What car batteries are typically made by automotive battery suppliers？

In recent years, as automotive battery suppliers have transformed towards electrification and intelligence, the global market size of stop start battery have continued to grow. In 2023, the global automotive lead-acid battery market was valued at US$13.3 billion and is expected to maintain a high growth rate in the next few years.

Stop and start battery, as an important technology for energy saving and emission reduction in automobiles, has an increasingly prominent market potential. Start-stop batteries can provide power support when the car starts and stops, effectively reducing fuel consumption and emissions. At present, automobile start-stop batteries are mainly lead-acid batteries, which can be divided into EFB battery and AGM battery. Start-stop battery can also be further subdivided into traditional batteries, maintenance-free batteries, etc.

Currently on the market about 70% of the newly listed vehicles are equipped with start-stop technology; German cars Mercedes-Benz, BMW, Audi full-system equipped with start-stop technology, the use of AGM start-stop car battery; Japanese cars such as Mazda full-system (Atlas, Encore Sierra, cx4, cx5), Toyota (HANLANDA, CROWN, Camry, Corolla Twin Engine, RAV4) equipped with automatic start-stop, the use of more than the EFB start-stop car battery.

JYC Battery is a company specializing in the manufacture and sale of lead-acid and lithium batteries for various applications. The company has manufacturing plants in China and Malaysia and exports its products to more than 110 countries worldwide. Its product portfolio includes start-stop automotive batteries, maintenance-free batteries, motorcycle batteries, VRLA batteries, lithium batteries and energy storage systems. As one of the major global automotive battery suppliers, what kind of automotive batteries does it produce？

Working principle of start-stop battery

Ordinary car: After the engine is ignited, the car battery is always charging.

Start-stop car: When the car stops temporarily (such as when waiting for a traffic light), the engine will automatically shut down when the brake is stepped on deeply. At this moment, the high-performance start-stop battery provides power for all electrical devices in the car. When the brake is released or the accelerator is stepped on, the start-stop battery is responsible for high-power discharge to start the engine. When the start-stop battery is working, the purpose of reducing automobile exhaust emissions is achieved.

AGM start-stop car battery

AGM start-stop car battery refers to a battery with ultra-fine glass wool material used for the partition. Its structure is different from that of traditional lead-acid batteries. It is a lean battery with a small amount of electrolyte and all of it is adsorbed in the glass fiber. There is no flowing electrolyte inside the battery. It is precisely because of this unique structure that the interior of the AGM battery is more stable and the charging and discharging process is more balanced. Compared with traditional batteries, its cycle charging capacity is 3 times higher and has a longer service life. It has higher capacity stability throughout the entire service life (about five years) and is more reliable at low temperatures. And because the electrolyte is 100% sealed, there will be no gas leakage during the operation, which is safer and less harmful to the environment. Even if a collision occurs, there will be no acid leakage.

EFB start-stop car battery

EFB battery is a flooded enhanced start-stop battery, which is developed on the basis of ordinary lead-acid batteries. It can be regarded as an upgraded version of the traditional lead-acid battery. Except for the solid components such as plates and baffles, the remaining space is filled with electrolytes and can withstand high temperatures. This is why it is called a “flooded battery.”

Compared with traditional maintenance-free batteries, EFB batteries have been strengthened in many details so that they can repeatedly release strong currents in a short time and can also stably endure charging currents that are much larger than traditional batteries so that they can become a start-stop battery.

MF maintenance-free car battery

MF maintenance-free car battery adopts an advanced valve sealing design in structure, which makes the battery almost maintenance-free during use. Compared with traditional lead-acid battery factory, MF maintenance-free battery manufacturers use low antimony alloy or Pb-Ca alloy as the grid frame of the electrode plate, which increases the overpotential of positive electrode oxygen and negative electrode hydrogen evolution and reduces water loss, thus ensuring that the battery does not need to be replenished during its entire service life.

In terms of performance, MF maintenance-free car batteries have excellent starting current, anti-overcharge ability and storage time. These characteristics enable MF maintenance-free batteries to provide stable and reliable power support during car starting, driving and parking.

However, in order to extend the service life of the battery, car owners still need to regularly check the color of the electrolyte in the battery, keep the battery surface clean, and rinse with hot water in time when solid oxides are found on the electrode. In addition, during the use of the battery, car owners should avoid over-discharge and long-term non-charging to ensure the performance and life of the battery.

Truck battery

The truck battery, designed to meet the power needs of the vehicle when it is stationary for a long time, is a high-performance, long standby and easy-to-maintain energy storage device. It can not only provide continuous power support for the vehicle’s anti-theft system, remote start, car audio and navigation system, but also power the vehicle’s starting system in an emergency to ensure that the vehicle can start smoothly.

Marine battery

Marine batteries are high-performance energy storage devices designed for marine and water navigation applications. They not only meet the needs of stable and lasting power in daily ship operations but also adapt to the unique challenges of the water environment, such as humidity, vibration and changing load conditions.

Marine batteries have excellent waterproof and moisture-proof performance. The outer shell is made of corrosion-resistant materials, which can effectively resist seawater erosion and salt spray corrosion, ensuring stable operation in severe weather and long-term offshore operations. Its design also takes into account the space limitations of the ship, providing a compact and lightweight structure for easy installation and layout, while ensuring sufficient energy density to meet the diverse power needs from small yachts to large cargo ships.

Motorcycle Battery

Maintenance-free motorcycle battery refers to batteries that do not require maintenance or only require a small amount of maintenance to function normally. Unlike open batteries, this battery does not need to be replenished with liquid and water. The electrolyte is immersed in the separator between the cathodes. Even if the battery is tilted, the electrolyte will not flow out. Maintenance-free motorcycle batteries are very suitable for long-distance riding or applications in harsh environmental conditions due to their excellent performance, long life, safety and reliability, and simple maintenance.

Auxiliary battery

Auxiliary battery refers to a storage battery specially used in automobiles. Its function is to supply power to the starter, ignition system and other major electrical equipment when the engine is started, and to supply power to various electrical equipment when the engine is not running or running at a low speed. When there is too much electrical equipment and the power consumption exceeds the power supply capacity of the generator, the auxiliary battery can also assist the generator in supplying power to various electrical equipment. It is equivalent to a large capacitor, which can absorb instantaneous overvoltage in the circuit, stabilize the voltage, and protect electrical equipment.
