The Mini Wireless Optical Mouse uses two AAA batteries. Expect these batteries to die every three to six months, depending on how frequently you use your mouse. When the batteries drain down, you'll be unable to establish a connection with the mouse's USB receiver. You'll need to install new batteries immediately if you want to continue using the wireless mouse.

  1. 1

    Flip your mouse over to view the bottom side. On the bottom, you'll find the "Battery Cover Release" button. Press this button to unlock the battery cover. Turn the mouse back over to expose the top side.

  2. 2

    Place two fingers on the rear-edge of the mouse. Slide your fingers backward to slide the battery cover away from the mouse. Now you'll be able to see the two batteries.

  3. 3

    Remove the old batteries with the tips of your fingers. Position the mouse with the scroll wheel facing away from you.

  4. 4

    Insert the first battery into the right-side of the compartment. The protruded battery post should be facing the scroll wheel on the right side.

  5. 5

    Insert the second battery into the left-side of the compartment. The protruded battery post should be facing away from the scroll wheel on the left side.

  6. 6

    Replace the battery cover. Slide it forward with the tips of your fingers to reattach it. You should hear the cover snap on.
