To get your boat, RV or off-grid applications running, you need deep cycle batteries. Even those who have a solar setup at home, need these batteries. While deep cycle batteries are of different types, lithium deep cycle batteries have an edge over the other forms.

Usable Energy

Lithium deep cycle batteries have almost twice the usable energy offered by acid or lead deep cycle batteries. While lead batteries cannot be completely discharged, lithium batteries can. The usable energy provided by a lithium deep cycle battery is 30 – 40% more than that of an acid or lead battery. There are no damaging effects associated with lithium deep cycle batteries either.


When choosing any kind of battery, the consumer gives a lot of importance to its weight. As compared to lead and acid deep cycle batteries, lithium deep cycle batteries are much lighter. The moderate weight of a lithium deep cycle battery contributes towards its efficiency and assures you of better mileage along with multiple performance benefits. Because of its lightweight structure, installing a lithium deep cycle battery proves to be very convenient.

Faster Charging

Nobody likes to use a battery that takes forever to charge or recharge. The charging speed of a lithium deep cycle battery is four times more than that of its lead or acid equivalent. The reason behind it is that lithium proves to be more efficient in consuming energy. Unlike lead and acid batteries, lithium batteries are not dependent on the ‘absorption phase’ to get themselves fully charged.

Shelf Life

When you invest in lithium deep cycle batteries, you can expect them to last for a long. Lithium batteries that are IEC or UL listed go up to 4000-5000 cycles. An acid or lead battery, on the other hand, offers 500 – 100 cycles. A cycle can be best described as a complete discharge and recharge of any kind of battery. 

Value for Money

Lithium deep cycle batteries tend to be more expensive than lead and acid deep cycle batteries. However, they help you save quite a bit of money in the long run. The lifespan of a lithium battery is much, much higher than acid and lead batteries. These batteries prove to be four times more long-lasting than lead and acid deep cycle batteries.


A large number of companies are manufacturing lithium deep cycle batteries and are making huge profits owing to their high demand. If you have had some bad experiences with using a lithium deep cycle battery in the past and are looking for a company you can trust, you should get in touch with Home of 12 Volt.


What is a Lithium Deep Cycle Battery?

A Lithium Deep Cycle Battery is a rechargeable battery designed to be discharged profoundly and recharged multiple times. Unlike other battery chemistries, Lithium Deep Cycle Batteries can be removed up to 80% of their capacity without damaging the battery. These batteries are commonly used in renewable energy systems, electric vehicles, and marine applications due to their high energy density, low weight, and long cycle life.

How do I maintain a Lithium Deep Cycle Battery?

Maintaining a Lithium Deep Cycle Battery is relatively simple. First, avoid discharging the battery below 20% of its capacity, as deep discharge cycles can shorten its lifespan. Second, store the battery in an excellent, dry location and avoid exposure to extreme temperatures. Third, charge the battery using a charger specifically designed for Lithium Deep Cycle Batteries, and avoid overcharging the battery. Finally, periodically check the battery's voltage and capacity to ensure it operates within its specifications.
