18) If there is dirt on the battery pack interface, please use a clean and dry brush, toothpick, or dry cloth to clean it.
Otherwise, poor contact may be caused, resulting in energy loss or failure to charge.
Carge
1) The battery pack will automatically stop charging when fully charged. It is recommended to disconnect the
charger after the battery pack is fully charged.
2) Please make sure that the battery is turned off before plugging in the charger.
3) When charging the battery, please ensure that the battery is charged within sight to prevent unpredictable
accidents.
4) When charging, please pay attention to ensure that the environment around the battery has good heat dissipation,
and there are no flammable and explosive items such as sundries.
5) Please keep the intelligent battery pack closed when charging.
6) The intelligent battery pack must be charged with a special charger officially provided by Unitree Robotics.
Unitree Robotics will not be responsible for all the consequences caused by using a charger not officially provided by

7) When charging, please place the battery pack and charger on the cement floor and other surrounding areas without
flammable and combustible materials. Please pay attention to the charging process to prevent accidents.
8) It is forbidden to charge the battery pack immediately after the robot runs. At this time, the battery pack is in a
high temperature state, and forced charging will seriously damage the life of the battery pack. It is recommended to wait
for the battery pack to cool to room temperature before charging. The ideal charging ambient temperature (5°C -40°C)
can greatly prolong the service life span of the battery pack.

source, or a heating furnace. The ideal storage temperature of the battery pack is 22°C -28°C.
3) During storage, please pay attention to ensure that the surrounding environment of the battery has good heat
dissipation and is free of sundries and other inflammables and explosives.
4) The environment where the battery pack is stored shall be kept dry. Do not place the battery pack in water or
where water may leak.
5) It is forbidden to mechanically impact, crush or pierce the battery pack. It is forbidden to drop or artificially short
