How does a car battery die?

My car battery has regular issues. Why do car batteries die?

Answer
Having an inconsistent battery can be very frustrating, but there could be some simple things you can do to help your car battery last longer.
Some common reasons car batteries die are:
  • Leaving headlights or interior lights on
  • Using accessories, like the radio or infotainment system, while the car engine is off
  • Leaving a door open
  • Leaving your car parked for too long without driving it
If none of the above are true for you, it may be an internal issue. A faulty relay switch, for example, could keep the electricity running through the circuit wall the car is off, which would damage the battery. Additionally, the battery could be corroded or near the end of its life cycle.
In case you are stranded with a dead battery, it’s a good idea to consider roadside assistance. In addition to providing car insurance quotes at an unbeatable price, Jerry offers roadside assistance memberships.
