Can I perform a car battery maintenance myself?

If you’re comfortable under the hood of your vehicle, some battery maintenance tasks are not that difficult. First up, check your battery terminals for signs of corrosion. This can appear like a white or green chalk around the posts and terminals. If you spot any, give it a good cleaning with a soft bristle brush like an old toothbrush. Make sure the fasteners are all secure and then add a good measure of dielectric gel to the posts and terminals to prevent corrosion.

How long does a car battery replacement take?

Car battery replacement is usually very quick to complete from start to finish. With a qualified auto mechanic, the entire process can typically be completed in as little as 20 to 30 minutes.

How do you test a car battery?

Our certified technicians use top-of-the-line battery testers called multimeters that test the charge to see if it falls within the normal operating range specified by your vehicle’s manufacturer. Unless you have the tools and knowledge to do so correctly, it’s recommended to bring in your vehicle for a free battery check.

How can you keep your battery running longer?

The best way to keep your car battery lasting longest is with preventative maintenance. A knowledgeable technician can check your car’s voltage, tighten fasteners, clean the battery, and apply anti-corrosion dielectric gel. Also, if you can, you should try to avoid frequent short trips. The repeated start, stop, start cycle can drain your battery’s cranking power. Other things to be mindful of include not leaving lights on or accessories plugged in and minimizing using any power when the vehicle is off.

How do I know if my car battery needs to be replaced?

There are definitely some signs that signal it’s time to bring your vehicle in for a battery replacement. These include: Your vehicle headlights are exceptionally dim. Your vehicle struggles to turn over. A jump start doesn’t work or you have to keep doing them. You hear a clicking noise when you turn the key. Your vehicle’s dashboard is lit up like a Christmas tree. Off-smells like sulfur or burning rubber. If you experience any of these with your vehicle, it’s much easier to bring in your vehicle before it dies completely than to be stranded somewhere. Schedule your free battery check now.
