I have a bose soundlink mini 2 that suddenly wont turn, i diagnosed it and in short the battery died. I have confirmed this that after removing (following ifixit guide) the battery i measured the voltage on the positive and negative wires and it read 0 volts, battery died. I bought a replacement (not from ifixit, although it was tagged as “original” but it could be fake) and replaced the battery as per ifixit guide. It turns on now no problem. The probem starts when i play music with heavy base. at 40% volume it plays no problem , but at 50% it sounds that the base is clipping or something like that, at 80% when a heavy base comes the soundlink mini outright shutsdown and reset. Have anyone experienced this problem? Could it be the battery? I really dont have a bench powersupply that can give it a high headroom of power. Or im just unlucky and i have a burnt circuit inside
Drake Jest, This sounds like the device can’t get enough power from the battery in order to perform as expected. I don’t have experience with this particular device, but most devices like this you can use both with power connected “on top” of battery. If you connect external power, and then run same tests again, does it still do this? Many low quality aftermarket batteries don’t hold enough power to perform like original. It’s always best to purchase batteries (as most things) from reputable vendors. They do their own QC and they have a great return policy, should there be issues. If you connect external power, and the problem disappears, you know 100% that the battery is at fault.
