Make your car battery last longer by understanding surprising factors that affect its lifespan. Did you see the recent story on Channel 7 about car batteries draining overnight when key fobs are left nearby? Apparently, those fobs constantly search for a connection with the car—even when it’s off—which can drain your battery up to 20 times faster!
Keeping your car’s battery healthy is more important than ever these days, with all the new gadgets and shorter trips we take. Unlike the good old days where the biggest worry was forgetting the headlights, modern cars require a little extra thought.
Make Your Car Battery Last Longer: Simple Tips to Avoid a Dead Battery Surprise
Want to make your car battery last longer and steer clear of inconvenient breakdowns? These easy, practical tips can help you extend the life of your battery and save money in the long run.
1. Beat the Short Trip Blues
Starting your car draws a lot of power from the battery, and short trips don’t give it enough time to recharge. To make your car battery last longer, take it for a longer drive (at least 30 minutes) once a week to keep it charged.
2. Power Down After Parking
Phone chargers, USB devices, and other accessories continue to draw power even when your car is off. To make your car battery last longer, unplug these devices after you park to prevent unnecessary drainage.
3. Dash Cam Dilemma
Dash cams with parking mode are useful—but in a busy area like a garage, they can drain your battery fast. Disable parking mode or use an alternate power source if possible. It’s a small adjustment that can really make your car battery last longer.
4. Clean is Key
Corrosion on battery terminals can prevent proper charging. Ask your mechanic to clean the terminals and check for tight connections during your next service. A clean connection helps make your car battery last longer and improves performance.
5. Upgrade Savvy
Aftermarket electronics like sound systems or LED lighting increase power demand. Have a professional install them to prevent loose connections or overloads. A proper setup ensures these upgrades don’t shorten your battery’s life.
6. Watch the Weather
Extreme heat can accelerate battery wear. When possible, park in shaded or covered areas to make your car battery last longer, especially during hot summer months.
By following these tips, you can ensure your car battery lasts longer and avoid unexpected breakdowns. Remember, a little preventative care goes a long way!
