Checking the Battery Level

Before replacing the battery, it is important to check the current battery level of your MX Master 3. This can be done by using the Logitech Options software or by pressing the battery indicator button on the bottom of the mouse. If the battery level is low, it is time to replace the battery.

Gathering Supplies

To change the battery in your Logitech MX Master 3, you will need a new AA battery, a small Phillips head screwdriver, and a clean cloth. Make sure to use a high-quality AA battery to ensure optimal performance.

Removing the Battery Cover

Turn your mouse over and locate the battery cover on the bottom. Using the small Phillips head screwdriver, gently unscrew the cover in a counterclockwise direction. Once the cover is loose, remove it and set it aside.

Removing the Old Battery

Carefully remove the old battery from the compartment and set it aside. If the battery is stuck, you can use the small screwdriver to gently pry it out. Be sure to dispose of the old battery properly.

Inserting the New Battery

Take your new AA battery and insert it into the compartment, making sure the positive (+) and negative (-) ends are facing the correct direction. The positive end should be facing towards the top of the mouse.

Replacing the Battery Cover

Once the new battery is in place, carefully screw the battery cover back on in a clockwise direction. Make sure it is securely fastened to avoid any issues with the battery connection.

Testing the Mouse

After replacing the battery, turn your mouse over and press the battery indicator button. The LED light should turn on, indicating that the battery is properly connected and the mouse is ready to use. You can also check the battery level in the Logitech Options software to ensure it is fully charged.
