Battery Safe Operation Guide
Improper use, charging or storage of batterys may result in fire or property and personal injury. Be sure
to use the battery in accordance with the safety instructions below.
Recommended use
1) Make sure the battery has enough battery before each use.
2) When using, moving or charging, please be careful with the battery and charging plug to avoid being
damaged by external force.
3) When the power of the battery is lower than 40%, stop using the robot as soon as possible, replace the
battery with a new one or charge the battery.
4) It is normal for a battery that has just been used or charged to generate heat.
5) It is forbidden to contact the battery with any liquid. Do not immerse the battery in the liquid or wet it.
Short circuit and decomposition reactions may occur when the inside of the battery meets water, which may
lead to spontaneous combustion of the battery or even explosion.
6) It is forbidden to use batterys not officially provided by Unitree Robotics. If the users need to replace
it, please go to the official website of Unitree Robotics for relevant purchase information. Unitree Robotics is
not responsible for battery accidents, operation failures and machine damage caused using batterys not

Do not plug and unplug the battery when the power supply of the battery is turned on, otherwise the power
supply or the robot may be damaged.
9) The batterys should be used at an ambient temperature of -15°C-55°C. If the temperature is too high
(higher than 55°C), the batterys may catch fire or even explode. If the temperature is too low (lower than -
15°C), the life span of the battery will be seriously damaged.
10) t is forbidden to use the battery in strong magnetic field or electrostatic environment. Otherwise, the
batterys protection board will fail, resulting in the failure of the batterys and the robot.
