If the batteries are dangerously close to being worn out, a low priority alarm "REPLACE
BATTERY" will be generated.
The batteries must be replaced as soon as possible (see chapter 7.3).
NOTE: if the manual test is started immediately after installation or after a power failure, the
UPS may generate a false "replace battery" alarm as the batteries have been (partly)
discharged during transport/storage or during the power failure.

4.4.3 Deep Battery Test

The calculation of the autonomy shown by the LCD, is based on the actual load and (initially)
on the condition - and thus capacity - of new batteries.
Due to ageing of the batteries this capacity will deteriorate, and gradually there will grow a
difference between the calculated autonomy (shown in the screen) and the real autonomy.
During a deep battery test the UPS will check and store the actual capacity of the batteries.
This information will be used during future autonomy calculations.
In order to ensure accurate autonomy prediction we advise to execute a deep battery test on a
regular basis: every 6 months under normal operating conditions.
If battery operation occurs more than once a week, the interval between the tests should be
shorter.
Software start: please refer to the manual of the appropriate monitoring software package for
more information.

The test status (indicated by the second line) can be:
= testing.
= the test has been completed succesfully.
= the test could not be executed properly: not all test
conditions were fulfilled.
= battery capacity too low to start the test.
a deep battery test can be started via the front panel under the
following conditions:
- the load should be more than 30% of the nominal load;
- the batteries should be fully charged, this means that they should
not have been (partly) discharged during the last 24 hours;
- no alarm situation may exist.
