How do I determine when to replace the battery back-up in the SBV3202 Modem?
The SBV3202 includes a battery back-up feature for XFINITY Voice service subscribers.  The battery is optional and can be purchased at  The battery back-up will allow the voice service to function in case of a power outage, but is not intended to replace the AC power for an extended period of time.  The available talk time can last up to 5 hours or provide 8 hours in standby time.  

The battery back-up status can be verified by accessing the SBV3202 Web Manager.  The battery back-up will perform an initial test charge when a battery is installed.  The Battery Operational Status will display BATTERY REPLACE when the installed battery back-up needs to be replaced.  TELEMETRY NORMAL is displayed when the battery back-up is functioning.  This document describes the step to determine if the battery back-up needs replacement.​
