Introduction

Follow this guide to replace a worn-out or dead battery in your Logitech G535 headset.

It’s natural for batteries to lose capacity as they age. If your headset dies quickly and doesn't hold a charge, it may be time to replace the battery.

For safety, perform this repair when your battery is below 15% charge. Any charged lithium-ion battery can be hazardous if punctured or damaged. If your battery looks puffy or swollen, take appropriate precautions.

Installing an ear pad onto the cup can be tricky. Be patient and work slowly—it may take a couple tries.
Orient the ear pad so the wider part is at the top.
With one hand, firmly hold an ear cup steady.
With your free hand, place the pad over the top of the cup, so the black fabric flap slips over the cup's plastic lip.
Thread the rest of the flap over the lip, working your way around the entire cup. Gently stretch the pad as necessary.
Check the entire perimeter of the cup to make sure the ear pad is fully on. If any of the fabric flap is sticking out, try to push it over the lip or remove the ear pad and try again.
