For many years, your home phone would allow you to stay connected to emergency voice services during a power outage. However, many of today’s advanced home phone services require backup battery power to continue functioning during an electrical outage. To avoid a disruption of home voice service during an outage – and to maintain the ability to connect to 911 emergency services – Twin Valley offers both 8 hour and 24 hour battery backup solutions. If you’re interested in purchasing battery backup for your landline phone, please give our friendly customer service team a call at 800.515.3311 and they can get you a quote for the specific equipment for your needs. 

What Your Battery Can – and Can’t – Do for You

Twin Valley’s backup batteries for telephone modems allow you to continue to use your home voice services during a power outage.  Without a backup battery or alternate backup source such as a generator, you would not be able to make any calls, including emergency calls to 911. The only way to maintain the ability to use your landline phone is by using some form of backup power.

Twin Valley’s backup battery does not provide power to any services other than voice. Home security systems, medical monitoring devices, and other equipment will not run on a phone backup battery.

Expected Backup Power Duration

Backup batteries are expected to last at least eight hours on standby power. Keep in mind, they won’t last the full duration while in use. You may extend your standby power by purchasing a 24-hour battery or additional eight-hour batteries from Twin Valley, through local retailers, or online.  Please contact our customer service team at 800.515.3311 to make sure you have a compatible device.

Battery Backup Power Monitoring

Your backup batteries will eventually need to be replaced.  They typically last around 24 months depending on usage. For battery replacement, please contact Twin Valley Customer Service for pricing and installation.
