Logitech G935 Battery Replacement

Introduction

Follow this guide to remove and replace the battery on a Logitech G935 headset. You may need to do this repair if the battery no longer holds a charge.

For your safety, discharge the battery below 25% before disassembling your device. 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

Step 1 Turn off the headset

Do not try to completely remove the battery from the headset. It is still attached by the cable connector in the top right of the battery recess.
While removing the battery, keep it as close to the recess as possible to prevent straining the cables.
Pull on the tab at the top of the battery to dislodge it from the recess.

Step 5

Remove the battery from its recess.
During reassembly, place the bottom of the battery in the recess, then press the top of the battery into place.
Make sure the battery cable isn't trapped under the battery before pressing it into place. The cable should fit in the gap on the right side of the battery recess.

Step 6

Place the headset on your work surface so that the buttons are facing up.
Place the battery on your work surface so that it is laying flat with the battery information facing up.
Place the battery as close to the ear cup as possible to avoid straining the cables.
You may need to twist the ear cup for the battery to lay flat.

Step 7

While holding the battery connector slot, pull the battery connector out.
Hold the battery connector slot and battery connector by their plastic frames and not by their cables to prevent damaging them.
If necessary, pull the battery connector with a rocking motion to "walk" it out of its slot.
You may need to use your fingernails to pull the battery connector out by its shelf.
When inserting the battery connector, make sure it is oriented correctly. The red cable on the battery connector should line up with the red cable on the battery slot.

Step 8

Remove the battery from the headset.
This headset has a plastic reinforced battery pack. You can reinstall the original battery if needed.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order.
