Battery or wiring seems fried by a power surge Bose Quietcomfort 20 ea

I had a perfectly good set of Bose Quietcomfort 20 ear buds, battery working well, charging quickly and lasting ages.

ANSWERS:

"@billwatkins start by replacing the battery. It may no longer hold a charge.

This video and part two of it on here should work for that. Different model same idea. Definitely not an easy job...."
