Friendly Reminder :
①After the battery is placed for a period of time, it enters a dormant state, and the capacity is lower than normal. Multiple normal charge and discharge cycles are required to activate the battery and restore normal capacity.

②When the speaker is charging the battery, it needs to be charged at an ambient temperature between 5 °C and 35 °C, otherwise the charge indicator will go out, causing the battery to fail to charge.

③When the speaker is not used for a long time, it takes a long time to activate your machine to activate the battery self-protection state. Only after breaking through this state can the battery be charged and used normally.

④Before the speaker needs to be charged, do not expose the speaker to rapid temperature changes, direct sunlight, or moisture, which may cause the battery to be damaged in high temperature or humidity and fail to charge.
