A fully charged SV-BAT-320 should power a typical SkyView system for at least 60minutes if primary power is lost.If the SkyView system has more than one display with a backup battery installed, perform thetest for each display individually. Power off all but one display during the test.15-6 SkyView System Installation Guide - Revision J
