Can You Start the Engine While Charging a Car Battery?

[DiCharlie]

You can start the engine while charging a car battery. Precautions for battery charging include: 1. In cold weather, check if the electrolyte is frozen before charging; do not charge a frozen battery. 2. Before charging, check the electrolyte level; do not charge if the electrolyte is insufficient. 3. During charging, measure the density and voltage of the electrolyte approximately every hour and monitor its temperature. The functions of the battery are: 1. To supply power to the starting system, ignition system, electronic fuel injection system, and car's electrical systems when starting the engine. 2. To provide power to the car's electrical equipment when the engine is off or at low idle. 3. The car battery acts as a voltage stabilizer for the entire electrical system. 4. The car battery stores excess electricity generated by the alternator.
