With the accelerated development of the energy storage industry, the demand for deep cycle lithium battery applications continues to grow.
This article is about “What is deep cycle battery”. It will be discussed from the definition, reasons of choosing to deep cycle battery maintenance methods in order to help you get a full understanding of this kind of battery.
What is deep cycle battery
A deep cycle battery is a type of battery designed to be recharged through a charging cycle after discharge. This type of battery can reliably recharge even after reaching full discharge, and can perform hundreds of such charge discharge cycles, making it suitable for devices that require long-term continuous power supply. Deep cycle batteries are widely used in fields such as solar energy systems, backup power sources, camping, and car audio.
Advantages of deep cycle battery
After getting an idea of what is deep cycle battery, it is important to understand its advantages.
Deep cycle batteries are designed specifically for repeated and deep discharge. They are typically used in applications that require continuous and stable power supply, such as golf carts, forklifts, and solar energy systems.
The average lifespan of deep cycle batteries is 6 years. Longer cycle life, compared to regular batteries, supports deeper discharge and longer lifespan, but like all other batteries, deep cycle batteries will last longer if they remain at low discharge levels.
Deep cycle batteries can provide stable power supply for a long period of time and have good deep discharge performance, supporting discharge depths of 80% or even deeper. Other types of batteries discharge at high currents and can only provide a small portion of their capacity. Compared to them, deep cycle batteries discharge slowly and continuously, up to around 80% of their capacity, resulting in longer operating times without negatively affecting their overall lifespan or capacity. Scenarios where deep cycle batteries can provide long-term power supply, such as solar energy storage systems, electric vehicles, and backup power sources.
Low maintenance cost, lithium-ion batteries do not require water replenishment or balanced charging, and AGM and colloidal lead-acid batteries also require minimal maintenance, reducing labor and long-term replacement expenses, suitable for industrial and commercial applications, and minimizing later expenses, suitable for various application scenarios, including solar energy, RVs, electric vehicles, etc.
The type of deep cycle battery
The type of deep cycle battery will help you grasp a better understanding in what is deep cycle battery. Here are two common deep cycle batteries.
Lead acid deep cycle batteries are suitable for customers with limited budget but high demand.
Lithium ion deep cycle battery (LiFePO4) is a high-performance choice, suitable for long-term investment, lighter, more efficient, and longer lifespan. Applications such as RVs and lighting typically prefer lightweight lithium-ion deep cycle batteries. In addition, their fast charging speed and long lifespan make them the best choice. One limitation of lithium-ion batteries is that they are more expensive than regular deep cycle batteries.
How to choose a suitable deep cycle battery
When choosing a deep cycle battery, users need to consider factors such as battery capacity, voltage, weight, and cost.
Capacity
Refers to the amount of electrical energy that a battery can store, usually measured in ampere hours (Ah), and the appropriate capacity should be selected based on the power consumption requirements of the device.
Voltage
The common voltage specifications are 12V, 24V, and 48V, which need to be matched with the operating voltage of the equipment.
Weight
Due to the impact on portability, fixed applications can choose heavier but larger capacity batteries, while mobile devices need to balance weight and battery life.
Cost
Including initial purchase cost and long-term usage cost, although lithium batteries have a higher initial price, they have a longer lifespan and lower overall cost.
In addition, charging time is also an important factor. Lithium ion deep cycle batteries also dominate in terms of charging time. Compared to lead-acid batteries, the charging process of these batteries is easier. Lead acid batteries require multiple charging tests to fully charge, while lithium-ion batteries can be fully charged at once. Lithium ion batteries also do not require frequent maintenance.
The maintenance of deep cycle battery
The working principle of deep cycle batteries involves repeated chemical reactions to store and release electrical energy. However, frequent charging and discharging cycles will gradually reduce the capacity and lifespan of the battery, so proper use and maintenance are crucial.
Avoid complete discharge
When using deep cycle batteries, it is advisable to avoid complete discharge. When the battery level is below 20%, it should be charged to extend the battery's lifespan.
Shallow cycle mode
Try to cycle the battery between 20% and 80% to avoid frequent deep charging and discharging, which can significantly extend the battery's cycle life.
Use original charger
Using an original charger can ensure the stability of charging current and voltage, avoiding battery damage caused by voltage fluctuations. Try to avoid using fast charging, especially lithium batteries, as frequent use of fast charging can shorten lithium ion battery life.
Temperature control
In order to extend the lifespan of the battery, users need to avoid discharging for extended periods of time at extreme temperatures and ensure that the battery maintains an appropriate temperature during use and storage.
Regular maintenance
Checking the battery status is also an important measure to maintain battery performance.
