• Condition of battery
• Current load presented by the computer terminal
• Time required to change the lift battery
• Ambient temperature
As the battery ages, the run time (time the UPS powers the
computer terminal without external power) slowly decreases. The
UPS is designed to operate in a temperature range of
-30 °C to
50 °C (-22 °F to 122 °F). However, it is recommended that
charging be done within the temperature range of -15 °C to
40 °C (5 °F to 104 °F).
