How Do You Open a Logitech Mouse Battery Compartment?

If you're having trouble with your Logitech mouse, like your pointer is skipping or drifting, or you can't locate your pointer at all, the problem is most likely your battery needs to be changed. Unless you are using a Logitech rechargeable wireless mouse, this is just a matter of taking off the battery cover, removing the old batteries, and installing the new ones.

Replace the Batteries From the Bottom

If you have a Logitech mouse that has a bottom battery compartment, it should be easy to change the batteries out.

  1. Flip your mouse over and slide the Power switch into the Off position. Depending on the model mouse you're using, this could be located anywhere on the bottom.

  2. Find the battery door—you'll see a seam that runs across and around a portion of the mouse. It usually has an arrow on it to indicate the direction you should push it and there may even be a depression for your thumb.

  3. With gentle pressure, push the battery compartment door down and in the direction of the arrow. It should slide out revealing the batteries.

  4. Remove the old batteries and replace them with new batteries, making sure to match the polarity marked on the battery case or the bottom of the battery door (generally speaking, the flat side of the battery goes toward the spring).

  5. Once you've replaced the battery or batteries, put the battery door back in place and turn the mouse back on. It should automatically reconnect to your computer.

Replace the Batteries From the Top

If you're using a Logitech mouse model with a top battery case, you'll need to release the lock on the battery door before you can open it.

  1. Turn your mouse over and slide the Power switch to the Off position.

  2. Then locate the battery door lock release. This is probably located near the power button, and you may either have to press and release it, slide and release it, or slide and hold it until the door is open.

  3. Once you have the button in the correct position, look at the top of the mouse for a seam for the battery compartment. Once you find it, you'll either slide the plastic covering the battery compartment or you may have to pry it up. Use gentle pressure to remove it.

  4. When the battery compartment door has been removed, remove the old batteries and replace with the new ones being sure to insert the new batteries properly.

  5. Then slide the battery compartment cover back onto the mouse and turn the Power back On. Your mouse should automatically reconnect with your computer.

How Do I Change the Battery in My Logitech Wireless Mouse?

If you're changing the batteries in your Logitech mouse, there are a few things you should keep in mind as you work through the process:

  • Always use fresh batteries. If you use old batteries, the mouse might not work, which could make you think something is wrong with the device when in truth it's just dead "new" batteries.
  • Use firm, but gentle pressure when removing the battery compartment door. You don't want to push too hard if the door slides, because the downward pressure could prevent it from sliding. Likewise, you don't want to pry too hard and break something when the battery compartment door is actually a push door.
  • When in doubt, refer to the Logitech website to find specific instructions for your model of mouse. Since there are different types, it's possible the instructions here are not appropriate for the mouse you have.
