“Does this cable modem have a backup battery capability in case of a power outage for the phone line?”

1-4 of 4 Answers

• It does not, but why worry about a battery backup for just the modem when you can get a UPS that backs up your modem, pc, monitor, and wifi router at the same time with auto shutdown when you lose power. I recommend the APC 660VA UPS with 6 ports and 1 USB. If that solution doesn't work for you, and you require a modem with battery backup then buy a combination modem/wifi from Arris that does have a battery backup, or another vendor.

  I would recommend:

  • 
    APC - Back-UPS, 600VA/330W, Tower/Wall Mount, 7 Outlets, LED Indicator, USB-A port - Black

• It does not have a battery backup, but you could add an UPS to the system to create your own back-up system.
