Excellent instructional video. part was prepped for easy soldering. I didn't even have to strip any wires. I like fixing $300 headphones with a $30 part. I'll be checking in with them for other stuff before I give up and re-purchase anything I don't need to!
This is exactly the mindset we built the site around — no reason to toss $300 headphones over a $30 part. Glad the part came pre-prepped and the video walked you through the soldering without any guesswork. Looking forward to having you back for whatever's next, and thanks for sharing the photo!

Change battery in Bose headphones they work great now
My order was delivered promptly in good condition and a perfect fit for what I needed!
I'm 75 so soldering the small leads was trickly but I did it and the battery works great.
12months in and it works perfect so i'll say at this point it's pretty safe to recommend. It's not that hard to do , but of course bose made it harder than it should be. Ideally discharge the old batter as much as you can before you do this. I sleep in mind so it's gotten VERY heavy use over the last year. I also wear them for work, so maybe 12-14 hours a day of anc.
To central sound thanks for selling a quality battery and keeping these things out of landfills. This is how everything should be. There is no reason to toss these because the battery stops holding a charge.
The replacement battery and how to install it video worked great. Even after buying soldering kit and heat gun I still saved money over the single electronics store option in my area.
