Signs That Your Car Battery Needs to Be Replaced

Knowing how often to replace a battery can save you from being stuck somewhere outside Carlsbad. So, what are the most common warning signs of a failing battery? If you notice any of the following, you should schedule an appointment with MINI of Escondido to get a replacement battery installed as soon as you can.

  • Headlights are dimmer than usual

  • Your car’s engine doesn’t turn over right away when you start it
  • You experience unusual power fluctuations

How to Test a Car Battery

The experienced service team at MINI of Escondido is available to professionally inspect and test your car battery for you. However, if you can get to our Service Center, here’s how to test a car battery on your own:

Headlight Test: 

  1. Start your car, keep it parked, and turn on your headlights. 
  2. Rev the engine and watch to see if the brightness of your headlights changes.
  3. If you notice fluctuations in the brightness, it’s an indication that the current from the battery isn’t strong enough when idling, and you should bring your vehicle into MINI of Escondido for further assessment.

Digital Multimeter:

  1. Open the hood of your car and set the voltmeter to 20 DC volts. Then touch the negative terminal (black) to the negative meter probe (also black).
  2. Repeat this step by touching the positive terminal (red) with the positive meter probe (also red).
  3. Have someone turn on your vehicle’s headlights, and check the voltmeter reading.
  4. At a temperature of 80 degrees Fahrenheit, 12.5 volts or higher indicates a full charge; 12.3 volts indicates a 75% charge; 11.8 volts or lower indicates a 25% or less charge.

How Much is a Replacement Car Battery?

If it’s time to get a new battery, you can count on finding the right battery for your MINI Cooper in the Parts Center at MINI of Escondido. How much is a replacement battery? A standard car battery can cost anywhere between $75 and $120. Premium batteries can cost up to $200, and batteries for hybrid models are often priced even higher than that.
