Signs Of Battery Deterioration

A car battery typically lasts 3-5 years. Signs of deterioration include slow engine crank, dimming lights, and frequent jump-starts. Regular maintenance helps prolong battery life.

Slow Engine Crank

When the car battery is getting old, one of the most common signs of deterioration is a slow engine crank. This happens because the battery is losing its capacity to provide enough power to the starter motor. It is important to note that a slow engine crank can also be caused by other issues, such as a faulty starter motor or alternator. However, if you notice a slow engine crank, it is best to have the battery checked to ensure it is not the culprit.

Check Engine Light

Another sign of battery deterioration is a check engine light. When the car battery is not functioning properly, it can cause a variety of issues with the vehicle’s electrical system, which can trigger the check engine light. If you notice this warning light, it is important to have the battery checked as soon as possible to avoid further damage to the vehicle.

Battery Case Swelling

Battery case swelling is another sign of battery deterioration. When a battery is exposed to high temperatures or is overcharged, it can cause the battery case to swell. This is a serious issue because a swollen battery case can lead to battery failure or even a dangerous explosion. If you notice any swelling or bulging in the battery case, it is important to replace the battery immediately.

In conclusion, these are the most common signs of battery deterioration that you should be aware of. By keeping an eye out for these warning signs, you can avoid being stranded with a dead battery and ensure that the vehicle is always running smoothly. Remember to have the battery checked regularly by a professional to ensure it is functioning properly and to avoid any potential issues down the road.
