8.0 Storing the UPS
8.1 Storage conditions
When you store the UPS, cover it and keep it upright in a cool, dry loca-
tion. Store the UPS with its battery fully-charged. Before storage, allow the
UPS to charge for at least 8 hours. Disconnect any accessories and cables
connected at the computer interface port, because these may unnecessarily
drain the battery charge.
8.2 Extended storage
To achieve optimal run time after extended storage, you should refresh
the UPS’s batteries every 6 months in environments where the ambient
temperature is –15 to +30°C (+5 to +86°F).
For extended storage in environments where the ambient temperature is
+30 to +45°C (+86 to +113°F), you should refresh the UPS’s batteries every
3 months.
