Lithium battery

What is a lithium battery?

The extremely light, soft alkaline metal lithium is distinguished by its impressive energy density. Its high electrochemical potential makes it possible to develop high-performance batteries that offer the longest service life on the market, often around 10 years. Long reserved for the discerning public, this cutting-edge technology is now finding its way onto sailboats and boats.

Why opt for a lithium battery?

Saving space and weight

A lead-acid battery is heavier, bulkier and less powerful than a lithium battery. On average, lithium batteries are three times lighter than acid batteries. The size/capacity ratio of a portable lithium battery is unbeatable.

Better energy storage thanks to lithium

Lead-acid batteries cannot be discharged below 50% of capacity without causing damage or shortening battery life. Most lithium batteries allow a depth of discharge of around 80%. This increase in energy storage is one of the greatest advantages. This type of battery can accept much higher discharge currents than an acid battery, and the same goes for its service life. The slow-discharge marine battery therefore offers many advantages for nautical and marine activities.

Long-term savings

While lithium batteries are an investment at the outset, their lifespan is far superior to that of lead-acid batteries. They last at least three times longer than other batteries. Not to mention that you can use half as many lithium batteries as lead ones.

Lithium batteries, a safe and less polluting option

Lakes, rivers and seas could appreciate this new kind of battery. Water quality and the environment win! The alkaline in lithium is less reactive to living organisms in water than acid. The portable lithium batteries available at Comptoir Nautique are sealed, so they can withstand neither moisture nor water splashes. They are safe for nautical and marine applications. Most models incorporate a battery management system (BSM ) that detects dangerous conditions and shuts down the battery to prevent potential damage.

How do I install a lithium marine battery?

Lithium batteries often fit into the battery bank in the same way as a lead-acid battery. However, you may need additional components to complete your installation. You can install a battery monitor, upgrade your inverter or battery charger to optimize performance.

Boats equipped with lithium batteries are less polluting and more economical, so there's no reason not to equip your boat with one!
