8.0Storing the UPS

8.1Storage 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.
