As the summer sun blazes and temperatures soar, many drivers are eager to hit the road for vacations and adventures. However, the heat can take a toll on your vehicle's battery, leading to unexpected breakdowns and frustration. Understanding the importance of battery health during the summer months is crucial for ensuring your vehicle remains reliable and ready-to-go.


Why Summer Heat Affects Car Batteries


High temperatures can significantly impact the performance and lifespan of your car's battery. Unlike the cold, which slows down chemical reactions within a battery, heat accelerates these reactions, causing the battery fluid to evaporate more quickly. This evaporation can lead to a decrease in the battery’s capacity and effectiveness. Moreover, heat can also exacerbate corrosion on battery terminals, leading to poor electrical connections.


Signs of a Failing Battery


Before your battery leaves you stranded, watch out for these telltale signs of trouble:


  • Slow Engine Crank: If your engine takes longer than usual to start, it might be time to check your battery.
  • Dim Lights: Dimming headlights or interior lights can indicate a weak battery.
  • Warning Light: A battery warning light on your dashboard is a clear sign to have your battery checked immediately.
  • Swollen Battery Case: Heat can cause the battery case to swell, which is a sign that your battery is on its last legs.


What to Do if Your Vehicle Won't Start


Finding yourself with a dead battery is inconvenient, but knowing what to do can save you time and stress:


  1. Check for Corrosion: Inspect your battery terminals for corrosion. Cleaning them with a mixture of baking soda and water might restore contact and help start your vehicle.
  2. Jump Start: Use jumper cables and another vehicle to jump-start your car. Ensure both vehicles are off and connect the cables in the correct order to avoid damage.
  3. Call for Assistance: If a jump start doesn’t work, it’s best to call for roadside assistance. Bob & Sons Automotive can help coordinate a tow to our shop, or have your vehicle towed directly to us! 


Tips to Maintain Your Battery's Health


Proper maintenance can extend the life of your vehicle’s battery, especially during the hot summer months:


  • Regular Inspections: Have your battery and electrical system checked regularly by a professional. This can help identify potential issues before they become serious problems. Our automotive technicians will inspect your battery each visit.
  • Keep It Cool: Park your vehicle in the shade or a garage whenever possible to minimize heat exposure.
  • Clean Terminals: Regularly inspect and clean your battery terminals to prevent corrosion and maintain a strong electrical connection. Not sure how? Bob & Sons Automotive and clean and recondition your battery!
  • Secure the Battery: Ensure your battery is securely fastened to prevent vibrations, which can cause internal damage.
  • Limit Short Trips + Letting It Sit: Frequent short trips or letting your vehicle sit for long periods of time can prevent your battery from fully charging. Try to combine errands to give your battery more time to recharge during each trip.



Conclusion


Maintaining your vehicle's battery health is essential for a smooth and stress-free summer driving experience. By understanding the effects of heat on your battery and taking proactive measures, you can avoid the inconvenience of a dead battery and enjoy the open road with peace of mind. Remember, regular maintenance and vigilance can make all the difference in keeping your vehicle reliable throughout the hottest months of the year. Safe travels!
