8.0Storing the UPS

8.1Storage conditions

The UPS should be covered and stored upright in a cool dry location. The UPS should be stored with its Battery packs in a fully charged state. That is, the indicated battery capacity should be 100% before the UPS is switched off for storage. Once charged, disconnect the Battery packs from each other and from the UPS.

8.2 Extended storage

To achieve expected run time following extended storage, the UPS should be allowed to refresh its batteries 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 its batteries every 3 months.
