Logitech G PRO Wireless Battery Replacement

Introduction

Follow this guide to replace the battery on a Logitech G PRO Wireless mouse.

Replacing the battery on a G PRO Wireless mouse requires removing the mouse feet. If you plan to reuse the mouse feet, you’ll need to apply heat to loosen the adhesive and remove the feet with minimal bending. Bent or torn mouse feet may require replacement feet.

For your safety, discharge the battery below 25% before disassembling your mouse. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

What you need

  1. Logitech G PRO Wireless Battery Replacement, Turn off the PRO Wireless: step 1, image 1 of 3 Logitech G PRO Wireless Battery Replacement, Turn off the PRO Wireless: step 1, image 2 of 3 Logitech G PRO Wireless Battery Replacement, Turn off the PRO Wireless: step 1, image 3 of 3

    • Shift the power switch down to turn off your mouse (when the PRO Wireless label is oriented right-side up).

    • The color behind the switch should be red when the mouse is switched off.

  2. Logitech G PRO Wireless Battery Replacement, Apply heat to the upper mouse foot: step 2, image 1 of 1

    • If you plan to reuse the mouse feet, you'll need to apply heat to loosen the adhesive and remove the feet with minimal bending.

    • Heat an iOpener and apply it to the upper mouse foot for one minute.

    • A hair dryer or heat gun may also be used, but be careful not to overheat the mouse—the internal battery is susceptible to heat damage. If you use a hair dryer or heat gun, set it to the lowest temperature setting and apply heat for 10 seconds.

  3. Logitech G PRO Wireless Battery Replacement, Insert the spudger under the upper mouse foot: step 3, image 1 of 2 Logitech G PRO Wireless Battery Replacement, Insert the spudger under the upper mouse foot: step 3, image 2 of 2

    • Insert the flat end of a spudger under the upper mouse foot.

    • Each mouse foot has a gap in its recess that you can use to insert the spudger.

    • The mouse feet are made of two layers. Make sure you insert the spudger under the bottom layer to completely remove the foot.

    • Slide the spudger under the length of the upper mouse foot to cut through the adhesive and detach it from the mouse.

    • Work slowly to avoid bending the mouse foot. If the adhesive becomes difficult to cut through, remove the spudger and apply more heat.

  10. Logitech G PRO Wireless Battery Replacement, Adhesive information: step 9, image 1 of 1

    • If you're going to install replacement mouse feet or apply new adhesive, use the flat edge of a spudger to remove the remaining adhesive in the mouse foot recesses.

    • If there's any adhesive residue left, use isopropyl alcohol and a microfiber cloth to remove it. Allow the surface to completely dry.

    • During reassembly, follow this guide if you are using a pre-cut adhesive card to secure the mouse feet.

  11. Logitech G PRO Wireless Battery Replacement, Remove the lower case screws: step 10, image 1 of 1

    • Use a Phillips screwdriver to remove the seven 4.4 mm-long screws securing the lower case.

    Edit

  12. Logitech G PRO Wireless Battery Replacement, Lift the bottom end of the lower case: step 11, image 1 of 2 Logitech G PRO Wireless Battery Replacement, Lift the bottom end of the lower case: step 11, image 2 of 2

    • Don't try to remove the lower case from the upper case yet. They are still attached by the battery cables and input cable.

    • Lift the bottom end of the lower case about 1 cm away from the upper case.

    Edit

  13. Logitech G PRO Wireless Battery Replacement, Pull the lower case down: step 12, image 1 of 2 Logitech G PRO Wireless Battery Replacement, Pull the lower case down: step 12, image 2 of 2

    • The lower case has clips on its top edge attaching it to the upper case.

    • Pull the lower case down about 0.5 cm to detach the lower case from the upper case.

    Edit

  14. Logitech G PRO Wireless Battery Replacement, Swing the lower case away from the upper case: step 13, image 1 of 3 Logitech G PRO Wireless Battery Replacement, Swing the lower case away from the upper case: step 13, image 2 of 3 Logitech G PRO Wireless Battery Replacement, Swing the lower case away from the upper case: step 13, image 3 of 3

    • The battery cables and input cable are connected to the bottom right of the lower case (when the PRO Wireless logo is facing you).

    • Swing the lower case left to right away from the upper case.

    Edit

  15. Logitech G PRO Wireless Battery Replacement, Place the mouse on your work surface: step 14, image 1 of 1

    • Place the lower case on your work surface.

    • Lean the upper case against a sturdy object (such as a box) to prevent straining the cables.

    Edit

  16. Logitech G PRO Wireless Battery Replacement, Disconnect the battery: step 15, image 1 of 2 Logitech G PRO Wireless Battery Replacement, Disconnect the battery: step 15, image 2 of 2

    • Be careful during this step, as the socket is very fragile—don't use extreme force.

    • Use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.

    • If you're having trouble, try rocking the connector side-to-side to loosen it.

    • During reassembly, make sure the battery connector is oriented correctly when you insert it into its slot. The red wire should be on the side where the motherboard is marked with a plus sign (+).

    Edit

  17. Logitech G PRO Wireless Battery Replacement, Disconnect the input cable: step 16, image 1 of 2 Logitech G PRO Wireless Battery Replacement, Disconnect the input cable: step 16, image 2 of 2

    • Use the pointed end of a spudger or your fingernail to flip up the small, hinged locking flap on the input cable ZIF connector.

    Edit

  18. Logitech G PRO Wireless Battery Replacement: step 17, image 1 of 2 Logitech G PRO Wireless Battery Replacement: step 17, image 2 of 2

    • Use a pair of tweezers to pull the input cable out of its ZIF connector.

    • The white line on this ribbon cable marks the edge of the connection area. To reinstall, insert the cable into the connector up to this line, and then close the locking flap. If the cable doesn’t insert easily up to (or very near to) this line, it’s probably misaligned and needs to be gently removed and repositioned.

Worked entirely fine for me. Since I bought replacement sliders/feet as well, I just skipped the warming up steps. The glue still separated very easily and overall took me like 10 seconds to remove all feet

Regarding the battery/flex-cable step, I personally removed the flex cable first as it’s much more fragile and less replaceable than the battery cable

I also removed the logic board to clean the area below, it’s pretty straight-forward. The only thing one has to remember is where the on/off switch colors go again during re-assembly. Answer: the blue side is at the bottom (when the PRO Wireless label is readable and NOT upside-down), you can find a photo in step 10

The symptoms I had before the repair were a bit weird, which is why I initially wasn’t sure if it’s the battery or not. Basically, my mouse wouldn’t charge a lot, but also wouldn’t work for a long time while connected via cable. Both of these appear to be fixed now (I’ll try to remember to update this comment if it turns out to be broken)

For a replacement battery, I managed to find an original battery on eBay that was disassembled from a returned mouse. That way I could be sure I’m not going to receive some potentially dangerous knock-off version, which I didn’t want to risk.

The locking flap on the input cable ZIF connector just broke in half when I tried this teardown. Would you happen to know where I can buy a replacement, if there's any?

It is absurd how hard it is to replace a battery on such a simple device. It should be a simple turn and lock mechanism and Logitech should sell replacement batteries directly to the consumers. I guess this way is more profitable because most people including me will never do it!

Anybody know of a good battery to use as a replacement? I searched a while back and couldn't find a source I was confident in.

Note to all - I'm assuming the battery must run in series with the power/data cable. So if you are having battery issues (battery not charging) and waiting for the replacement to arrive, you can remove battery re-assemble and use the mouse plugged in/switched off as if it were wired in the interim!
