Deep cycle lithium battery refers to a rechargeable battery specifically designed to provide stable and reliable power over a long period of time, while being able to withstand repeated charging and discharging cycles. These batteries are typically used for applications that require long-lasting power, such as renewable energy storage systems, electric vehicles, recreational vehicles (RVs), marine equipment, and off grid power systems.
This article will mainly discuss marine deep cycle batteries from its definition, its charging method, charging appliances, to the best marine deep cycle batteries for you to choose.
Definition of marine deep cycle batteries
Deep cycle batteries are designed to provide stable energy and continuous power to loads in marine equipment such as navigation aids, fish detectors, driving lights, marine equipment such as refrigerators, audio and video systems, and towing motors. If you are looking for a battery that can be used for a longer period of time, then be sure to take a look at deep cycle batteries.
Why choose lithium marine deep cycle batteries
The construction of deep cycle lithium batteries involves the use of lithium iron phosphate (LiFePO ) or lithium nickel manganese cobalt oxide (NMC) chemicals. Compared with other lithium battery chemicals, these chemicals have advantages such as higher safety, longer service life, and better battery performance under harsh conditions.
Deep cycle lithium batteries can be discharged to a lower state of charge (SOC) without negatively affecting their overall lifespan or capacity.
Compared to lead-acid batteries, lithium batteries can be charged with higher current and have higher charging efficiency. This means they can charge faster. Lithium batteries have other advantages, as they do not require charging if partially discharged. Unlike lead-acid batteries, lead-acid batteries produce sulfates during partial charging, greatly reducing their performance and lifespan.
Lithium batteries are a better choice than lead-acid batteries. Some significant advantages of lithium batteries include longer shelf life, constant power, high temperature resistance, faster charging, no maintenance required, lightweight, and safe and harmless.
Overall, the main notable feature of deep cycle lithium ion batteries is their ability to provide consistent power output over a long period of time, withstand deep discharge, and withstand a large number of charge and discharge cycles while maintaining their performance and capacity. This also means that marine deep cycle batteries can be recharged after full discharge without significantly damaging battery performance.
How to charge a deep cycle marine battery
For marine battery users, how to charge their marine deep cycle batteries is a very important issue.
Steps for you to charge your marine deep cycle batteries right
Choose a suitable charger
Prioritize using chargers specifically designed for lithium batteries, especially smart marine battery charger that support constant current and constant voltage (CC/CV) modes. Ensure that the output voltage of the charger matches the standard charging voltage of the battery. For example, the standard charging voltage for a Tycorun 12V 100Ah battery is 14.6V 0.2V.
Control the temperature of the charging environment
Recommended charging temperature range: Charge between 5 C and 55 C to ensure battery performance and safety. Avoiding charging in extreme temperature environments may affect battery life and even lead to damage.
Detailed charging steps for marine deep cycle batteries
The main charging power sources can be shore power, onboard solar systems, marine generators, and mobile generators. In addition, it should be noted that marine start-up batteries cannot be used to charge marine deep cycle batteries, as marine deep cycle batteries are charged by the engine and must be charged using a dedicated charger. Here is the comparison of deep cycle vs starting battery, for you to have ae bettery understanding of why deep cycle batteries cannot be charging by starting batteries. As the AC generator of the engine is usually designed for lead-acid batteries, its voltage and charging method may not be suitable for directly charging lithium batteries.
Connect the positive pole (red) of the charger to the positive pole of the battery, and the negative pole (black) to the negative pole of the battery. Turn on the charger and start the charging process. Using an intelligent charger with automatic power-off function can automatically stop charging after the battery is fully charged, preventing overcharging. After charging is complete, turn off the charger first, and then disconnect the negative and positive connections in sequence.
LiFePO4 marine batteries can be charged through most AC generators. According to the quality of the AC generator, it should be able to be used in conjunction with LiFePO4 batteries. However, low-quality AC generators with poor voltage regulation may cause BMS to disconnect the battery. If the BMS disconnects the battery, the AC generator may be damaged. Therefore, in order to protect your LiFePO4 battery and AC generator, please make sure to use a compatible high-quality AC generator or install a voltage regulator.
How long does a marine deep cycle battery last
Factors such as weather, temperature, charging cycle, depth of discharge (DOD), discharge current, charging current, charging method, and static usage duration can all affect the lifespan of a battery and have a significant impact on its lifespan.
The lifespan of a properly maintained lithium battery is approximately three times that of a lead-acid battery used under similar conditions. The expected service life is over 10 years.
