Get to Know Your Car’s Battery

Your car's battery provides the necessary jolt to power every electronic component in your vehicle, such as your lights, stereo, GPS, or wipers, even short-term when the engine is off. Primarily, it kickstarts your engine, setting the wheels in motion. But its duties double as a guardian for your car's computer, shielding it from surges.

What Caused My Car Battery to Die?

Your car battery typically boasts a lifespan of three to five years, so if you haven’t replaced your battery within that timeframe, it most likely died from long-term use.

If you have received battery service in recent years and your battery has died, harsh elements like extreme cold or heat, corrosive forces, or insecurity of its position can weaken it prematurely. Or, an often cause, you left a light on in your cabin when parked or used electricity without engine power for a long period of time.

There also may be a deeper issue affecting the battery, like an ailing alternator, a worn-out starter, or a sneaky broken wire – often hiding in plain sight.

 
How To Fix a Dead Car Battery

Many drivers know that kickstarting the engine with the help of another vehicle can bring the engine back to life. However, in the case that your car’s battery needs to be replaced, this is a surprisingly simple service!

Here's a step-by-step guide to get you back on the road:

  1. Safety First: Before anything else, ensure your car is parked in a flat area and turned off, and put on safety gear for your protection.
  2. Disconnect Cables: There should be two cables connected to the battery by terminals. The positive terminal is red and marked with a "+" sign, and the negative is black with a "-". Using a wrench or pliers, loosen and remove the cable clamps. Start with the negative cable, then the positive.
  3. Take Out the Old Battery: Locate the battery and release it from any securing brackets. Carefully lift the old battery out of its tray, being mindful of its heavy weight.
  4. Clean the Battery Tray: Wipe down any corrosion or dirt from the tray to ensure a secure fit for the new battery.
  5. Install the New Battery: Place the new battery in the tray, re-securing it with the bracket if applicable.
  6. Reconnect Cables: Attach the positive cable first, followed by the negative. Ensure they are snug but not overtightened.

With the right equipment and procedure, you can do this service yourself at home!

 
Protecting Your Car Battery

Maintaining the efficiency of your car battery is key to preventing unexpected dead battery scenarios. Here's some practical advice:

  • Regular Drives: Every time you drive, you are charging your battery. Take your car for a spin regularly, especially if it sits unused for extended periods.
  • Keep It Clean: Periodically check for corrosion on the battery terminals and clean them using a mixture of baking soda and water.
  • Secure Battery: Ensure your battery is securely fastened in its tray to prevent excessive vibrations that can weaken its performance.
  • Temperature Control: Extreme temperatures, whether hot or cold, can affect battery life. When possible, park in a covered area or shade to reduce exposure.

Remember, proactive care goes a long way. For further advice about your car battery, you can always turn to us for advice.
