How Often Should You Start a Car That's Not in Use?

[Connor]

It is recommended to start a car that has been parked for about a week. Here are some battery maintenance tips: 1. In-car power usage: To maintain your car battery, avoid activities like listening to the radio loudly, charging your phone, or using an air pump while the engine is off. Prolonged use of these devices can drain the battery, and frequent depletion significantly reduces its lifespan. 2. Long-distance highway driving: Regularly driving on the highway has many benefits. It not only helps remove carbon deposits from the engine but also fully charges the battery. Generally, driving on the highway for over an hour can fully charge the battery, keeping it in optimal condition. 3. Avoid prolonged inactivity: If the car is not used for an extended period, disconnect the battery or start the vehicle every two weeks and drive it for several dozen kilometers to ensure the battery remains functional. 4. High-power device connection: Many car accessories, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power demands. Avoid connecting them directly to the car battery. Instead, start the engine first before using these devices.
