BOSE Head Phone 700 (See remarks) (PO12 Alverstoke)

Bose Noise Cancelling Headphones 700 with case, purchased August 2022.
Battery cannot be replaced "official" by BOSE, however, number of DIY options available on the Net. See link below as example.
I do not have the skills to perform a replacement.
There is nothing wrong with the speakers/head phones/blue-tooth!
