marina Start range and conventional lead-acid technology

Within the Exide catalogue, the **Marina Start** series groups the references designed for this use. The EN800 is the 90 Ah model of that family, with the same performance as its siblings in other sizes.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

### Dimensions, polarity and mounting

It has external dimensions of 353 × 175 × 190 mm and weighs 20.10 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down and 1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### What Exide does differently

With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### How to make it last longer

As a service battery, avoid routine discharges below 50% to extend its cycle life. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

### Warranty and coverage

The Exide EN800 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Shipping, delivery and returns

Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### How is the Exide EN800 battery installed in the vehicle?

In most boats it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Exide EN800 battery last?

Expected lifespan of the Exide EN800 is 4 to 6 years in regular boat use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the measurements of the EN800 model?

Dimensions (length × width × height) are 353×175×190 mm — also written as 353x175x190 mm and correspond to the European L5 case size — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Is the EN800 valid for my vehicle?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The EN800 fits 12 verified vehicle versions in our database.

### What are the equivalents of the EN800 model?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop boats. See the "Equivalents" section to view recommended options at the same performance level.
