Battery Back-Up

For many years, phone service would allow people to stay connected to emergency contact centers during a power outage. However, many of today’s advanced phone services require backup battery power to continue functioning when electricity goes out. Without a backup battery or alternate backup source such as a generator, residents would not be able to make any calls, including emergency calls to 911.

So, to avoid a disruption of phone service during a power outage, we are making available a 24-hour backup battery. The cost of the battery and the accompanying Y cable is $269 plus installation. FTC makes these available because we believe having a source of backup power is just that important.

Your purchase includes 24 hours of standby time and a five-year warranty form the manufacturer, Precision Battery, on the battery and power supply. The company states, however, that the design life is 10 years. Further, it says the storage temperature should be between -22 degrees F to 149 degrees F.

As with any battery, monitoring its condition is important so when the unit is needed, it is operating at full strength. We recommend checking the “visual indicators,” located on the side of the battery, at least twice a year.

Two of the visual indicators that are vitally important are “low battery” and “replace battery.” When the DC indicator flashes, the battery is low. This signifies the unit “has reached equal to or less than 45% remaining capacity on battery discharge.” When the Battery indicator illuminates red, the battery needs to be replaced.
