Why Car Battery Maintenance Matters
Your car's battery is its beating heart, delivering the power needed to start the engine and run essential systems. Neglecting battery maintenance can leave you stranded or facing an unexpected replacement. Fortunately, with a few simple steps, you can extend your battery's lifespan and keep your vehicle running smoothly.
How to Maintain Your Car Battery
1. Keep Your Battery Clean
Over time, dirt and corrosion can accumulate on battery terminals, disrupting electrical flow. Regular cleaning is essential to ensure proper performance.
- How to Clean Your Battery: Mix baking soda with water to create a paste, then use a terminal brush to gently remove buildup. You can also use a handy battery terminal cleaning kit. Rinse with clean water and dry thoroughly.
- Pro Tip: Apply a thin layer of petroleum jelly on the terminals to help prevent future corrosion.
2. Inspect and Tighten Connections
Loose or damaged cables can cause intermittent issues or a failure to start.
- What to Look For: Frayed wires, cracked insulation, or terminals that wiggle when touched.
- Fix It Fast: Tighten loose connections using a wrench and replace damaged cables promptly.
3. Check Battery Fluid Levels
Most car batteries are sealed, but if yours has removable caps, it's worth checking the fluid levels.
- How to Check: Remove the caps and ensure the electrolyte covers the battery plates. If low, add distilled water (never tap water) to bring it to the recommended level.
- Safety Tip: Wear gloves and goggles to protect against acid splashes.
How to Protect Your Battery from Extreme Conditions
In Hot Weather
Summer presents unique challenges for car batteries. To help minimize the effects of the heat, here are a few tips:
- Park in shaded areas to minimize heat exposure.
- Inspect for corrosion often
- Check fluid levels more frequently, as heat accelerates evaporation. (if needed)
In Cold Weather
Winter has different challenges for batteries. Here are some tips to help keep your car battery healthy in the winter:
- Park in a garage out of the elements.
- Use a battery blanket or insulator to keep your battery warm.
- Ensure your battery is fully charged, as cold weather can significantly reduce its capacity.
Driving Habits That Affect Your Battery Life
Avoid Frequent Short Trips
Short drives don't allow your battery to fully recharge. This can lead to sulfation—a buildup of lead sulfate crystals that reduce battery performance.
- Pro Tip: Combine errands or take your car for a longer drive periodically to maintain a full charge.
Turn Off Accessories When Parking
Leaving headlights, interior lights, or the radio on when your engine is off can drain your battery quickly.
- Reminder: Double-check that everything is off before exiting your vehicle.
Signs Your Car Battery Might Be Failing
Recognizing the early signs of battery trouble can save you from an unexpected breakdown:
- Slow Engine Crank: The engine takes longer than usual to start.
- Dim Lights: Headlights or interior lights appear weaker.
- Dashboard Warning Light: The battery or alternator warning light illuminates.
- Clicking Sound: You hear a clicking noise when turning the key or pushing the start button instead of the engine cranking.
If you notice any of these symptoms, it's time to drive over to the closest Batteries Plus to have your battery tested.
