Everything You Need To Know About Deep Cycle Batteries

Batteries are just batteries, right? They store energy and release it as needed. Before you select the battery type, consider the purpose for which you will use it. One battery type is more suitable for your specific use than the other. Read on to learn more about how these batteries work,

Deep cycle battery and start-up battery.
The starting battery is the sprinter of the battery world. They are designed to output large amounts of power for short bursts. The focus is usually on providing the electricity needed to start something, such as an electric motor, and then running on gasoline. They are designed to discharge too much before charging, and deep discharge will damage the service life and performance of the battery. This is the type of battery you found in the car. After the motor starts, the alternator begins to charge the battery to a full charge. However, this is not the only application of batteries. Sometimes you need a battery that can power continuously for a long time, such as running an electric car.

These are the marathon runners in the deep cycle battery-battery world. They are not large power bursts in a short period of time, but provide less power, and last longer. Here, the battery is used to run the vehicle instead of gasoline. You may wonder if these two functions exist in the same unit. In short, yes, they did, and this is the so-called dual-purpose battery.

The discharge capacity of deep cycle battery.
As mentioned earlier, deep discharge of the start-up battery can damage its performance. However, deep-cycle batteries are not only designed to supply power for long periods of time, but also release more stored energy.

The amount of safe discharge you can discharge varies from battery to battery. Some batteries can handle only 45% of their energy reserves, while others can safely discharge up to 100%.

The use of deep cycle battery.
We have talked about the familiar fact that the car battery is the starting battery. So what are deep cycle batteries for? Usually, for anything that requires a continuous power supply for a long time.

Electric golf cart.
Electric floor cleaner.
Electric scissors elevator.
Electric wheelchair.
Electric scooter.
Electric forklift.
Recreational vehicle.
The motor of the tugboat on board.
Navigation equipment on board (when the main motor is inactive).
Renewable energy system

Types of deep cycle batteries.
There are also several types of deep cycle batteries. Although they perform the same function, the materials used to make batteries are different. Therefore, different types of deep cycle batteries have their own advantages and disadvantages. Let's look at the main points here.

Submerged lead acid.
Gel and AGM or valve-regulated lead acid (VRLS).

There is a great difference in capacity between lead-acid batteries and lithium batteries because they have different chemical properties in nature. The main difference is their ability relative to the discharge rate. Lithium batteries can provide up to 100% of their rated capacity, regardless of their discharge rate. The available energy provided by lead-acid batteries is significantly reduced and the discharge rate is higher. Although both battery types may lose capacity in cold weather, the performance of lithium changes far less dramatically. For example, at 0 °C, the capacity of lead-acid batteries is reduced by as much as 50%, while lithium iron phosphate batteries suffer only a 10% loss at the same temperature.
