Why It’s Important to Check Your Car Battery Voltage

Safety GlassesA car battery doesn’t die all at once. It’s composed of separate cells. As these cells start to go bad one by one, the battery begins to die. Checking your battery at least every six months will help ensure that you stay on top of battery maintenance.

What You’ll Need to Check Your Battery Voltage

Just like with any type of maintenance, it’s important to have the right materials before you begin. It’ll ensure your safety and make sure you get the job done right.

First, you’ll want to read your vehicle’s owner’s manual, which will acquaint you with the car’s specific parts and their functions. Then, you’ll want to acquire the following items:

• Safety glasses
• Protective gloves
• Digital Multimeter

These supplies can be found at your local auto parts or hardware store.

Step 1: Prep the Battery

Prep Battery Most batteries are located in the front of the vehicle and under the hood, but some can be found in the trunk.

Once you find the battery, you’ll want to make sure it’s clean. If you find any corrosion, it can be easily scrubbed away with a little bit of baking soda and water. You should also check for any leaks. If you find them, take your vehicle to a professional to have the battery replaced.

Step 2: Test the Battery

First off, you’ll need to make sure your car is off before you test the battery. Keeping the engine off will help to ensure that you’re safe from electrocution during the test.

To begin testing, you’ll need to set the multimeter to the lowest voltage setting that’s above 15 volts. Once that’s done, firmly attach the positive red lead to the corresponding red positive terminal. The black, negative lead can then be attached to the corresponding negative terminal.

Step 3: Getting the Results

Battery Voltage Reader Once both leads are attached, the multimeter will give you a reading. Now, you just have to know what numbers to look for.

Any reading between 12.77 and 12.65 volts means your battery is fully charged. A reading between 12.24 and 12.29 volts indicates that the battery is only about half charged. At this point, you may want to begin testing it more often or even begin to think about getting it replaced. If you receive a reading at or below 11.89 volts, your battery is essentially dead and in need of replacing.
