Introduction

Follow this guide to replace a worn-out or dead battery in your Logitech Zone Wireless 2 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.

What you need
