How long is appropriate for the second charge of a new battery?

[McLeo]

The second charge of a new battery is appropriate after waiting for the charging indicator light to turn green and then charging for an additional hour. Generally, the service life of an automotive battery is 2-3 years, while the original battery of a new car can last more than 3 years. Function of car battery: It is a device that converts chemical energy into electrical energy, belonging to a DC power source. When starting the engine, it provides a strong starting current to the starter. When the generator is overloaded, it can assist the generator in supplying power to electrical equipment. When the engine is idling, it supplies power to electrical equipment. The battery also acts as a large-capacity capacitor, protecting the car's electrical appliances. When the generator's terminal voltage is higher than the electromotive force of the lead battery, a portion of the electrical energy is converted into chemical energy and stored, which is the charging process. Car battery maintenance methods: Do not start the vehicle frequently. In winter, when the car is difficult to start, avoid continuous starting. Continuous starting of the motor will definitely cause excessive discharge and damage to the battery. The interval between restarts should be more than 5 seconds. When the battery has been in use for about two and a half years, routine maintenance should include battery testing to prevent issues. Try to avoid using electrical equipment such as CD players or cigarette lighters when the vehicle is not running, and minimize the use of various in-car electrical devices while driving. Battery working principle: The working principle is to convert chemical energy into electrical energy. The battery uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 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 discharging, metallic lead is the negative electrode, undergoing oxidation and being converted into lead sulfate; lead dioxide is the positive electrode, undergoing reduction and being converted into lead sulfate.
