The treatment method is as follows:
If it is idle for a long time, to activate the headset battery, it needs to be charged for at least 3 hours, and individual needs to be charged for 8 to 12 hours.
for the following reasons
In a long idle state, if the lithium battery pack has been discharged due to self-consumption, and the system static power consumption. When the lithium battery pack (polymer cell) battery is discharged to a voltage below 2.8-3.3V, the low voltage protection of the Bluetooth chip is triggered. At this time, the Bluetooth headset cannot be turned on, or it automatically turns off after being turned on. Prompts the user to charge, at this time if the user charges in time, the headset can be charged normally.
If it is not charged in time, as time goes by. The battery will continue to consume power until the battery voltage falls below 2.7-2.4V. The battery protection IC triggers the overdischarge protection.
The battery protection IC will turn off the mos tube, at which point the battery stops output power. Only battery protection ics and cell consumables continue to consume power. Bluetooth headset press to turn on, there will be no response.
Charging the Bluetooth headset at this time will remove the overdischarge protection of the protection IC, and the headset (charging IC) will provide a trickle charge to the battery to a voltage higher than 2.8-3.0V. Then the headset starts to return to normal charging current.
If it is idle for a long time, to activate the headset battery, it needs to be charged for at least 3 hours, and individual needs to be charged for 8 to 12 hours, if it is still not activated, the battery may be broken.
It could be a broken charger or cable.
Take out the Bluetooth battery wrapped in plastic wrap, then put it in a plastic bag, and then put it in the refrigerator for 2-3 days, the package should be carefully not to let water into, you can also fill some absorbent materials. After the freezing time is up, the battery is taken out and placed for 1 to 2 days, and then the Bluetooth battery is charged and activated for use test. Only lithium batteries and lithium polymer batteries can be operated in this way, and cadmium nickel batteries are prohibited from being frozen in the refrigerator. The principle of this method is that the battery is inside the battery liquid, the reason why the battery aging is caused by the solidification of the battery liquid, the battery is frozen at low temperature, so that the battery liquid is all solidified, so that it can automatically melt, absorb excess water, and then fully charged, you can activate the battery liquid.
If it is not used for a long time, it should be charged in the headphone compartment first. After it is fully charged, it will start automatically. If it is not started, long press the headphone head, and then the headphone can be connected when it flashes.
Wireless headphones are still a new thing, the development time is not long, in the rising period, user demand continues to increase, the user's expectations of wireless headphones are also increasing, which is a new test for the industry.
