EPB Fi Phone: Battery Backup

Important information to note

Any EPB residential phone service can receive backup power.

EPB offers backup power solutions for phone customers available at time of purchase, whether this is creating a new account or adding phone lines to existing service.

In the event of a power outage:

Customers with EPB phone service cannot make or receive calls, including 911 calls, without a battery backup. EPB’s Battery Backup service provides up to 24 hours of phone service during a power outage.

EPB lets you add battery backup to your phone at time of purchase:

Whether that’s starting a new account or adding phone service to your existing fiber account. Batteries can be leased as a managed service for $20 a month, which includes replacements for malfunctioning or defunct batteries, or purchased for a one-time fee of $450. Purchased batteries do not include monitoring, maintenance, or replacement. Customers can purchase a replacement battery online or by contacting our customer service department.
