They don’t work.
Wouldn’t charge like other reviewers have stated so had to return. Also the silver trim on the batteries just dropped off. Poor quality.

Problem was resolved swiftly
I bought 2 batteries for my ageing Bose Quietcomfort 3 headphones. On arrival one of the batteries was a dud.I reported it to the seller and they replaced the failed battery without a fuss and didn’t require me to return the dud one.So far they seem ok for the task.

Rubbish
Battery purchased worked on delivery, but when it required recharging, it wouldn't charge. By which time the Amazon refund period had expired - steer clear!
