    What to do if my SILENT KNIGHT 4820 shows a battery trouble?
    • A
      Amanda SaundersAug 19, 2025
      If your SILENT KNIGHT Network Router displays a battery trouble message, it means the battery voltage is less than 10.2 VDC. You should check the battery voltage. When disconnected from the system, the voltage should be greater than 12 VDC. Remove the battery and measure the charging voltage across the battery leads, which should measure greater than 13 VDC (within the range of 10.0 to 13.8 VDC).

      If your SILENT KNIGHT Network Router indicates no AC power, there are two possible causes: either the AC voltage is less than 102V, or the transformer may be faulty. To resolve this, check the outlet and measure the secondary output for 17-20 VAC.
