How to Change Battery in Dell Wireless Mouse? (9 Simple Steps & Possible Issues)

As devices go, the mouse is one of the most useful and often necessary parts of any computer. They help us do every task – and as such, we want them in their best working order.

Dell is, of course, one of the best brands to invest in, boasting high-quality products with long service life. Their wireless mouse has the added advantage of giving our hand freedom of movement and can connect to many devices from long range.

But, like all great tools, your mouse may fail at some point. Chances are high that the problem relies solely on faulty batteries, which you must change as soon as possible.

In this article, we’ll explore everything you need to know about changing the batteries of a dell wireless mouse. We’ll discuss how to properly assess battery status and examine your mouse for any other potential problems.

Like any technology, a lot can go wrong with your wireless mouse. And it’s important to spend some time diagnosing and assessing what might be potentially wrong with your equipment.

So how can you tell if the batteries require replacement?

  • Battery-status light: Quite often, when the batteries fail, there will be a flashing amber light on the top of the mouse. This suggests that it is incredibly low on power. This will not continue indefinitely, as this warning light will turn off when the battery reaches zero.
  • Wireless pairing error message: Certain error messages on your computer screen that appear may explicitly state low battery levels are causing your connection problems.
  • Delay: If the mouse pointer on your computer screen is slow to move, lags, or is unresponsive, this is also a tell-tale sign that your battery power is running low.
  • Buttons: If your left or right buttons, or scroll wheel, periodically stops working when you click them, this can suggest that your mouse is gradually losing power.

Step-by-step on changing the batteries of a dell wireless mouse

Changing the batteries of a dell wireless mouse is quite straightforward. But given how important (and expensive) your mouse can be, we’ll talk you through how it’s done.

NB: Do remember that there are hundreds of different brand models, each of which may have slight variations in buttons, light colors, and more.

  1. Turn the power switch off the other wireless mouse.
  2. Using your fingertip, gently pry off the battery compartment from underneath the mouse. Often, a groove or arrow tells you which direction to pressure.
  3. Remove the battery/batteries from their compartment. Examine the springs and coils for damage, corrosion, or lose fittings.
  4. Place new batteries inside, paying close attention to correctly matching the positive and negative sides. Most mice use AAA batteries or AA batteries.
  5. Gently slide the side of the mouse cover back over the battery compartment.
  6. Power on your wireless mouse. Check that the light turns on inside.
  7. Connect to your PC or laptop. If your mouse connects via Bluetooth and has a connection-mode button, press it twice to start pairing mode.
  8. Some models of dell wireless mice have a second Bluetooth connection light to signal when a successful pair has been achieved.
  9. If your mouse connects via a USB transceiver, insert this into your computer, install the relevant drivers, and wait for the connection.

Your wireless mouse is acting up

Replacing your battery is simple and will often only take a few minutes. But it may only be part of your problems. Below are some other issues that can affect your mouse in tandem with bad batteries, alongside possible solutions.

  • USB Port: If using a Dell universal USB dongle, ensure your actual USB ports are working properly first. Connect another device to them and see if it is working as expected. If not, you may need to repair your USB hubs. You can also try your USB dongle on another port, or device, to see if it registers with the new system.
  • Accessories: Disconnect things like port replicators, as these may not have sufficient power to register a connection between the mouse and your PC.
  • Bluetooth Icon: If your connection type is via Bluetooth, ensure the icon appears in the bottom right corner of the desktop to show your PC detects your wireless mouse. If not, your mouse may not be in Bluetooth range. Move closer and repeat the pairing process – the light should turn solid white when activated.
  • Device manager: If using Microsoft Windows, open your device manager to see if other wireless devices are appearing or not. Consider updating or reinstalling your drivers to correct this problem, as your machine may send and receive errors to all wireless equipment preventing them from connecting properly.
  • Rechargeable battery: If using rechargeable batteries, you must also consider if they are faulty themselves. They have a lifespan of between 2 to 5 years before they become obsolete. Also, check that they’ve been properly recharged to full before installing them into your wireless mouse.
  • Optical sensor: If the light turns on and off repeatedly underneath your mouse, you may need to clean the sensor. Sometimes, dirt and debris can block it from registering movement, and this is what is causing the slow lag to appear from your mouse movements.
  • Dell wireless keyboard: Using multiple Dell wireless accessories can complicate and dilute the signal. Consider deactivating your Dell keyboard to see if this improves the function f the mouse.
  • Buttons: If your mouse works slowly, test your left and right buttons to ensure they aren’t stuck and freeze your mouse’s movements. Sometimes if a button is jammed, it impedes the other sensors and workings of the mouse.
  • Broken? Check your Dell warranty terms and any additional hardware warranty. You can be entitled to a complete replacement if a battery change has little effect. Even a limited warranty offers some protection from the place of purchase for 1-year.

Now that you’ve remedied your battery problem, there are ways to extend your dell wireless mouse’s lifespan and power levels. One of the caveats to using wireless technology is that it can be quite demanding on batteries.

So, how can you extend them?

  • Turn off? If your wireless mouse is not in use, e.g., you’re using a touchpad or don’t require the mouse pointer, you should turn off your device. Even if your mouse seems off – many are motion-sensitive, and a slight nudge will power them back on.
  • Distance: Regardless of if your mouse is working through Bluetooth or a USB receiver, it will have to work harder if there is a greater distance between it and your computer. Additionally, a longer distance can distort the connection, meaning the mouse spends more resources to prevent signal loss.
  • Conserve battery power: If using Chrome, Android or Windows, switch your mouse to Bluetooth low energy mode. This ensures that battery consumption is kept to a minimum while preserving functionality.
  • Light-colored surfaces: Wireless mice detect radiation reflected from the surfaces they move across to work. Dark surfaces absorb more radiation than light, making your mouse work harder to register movement. Use a light-colored mouse mat or table surface to ease power consumption.


Dell-branded products are regarded as some of the best in the market, promising years of continued use. But, like all great tools, at some point, even the best Dell wireless mouse will fail.

Depending on how your mouse acts, it can be a range of problems, including bad connectivity, a fault or damaged part, or the most likely scenario – a low battery level.

As our article has shown, changing your Dell wireless mouse’s batteries is incredibly easy. All you need to remember is to be gentle when opening and closing vulnerable compartments of the mouse and ensure you set the batteries correctly inside.

Additionally, you must ensure that the batteries you replace are fully charged. Always pair your mouse with your PC as soon as possible to eliminate the batteries as the problem.

If you still have questions about changing the batteries of your Dell wireless mouse, including on a specified make or model number, please leave a comment below.

But always remember:

  • Flashing or blinks are a sure sign of low battery power
  • Never force open the battery compartment. It should have a groove or arrow stating your direction to slide it open.
  • Sync the mouse and test if it’s fixed as soon as the batteries are replaced.
  • If you’re unsure about any part of your mouse and afraid of opening it, examine the manufacturer’s manual for physical characteristics, dimensions, and specifications to guide you.
