Charge after discharge.
Generally, the first charging of Bluetooth audio takes 2-3 hours. A fully charged Bluetooth speaker can be used for 9-10 hours.
When charging, it is best to shut down and charge, one is good for the battery of the Bluetooth speaker, and the other is faster to charge.
Generally speaking, the red light means that it is charging, and the green light means that it is full. If it is always a red light (charging for more than 3-5 hours), it indicates that there is a problem with the charging circuit of your speaker, or it does not have the full charge stop function. If the charge can be used normally for 1 hour, it is best not to timeout.
If the use of lithium battery, we must be clear that lithium battery is almost no memory effect, can be used with the charge, but the first few times may not reach the best capacity, generally normal charge and discharge 3 times after normal.
