30°C
–
Relative humidity: ≤ 95%
–
Dry and clean environment with proper ventilation
–
Away from corrosive and organic substances (including gas)
–
Away from direct sunlight

At least 2 meters away from heat sources (such as a heater)
4. The warehouse keeper should collect battery module storage information
every month and periodically report the battery module inventory information
to the planning department. The battery modules that have been stored
overdue should be recharged in a timely manner.
5. Regional offices or organizations should not store battery modules or
communication equipment configured with battery modules. Prior approval
