Keeping your modem powered during a power outage
When your modem is plugged into the battery backup, the battery will automatically become your modem’s power source during a power outage, keeping you connected to the Internet.
If your Home phone service utilizes a cordless handset, you cordless phone will be powered by the battery in the phone. If you wish to continue charging your cordless phone, you must plug the handset into the battery backup.
How long will a battery backup provide power?
Assuming the battery backup is only used to power your modem, the battery will typically last about two to eight hours, depending on its capacity (measured in VA). However, the actual length of time the battery backup can power your modem depends on various factors. See the battery manufacturer’s website for details.
To maximize the efficiency of your battery backup, we recommend only connecting your Bell modem to it.
