8 Signs of a Dying Car Battery

December 16, 2020

A dead car battery is a common problem in the winter season. Sometimes, it's due directly to the freezing temperatures, but that's not always the issue at hand. There could be many different reasons why your battery is weak and/or dying. Here are some of the warning signs you can look for, according to the Colorado Springs auto repair specialists at LightHouse Automotive :

1. Car Won't Start

This is a pretty obvious sign that the battery is dead. If you turn the key or hit the start button and it makes no noise (or maybe just a few light clicks), then it's probably the battery that needs to be recharged or replaced. It could be a failing starter, alternator or spark plug, as well, so make sure to look at more than just the battery.

2. Dim Lights

If your interior lights, headlights or other exterior lights are flickering or dim, then this is a common sign that your battery is growing weaker and may need to be replaced soon.

3. Malfunctioning Electronics

The car's battery powers a lot of different things inside the vehicle. When it is losing power or dying, it may not be able to handle everything all at once. You may notice some electronics issues like the stereo cutting out or power windows/doors not working correctly. This could be a dying battery, bad wiring or some other electrical problem that needs attention.

4. Bad Smell

If you open your hood and notice a strong sulfur (rotten egg) smell, that is usually the battery. It may have a leak and the odors will let you know that it is significantly damaged.

5. Corroded Terminals or Bulging Battery Case

If you look at your battery and things don't look right, it's a pretty good indicator that something is wrong. Corroded terminals are common with leaking battery acid, which reduces the battery's ability to recharge. A bulging battery case or any other physical issues are other signs of leaks and battery damage. You will generally need to replace your battery right away when significant damage to the case or terminals can be seen.

6. Old Age

Most car batteries have a lifespan of 3-5 years. Some don't even last that long. Some hang in there for longer. When you start experiencing some of the issues above and you know you haven't replaced your battery in several years, it's a pretty clear sign that it's time for a new one.

7. Check Engine Light

The check engine light can come on for any number of reasons. It is essentially a "catch all" for a variety of automotive problems and tripped sensors throughout the vehicle. It could be the battery or it could be something else.

8. Battery Light

Last but not least is the battery warning light itself. If that comes on, it usually means there is a low charge or no charge remaining at all. 

These are some of the common signs of car battery failure.
