Frequently Asked Questions

 

Lebanon customers, please click here for specific instructions and frequently asked questions.
 

What is a Battery Backup Unit (BBU)?

A Battery Backup Unit (BBU) is a power source that provides power for your Cincinnati Bell voice service, including Emergency 911 dialing (depending upon your specific device) in the event of a power outage.
 
How does Cincinnati Bell Telephone’s Battery Back-up unit (BBU) work?

Fioptics (Fiber to the Home) service requires an Optical Network Terminal (ONT) that uses electrical power. The ONT is a media converter that is installed by Cincinnati Bell during your Fioptics installation. The ONT that is installed will convert fiber-optic light signals to copper/electric signals to deliver you phone, Internet and TV service. If the ONT loses electrical power, as in the case of an electrical power outage, service will be in-operable. The ONT is capable of battery backup that can power only voice service for up to 8 hours or 24 hours, depending on the battery backup product purchased).

If purchased, a Cincinnati Bell Technician will install a BBU with a battery inside wired in close proximity to the ONT. ONT installation locations vary depending on customer requirements and home layout but are generally located in basements, garages, or other areas of the home.

 
Why would a Fioptics (Fiber to the Home only) customer want a battery back-up (BBU) solution?

If you rely on your home phone as your primary means of reaching 911 emergency services you should consider back-up. Customers who rely on home phone service to ‘always’ work may want to consider adding a battery option keep these devices operational during an electrical power outage. It is important to keep in mind, however, that the battery will not power cordless phone handsets since they require power directly from an electrical outlet.

 
How long will the battery backup home phone service?

Depending on what BBU is purchased, the battery will last either 8 or 24 hours. The 8 or 24 hours is stand-by time, meaning if you make a phone call while the battery is in use, depending on the length of the call(s), age of the battery, number of power outages, and other factors, it might last less than 8 or 24 hours. Cincinnati Bell recommends a customer only make emergency calls during a power outage.
 
What does Cincinnati Bell charge for Battery Backup (BBU)?

Cincinnati Bell charges a one-time fee of $99.99 (8-hour) or $249.99 (24-hour). The BBU solution is installed during initial service installation. This includes installation of the BBU and includes the battery (or multiple batteries for the 24-hour BBU). For the 8-hour battery, a $99.99 charge will apply if Cincinnati Bell comes out to replace a battery. For the 24-hour battery, a $179.99 charge will apply if Cincinnati Bell comes out to replace the batteries.
Is there a warranty on the battery if it is installed by Cincinnati Bell?

Yes. If Cincinnati Bell installed the battery there is a one-year warranty covering parts and labor. For repair, can call (513) 566-4101.
 
How can I buy a replacement battery?

You can purchase a replacement battery from either Cincinnati Bell or a third party vendor (Retail examples would be Batteries Plus or AutoZone. Online would be Amazon). For the 8-hour battery, a $99.99 charge will apply if Cincinnati Bell comes out to replace a battery. For the 24-hour battery, a $179.99 charge will apply if Cincinnati Bell comes out to replace the batteries.
 
 
How do I properly dispose of my old battery?

Battery disposal standards and requirements vary by state. When replacing your battery, please make sure to dispose of your old battery properly. For information on properly disposal of batteries, you may visit www.ehso.com/ehshome/batteries.php or call the EPA at 1-202-272-0167. Your local municipality may also have information about proper disposal of batteries.

For more information about recycling, you can contact Call2Recycle at 1.877.RECYCLE (1.877.273.2925) or visit call2recycle.org to find a list of the drop-off locations closest to you.
 
Are there any special precautions I should take when handling a backup battery? 

Yes, below are standard precautions when handling a backup battery:
  • Do not lay any type of metal object on or across the battery terminals as this will short the battery and create a risk of explosion.
  • Store batteries in a cool dry place (40°F to 90°F)
  • Transport batteries with the terminals protected and insulated from contact with other metallic materials.
  • Keep batteries out of reach of children.
  • Never smoke or have open flame near a battery.
  • Wear protective eyewear when working with batteries.
  • If the case of the battery gets cracked or broken, handle with gloves, place in a heavy-duty plastic zip-lock bag and dispose of immediately at a recycling location. Do not keep a damaged battery in your home or store in your vehicle. Transport immediately.
  • Do not get the battery wet, keep dry.
  • Battery may explode if charged inappropriately or used in equipment for which it was not intended.
  • Batteries giving off a rotten-egg smell should be disconnected immediately and disposed of at a recycling location. Handle with gloves if any fluid is present.
  • Batteries that are hot (above 120°F) should be disconnected immediately. Have the Battery Backup unit checked for proper operation and dispose of the battery accordingly. Handle with gloves.
How will I know my battery needs to be replace and how do I replace it myself?

Under normal conditions, the batteries used in the Fioptics BBU have a lifespan of about 3 – 5 years. A light on the BBU will illuminate when the battery needs to be replaced. On some models, an audible alarm (similar to the alarm on a smoke detector) will also notify you when the battery needs to be replaced.

In all Cincinnati Bell areas except Lebanon (Lebanon customers – please see the section below specific to the BBU for your service), the battery model used in the BBU is a standard GS Goldtop GT12080-HG. This is a 12 volt 8Ah alarm battery with standard .25 tab connecting terminals. A replacement can be found on such shopping sites as eBay and Amazon and at several local retailers like Battery & Bulbs. By doing a simple web search for a “GT12080-HG” battery, a search engine should return several batteries from different manufacturers ranging in price from $11.00 up to $40.00. Cincinnati Bell recommends using the GS Goldtop GT12080-HG.

The following do it yourself guides list the steps involved in changing the battery in the BBU. First, identify the type of unit installed at your premises from the choices below and then follow the instructions.

Cincinnati Bell utilizes three different manufacturers for its BBU: Delta, CyberPower, and Alpha (outdoor unit).

(If you are in an apartment or condo complex, a BBU solution was most likely already installed supporting multiple units in a utility closet or outside of the complex. If you find that during a power outage you no longer have voice service and require a battery change, you will have to call Cincinnati Bell as there is no way for a tenant/condo owner to do it themselves due to the inability to tell which battery backs up which apartment/condo. This may require a landlord to call. There is a mandatory $99.99 charge for this visit if you have the 8-hour BBU and a mandatory $179.99 charge if you have the 24-hour BBU. Remember, cordless phones will not work no matter if a BBU is installed or not.)

DELTA

When the battery goes bad on the backup device, a Replace Battery light illuminates.
 


Open the battery compartment cover on the battery backup device. Depress the small textured area on the bottom of the lid while pulling it away from the housing.
