7. Measuring the backup time (checking the discharge time of the battery)
(3) Calculate the initial value of the backup time for the total capacity of the connected devices from the graph
below.
● Graph of backup time (initial value for product that has not been used)
● The smaller the capacity of connected devices becomes, the longer the backup time becomes.
● The maximum backup time is 90 minutes even if a power failure occurs without load.
(Output is stopped when 90 minutes elapse.)
