SV-BAT-320 Backup Battery Installation
9-6 SkyView System Installation Guide - Revision AA
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 Initial SV-BAT-320 Test below.
TEST RESULT:
o FAIL: VOLTAGE DROP TOO HIGH: Battery likely needs to be replaced. Contact Dynon
Avionics Technical Support (contact information at the beginning of this manual).
o FAIL: LASTED xx MINS: Battery likely needs to be replaced. Contact Dynon Avionics
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 SV-BAT-320 Test
Figure 101 – BATTERY TEST NEEDED Message
The Initial SV-BAT-320 Test is performed to ensure that a SV-BAT-320 is fully functional after
installation is complete. SkyView records the date of the last battery test (if any) and will
annunciate, via a message and an icon in the top bar, when an initial, or annual battery test is
required. For instructions on performing the annual SV-BAT-320 test, see Appendix A:
Maintenance and Troubleshooting, Instructions for Continued Airworthiness, Annual SV-BAT-
320 Test.
An SV-BAT-320 is designed to (when fully charged) power a SkyView display and devices
powered by a SkyView display (see System Planning, Power for details), for at least 60 minutes
if aircraft power is lost. The Initial SV-BAT-320 Test ensures that an SV-BAT-320 has adequate
capacity by discharging it while recording the time elapsed.
