How Long Does It Take to Fully Charge a Dead Car Battery by Driving?
1 Answers
It takes about 3 to 4 hours of driving to fully charge a dead car battery. The functions of a car battery include: 1. Providing a strong current to the starter when starting the engine; 2. Assisting the generator in supplying power to electrical devices when the generator is overloaded; 3. Supplying power to electrical devices when the engine is idling; 4. Protecting the car's electrical appliances. The working principle of a car battery is based on the lead-acid battery, which operates on the primary cell principle. The positive plate is made of lead oxide, and the negative plate is made of pure lead. When the load is connected, the lead on the negative plate reacts with sulfuric acid to form lead sulfate and lose electrons, while the lead oxide on the positive plate reacts with sulfuric acid to form lead and water, gaining electrons, thereby generating an electric current.
