Yeah this guide is just like the original Bose Mini which looked like that model had a way to replace the batter easily. I purchased a battery off Amazon thinking it was the same. This is not the same. The Bose Mini II has a battery hard-wired directly to the board. Might be too late but read this guide’s comments first to get the low down. The guide is very misleading. The BOSE SOUNDLINK MINI II **DOES NOT HAVE A REPLACEABLE BATTERY**
