Lithium ions are small and have the ability to pass via a micro-permeable separator which is found between cathode and anode. The most common combination of lithium ion battery is lithium cobalt oxide of the cathode, and at the anode, graphite is used. This combination is used in electrical boat, golf cart, power tool, UPS system and even solar system and energy storage system.

Lithium ion deep cycle battery is a rechargeable battery which has more cycles than general lithium battery. During discharge, lithium ions in the anode become ionized and then separated from the electrons. The ions move from the anode to the cathode via the electrolyte and rejoin with the separated electrons hence neutralizing electrically.

What is lithium ion deep cycle battery?

Lithium ion deep cycle battery means that the battery can fully discharge and still can work normally because it has more cycles. But if we often make other kinds of batteries deep discharge, it will do great damage to the battery itself.

The biggest feature of deep cycle batteries is that they can be discharged at a small current and can be 100% discharged. After deep discharge, the battery can be fully recovered. These batteries are extremely light weight offering many advantages like easy installation, easy transport etc. It provides more usable capacity.

These batteries charge faster. They have less internal resistance and so can accept a greater charge rate. Longer life is another key benefit of Lithium ion deep cycle battery. Although the life cycle of the battery depends on how you use it, temperatures, and many other factors. Lithium ion deep cycle battery has an average life time expectation of 2000-5000 cycles.

While the starting battery is a lithium-ion battery/lead-acid battery/nickel-metal hydride and nickel-cadmium battery specially used for vehicle, ship and aircraft starting, lighting, ignition and power supply.

Compared with the traditional battery, the capacitor of the new starter battery can work under the ambient temperature of -30℃~+60℃, and it also has fast charging, high current discharge, low internal resistance, and a cycle life of 100,000. The advantages of ultra-long life and so on.

Advantages of li-ion deep cycle battery

• No memory effect, meaning they do not require to be discharged completely before recharging.
• Lighter than other batteries since their electrodes consist of lightweight carbon and lithium.
• Produce more power since they have higher voltage and more stable.
• Long lifespan of approximately 5,000 cycles.
• A faster charging time due to their low internal resistance.
• A high usable capacity compared to other batteries.
• Low maintenance cost to ensure smooth performance.

Applications of Lithium Ion Deep Cycle Battery

1. They are used in boats since they are light, highly efficient and last longer than other batteries.
2.  They are used as power backup to safely provide power toelectronics, preventing instability caused by power loss.
3.  They are used in solar and wind power storage systems.

What is life expectancy of deep cycle lithium battery?

Some points can affect its lifespan, over-discharging, over-charging. Lithium batteries will be affected badly if they are more over-discharge or if charged at a high current below freezing temperature.

Because of above factors and fact that different batteries have different lifespans, it is difficult to tell a specific life of battery. Currently, Lithium batteries have average life expectancy of 2000-4000 cycles as compared to 400-1500 cycles of other normal batteries. Therefore, almost all Li-ion batteries are deep cycle batteries.Term ‘cycle’ shows a period of charging and discharging, as one cycle at one time indicates fully discharge and charged battery.

Why do we choose lithium ion deep cycle battery?

One of the best reason to choose lithium ion deep cycle battery is that they are
environment friendly. They are cleaner and safer for the environment. The cost of the lithium ion deep cycle battery is relatively high but they offer over 4 times the lifespan of lead acid battery and you will be able to store and discharge much more energy during the life of the lithium battery.

Mostly used lithium battery in the market is Lithium iron phosphate abbreviated as LiFePO4. These cells have more usable life, they are non-inflammable, and somewhat resistant to selfdestruction from over discharge because they have a smart and efficient battery management system built in. Other Lithium technologies used in the market are Lithium Cobalt Oxide (LiCoO2), Lithium Nickel M0anganese Cobalt Oxide (LiNiMnCoO2) and Lithium Manganese Oxide (LiMn2O4). But the most commonly used are lithium iron phosphate batteries and ternary lithium batteries.

Lithium batteries are now common in many electronics we use today, powering everything from power tools to vehicles and even medical implants. It reduces the risk of battery failure and application but reaching their intended performance outcomes.

Do you need a special charger for deep cycle lithium battery?

Yes, specific charger is needed to charge that battery. Right charger will help in charging the battery safely. There are a lot of reasons that we should use specialized charger. When the output is short-circuited, the output will be automatically stopped, and the charging will be automatically resumed after the short-circuit is removed. During charging, when the internal transformer temperature exceeds 90°C, the charger will stop output and alarm.

When the power lithium-ion battery is being charged, it is impossible for us to keep paying attention to the charging and the charging time-out will occur, but the built-in charging time-out of the supporting charger is on time. You need to select charger with the right voltage and amps. For example, a 12V charger is suitable for a 12V battery.

To select right amperes, you should see ampere hour (Ah) of battery. The ampere rating should not be higher than the ampere hour rating of the battery. If charger of too high ampere rating is used, battery can be damaged.

Most suitable temperature range for charging this battery is (20°C – 25°C) with no damage risk. Some lithium battery factories have made lithium ion battery that is equipped with heater. So, this battery can be charged below freezing point using specific charger. That’ is to say, a lithium ion battery should be matched with a lithium battery charger.

How do we maintain li-ion deep cycle battery?

1.  When the storage period of the battery system exceeds 3 months, it should be stored at a state of charge of 40-60%.
2. After 6 months of normal use of the power supply product, the following inspections should be made during the maintenance of the lithium-ion battery. If any fault is found, it should be eliminated immediately. Check whether the bolts and nuts of various fasteners are loose. Whether the connection lines between the packages are loose. Whether the various wiring harnesses are scratched, and whether there are exposed metal parts.
3. During the maintenance process, do not re-disassemble the battery in the battery pack by yourself, otherwise it will cause the performance of the battery to decline or damage the battery.

What is the difference between lithium and deep cycle battery?

Lithium battery is a rechargeable battery which consists of cells in which lithium ions travel from negative to the positive electrode through electrolyte during discharge and move back for charging. Positive electrode is made of intercalated lithium compound and negative electrode is made of graphite. Li-ion batteries contain high energy density and low self-discharge.

Lithium battery can give 100% their rated capacity irrespective of its discharge rate. This is better than other batteries, but it is recommended not to discharge completely, which is conducive to longer battery life.

What are the differences between lead acid deep cycle battery and lithium deep cycle battery?

• Nominal voltage. Lead acid has a nominal voltage of 2.0 volts, while lithium has a nominal voltage of 3.7 volts.
• Different energy density. The energy density of lithium is 80~300wh/g, but that of lead acid is 30~50wh/g.
• Cycle life. The average lead-acid is about 500 times, and the lithium-ion is more than 4000 times.
• Charging method. The lithium-ion deep cycle battery adopts the constant current and constant voltage method.
