How to Test a Car Battery with a Multimeter
- First of all, you need to have a voltmeter or test light, and both work well for testing a car battery
- If you don’t have either one, you can use a household multimeter
- Next, open the hood and locate the positive and negative terminals on the battery
- The positive terminal will usually be labeled with a “+” sign, while the negative terminal will be labeled with a “-” sign
- Now that you’ve located the terminals, touch the red lead from your voltmeter or test light to the positive terminal, and then touch the black lead to the negative terminal
- If the voltmeter or test light lights up, then your battery is good; if not, then it’s time for a new one! 4
- If you’re using a household multimeter to test your car battery, set it to the “20V DC” setting before touching the leads to the terminals (as described above)
- Then simply read the voltage displayed on the screen; if it’s 12 volts or higher, then your battery is good!
