How often should you start a car that is not in use?

[VanMatteo]

Generally, you should start a car that is not in use at least once a week. This allows the car's alternator to charge the battery, preventing battery drain due to prolonged inactivity. If a car remains unused for an extended period, the engine oil may flow back to the oil pan under its own weight, reducing lubrication between components. Additionally, prolonged inactivity can lead to battery drain. A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. Car batteries are categorized into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. The term 'battery' commonly refers to lead-acid batteries.
