2.3. Charging for Battery

The battery should be fully charged before first use. Charging from 0% takes approximately 4.5 hours, providing over 15 hours of operation. This test was conducted under typical power consumption in industry applications: indoor room temperature 20-30 degrees Celsius, with SurPad, RTK five-star connection, coordinates collected every second, and Bluetooth, Wi-Fi, and mobile network enabled, with automatic screen brightness and volume. The adapter includes overcharging protection.

Note: To maintain optimal battery performance, follow these instructions:

• Use the dedicated adapter provided with the receiver.
• Charge the battery as needed, rather than waiting until it is completely flat.
• Do not charge the device when the surrounding temperature is above 45°C or below 0°C.
• It is advised to perform a full charge every 3 months if the device has not been used for a long time, as prolonged charging can impact the battery's full capacity.
