Einleitung
Use this guide to replace a worn out or dead battery in your Logitech A20 X Lightspeed wireless headset.
The li-ion battery resides within the right ear cup.
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.
If possible, drain the headset's battery before you begin repairs. You'll hear an audio beep every 30 minutes when the battery's low.
