How to Know If Your Car Battery Needs to Be Replaced

While the typical driver around Bryan or College Station changes their battery every four years or so, sometimes batteries fail prematurely. That’s why it’s important to keep an eye out for the red flags of a failing battery, including:

• Dimming headlights
• More frequent need for engine revving or jump starts
• Takes longer to start the engine when you turn the key/push the button
• Unusual power fluctuations

What Causes Car Battery Deterioration?

No matter what battery you buy, all need to be replaced eventually. That’s because there are many factors that cause battery deterioration:

• Heat: When the weather ishot, liquids inside a car battery evaporate. The hotter your climate, the faster you’ll likely need a replacement.
• Vibrations: Your battery is held in place with hold-down clamps. If these clamps break, the vibrations will wear down your battery quickly.
• Needing a Jump: Jump starts can help you out in a pinch in Franklin, but they are rough on your car components. If you find yourself in need of frequent jumps, be sure to schedule a service.
• Time: No matter your climate and car care, your battery can only go through so many charge cycles before it’s done for good. However, proper maintenance will give you the longest battery lifespan possible.

The Headlight Test

1. Keep your car in park while turning on the engine. Make sure your headlights are on.
2. Rev the engine and watch the headlights. Do you notice any changes in the brightness level?
3. If the headlights get brighter, the current is not strong enough to keep the lights at normal brightness while the car is idling. 
4. Visit a service center for further assessment.

Using a Digital Multimeter

1. Set the voltmeter to 20 DC volts.
2. Pop the hood, and touch the black negative terminal to the black negative meter probe.
3. Touch the red positive terminal with the red positive meter probe.
4. Ask a helper to turn on the headlights and check the voltmeter reading.
5. At 80℉, 12.5 volts or higher means your battery is fully charged. 12.3 volts means it’s at about 75% charged.11.8 volts or lower means you have 25% or less charge.
