How to Check Laptop Battery Voltage With Multimeter? [Solved] 2023

As laptops become increasingly more popular, so do the number of people wanting to know how to check their laptop battery voltage with a multimeter. Although most newer laptops have a built in feature that will show you the battery voltage, some people still prefer to use a multimeter. Here is a quick guide on how to do this:

  1. First, make sure that your multimeter is set to the correct setting. For checking laptop battery voltage, you will want to use the 20V DC setting.
  2. Once your multimeter is set correctly, touch one of the probes to the positive terminal on your laptop battery and touch the other probe to the negative terminal. You should see a reading on your multimeter that will tell you what the current voltage of your battery is.
  3. If you are unsure of which terminals on your laptop battery are positive and negative, consult your owner’s manual or look for markings on the battery itself.
  4. Once you have checked your laptop’s battery voltage with a multimeter, you can compare it to the manufacturer’s specifications to see if it needs to be replaced.

Or,

  1. Power off your laptop and remove the battery
  2. Connect the black multimeter lead to the ground terminal on your laptop
  3. Connect the red multimeter lead to the positive terminal on your laptop battery
  4. Set the multimeter to DC voltage mode and touch the leads together to get a reading of 0 volts
  5. Note down this reading as it will be used as a reference point
  6. Touch the red lead to the positive terminal on your laptop battery and take a voltage reading
  7. Compare this reading with the one you took earlier when both leads were touching each other; this will give you an accurate voltage measurement of your laptop battery
