JBL Charge 3 won't power on after battery replacement

Hello all,

I replaced the battery in a customer's Charge 3, and now it is acting strangely. When I try to charge it, it shows that the battery is charging/charged, but when I take it off of USB power it turns off immediately and I can't power it back on. When it's plugged in it turns on, but won't connect to Bluetooth. I read some suggestions to factory reset it, but none of the button combinations I found have any effect. Does anyone know what else I can do to get it up and running?
