Why does the battery in the wireless reader die overnight?
The battery in the wireless scanner supports both the decoding circuit and the RF motherboard. When the reader is not working, its decoding circuit partially stops working, but the RF motherboard is still in constant contact with the associated base station within the communication distance, even if the base station has been shut down, it is also constantly searching. The rechargeable battery can last up to 12 hours when the reader is not in use, so it should be recharged during the night to ensure adequate support for the next day.
