GENERAL INFORMATION
Battery Testing
Experiment proves the test with load is the best method to ensure the battery whether work
well or not. Only with the correct load testing, the battery can be confirmed if it was being the
expectant life curve location. The electronic loads can be used to test any type of the battery
nowadays.
As the accumulator is used by any sheltered equipment or the uninterrupted service system,
it is necessary to use the load testing. Because the battery nearly is the lowest reliability
component, so it must use the load testing periodic ensure the security of the battery.
Capability test
Electronic load uses CC mode to do the capability test. Make a program to set the voltage
in off state. The accumulator have too low voltage, electronic load intermits test if system
checks the accumulator which is near to one rating or in insecurity state. In testing
procedure, you could see the accumulator voltage, discharge current, electronic load power
and spare capability of accumulator. If connecting with PC software, discharge curve could
be displayed in window. This test can reflect the reliability and using time of accumulator. So,
it’s necessary to do the test before you change another new accumulator.
Operation:
1. Turn off the load, connect with the tested battery.
2. Press l-set VFD display CURRENT= *****A.
