8.0 Storing the UPS
8.1 Storage Conditions
The UPS should be covered and stored in an upright position, in a cool, dry location. The
UPS should be stored with the battery in a fully charged state. This means that the UPS
should be allowed to charge the battery for at least 6 hours before the UPS is switched off
for storage.
8.2 Extended Storage
To achieve expected run time following extended storage, the UPS should be allowed to
refresh the battery for 12 hours once every 6 months in environments where the ambient
temperature is -15°C to +30°C (5°F to 86°F). For extended storage in environments where
the ambient temperature is +30°C to +45°C (86°F to 113°F), the UPS should be allowed
to refresh the battery for 12 hours once every month.
