Chosen Solution
so i replaced the battery on my charge 2 plus with the one listed on ifixit websiteJBL Charge 2 Plus Battery Replacement . when i plug it int to charge the battery it just flashes on the first battery light forever. so i reset the charge 2 by holding the phone and volume up button at the same time and now it turns on when plugged in and makes a really loud but deep beeping sound over and over even if its connect to my phone. Any help would be great.
Switch the polarities on the batteries (red+black wires)
Switch red exterior wire with black exterior wire, and red interior wire with black interior wire. It worked well for me when replacing battery. make sure wire colors match the previous battery
