Generally, it takes 2-3 hours to charge a Bluetooth headset, and a fully charged Bluetooth will have a blue indicator on. Bluetooth headset charging precautions are as follows:

1. Newly bought Bluetooth headphones can be fully charged for the first time, and do not need to be charged for too long.

2, Bluetooth headset internal 3.7V 150-500mah lithium-ion battery, lithium-ion batteries do not have a memory effect like nickel-cadmium batteries, so no matter what time to charge, will not affect the use of the battery is too large. The life of lithium-ion batteries mainly depends on the following three points: 1. Overcharge and overdischarge, the normal use voltage of lithium batteries is between 3.6-4.2V. If it continues to be used below 3.6V, it will inevitably affect its life. When the charging circuit fails, the battery with a charging voltage higher than 4.2V will heat up, which will also affect its service life. However, the current battery protection circuits are very advanced, and almost all have over-charge and over-discharge protection. 2. High current or short circuit, too long call, and battery short circuit lead to excessive battery current and heat. It will also affect the normal service life. The brand of Bluetooth headset will not appear for a long time call battery heating, the battery quality is good and the circuit is stable and can be in the normal output range of the battery. 3. The battery is in a low state for a long time, and the battery damage of many Bluetooth headphones is due to this reason. If not used for a long time, the battery is exhausted. Although the battery's protection circuit consumes a small amount of power, it is consumed for a long time, so that the battery is always under the normal voltage of 3.6V, resulting in over-discharge damage of the battery.
an hour or so
If it is a Bluetooth headset, the general charging time does not need to be too long, because an ordinary Bluetooth, and you charge it to about an hour, he can be completely full, so you do not need too long things, and you do not need what is too special method can be carried out a solution, so if this is the case, You can also do a normal processing.
2-3 hours
It takes 2-3 hours to charge a Bluetooth headset
General Bluetooth headphones with charging compartment, charging takes 2-3 hours; Bluetooth headphones that can be directly charged without a charging bay take much less time to charge, about 1-2 hours. A fully charged Bluetooth will have a blue (or green) indicator on.
Of course, if it is used on demand, it will take less time.
