NOT CHARGING JBL Bluetooth Earbuds! Can we fix them?

In this video we are looking at a pair of JBL Earbuds (Under Armor Sport Wireless), which stopped working.
The earbuds do not turn on and do not charge over the micro-USB cable at all anymore.
We take a look at the battery inside of one of the earbuds and explain how to make them work again.
So in the end the earbuds are able to accept a battery charge and function again as expected.

Thanks for the video! I opened mine up and the battery read 0v. It did charge up to 3.7 but when I tried to turn the headset on it immediately dropped to 0. I'm guessing it's completely dead and this trick won't work but I'll give it an hour of charge and hope for the best.

Hello I have headphones JBL Harman Under Armour Sport Wireless Pivot for 3 years. When I try to charge them fully, they are at 60% and they discharge quickly. Can you help me and explain how can I change the battery. Do you know the reference of the battery also. Thank you for your help
