🔋 Is your Bluetooth headphone battery dying too quickly or not charging at all? In this video, I’ll show you how to replace or upgrade the Li-ion battery in almost any pair of Bluetooth headphones — including headsets, earphones, and even wireless speakers.
✅ You’ll learn:
– How to disassemble your Bluetooth headphones safely
– How to find and replace the battery
– How to upgrade to a higher capacity Li-ion cell (if space allows)
– What type of battery to buy and how to match specs (voltage, size, connector)
This method works on many popular models, including Marshall Major II, generic Bluetooth headsets, and wireless earbuds.
