What is the battery model of GAC Trumpchi GS4?
2 Answers
GAC Trumpchi GS4 uses a battery from the Varta brand. The following are the functions and working principles of the battery: Functions of the battery: During engine startup, it supplies power to the starting system, ignition system, electronic fuel injection system, and other electrical equipment of the car; when the engine is stopped or at low idle, it supplies power to the car's electrical equipment; when the power demand exceeds the generator's supply capacity, the battery also participates in power supply. Working principles of the battery: The negative electrode is made of lead plates filled with sponge-like lead, and the positive electrode is made of lead plates filled with lead dioxide, with 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead is the negative electrode, undergoing oxidation and being oxidized to lead sulfate; lead dioxide is the positive electrode, undergoing reduction and being reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two electrodes respectively.
I've been driving the GAC Trumpchi GS4 for almost three years now. The original battery is a Varta brand 12V 60Ah model 55D23L, easily identifiable by its label. Once during winter, the car suddenly wouldn't start, and after checking at a repair shop, I found out the battery was dead. The mechanic tested the voltage and said it was below 12 volts, so it needed replacement. He recommended choosing the same model from a reputable brand to match the system. The GS4's battery is located under the trunk, which is easy to access, but you need to be careful about moisture as the terminals can rust easily. I clean them monthly and apply anti-corrosion spray. For daily use, avoid leaving the car parked for too long as the battery will slowly discharge. I've developed a habit of turning off the AC and lights when parking to save power, and I also keep an emergency power pack in the car just in case. When replacing the battery, it's best to go to a professional shop—incorrect installation might affect the car's computer system. The key to extending battery life is regular maintenance, which ensures both peace of mind and safety.
