Signs of a Dying Vehicle Battery 

Fortunately, it’s not likely that your car battery will reach the end of its life before showing a few signs of wear and degradation. Like many vehicle parts that start to break down, a failing car battery will often produce a few red flags that drivers will notice. 

When your battery is dying, it’s likely that your vehicle will experience issues with its interior and exterior lights. Dim or nonfunctional headlights, taillights, dome lights or dashboard lights can all be the result of a battery problem. Other warning signs include an active check engine light, ignition clicking, a bulging battery case and a sulfuric odour coming from under the hood. 

How Long Do Car Batteries Last? 

There are many factors that determine how long a vehicle battery will last. Most service technicians will tell you that the average car battery will last about three to five years. Vehicle owners living in cold climate environments typically need to replace their batteries less often than those who live in areas with high temperatures, as excess heat can significantly shorten a battery’s lifespan.

Tips for Increasing Automotive Battery Longevity 

To get the most out of a new car battery, there are several tips and strategies drivers should keep in mind. The most important factor is for vehicle owners to drive their vehicles regularly, as long stretches of inactivity will cause the battery to lose its charge. Other ways for drivers to increase their car battery’s life include: 

  • Remove power-draining accessories when not in use
  • Check for loose cable connections every few months
  • Check for and remove battery terminal corrosion 
  • Take your vehicle in for routine maintenance
