2.4.1 Battery Back-Up Time Test
Purpose: Describes how to measure the back up capacity of batteries.
This test provides the measurement of back-up time during power outage by actually
discharging the batteries. The back-up time is load as well as battery dependent, thus
more back-up time is available with a lower load (in Amps or Watts) and less time with
more load.
Tip: It is recommended to perform this test every 6 months.
Tip: Make sure the batteries are fully charged before starting this test.
PROCEDURE
EXAMPLE:
Start time is 1PM.
ON BAT contact if selected, is activated.
Low Battery Alarm LED appears at 4PM. LOW BAT
contact at selected value will be activated.
Low Battery capacity battery back-up time will be the
time difference between 4PM and 1PM or 3 hours.
Shutdown time is 5PM.
Battery reserve time will be the time difference
between 4PM and 5PM or 1 hour.
The Total Battery Back-up time is the sum of Low
Battery capacity back-up time and Battery Reserve
time or the time difference between 5PM and 1PM or
4 hours.
