Jump starting your car often is not only inconvenient, but also risky and dangerous. Every time you are connecting jumper clamps to the battery you unavoidably are causing a power surge and minimal arcing and sparking at the terminals. During each jump a surge of power activates the whole system at once and could cause any of the sensors, security system and infotainment display to malfunction. More significant damage can take place if you mistakenly cross polarity of the jumper cables.

What could cause car battery to die?

Here are some common signs that are good indicators that you will need new battery.

  • Battery age: Automotive batteries are manufactured to last 3 to 5 years. Depending on climate and use some may last more or less. If you are making many short trips or drive in extreme desert like heat you may only get 2 good years out of average battery. It is recommended to test and monitor battery capacity (%CCA) during regular car maintenance and replace as needed.
  • Car sitting not driven: Cars left sitting for a month or more may end up with totally discharged battery. The longer car battery voltage stays below 12v the less chance it can be revived with a jump start. If you leave your car sitting for 2 – 3 months, its almost guaranteed you will need to get a new car battery.
  • Staring slow: When you are familiar with your daily driver it’s easy to notice if anything is off. You may notice it starting a little slower or with slight hesitation. This is your indicator that car battery capacity is diminished and it’s time to replace it.
