Power Your Phones When the Electricity Goes Out
With a Battery Backup Unit from TDS
Some TDS Phone service is power dependent, which means it doesn’t work when the electricity goes out; preventing you from being able to make calls (including 911 emergency calls).
To ensure your home phone service works at all times, you can get a Battery Backup Unit. Available as an add-on for a one-time fee, a Battery Backup Unit supplies up to 24 hours of back-up power (when it’s fully charged) to your phone service. This enables you to make and receive phone calls with a corded phone, like you normally would.
To order your Battery Backup Unit, call 1-888-CALL-TDS.
Who Needs Battery Backup?
Not all customers need a Battery Backup Unit, especially if you have a charged, reliable cell phone. However, a Battery Backup Unit does bring peace of mind to customers and is useful if you have:
- Medical issues that require emergency 911 assistance
- A home medical alert system
- A home monitoring or security system
The Battery Backup unit does not:
- Power any other TDS service (like Internet or TV).
- Power cordless phones. It will only work with a corded, landline phone.
- Power a home-security or health-monitoring system; however it will provide the communication services needed for those systems to transmit data.
How It Works
When your power goes at home, the Battery Backup Unit automatically kicks-in, as signaled by an audible alarm. When fully charged, you can expect your Battery Backup Unit to supply up to 24 hours of power to your phone line. However, each phone call you make/receive will deplete the reserve. So, too, will the number of corded phones hooked up to the backup.
Recommendation: To preserve your power, only make emergency 911 calls when your Battery Backup Unit is working. But, do not turn off the Unit to save the battery as it could prevent the receipt of emergency calls.
