How Long Should You Let a Sitting Vehicle Run to Keep the Battery Charged?
If you rarely drive your vehicle, you may be wondering how long you should let it run to keep the battery charged. While there is no definitive answer that applies to all vehicles, here are some guidelines to help you out:
- New vehicles: For new vehicles with modern batteries, running the engine for 15-20 minutes every week should be sufficient to keep the battery charged.
- Older vehicles: Older vehicles with less efficient batteries may need to run for longer periods, up to 30-45 minutes every week.
- Extreme weather conditions: In extreme cold or heat, batteries can lose their charge more quickly. In these conditions, you may need to run the engine for longer periods, such as 30-60 minutes every week.
Additional Tips:
- Avoid using battery-draining accessories, such as lights, radios, or heating/cooling systems, while the engine is running.
- If possible, store your vehicle in a climate-controlled environment to minimize temperature extremes.
- If you have a battery tender or trickle charger, you can connect it to the battery to keep it charged without running the engine.
