One study found that lithium batteries might be as much as one-third lighter than their lead-acid AGM counterparts. Any boat owner should give this some thought. The weight of a 100Ah AGM deep-cycle battery may reach 38 kilograms, whereas a comparable 24V lithium marine battery can drop to around 12 kilograms! Lightening the load improves fuel economy and performance while operating in a maritime setting.

It is good knowledge that charging a lead-acid battery takes some time. Charging a lead-acid battery overnight is something everyone has done. Furthermore, there are many essential charging phases, including bulk, absorption, and float. When setting a lithium battery, a complicated sequence of steps is unnecessary. They experience less resistance from inside, allowing for a higher charge rate to be applied.

When comparing, it is essential to consider the total cost of ownership. Conduct a thorough analysis of the total cost of ownership. People who are turned off by lithium batteries because of their higher initial price often do not consider how much cheaper they are throughout their lifetime. Lead-acid batteries have a shorter useful life than lithium batteries. However, lithium batteries are less expensive.

Even though a single lithium battery has the potential to survive as long as three or four lead-acid batteries combined, the former are often changed with more regularity. Lithium batteries have a far cheaper total cost of ownership compared to other battery types. This is particularly true when the price and inconvenience of replacing your batteries every few years are considered.

The Lithium Marine Batteries

Marine lithium batteries are far lighter than lead-acid ones, which is a significant advantage for boat owners. On average, a lithium battery is around 70% lighter than a lead-acid battery pack. When steering a boat, the captain should have minimal extra weight. Sailors who keep their boats as lightweight and efficient as possible often opt for lithium batteries.

The lifespan of lithium batteries is much greater than that of regular lead-acid batteries. The lifespan of a lithium-ion battery is often ten times that of a traditional battery, meaning that a single lithium unit may replace many brand-new lead-acid batteries. A lead-acid marine battery will typically last for about 500 charge-discharge cycles. Meanwhile, a lithium-ion battery may provide boat owners up to 5,000 cycles.

Those who have ever had a boat equipped with a lead-acid battery are aware that after the battery has been reduced by around half of its capacity, the battery may start to lose power and have to be charged as soon as possible. However, lithium-ion batteries can store a far more energy and can be drained to significantly lower levels before their capacity are lost.

Generally speaking, lithium-ion batteries can save up to 80% of their capacity, and some may even be discharged to 100% without suffering any ill effects. Moreover, because of the increased storage capacity, owners may get away with installing fewer battery units and a smaller total number of batteries than they would have to use lead-acid batteries.

Conclusion

We really hope that our comprehensive guide on the maintenance of lithium marine batteries has been educational. Do not be hesitant to get in touch with the industry professionals if you have any inquiries about the maintenance of your lithium-ion boat battery or any other queries regarding lithium marine batteries.
