5 Signs Of A Failing Battery

Of all the components in your car, the battery is one of the most important. Without a properly functioning battery, your car won't start or will act weirdly, leaving you stranded and frustrated. Unfortunately, batteries don't last forever, and some signs indicate your car battery is starting to fail. Here are some of the most common symptoms of a failing car battery that you should be aware of.

Slow Engine Crank 

One of the most common signs of a failing car battery is decreased cranking speed. When you try to start your car, you may notice that it takes longer than usual for the engine to turn over. This is a sign that the battery is weak and may not have enough power to start the engine.

Dim Headlights And Interior Lights

If you notice that your headlights or interior lights are dimmer than usual, it's a sign that your car battery is losing its charge. This is especially noticeable at night or when you turn on the headlights, as they may appear to be flickering or not as bright as usual.

Check Engine Light

If your car's check engine light comes on, it may be a sign of a failing battery. The check engine light can come on for many reasons, but one of the most common is a low battery charge/insufficient power. It's important to have your battery tested as soon as possible to prevent further damage to your car's electrical system.

Swollen Battery Case

If you notice that the battery case is swollen or bloated, it's a sign that the battery is overheating and may fail soon. This can be caused by overcharging, high temperatures, or damage to the battery itself. If you notice this sign, it's important to have your battery replaced as soon as possible to prevent damage to your car's electrical system.

Strange Smells

If you smell a strange odor coming from the engine bay of your car, it may be a sign of a failing battery. A sulfur or rotten egg smell is a sign that the battery is leaking and the acid is reacting with other components under the hood. This can be dangerous, so it's important to have your car checked by a mechanic.

In conclusion, a failing car battery can be frustrating and dangerous. If you notice any of these signs, have your battery tested and replaced if necessary at Don Lee's Tire & Auto. A healthy battery is essential for your car's ability to function properly - make sure to keep an eye out for any signs of trouble.
