4-1-3 Estimated backup time
The backup time varies depending on the capacity of connected devices.
After calculating the total capacity of connected devices, refer to the graph of the backup
time to obtain an estimation of the initial value of the backup time. (This is also applied to
checking the battery.)
1
. Convert the total capacity (power consumption) of the connected devices to watts (W).
For the indication of connected devices, check your computer and the rear of the dis-
play. The indicator can show values in three different ways: volt-amperes (VA), am-
peres (A), and watts (W).
For devices that use the VA or A indication, convert the capacity into W. Multiply the
value indicated on devices by the value in the right table for conversion.
(When the power factor is unknown, enter “1”. The power factor usually ranges between
0.6 and 1.)
2
. Add the values converted into W to obtain the total capacity of the connected devices.
3
. Calculate the initial value of the backup time for the total capacity of the connected de-
vices from the graph below.
Graph of backup time (graph of initial values for products that have not been used at
25°C).
The backup time becomes shorter than the graph (table) below when temperature is
lower.
The smaller the capacity of connected devices becomes, the longer the backup time
becomes.
