Ensure your Verizon Fios service stays online during power outages with a reliable battery backup system. This guide explains what Fios uses, how it works, and what you can do to maintain essential power for your internet and TV.
Losing internet and TV during a power outage can be a real headache, especially when you rely on Fios for news, entertainment, or even work. Fortunately, Verizon Fios equipment comes with a built-in battery backup system to keep things running. But how does it actually work, and what happens when that battery needs attention? You might be wondering if you need to do anything special to keep your Fios service alive when the lights go out. Don’t worry, setting up and understanding your Fios battery backup is simpler than it sounds. We’ll walk you through everything you need to know, from identifying your battery to knowing when it’s time for a replacement, so you can stay connected.
Understanding Your Verizon Fios Battery Backup
Verizon Fios uses a special box, often called the ONT (Optical Network Terminal), which is the device that brings the internet signal into your home. This ONT needs continuous power to function. During a power outage, the battery backup kicks in automatically, allowing your Fios internet and sometimes your TV service to continue working for a limited time.
What is the ONT?
The ONT is a small white or gray box, usually installed near where the Fios fiber optic cable enters your home. It’s the gateway that converts the light signal from the fiber optic cable into an electrical signal your router can use. It’s a critical piece of equipment that requires a steady power flow.
How Does the Battery Backup Work?
Most Fios installations include a battery backup unit, which is often a larger, black box that connects to the ONT. This backup unit contains a rechargeable battery. When the electricity goes out, the battery instantly takes over, providing power to the ONT. This ensures your internet and phone service (if you have Fios Digital Voice) remain active. The duration it lasts depends on the type of battery and how much power your Fios equipment is using.
Why is it Important?
A working battery backup is essential for several reasons:
- Continuous Connectivity: Stay connected for work, emergencies, or simply to keep up with the news.
- Communication: If you have Fios Digital Voice with phone service through your ONT, the battery backup keeps your landline working, which is crucial during outages when cell towers might be overloaded.
- Peace of Mind: Knowing your essential services will continue during unexpected power interruptions provides significant peace of mind.
Identifying Your Fios Battery Backup Unit
Verizon uses a few different types of backup power systems. The most common one resembles a medium-sized black box situated below or beside your ONT. It typically has indicator lights that can tell you about its status.
Common Battery Backup Models
The most prevalent unit is the “Standby UPS 800.” It’s a black, rectangular unit, usually about the size of a lunchbox. It has a slot where the battery is housed. Other older models might exist, but the principle of operation is the same: providing a temporary power source.
Checking the Lights
Look for lights on the front of the battery backup unit. These lights are your indicators:
- Green Light: Usually means the unit is powered correctly and the battery is charging.
- Yellow/Amber Light: Often indicates a low battery, a problem with the battery, or that the unit is running on battery power.
- Red Light: Typically signifies a critical failure or that the battery needs immediate attention.
- No Lights: Could mean it’s unplugged, the power is out and it’s running, or there’s a more serious issue.
Consult your Verizon Fios equipment manual or Verizon’s support site for the exact meaning of the lights on your specific model. You can often find detailed documentation on Verizon’s support pages by searching for your equipment model number.
Where to Find Your ONT and Battery
The ONT is usually installed near where the Fios fiber line enters your home, often in a basement, garage, utility closet, or even sometimes on an exterior wall (though less common). The battery backup unit is typically located close by, often mounted on the wall beneath the ONT.
How to Test Your Fios Battery Backup
Regularly testing your battery backup ensures it’s ready to go when you need it most. It’s a simple process that can prevent unexpected service disruptions.
Step-by-Step Testing Process
- Locate the Battery Backup Unit: Find the black battery box connected to your ONT.
- Identify the Test Button: Most backup units have a small button labeled “Test” or resembling a power symbol.
- Press and Hold the Test Button: Press and hold this button for a few seconds.
- Observe the Lights: The lights on the unit should change. It might indicate it’s running on battery power. You might hear a faint hum or the ONT’s power light might flicker momentarily as it switches.
- Listen for Alarms: Some units may sound an audible alarm or beep to confirm it’s in test mode.
- Check Service (Optional but Recommended): If possible, briefly disconnect the main power cord from the battery backup unit (not by pulling the wall plug, but the cord going from the battery unit to the ONT). Your internet and phone should continue working. Reconnect the power cord to the ONT. This step simulates a power outage more closely.
- Restore Power: If you unplugged the unit, plug it back in. The unit will begin recharging the battery and will return to normal operation once the battery is sufficiently charged.
What to Expect During a Test
During a test, your Fios services should remain active. The battery backup is designed to seamlessly switch over. You might notice a brief pause in your internet connection, especially if you have a lot of devices active, but it should quickly re-establish. The primary goal is to confirm the battery can power the ONT.
Frequency of Testing
Verizon recommends testing your battery backup unit at least once every six months. This ensures the battery remains in good condition and that the system is functioning as expected.
When to Replace Your Fios Battery
These backup batteries are not designed to last forever. Like all batteries, they have a lifespan and degrade over time. Knowing when to replace yours is key to maintaining reliable backup power.
Battery Lifespan
Most Verizon Fios backup batteries are rated to last between 3 to 5 years. This can vary depending on usage, the number of power outages experienced, and environmental factors like temperature.
Signs Your Battery Needs Replacement
- Aging: If your battery is approaching or has passed the 3-5 year mark, it’s a good candidate for replacement, even if it seems to be working.
- Frequent Alarms: If the unit consistently shows a yellow or red light, or if you hear frequent low-battery alarms, the battery is likely failing.
- Service Interruption During Outages: If you’ve experienced a power outage and your Fios services went down, and you discovered the battery was dead or not working, it’s time for a new one.
- Swollen or Leaking Battery: If you can see any physical signs of damage to the battery itself (bulging sides, leaks), discontinue use immediately and contact Verizon. This indicates a hazardous situation.
How to Get a Replacement Battery
Verizon manages the battery replacement process for their equipment. You generally cannot purchase a compatible battery from a retail store and install it yourself without potentially voiding warranties or causing issues.
- Contact Verizon Support: The best course of action is to call Verizon customer service. They can diagnose the issue remotely or schedule a technician visit.
- Troubleshooting: They will likely guide you through some initial troubleshooting steps, like checking the lights on the unit and performing a test.
- Battery Replacement Program: If they determine your battery needs replacing, they will arrange for a technician to come to your home and swap it out. There might be a fee for the battery and labor, depending on your service agreement and the age of your equipment.
You can find Verizon’s contact information for Fios support on their official Verizon support website.
Understanding Backup Battery Types and Specifications
While you typically get your replacement battery directly from Verizon, understanding the basics of battery technology can be helpful. Fios uses sealed lead-acid (SLA) batteries, which are common in backup power systems.
Sealed Lead-Acid (SLA) Batteries
SLA batteries are a popular choice for uninterruptible power supplies (UPS) like the ones used for Fios. They are relatively inexpensive, reliable, and can deliver high surge currents. They are “sealed” meaning they are maintenance-free and don’t require you to add water.
Key Specifications to Note (for your reference)
| Specification | Description | Relevance to Fios |
|---|---|---|
| Voltage (V) | The electrical potential difference. Fios units typically use 12V batteries. | Must match the voltage requirement of your Fios backup unit. |
| Capacity (Ah – Ampere-hours) | Measures how much energy a battery holds. A higher Ah means longer runtime. | Determines how long your services can last during an outage. Higher Ah is better for longer backups. |
| Dimensions (L x W x H) | Physical size of the battery. | The replacement battery must fit inside the Fios backup unit’s battery compartment. |
| Terminal Type | The type of connectors on the battery (e.g., F1, F2 terminals). | Must be compatible with the wiring harness in your Fios backup unit. |
Why Not Buy Your Own Battery from a Store?
While it might seem tempting to buy a battery from an electronics store to save money, it’s generally not recommended for Fios equipment. Verizon’s backup units are designed to work with specific battery types and voltages. Using an incorrect battery could:
- Damage the Fios backup unit.
- Prevent the new battery from charging correctly.
- Cause the system to malfunction during an outage.
- Void your service agreement or equipment warranty.
It’s always safest to let Verizon provide and install the correct battery.
Troubleshooting Common Battery Backup Issues
Sometimes, despite your best efforts, you might encounter problems with your Fios battery backup. Here are a few common issues and how to approach them.
Issue: Constant Beeping or Alarm
Possible Cause: Low battery, battery failure, or the unit has lost power.
Solution:
- Check if the unit is plugged in and receiving power from the wall.
- Look at the indicator lights on the unit. If they show a problem (yellow, red, no lights), this confirms a power or battery issue.
- Press the “Test” button. If it doesn’t resolve the beeping or continues to indicate a problem, it’s likely time to contact Verizon.
Issue: No Power to ONT, Even with Battery
Possible Cause: Battery is completely dead and has no charge, and mains power is also out. Or, there’s a fault in the ONT itself or the wiring between the battery and the ONT.
Solution:
- Ensure the mains power is actually out, and the Fios battery backup is supposed to be active.
- Visually inspect the battery backup unit and the ONT for any damage.
- Check that the cables connecting the battery unit to the ONT are securely plugged in.
- If the battery is old (over 3-5 years) and showing no signs of life, it’s probably failed. Contact Verizon for a replacement.
Issue: Lights Indicate a Problem, But Battery Seems Okay
Possible Cause: The backup unit itself might be faulty, not just the battery.
Solution:
- Try a hard reset. Unplug the battery backup unit from the wall. Disconnect the battery if it’s easily accessible and safe to do so (only if you are comfortable and the unit is unplugged). Wait a few minutes, then reconnect the battery (if disconnected) and plug the unit back into the wall.
- If the problem persists, especially with solid red or flashing yellow/red lights, it’s time to call Verizon. They have diagnostic tools and can identify if the entire unit needs replacement.
Issue: Internet is Slow or Dropping During Normal Power
Possible Cause: This is less likely to be a battery issue as it relates to runtime during an outage, but a failing battery backup unit could sometimes cause power fluctuations that affect the ONT’s performance. More likely, this indicates a network issue or a problem with your router.
Solution:
- Restart your Fios router and the ONT.
- Check any indicator lights on the ONT and router for error codes.
- If the issue persists, contact Verizon support for network troubleshooting.
For any persistent issues or if you suspect a hazardous battery condition (like swelling or leaking), always err on the side of caution and contact Verizon Fios support immediately. They are equipped to handle these situations safely and effectively. You can find guidance on troubleshooting your Fios equipment on Verizon’s official equipment support page.
Maximizing Your Fios Backup Power
While the Fios battery backup is designed to keep your internet and phone running, it has limitations. Here are some tips to make the most of its runtime during an outage.
Prioritize Your Devices
Your Fios battery backup primarily powers the ONT and potentially your Fios router (if it’s powered by the ONT or a separate Fios power adapter that is connected to the backup). It’s not designed to power your TVs, computers, or other home electronics. During an outage:
- Focus on essential communication: If you have Fios Digital Voice, your landline will work, which is invaluable in emergencies.
- Consider a separate UPS for routers/modems: If you want to ensure your router and modem (if separate) remain powered and don’t rely solely on the ONT’s limited backup, consider purchasing a separate Uninterruptible Power Supply (UPS) for them. These are readily available at electronics stores and can provide much longer runtime for networking equipment.
Conserve Battery Power
If you know an outage is occurring or likely to happen:
- Turn off unnecessary devices: Shut down TVs, gaming consoles, computers, and smart home devices that are not essential. These consume significant power and will drain your battery backup faster (or the power from a separate UPS).
- Limit heavy internet usage: Avoid streaming video, large downloads, or video conferencing if you absolutely need to preserve power for a longer duration.
Understand Runtime Expectations
Verizon typically states that the battery backup can provide power for up to 24 hours for phone service and up to 8 hours for internet service during a power outage. However, these are estimates and depend heavily on:
- Battery Age: Older batteries hold less charge.
- Power Consumption: How many services are active (internet vs. just phone) and how much data is being used.
- Specific Equipment: Different ONT models and router configurations might have slightly different power draw.
What if You Don’t Have a Battery Backup?
In some Fios installations, a battery backup unit might not have been installed, or it might have been removed. If you realize you don’t have one and rely on Fios for phone service, it’s a good idea to get one.
How to Check if You Have One
Look near your ONT. If there isn’t a black box unit connected, you likely don’t have a Fios-provided battery backup. Check your Fios account or your installation paperwork if you are unsure.
Getting a Battery Backup Unit
Contact Verizon Fios customer support. Explain that you need a battery backup unit for your ONT, especially if you have Fios Digital Voice and need your phone to work during outages. They can advise on the availability of the unit for your specific setup and the associated costs. You can typically find support options on the main Verizon support page.
