Agree with the rest of the comments about the instructions. I am writing from Mallorca, Spain, and I was just talking to the Bose service provider here and they were telling me the Soundlink III battery problem is common. The price for a new battery installed is around 140€ which for a product that costs between 250€- 290€ is nothing but normal. Lithium batteries and their useful life, nobody tells you about it when you buy their product.
