How Long Does a Car Battery Last Without Driving?

The fundamental function of a vehicle battery is to convert chemical energy into electrical energy when the automobile’s ignition is turned on. The battery also powers automotive accessories such as the radio, clock, and alarm system. When the automobile is not driven, the battery has little opportunity to recharge, resulting in a dead battery. This is why consistent driving is so important.

If you leave the battery in your car while it is parked for a lengthy period of time, it will go from fully charged to entirely dead in less than two months. To recharge your vehicle’s battery, experts recommend driving it for at least 30 minutes once a week. A new automobile battery can last for around two weeks before needing to be recharged. The length of time a battery lasts while the engine is turned off is determined by how it is kept, how old it is, and how it is utilized.

Keeping Your Vehicle’s Battery Charged Even Not in Use

The easiest method to safeguard your battery is to drive it frequently. Other activities can also be taken to keep it charged when not in use. These are some examples:

  • Turn off the security system.

You can disengage your vehicle’s security system if it is parked in a safe area. Leaving the security system on will cause the battery to drain faster.

  • Remove the negative battery cable.

The negative battery terminal is positioned on the battery’s top. Disabling this wire will assist in preventing battery drain. Turn the negative connection counterclockwise to loosen it carefully. Once it’s free, remove the negative connection from the battery by pulling it off and laying it aside.

  • Remove the battery completely.

If your car will be parked for an extended length of time, it is better to remove the battery fully. Keep your batteries in a dry, well-ventilated environment with a constant temperature of 40 to 60 degrees Fahrenheit. When you remove the battery, it will naturally drain at a slower rate, therefore you will need to charge it when you replace it.


Given regular driving distances and climate control usage, car batteries should last 4 to 5 years or more. When your battery dies, recycle it to save resources used in the production of new batteries. If you discover your battery is dying, replace it with a new, high-quality battery so you can get where you need to go with confidence.
