Lead acid battery is widely used in industry, transportation, power system, communication and other fields because of its low price of raw materials, mature technology, good safety performance and stable performance. After more than 150 years of development, all aspects of lead-acid batteries are constantly improving, and the performance has also been greatly improved. More and more lead-acid batteries with different functions appear in practical applications, such as deep cycle batteries, which are specially used in the field of regular deep cycle, and occupy an important position.

How does deep cycle battery work?

The working principle of deep cycle battery basically follows the traditional lead-acid battery. Its positive active material is lead dioxide (PbO2), the negative active material is sponge lead (Pb), and the electrolyte is dilute sulfuric acid (H2SO4). There is a water decomposition reaction in the charging process. When the positive electrode is charged to 70%, oxygen begins to precipitate, and when the negative electrode is charged to 90%, hydrogen begins to precipitate. Due to the precipitation of hydrogen and oxygen, if the gas produced by the reaction can’t be reused, the battery will lose water and dry up. When charging under the specified charging voltage, the oxygen (O2) released from the positive electrode can be transmitted to the negative plate through the partition channel surface, reduced to water.

What are the classifications of deep cycle batteries?

In order to achieve the purpose of not adding water, valve regulated lead-acid batteries with unique internal oxygen cycle reaction mechanisms are mainly used in deep cycle batteries on the market. Therefore, the classification of deep cycle batteries is similar to that of VRLA batteries.

The separator of the VRLA battery is an important part of VRLA battery. Therefore, according to the processing method of separator, deep cycle battery can be divided into three types: short fiber separator, sintered separator and skeleton separator. The battery can also be divided into plastic partition, paper partition and glass partition according to the theme material of the partition. According to the difference in usage and environment, the common lead-acid battery separators in the market are PVC, PE, PP and AGM. AGM separator is mainly used for VRLA batteries. Deep cycle batteries can also be divided into 2V, 6V, 12V deep cycle batteries by using voltage.

 

What are the advantages of deep cycle batteries?

The reason why deep cycle battery develops so rapidly and can be widely used in various fields is that it has the following advantages:

(1) The price of raw materials is 1 / 3-1 / 5 of that of Ni MH battery, Li ion battery and Ni Cd battery.

(2) The difference between the positive and negative electrode potential is large, the electromotive force is high, and the single cell voltage can exceed 2.0V.

(3) The over potential caused by polarization is small, the discharge voltage is high and stable, so it is an ideal regulated power supply.

(4) The reaction rate of oxygen evolution from the positive electrode and hydrogen evolution from the negative electrode is slow under open circuit conditions.

(5) Mature manufacturing technology, a variety of products, can produce different capacities, different sizes, different uses of batteries.

(6) It has good high and low temperature performance, and can be used in the working environment of - 40 ℃ - + 50 ℃. Although the discharge capacity is reduced at low temperature, it can still work normally.

(7) The floating charge battery has a long life and no memory effect, so it can be used as a floating charge battery.

(8) Good safety, no flammable and explosive components and components, safe to use, stable and reliable electrical performance.

(9) It is well sealed, not easy to leak, and will not produce acid mist during charging and discharging, which will lead to equipment corrosion.

(10) The recovery rate is high.

 

Due to the advantages of the performance and function of deep cycle batteries, the traditional lead-acid battery has been replaced in some fields and become a new generation of products. The batteries researched and produced by champion Power Technology Co., Ltd. sell well in domestic and foreign markets, and have been exported to more than 70 countries with a good reputation and product quality.
