Battery Backup Power Policy

Important Information Regarding Your Phone Service

Your RiverNet Connect provided telephone Optical Network Terminal (ONT) is powered by plugging it into an electrical wall outlet. In the event of an electrical outage, your ONT will not receive power, just like any other electrically powered device in your home or business. If this were to happen your telephone service, including any medical or security alert services, like E911, will not be available to you.

A backup battery is designed to provide temporary power to the phone ONT in the event electrical power in your home or business is lost. The length of time that your phone will be available during a power outage depends on many variables, including, but not limited to, the following: (i) whether a backup battery remains properly installed in the phone ONT; (ii) whether a backup battery is properly charged; (iii) the condition and age of a backup battery; and (iv) the amount of phone usage when the phone ONT is utilizing power from a backup battery.

It is your responsibility to provide, maintain, monitor, and/or replace a backup battery.

TAKE NOTE: If you have a medical alert system, or security equipment, you are strongly encouraged to utilize and maintain a battery backup. Our telephone service is designed to be used on the premises in which service is installed. The ONT and router that we install in your home or business is the property of RiverNet Connect; the battery backup is purchased and owned by the consumer. In the event you relocate or disconnect service, you must return the ONT and router to the RiverNet Connect office or arrange to have it picked up. If the unit/equipment is not returned, you will be subject to a one-time equipment charge. You assume the risk of loss, theft, or damage to the equipment at all times prior to the removal of the units by RiverNet Connect or return of the units by you.

You may purchase a backup battery as part of your Telephone Service installation. All backup battery packs are purchased from a third-party vendor. Please contact Customer Service at 843-675-3200 option 2 to learn more about the backup battery policy. RiverNet Connect does not guarantee the performance of any backup battery.

The RiverNet Connect installed Optical Network Terminal (ONT) includes a Battery Back Unit (BBU) option, which you may utilize by maintaining an active 12-volt battery in the BBU. With a fully-charged battery, the BBU will provide backup power for your basic voice services, including Emergency 911 dialing, for up to twenty-four (24) hours in the event of a commercial power failure. You are responsible for purchasing and/or replacing the battery in the BBU. We recommend you think about this battery check and replacement just like you would the batteries in your smoke detectors or emergency flashlights.

The BBU is installed at your location in an area where it can be easily monitored. The BBU is connected directly to the ONT to provide backup power if it’s needed. In addition, the BBU contains a series of indicator lights that tell you whether your service is being powered by your location’s electricity or the battery if one is installed. The BBU also indicates when the 12-volt battery needs to be replaced.

Battery Backup FAQ

Your RiverNet Connect provided telephone Optical Network Terminal (ONT) requires electricity to work. If the power goes out, you will be unable to use your home phone service (including making 911 calls) unless you have a Battery Backup Unit.

If you have a need to call 911 when the power is out, or have a home alarm system, or medical alert system, you may want a battery backup unit. Check with your alarm service provider to see if their alarm system requires a voice line to work.

The cost of the battery is $285. If you purchase the battery at the time of the initial installation, the installation fee is waived. A $50.00 fee will be charged for any installation after the initial telephone service install.

You do. RiverNet Connect is not responsible for maintenance, monitoring, or disposal of battery backup units.

When fully charged, our current Battery Backup Unit powers phone service for up to 24 hours during a power outage, letting you make and receive calls from a corded phone. Regarding “shelf life”, an unused battery should last 3-5 years before needing to be replaced. RiverNet Connect is not responsible for maintenance, monitoring, or disposal of battery backup units.

Alternative sources of backup power may be available from other sources, including generators. A charged cell phone may provide the backup phone service needed if home phone service goes out.

Yes. RiverNet Connect will not install it – but if you are comfortable, you can install your own battery. Keep in mind if the wiring is damaged by you during this process and RiverNet Connect needs to correct it, normal service charges will apply.


Voice service only. The battery backup unit only powers customer’s RiverNet Connects phone service, which will only work with a corded phone. The battery backup unit will NOT power a cordless phone, Internet, or TV service. Although it will NOT power a home-monitoring or medical-alert system, a battery backup unit will support the calling service needed to transmit data to those systems.

A red light will display on the battery to let you know the battery is no longer working. Some older batteries may also have an audible alarm. If a battery backup unit is purchased, RiverNet Connect supplies the initial battery for it. Subsequent batteries, their disposal, as well as maintenance and monitoring of the unit are the customer’s responsibility.

To order a battery backup unit call 843.675.3200 option 2.
