EXIDE MARINE AND LEISURE LI-Ion

Marine LiFePO4: more cycles, less weight, more usable energy

The EXIDE Marine and Leisure Li-Ion range uses LiFePO4 chemistry (lithium iron phosphate), the safest and longest-lived lithium type: over 4,000 cycles at 80% depth of discharge, far beyond any lead-acid house battery. The internal BMS supervises the battery at all times, and the weight saving is felt on a sailboat as much as in a motorhome.

EXIDE Marine Li-Ion models

• EL50-12 Li (50 Ah) — compact lithium battery for RIBs, day boats and campervans with moderate loads.
• EL100-12 Li (100 Ah) — the most versatile format as a house battery for a sailboat, motorboat or motorhome.
• EL200-12 Li (200 Ah) — a large energy bank for living aboard, long stays at anchor or off-grid campervan trips.

How to choose your marine lithium battery

Work out your daily consumption in Ah and remember that lithium lets you use almost all the rated capacity, so you often need fewer Ah than with lead-acid. Our battery comparator lets you compare the three Li-Ion models with the GEL and AGM series by capacity, weight and dimensions.

Frequently asked questions about EXIDE Marine Li-Ion

How long does a lithium boat battery last?

The EXIDE Marine Li-Ion range is rated for over 4,000 cycles at 80% discharge: with daily use all season long, that means many more years of service than any equivalent lead-acid battery.

What does the internal BMS do?

The BMS (battery management system) protects the cells against overcharge, over-discharge, short circuit and out-of-range temperatures, and balances the cells on every charge. It is built in as standard — nothing external to install.

Can I replace my lead-acid battery with a 12V LiFePO4?

In many cases yes: these are 12V batteries designed as a direct replacement. Just check that your onboard charger, alternator or solar regulator offers a lithium charging profile.

Can it start the engine?

This range is aimed at house and leisure power (fridge, electronics, lighting, camper equipment), not at cranking. For engine starting, EXIDE offers the Marina Start and Marina Start AGM series.
