If you believe your car's battery is going bad, there are some things you can do to test it. If you need a new battery, head to Dallas Collision Center in Dallas, TX for a compatible replacement.
Start by visually inspecting the battery to look for corrosion on the cable connections and battery terminals. Look at the date code on your battery to see how old it is. Most vehicle batteries last approximately three to five years. You can also have a mechanic do professional testing and inspection.
Use a multimeter to determine your battery's voltage. Read the owner's manual for this tool to ensure that you are using it properly. Ideally, your battery should test at approximately 12.6 volts when it is healthy. A load test is another option. Most auto parts stores have a load tester that you can purchase. You want to get a score above 9.6 volts when your battery is in good condition.
