## EXIDE Marina Dual EZ: entry-level dual-purpose marine battery

The **EXIDE Marina Dual EZ** range is a flooded lead-acid (FLA) battery designed for boats that want a single battery covering both **engine starting** and **onboard service consumption**: navigation lights, fish finder, radio, portable fridge or basic electronics. It is the entry point into the EXIDE marine range for boaters who do not yet need to split starting and service into two separate batteries.

### Which boats the Dual EZ range is built for

- Small to medium motorboat (EZ450, 80 Ah).
- Cruising sailboat with moderate electrical consumption (EZ550, 95 Ah).
- Fishing boat or vessel with more onboard electronics (EZ650, 115 Ah).

### Compatibility and how to choose your Dual EZ marine battery

Check the **capacity (Ah) of the original marine battery** fitted to your boat and choose the matching or higher EZ reference: EZ450 for light loads, EZ550 for medium consumption, and EZ650 if you carry more electronics or need more autonomy at anchor.

## Frequently asked questions about EXIDE Marina Dual EZ batteries

### **What does "dual-purpose" mean for a marine battery?**

It means one single battery handles both engine starting and onboard service consumption, instead of splitting those two roles across two separate batteries. It is the simplest, most affordable solution for small and medium boats.

### **Is the Dual EZ compatible with any small boat?**

It is compatible if its Ah capacity matches or exceeds the original marine battery and respects polarity and box dimensions. The EZ450-EZ650 range covers everything from light motorboats to fishing boats with higher consumption.

### **How long does a dual-purpose marine battery like the EZ last?**

It depends on usage and discharge cycles at anchor, but being FLA it is worth periodically checking the electrolyte level to keep performance and service life up across boating seasons.
