## Description

**Exide Marina Dual EP batteries** (Endurance Plus) are the top flooded (FLA) range of **dual purpose marine batteries** from Exide: one battery that cranks the engine and powers your on-board equipment. With capacities from 75 to 140 Ah and cranking currents of 600 to 900 A (CCA), they cover everything from powerful outboards to cruisers loaded with electronics.
It is the right **boat battery** when you want strong starting power plus reserve for the fridge, fishfinder, GPS or anchor lights: a starting and house battery for your boat without fitting two separate batteries.

## Exide Marina Dual EP: starting and house power in one marine battery

The **Exide Marina Dual EP** (Endurance Plus) series combines the cranking punch of a starter battery with the energy reserve of a house battery in a single **dual purpose marine battery**. Its flooded lead-acid (FLA) construction is reinforced for the marine environment, handling vibration and moderate discharge cycles, with 600 to 900 A (CCA) for demanding inboard and outboard engines.

### Models in the Marina Dual EP series

- **Exide ER350** — 80 Ah, 600 A (CCA): small craft and outboard motors.
- **Exide ER450** — 95 Ah, 700 A (CCA): speedboats and RIBs with fishfinder and GPS.
- **Exide ER550** — 115 Ah, 800 A (CCA): sailing yachts and day boats with higher on-board consumption.
- **Exide ER650** — 140 Ah, 900 A (CCA): the largest capacity, for cruisers with fridge, windlass and full electronics.

### How to choose your EP boat battery

Pick the capacity (Ah) to match your on-board loads and make sure the CCA meets or exceeds the engine maker's minimum. You can compare all four models by size, capacity and price in our [battery comparator](/gb/comparator).

## Frequently asked questions about the Exide Marina Dual EP

### **What is the difference between the Exide Marina Dual EP and the ER?**

The EP (Endurance Plus) sits above the ER within Exide's flooded dual purpose ranges: it delivers more cranking power (up to 900 A CCA) and capacities up to 140 Ah, aimed at boats carrying more electronics.

### **Can a Marina Dual EP work as my only battery for starting and house loads?**

Yes. It is a dual purpose battery: it starts the engine and powers lights, fishfinder, GPS or a fridge without installing two separate batteries, which is ideal on boats with limited space.

### **Which EP model do I need for an outboard motor?**

For a mid-power outboard the ER350 (80 Ah, 600 A CCA) is usually enough; with heavy electronics or a larger engine, step up to the ER450 or ER550 for extra cranking and reserve margin.
