How to properly jump start your car

Today’s ICE (Internal Combustion Engine) car is a terribly complex piece of machinery with some 30,000 seperate parts working together. One of the most important parts in your engine compartment is the least noticed, but probably the most important.

We are of course talking about the 12 volt battery.

If you are unfortunately experiencing starting anomalies, we understand the dread. However before seeking – oftentimes – expensive diagnosis; let us help you freely check if the battery is dying.

Top free ways know if the battery is slowly dying

1. Difficulty Starting Your Engine

  • The most common sign of a failing battery is when your car takes longer to start. Each time you turn the ignition key, the battery works to power the starter motor. If the battery is losing its charge, it will struggle to deliver the necessary power, leading to delayed engine start times.

2. Dimming Headlights and Electrical Issues

  • If your headlights are dimmer than usual, especially when the car is idling, it could indicate a battery struggling to maintain power. Other electrical components, like your car’s dashboard lights, radio, or air conditioning, may also function erratically or with reduced efficiency.

3. Warning Lights on the Dashboard

  • Many cars have a battery warning light on the dashboard that illuminates if there’s an issue with the battery or the charging system. If this light comes on, it’s a direct signal that you should check your battery and charging system.

4. Corrosion Around Battery Connectors

  • Visible corrosion on the battery terminals or connectors can be a sign of a failing battery. The corrosion is usually a white, ashy substance that builds up around the terminals, which can affect the battery’s ability to charge and provide power.

5. Swollen Battery Case

  • A battery case that appears swollen or bloated is a clear indication of a failing battery. This usually happens due to excessive heat causing the battery to expand. A swollen battery should be replaced immediately as it can lead to a poor performance and can even be dangerous.

If you notice any of these signs, it’s wise to have your battery tested by a professional. Most auto parts stores will perform a battery test at no charge. Early detection can save you from being stranded with a dead battery and can also ensure your vehicle remains reliable and safe to drive.
