## Quick description

**Exide ET1300 12V 180Ah 900A** is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.

## Why this marine battery?

- **Marine design** built for boat swell and vibration
- **Dual function** starts the engine and powers onboard services
- **Sealed and safe** maintenance-free even when the boat rolls

12*V* Voltage
180*Ah* Capacity
900*A* Cold cranking
49.70*kg* Weight

The **Exide ET1300** with conventional lead-acid technology is a marine battery with **180 Ah** and **900 A** of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. Its 513 × 223 × 223 mm and the positive terminal on the left make it the exact replacement for the 180 Ah battery fitted as standard to many boats.
- Ready for starting outboard and inboard engines.
- Good balance of capacity, cranking power and price.
- Resistant to humidity and salt air.
- Sealed: no spills or gases in the locker.

### What the Exide ET1300 is for

With 180 Ah, the Exide ET1300 covers motor and sailing boats, both for engine starting and onboard services. At the end of the season, charge it fully before winter storage. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 49.70 kg, 1 terminals and B0 hold-down.

### The Exide ET1300: Marina Dual Et range and conventional lead-acid technology

The **Marina Dual Et** is the Exide range the ET1300 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

### Dimensions, polarity and mounting

The Exide ET1300 is made in the 513 × 223 × 223 mm format and weighs 49.70 kg. The positive terminal on the left 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 B0 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.

### Why choose Exide batteries

Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Usage and maintenance tips

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

### Warranty and coverage

The Exide ET1300 comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How do I fit the ET1300 model in my boat?

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 our blog. 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 — with positive on the left 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 ET1300 battery last?

Expected lifespan of the Exide ET1300 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 ET1300 model?

Dimensions (length × width × height) are 513×223×223 mm — also written as 513x223x223 mm — 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.

### On which side is the positive of the ET1300 model?

Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Does this battery fit my boat?

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 ET1300 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Exide ET1300?

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.
