简介
Bose doesn't sell batteries for the NC700 and doesn't seem to make replacements. I couldn't even find a Chinese equivalent. In this guide, I describe the process of replacing the original battery with a universal battery.
Please do not try this again unless you have a basic knowledge of electronics and have never soldered.

Thank you, very useful and money saving
Happy to help.
Cool! how did you knew the battery was the issue? Did you have the red/white blinking LED issue on your headphones? I got that issue since the end of last year, and am not quite sure if it is a software or hardware related issue. Would love to fix it but indeed couldnt find any official replacement batteries or anything.
Yeah, I had the same problem. I think there's a bug in these headphones. If the battery is very low, the headphones think there is no battery and don't charge it.
