A backup battery can be purchased to insert into your XFINITY Voice modem to provide additional hours of service during a power outage. (Backup batteries are not available for purchase from Comcast by Unlimited Select customers.)
Unlimited Select customers, please see information provided below.
In the event of an emergency, a backup battery can support your service for several hours so your phone and alarm system should remain fully operational for up to 8 hours. To purchase an XFINITY Voice backup battery, call 1-888-972-1261. If you have a home security system, please contact your home security provider prior to your XFINITY Voice service installation so you can arrange a compatibility test.
Note: If you lose your power due to severe weather, Comcast can not support priority consideration of "restoration of service" requests to service locations using in-home medical monitoring equipment such as oxygen or heart monitors.
Unlimited Select Customers: If there is an electrical power outage to the Comcast network in your area, your Unlimited Select will cease to operate during the outage, preventing inbound or outbound communications to or from systems or devices connected to Unlimited Select, including, but not limited to, home alarm or home security systems, medical monitoring devices, personal emergency alert devices or home detention devices.
