powered up will gradually diminish. When this time is less than 45 minutes, the battery should
be replaced. This test tests the actual capacity of your battery by fully discharging it while
recording the time elapsed.
If the SkyView system has more than one display with a backup battery installed, perform the
test for each display individually. Power off all but one display during the test.
Test Procedure
1. Fully charge the SV-BAT-320 Backup Battery. Reference the Battery Charging section for
battery charging instructions.
2. Turn off all other displays except for the one you are currently testing.
3. Disconnect primary power from the SkyView display—ensure that the display is not
powered from another source.
4. During the 30 second power off countdown, press the TEST BAT button above button 8
(far right button).
5. The BATTERY TEST screen will appear displaying the status of the test. Note that while
the test will last 60 minutes. If the SV-BAT-320 is able to power the system for at least
45 minutes, the battery passes this test.
6. To see the results of the test enter the SETUP MENU > LOCAL DISPLAY SETUP > BATTERY
BACKUP (SV-BAT-320) STATUS>TEST RESULTS. Make sure the TEST RESULT says PASS.
7. The BATTERY TEST can be aborted by pressing the PWR OFF button.
Repeat the test procedure for each backup battery /display in the system.
This test discharges the backup battery. Recharging the battery after the test is
recommended. Do this by applying primary power of >12.25 volts to your SkyView
system. The backup battery is fully charged when its voltage reaches 12.25 volts.
If a tested battery does not pass the initial backup battery test, please contact Dynon Avionics
