Chosen Solution

Just purchased this Bluetooth speaker and it’s not powering on. I’ve charged it for the recommended time and when I press the power button, the light flashes on then goes off. Connecting it with my iPhone, to test its charging abilities, I have to hold down the button in order for a discharge to go to the phone. I may have a defective problem but I wanted to see if a solution as to how to fix this issue was here first. Thanks!

Same here after I dropped it, 2 years warranty this was a replacement for a dropped Jbl Charge 1, it was replaced instantly at there service department without question, I dont think i want to open it to take a look in case they dont change it again, if only i can find the receipt…. There is a teardown in french on youtube but i cant even get the ends off. https://www.youtube.com/watch?v=IElTLOlA

the battery I bought was inverted. You must invert black and red conductors to have good polarities
