Remember when you didn’t have a smartphone on hand, ready to be used in an emergency? Your Verizon FIOS, on the other hand, does.

As a result, they would (and still do) include a Backup Battery Unit (BBU) with their Optical Network Terminal (ONT) to ensure that people could still connect to the internet and make emergency fiber-based calls in the event of a power outage.


The Verizon Fios battery keeping indicates that either the battery is becoming faulty or is failing to function normally, or that the battery backup is in poor condition. Noise is usually ineffective, particularly for children and the elderly.

It can also detract from the normal activities that take place in the home. If you hear your Verizon Fios battery making noise, it is best to fix the problem right away rather than assuming it.

First, determine whether the battery is in good working order, and if not, replace it with a new one that is. You can also use superglue to completely silence the battery.


If the BBU in your Verizon ONT begins to wear out, the ONT will begin to emit a beeping sound every 15 minutes. Even if you never use it, you will have to deal with the beeping noise at some point because the battery will start to wear out after a few years.

The BBU was powerful enough to support emergency calls for those who relied on fiber-based calls to access services such as 911 in the event of a power outage.

As a result, this feature was extremely useful. Despite the fact that, over time, more people stopped relying on their landline for emergency services, Verizon continued to provide the BBU with their ONT.


The FIOS beeping noise, a formerly useful feature, is a disruption to your normal routine. Consider a scenario in which it begins to beep while your baby is sleeping peacefully.

You can stop the beeping noise by replacing the battery, disconnecting it from the unit, or even reconnecting it to trick your device. Some methods, such as replacing the battery, are the simplest to implement and guarantee that the beeping sound stops regardless of how old your unit is.

1. Replace The FiOS Battery: Straightforward Solution To Beeping

When confronted with a beeping noise, most people choose to replace the battery because it requires the least amount of effort. Although you can now request a free battery replacement from Verizon if you have an older system, you used to have to pay for a mandatory battery replacement, which could be quite costly.

You can look at batteries on Amazon if you don’t want to wait for Verizon to ship you the battery or if you have a new model and don’t want to pay $39.99 for a Verizon BBU. Some options are less expensive and can be delivered quickly.

The Verizon FIOS uses a 12-volt, 7.2 Ah sealed lead-acid battery that can last 2 to 4 years depending on the temperature conditions in which your FIOS ONT is stored.

Some options that you can look at are:

  • ExpertPower Rechargeable Sealed Lead Acid Battery (12-volt, 7.2 Ah): This is a good choice because it is inexpensive and efficient. For the time being, you can install this and forget about any problems.
  • GS Battery Premium Replacement for Verizon FIOS (12v, 8 Ah): This option provides a battery replacement that is identical to the one provided by Verizon but at a lower cost.

2. Buy Some Time

Don’t want to buy a BBU right now? Or do you want to stop the beeping while you figure out how to permanently fix the beeping noise?

Here are a few methods that will help you save time. Not all of them will be as effective as others, but they will provide you with relief for a few hours.

3. Silence FiOS Battery: Stop the Beeping

When looking for solutions that do not require much effort, using the silence battery button is your best choice.

Here is what you need to do:

  1. Locate the Silence battery button
  2. Press and hold it for 3 seconds

Once done, the beeping will stop for at least the next 24 hours. Although it is an easy solution, it is only temporary.

4. Disconnecting the FiOS Battery

For some newer models, simply unplugging the battery may be enough to silence the beeping. Although it appears to be simple, it may not always solve the problem, especially if you installed your unit prior to March 2013.

Here’s how to unplug the FiOS battery:

  1. Take the BBU out of the wall outlet.
  2. Remove the red and black plug connectors from the battery by pinching and gently pulling.
  3. Disengage the battery from the retaining clips that are holding it in place and carefully slide it out of the unit.
  4. Set the old battery aside to recycle after disconnecting the battery clips.

Wait a few seconds, and the battery should stop beeping, depending on your FIOS system.

5. Reconnecting the Battery

You can also try reconnecting the battery after a minute or two of being disconnected. This may fool your ONT into thinking you’ve replaced your battery. This method works best when you are confident that your battery is in good condition and does not require replacement.

To reconnect the battery, first disconnect it and then reconnect it.

  1. Reconnect the plug connectors to the battery, with the black connector connected to the negative terminal and the red connector connected to the positive.
  2. Replace the battery and secure it with the retaining clips.
  3. Return the plug connectors to their original positions.
  4. Your device should emit a beep sound, and the light on the unit should turn green.
  5. Replace the battery cover and plug the BBU into a wall outlet.


When landlines were widely used, this feature was built into older models. Verizon recognizes that as smartphones become more common, this feature should be phased out. Verizon has eliminated the need for mandatory battery replacements for FIOS units installed after March 2013.

When the battery is removed from a newer model, the beeping noise quickly stops. There’s no need to be concerned about your device not working because both older and newer generations of Verizon FIOS work properly even without a battery.


While the beeping was annoying, it was a useful feature that demonstrated the importance of having emergency services available at all times. Fortunately, it is relatively simple to ensure that your battery no longer makes the beeping noise by replacing your BBU or purchasing a newer model.

Make sure you only buy a replacement battery when you need one, as these batteries have a shorter shelf life. Hopefully, you now understand how to eliminate the beeping noise from your FIOS unit and why it was occurring in the first place.

You may occasionally experience problems with your Verizon Fios battery making noise. The main reason could be an emergency or a faulty battery.

In such a case, go over the article again and take all of the steps necessary to resolve the problem. If the problem persists, you should seek the assistance of a professional technician.

It is critical to take precautions when using Verizon Fios. For example, to increase the device’s lifespan, service it more frequently. In addition, if there are any issues with the device or the battery, follow the manufacturer’s instructions. Avoid overcharging the battery and protect it from any type of power surge.

Frequently Asked Questions

Why is my Verizon FIOS box beeping?

Our Fios box is beeping every 15 minutes again because the backup battery needs to be replaced. If you get a different result and your Fios installation is as old as mine, you should contact Verizon and request a replacement battery backup unit.

Will Fios function without a backup battery?

As long as your home has power, FIOS internet and phone service will function without a battery in the backup unit. If there was a power outage in your home and the battery backup unit was missing a working battery, your FIOS phone (including Emergency 911) and internet service would be inoperable.

Is Fios backup battery necessary?

The battery is only required as a backup power source for telephone service. If you unplug the BBU from 110V AC and do not have a working battery installed, the ONT will shut down and all FiOS services will be terminated. In your case, you want to unplug the battery from the BBU but leave the BBU plugged into the wall.
