Hi Guys, This might help co'z I've also been experiencing the very same thing that your having with your Bose, mine is soundlink 3. you just have to remove the buttom panel and the back panel of the unit, unscrew the battery and remove it, you'll notice the foam cushion had been worn out real bad, you just have to add a piece of foam, not too thick just the right amount to keep the battery tightly seated on it's contact. I hope this helps.
