1 Answers
To install an auxiliary battery in a sedan, follow these steps: 1. Install a battery isolator; 2. Secure the auxiliary battery next to the main battery. The usage method is as follows: 1. When charging, connect the main and auxiliary batteries in parallel for simultaneous charging; 2. When not charging, the battery isolator automatically separates the main and auxiliary batteries, ensuring the main battery does not discharge when the auxiliary battery is in use; 3. In case of main battery failure or depletion, use the emergency auxiliary switch to draw power from the auxiliary battery to start the car. The functions of a car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the car's electrical equipment when the engine is off or at low idle; 3. Providing power to electrical devices when the generator's output is insufficient.
