Battery Testing
A DC load is well suited to verify that a battery is working properly. 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
battery.
As the accumulator is used by any sheltered equipment or the uninterrupted service system, it is necessary to use
load testing. Because the battery is the weakest component, load testing should be used periodically to ensure the
security of the battery.
Capability test
For the capability test CC mode is used. Generate a program to set the voltage in off state. If the accumulator’s voltage
is too low, the electronic load will interrupt the 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, the battery’s discharge curve could be displayed in
window. This test can reflect the reliability and usage time of accumulator.
Operation:
(1) Turn off the input of electronic load, then connect the load with battery.
(2) Press
I-setI-set
on the panel, VFD displays "CURRENT= A", set discharge current value and press
Enter
to
confirm.
Note: the discharge current should not be more than the current that the battery can supply.
(3) Press

, VFD displays "MIN VOLT= V", set the min voltage value, press
Enter
to start
the test. When the battery voltage reaches as the min voltage, the battery test will stop. During the testing, press
the down key▼and up key▲ to observe the voltage, current and discharge capacity of the battery, and the power
of the load.
(4) Press
