When the UPS does not need to be installed immediately, the UPS must be stored indoors to be protected from the
excessive moisture or overtemperature environment. The battery requires dry and low temperature, well-ventilated
environment for storage, and the most suitable storage temperature is 20° C ~ 25° C.
During the battery storage, the battery must be periodically charged according to the battery instructions. When the battery is
charged, you can connect the UPS to the mains temporarily to charge and activate the battery.
