8.0 Storing the UPS
8.1 Storage conditions
The PowerCell should be covered and stored in an upright position, in a cool, dry
location. The PowerCell 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 PowerCell is switched off for storage.
8.2 Extended storage
To achieve expected run time following extended storage, the PowerCell should
be allowed to refresh the battery for 12 hours once every 6 months in environ-
ments 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.
