Q&A for How to Replace Batteries on an Apple Magic Mouse

Hold down the cover release tab, then wedge a firm, thin object into the space between the mouse's body and the cover, and pry the cover up. You may need to use something like a flathead screwdriver to do this, though you'll need to be extremely careful not to accidentally nick the batteries as you pry.

Make sure the mouse has batteries and is turned on. Go to System Preferences, press "Mouse," and press "Set Up Bluetooth Mouse." Click the mouse you are using.

Various fixes such as putting tin foil at the positive end or scratching the contact areas provide temporary relief. Look carefully at the positive contact on the mouse. One may be recessed into the housing. Fill the space with some conducting material and it may work.

Any alkaline AA battery should work in your mouse.

If your mouse doesn't have a battery cover, you're using a Magic Mouse 2, which is charge-only. You can't take the cover off without physically dismantling the mouse.

Go to the store where you bought the mouse from, and bring your mouse and batteries. The salespeople should be able to help you.

There should be a screw on the side. Use a coin to twist it until it comes out, then tip out the batteries.

You can check the Apple store, or check online retailers to find a charger that fits your specific needs.

If the Duracell batteries work ok, then stay with them.
