Detailed Battery Status Check
Enter the Display Hardware Information Page (SETUP MENU > LOCAL DISPLAY SETUP > BATTERY
BACKUP (SV-BAT-320) STATUS to check the status of the battery.

BATTERY CONNECTED (BATTERY DETECTED): YES / NO
o SkyView automatically sets this to yes when a battery is installed.

LAST BATTERY SHUTDOWN:
o NORMAL
o ABNORMAL: The last shutdown of SkyView did not happen normally.
o WEAK BATTERY: SkyView detected a low battery voltage condition when SkyView
was last shut down. The battery may be discharged or may need replacement.
SkyView will annunciate a warning if this happens repeatedly.

DATE OF LAST TEST: UNTESTED / MM-DD-YYYY
o If this date is over a year ago, SkyView will annunciate BATTERY TEST NEEDED upon
startup. Follow the steps in the Initial / Recurrent Backup Battery Test section below.

TEST RESULT:
o FAIL: VOLTAGE DROP TOO HIGH: Battery likely needs to be replaced. Contact Dynon
Technical Support (contact information at the beginning of this manual).
o FAIL: LASTED xx MINS: Battery likely needs to be replaced. Contact Dynon Technical
Support (contact information at the beginning of this manual).
o PASS BATT LIFE > 45 MIN: The last full test of battery passed

BATTERY STATUS: (voltage)

CHARGE STATUS: CHARGING/DISCHARGED/CHARGED/STANDBY/NO BATTERY
An SV-BAT-320 is fully charged when it reaches 12.25 volts. Charging a completely
discharged battery may take up to 4 hours. To conserve your aircraft battery, the
SV-BAT-320 only charges when SkyView detects that your alternator or generator
is running (whenever your engine is running), which is when SkyView’s input
voltage is above 12.25V. Alternatively, connecting a battery charger to your
aircraft battery will also raise the input voltage to a level that will allow SkyView’s
SV-BAT-320 to charge.
The SV-BAT-320 must only be charged by SkyView. External charging of the battery
is not supported. External charging of the battery can damage it or cause it to
explode.
Initial/Recurrent Backup Battery Test
Perform this test to ensure each backup battery in the SkyView system is fully functional upon
initial installation and yearly thereafter. SkyView records the date of the last battery test and
will annunciate, both via a message and by the “needs test” icon in the top bar, when a year has
passed since the last successful battery test.
A fully charged SV-BAT-320 should power a SkyView system for at least 60 minutes if primary
power is lost. As your backup battery ages, the length of time that it can keep a SkyView display
