How do I change my Battery on my Battery Back-Up (BBU) Device?
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. For a $99.99 fee, Cincinnati Bell can schedule an appointment (call 513-566-4101) to have one of our expert service technicians replace the battery. However, customers can change the battery themselves and save the cost of the service call.
The battery model used in the BBU is a standard GS Portalac PX12072 or the GS Goldtop GT12080-HG. This is a 12 volt 7Ah 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 “PX12072” battery, a search engine should return several batteries from different manufacturers ranging in price from $11.00 up to $40.00. CBT recommends using the GS Portalac PX12072 or the GS Goldtop GT12080-HG.
The following DIY guide lists 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 Telephone 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 Telephone 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. Remember, cordless phones will not work no matter if a Battery Back Up is installed or not.)
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.
Next, release the hook-n-loop strap. Be careful to make sure the battery doesn’t fall out! The battery is heavy and can cause damage or injury if it falls out.
Grasping the battery with one hand, carefully remove the red and black wires from the battery terminals by pulling firmly on them with your other hand.
When the battery is disconnected, the Missing Battery light illuminates.
Holding the new battery, reconnect the red and black wires. The battery terminals are color coded, so just match the red wire to the red terminal and the black wire to the black terminal.
Carefully place the battery back inside the enclosure and replace the hook-n-loop strap.
Finally, replace the battery compartment cover. The Missing Battery and Replace Battery lights should now go out within 15 minutes.
Locate the CyberPower battery backup unit. It is generally located within 6 feet of the ONT within the interior of the home.The battery light will be RED when the battery is missing or needs to be replaced.
Depress the recessed tab on the backside of the backup, and begin sliding the access cover downward, to remove cover.
Continue to slide the access cover until it is completely separated from the battery backup housing.
Slide the battery partially out of the battery backup enclosure and disconnect the red and black battery connection wires. Remove the old battery completely from the housing.
To install the new battery, partially slide the battery into the housing, make sure to connect the red (+) and black (-) battery terminal wires to the red and black marked tabs of the battery.
With the battery terminal wires connected, slide the battery fully into the housing oriented as shown.
With the new battery fully inserted into the housing, replace the access cover and slide up, until the cover clicks into place. The RED battery light will go out within 15 minutes.
In rare occasions, Cincinnati Bell might have installed your ONT and thus your Battery Back UP unit on the outside of your home. The Alpha Battery Back-Up Unit is an indoor/outdoor unit able to withstand weather elements. Thus, with the Alpha, in order to view the red indicator light showing a ‘dead’ battery, the cover of the Battery Back Up unit must be removed first.
Locate the Alpha Flexpoint BBPS (Batter Backup Power Supply). It is generally located within 10 feet of the ONT location, and may be either inside the home or on the exterior.
Locate the screw located in the lower right hand corner of the battery access cover. Using a Phillips head screwdriver, turn the screw counter-clockwise to completely loosen the screw. Open the battery access cover by grasping the cover near the screw and open towards the hinges on the left hand side.Inside the RED led light will be on solid to indicate a bad battery, or blinking to indicate a low battery.
Loosen the hook and loop fastener by gently pulling it loose from the right side, and then pass the loose end through the plastic loop.
With the battery removed from the enclosure, gently pull the black and red connectors away from the battery terminals to disconnect the battery.
To re-connect a new battery, slide the connector attached to the black wire onto the black(-) battery terminal, and slide the connector attached to the red wire onto the red (+) battery terminal.
Insert the battery into the housing, with the terminal connections placed up and to the right side of the enclosure (as shown in the picture above). Pass the end of the hoop and loop fastener through the plastic loop, and pull the fastener tight. Attach the hook and loop fastener by pressing it tightly together.
Close the door of the battery backup enclosure, and secure by turning the screw in a clockwise direction until tightened. Be sure rubber door seal is in place if your unit is outside.
