What Symbol Indicates a Dead Car Battery?

[SanColin]

When a car battery is dead, it will display a battery-like symbol. Here are some maintenance tips for car batteries: 1. In-car electrical usage: To maintain the car battery, avoid activities like listening to the radio loudly, charging your phone, or using an air pump when the engine is off. Prolonged use can drain the battery, and frequent depletion significantly reduces its lifespan. 2. Long-distance highway driving: Regularly driving on highways has many benefits, not only clearing carbon deposits from the vehicle but also fully charging the battery. Generally, driving on the highway for over an hour can fully charge the battery, keeping it in optimal condition. 3. Avoid prolonged vehicle inactivity: If the car is not used for an extended period, disconnect the battery cables or start the vehicle every two weeks and drive a few dozen kilometers to ensure the battery remains functional. 4. High-power electrical connections: Many car appliances, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power. Avoid powering them directly from the car battery. Instead, start the vehicle first before connecting these devices.
