Even the best computer mouse will need to be recharged at some point. For some models, this means opening up the battery cover and replacing the batteries. Keep reading if you’re wondering how to change the battery in a wireless mouse. We’ll detail each step so that you don’t have to stress about getting your mouse back in working order.

KEY TAKEAWAYS:

  • First, you’ll want to disconnect your mouse from power by turning it off. After this, ensure you have your mouse’s correct type of batteries.
  • Next, you’re going to open the battery compartment cover. For most, these just pop out without an issue. However, some models might require a screwdriver.
  • Finally, it’s time to pop out the old batteries and put in the new ones. Make sure you replace all batteries present since combining old, and new ones can cause problems.

Replacing Batteries in Wireless Mouse Devices

There are several different types of mice out there. Because of this, you’ll always want to read the manual that comes with your mouse to determine how to remove the battery cover and figure out what type of batteries your mouse takes. If you’re wondering why your mouse is not working, it might very well be low battery life. This can cause other problems and could even explain why your mouse won’t scroll.

Insider Tip

Some mice have an indicator light that tells you your battery life.

STEP 1 Find the Correct Fresh Batteries

You’ll first want to ensure you have the right batteries for your mouse. Most of them will work with a AA battery, while others might need a AAA battery. You can find out which battery your mouse takes by looking at its current battery or reading the manual that came with it. You should also disconnect it from power by turning the mouse off.

STEP 2 Open the Battery Compartment

Next, it’s time to open the battery compartment. You’ll likely find this on the bottom of your mouse by flipping it over and looking. Most of them will just pop open with little effort. However, others may need a screwdriver for you to get them open. Either way, make sure you get it open.

STEP 3 Switch out the Replaceable Batteries

Finally, it’s time to switch out the batteries. Make sure you replace every battery present. Sometimes a mouse might use two, for example. Mixing old and new batteries can be a recipe for disaster, so replace both, if you replace them at all. If you have an Apple Magic Mouse, you might want to read our Magic Mouse tips.

What if my mouse doesn’t take standard batteries?

You might have to go to a specialty store if you have a mouse model that takes a less common battery. It shouldn’t take too much effort to find one of these stores.
