JBL T450 Wireless Headphones: Overcharged 9hrs, Won't Connect, White LED On - Battery Issue?

Question

Hello.
I have a problem, I bought the JBL T450 wireless headphones. After unloading I connected them for the night. However, it turned out that the charging time was 3 hours, and I charged 9 hours. Now the headphones do not want to connect and the white LED for charging is on. Will they unload themselves? Is it possible that I have reloaded the battery? Please help.

Charging time does not matter, the device has a built-in system to prevent overcharging of the battery. Probably they will be discharged themselves, only after what time? This is not known. Is there no reset button there?

After 15 seconds of holding the switch, they worked, But now there is another problem .. Well unloaded headphones connected to the charger. I landed 3h as it is written on a box, after which after disconnecting from the charger the headphones do not turn on, no diode is burning ..

I do not know how it is in these headphones, maybe after disconnecting from the charger, when the headphones are charged, the diode does not burn at all, and only when the battery is weak it signals it with a diode?
From what I've been looking at, it's when these headphones are turned on after pressing the power button for more than 2 seconds

Did you read the user manual for these headphones?

Good morning,
It seems to me that I have a similar problem - the headphones were connected for charging overnight, in the morning I noticed that the diode is still on.
According to the instructions, just after charging, it should go out. The headphones do not respond to attempts to turn on, and the device with which they were paired does not find them.
Could the author of the post write whether he was able to integrate / continue to work? And if it was sent to him for guarantees, has it been recognized?
Thank you in advance for your reply, greetings.

If the headphones are on warranty then use it.

I had the same problem.
In a situation when the headphones have discharged, I connected them to charging and left them overnight. In the morning they did not give any signs of "life" anymore.
I gave them back for a guarantee and got back charged and working with information that everything is ok. Nothing has been repaired.
Now I'm meeting this problem again.
Someone managed to solve this puzzle? After all, I will not take them to the warranty shop after each discharge.

I checked the problem on similar headphones. It was true that they were not up to jbl but the behavior was identical, connecting the headphones via the current meter to the usb did not indicate any power consumption at all. The problem was solved in the following way. I got into the headphone battery, shortly through the power supply (about 20 seconds) I initiated the connection of the power source to the battery (in my case 4.5 volts, 150 mA.
After these actions, the battery "revived" and after connecting the usb power indicator, the meter showed that the headphones are charging.
It is possible that the system can not initiate charging because it is too deep.

Maybe you're right. Only in my opinion it is a factory defect. I gave back the second (second) handset to the complaint - now I am waiting for the service response in this matter.

Hi, I have the same headphones, and after charging about 4 hours, a white LED came on and nothing was happening, I couldn't turn on or squeeze the headphones. I read that someone held down 15 seconds and it worked and in my case also.
