    • Remove the battery.

    • Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.

    • Before installing a new battery remove any remaining adhesive from the headphones, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • Make sure the battery cables are long enough to solder them onto the circuit board before installing new adhesive into the battery well.

Conclusão

If possible, turn on your device and test your repair before installing new adhesive and resealing.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%

Take your e-waste to an R2 or e-Stewards certified recycler.

Hallo, tolle Beschreibung. Vielen Dank dafür.

kann man bei den Bose 700 NC auch den Akku tauschen ?

Würde mich sehr freuen, wenn das so wäre. Hat da jemand evtl bereits schon Erfahrungen gemacht. Könnte mir vorstellen, dass viele 700 NC jetzt auch in das Alter kommen, in dem der Akku schwach wird.

Fk Bose for making it so difficult! They all care about the environment so much, don’t they?!

Batteries should be easily replaceable by any customer by themselves! Ear pads as well. Bose makes it harder so you would throw away your $300 headphones when battery dies. So much waste, plastic and other harmful stuff.

EU mandated to use USB-C on all devices to reduce the waste. Batteries are more harmful. They should make it mandatory for batteries to be user replaceable on tech like headphones. Manufacturers are making disposable headphones in purpose, obviously. Like AirPods and other similar earbuds. 18-24 months and you’re forced to throw them away. They should offer cheap battery replacement for AirPods and like earbuds as well. Maybe trade in deals. $70-$90 a bud isn’t cheap replacement.

Companies are lying about the love for the environment to make us buy more and add more harmful waste to it.

Actually, you can buy the earpads separately, even from BOSE themselves. I’ve replaced mine 3 or 4 times already and it’s pretty straight forward
