For the love of God, don’t try to follow these instructions. They are worse than useless. I wasted 2 hours and over $60 between the battery and new screwdrivers and the end result is that I can’t even get the battery open to change it. Also, when I tried to put the cover back on the tab broke off so now my speaker is completely useless. (Prior to attempting to fix it, it still worked great when it was plugged in). I would have been better off just buying a new speaker for a little more than 2x the cost of the battery, considering that now I’m going to have to do that anyway. Thanks for absolutely nothing (except scamming people into buying replacement batteries from you).
