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 

   START

 

 

 

 

 

Disconnect the incoming Utility 

Power 

 

 

 

EXAMPLE:

 

Start time is 

1PM

. 

   ON BAT contact if selected, is activated. 

 

 

 

 

 

 

Front Panel LCD indicates ON 

BATT. Battery supplies the 

power to the load. Record the 

start time

 

 

Low Battery Alarm LED appears at 

4PM

. 

   LOW BAT contact at selected value will be activated. 

 

 

 

LOW BATT is displayed 

 

 

 

 

Low Battery capacity battery back-up time will be the time 

difference between 4PM and 1PM or 

3 hours

. 

 

 

 

The time between the two is 

the LOW BATTERY 

CAPACITY back-up time 

 

 

Shutdown time is 

5PM

. 

Battery reserve time will be the time difference between 4PM 

and 5PM or 

1 hour

. 

 

 

 

 

Record the time when the unit 

shuts off. (Both LEDs are off 

and the LCD display indicates 

STANDBY) 

 

 

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. 

 

 

 

 

TURN ON the incoming Utility  

Power for recharging the  

batteries

 

 

    

RUN TIME TEST COMPLETED
