Shipping and Storage Requirements
The PowerTrust UPS can be shipped or stored under the following (non-operating)
conditions and environmental limits:
• The UPS/BATTERY switch must be in the
• Temperature limits:
• Electronics Unit, Service Bypass Unit, and Battery Box: −40° to 70°C (−104° to
158°F)
• Battery Pack: The shelf life of a battery pack depends on the temperature of the
storage area. The charge on a battery should not be allowed to drop below 50%.
Figure 2-7 shows how long a battery pack takes to reach a 50% charge at 40°C
(104°F), 30°C (88°F), and 25°C (77°F). Figure 2-8 shows the time for the battery
capacity to decrease to 50% over temperatures ranging from 18°C (64°) to about 54°C
(129°F). For example, if a battery pack has been stored at 20°C (68°F), it should be
recharged after about 800 days or about 27 months. If it has been stored at 50°C
(122°F), it should be recharged after about 60 days or 2 months.
