In automobile repair workshops and electric vehicle after-sales service centers, the baked enamel iron pointer-type battery tester is just like an experienced “physical examination doctor”, quietly monitoring the health status of the batteries of numerous vehicles.

Xiao Zhao is a senior technician in an automobile repair shop. Every day, he has to deal with the troubleshooting and repair of various automobile failures. Among them, battery problems are relatively common. One day, an owner anxiously drove his car to the repair shop, complaining that the car responded slowly when starting, and sometimes it even took several attempts to start.

Xiao Zhao first turned his attention to the vehicle’s battery. He took out that baked enamel iron pointer-type battery tester. The baked enamel iron shell of this tester is not only sturdy and durable but also has good heat dissipation, which can maintain stable performance during long-term use. Xiao Zhao skillfully connected the positive and negative poles of the tester to the corresponding poles of the battery.

Instantly, the pointer of the tester began to swing. Xiao Zhao carefully observed the direction and swing amplitude of the pointer. He found that the value shown by the pointer on the voltage scale was slightly lower than the normal standard, and during the load test, the swing of the pointer was obviously weak. This indicated that the battery’s power storage was insufficient and its output capacity decreased under load. It might be due to the vehicle being parked unused for a long time or problems such as plate sulfation in the battery itself, which led to the decline of its performance.

Based on the indication of the pointer of the tester, Xiao Zhao had an idea in mind. He explained the condition of the battery to the owner in detail and suggested that the owner first charge and repair the battery. If the effect was not good, it might be necessary to replace it with a new one. The owner followed Xiao Zhao’s advice. After charging and repairing, Xiao Zhao used the baked enamel iron pointer-type battery tester to test the battery again. This time, the value shown by the pointer on the voltage scale returned to the normal range, and the swing of the pointer during the load test also became powerful. The vehicle started normally again. The owner sincerely thanked Xiao Zhao for his professional repair skills and that reliable battery tester.

In another scenario, Xiao Li in an electric vehicle specialty store was also using the same type of tester. A customer’s electric vehicle had a significantly shortened riding distance, and it was suspected that there was a battery failure. Xiao Li removed the battery of the electric vehicle, placed it on the workbench, and then used the baked enamel iron pointer-type battery tester to test it.

After connecting the tester, he saw that the value shown by the pointer on the current scale was low, which meant that the battery’s current output was insufficient during the discharge process. Xiao Li inferred that it might be due to changes in the concentration of the electrolyte inside the battery or poor contact in the connecting wires, which affected the current transmission.

Xiao Li checked and adjusted the electrolyte of the battery and carefully inspected the connecting wires. After finishing the treatment, he tested it again, and the current indication of the pointer returned to normal. After the customer got back the electric vehicle, he found that the riding distance had returned to its original state and praised Xiao Li and his baked enamel iron pointer-type battery tester highly.

The baked enamel iron pointer-type battery tester, with its intuitive pointer display method, enables maintenance personnel to quickly and accurately judge various performance indicators of batteries. Its sturdy baked enamel iron shell adapts to the complex working environment of the repair workshop and is not easily damaged. Whether in the field of automobiles or electric vehicles, it is quietly playing an important role, helping maintenance personnel discover battery problems in a timely manner, providing effective solutions for vehicle owners, ensuring the normal operation of vehicles, and becoming an indispensable and capable tool for vehicle battery testing.
