Why Teardown Instead of Replace?
A wireless headset’s lithium-ion battery typically lasts 300–500 charge cycles. After that, runtime drops noticeably. Common signs include:
-
Calls cutting out early
-
Frequent charging
-
The headset not reaching a full charge
-
The base flashing a charging error
The rest of the headset — speaker, microphone, wireless radio, and controls — often works perfectly. Replacing only the battery is the most cost-effective and environmentally friendly fix.
