How often should a car be started if not driven?

[LaNicole]

A car that has been parked for one to two months without being driven needs to be started. Below are some methods for maintaining the car battery: 1. In-car electricity usage: To maintain the car battery, avoid listening to the radio loudly, charging your phone, or using an air pump when the engine is off. Doing so for extended periods can easily drain the battery, and frequent battery drainage will significantly reduce its lifespan. 2. Long-distance highway driving: Regularly driving on highways not only helps remove carbon deposits from the vehicle but also fully charges the battery. Generally, driving on the highway for more than an hour will fully charge the car battery, keeping it in optimal condition. 3. Avoid prolonged inactivity: If the car is not used for an extended period, the battery cable should be disconnected, or the vehicle should be started and driven for several dozen kilometers every two weeks to ensure the battery remains functional. 4. High-power electrical connections: Many car appliances nowadays, such as car refrigerators, vacuum cleaners, and air pumps, have very high instantaneous power. Avoid directly powering these devices with the car battery. Instead, start the vehicle first and then connect the electrical appliances.
