Can exit signs be battery-powered? That’s a question I get asked a lot as a supplier of exit signs. You bet they can, and in fact, battery-powered exit signs are becoming more and more popular these days. In this blog, I’m gonna break down why battery-powered exit signs are a great option, how they work, and what you need to know before buying them. Exit Signs

Let’s start with the advantages of battery-powered exit signs. One of the biggest perks is the flexibility they offer. Unlike hardwired exit signs that need to be connected to the building’s electrical system, battery-powered ones can be installed just about anywhere. You don’t have to worry about finding a nearby power outlet or dealing with complex electrical wiring. This makes them a perfect choice for older buildings where the electrical infrastructure might not be up to par, or for temporary setups like construction sites, trade shows, or pop-up events.
Another major advantage is the reliability during power outages. We’ve all been there – the lights go out, and suddenly, you’re in complete darkness. In an emergency situation, like a fire or a natural disaster, having functioning exit signs is crucial for guiding people to safety. Battery-powered exit signs are designed to kick in automatically when the main power fails. They usually have a backup battery that can keep the sign illuminated for a certain period of time, typically at least 90 minutes. This gives people enough time to evacuate the building safely, even if the power doesn’t come back on right away.
Cost is also a factor to consider. While the initial purchase price of battery-powered exit signs might be a bit higher than hardwired ones, they can save you money in the long run. You don’t have to pay for the installation of electrical wiring, which can be a significant expense, especially in large buildings. Plus, since they don’t rely on the building’s electrical system, you don’t have to worry about any additional electrical costs associated with running the signs.
Now, let’s talk about how battery-powered exit signs work. Most of these signs use LED lights, which are energy-efficient and have a long lifespan. The LED lights are powered by a rechargeable battery, which is constantly being charged when the main power is on. When the power goes out, a sensor in the sign detects the loss of power and switches the sign to battery power. The battery then provides the necessary energy to keep the LED lights illuminated.
The batteries used in these signs are typically sealed lead-acid or lithium-ion batteries. Sealed lead-acid batteries are more common and are relatively inexpensive. They have a decent lifespan, but they do require some maintenance. You need to check the battery’s water level periodically and make sure it’s properly charged. Lithium-ion batteries, on the other hand, are more expensive but have a longer lifespan and require less maintenance. They’re also more lightweight and can be recharged more quickly.
When it comes to choosing a battery-powered exit sign, there are a few things you need to keep in mind. First, make sure the sign meets all the relevant safety standards. In the United States, exit signs are regulated by the National Fire Protection Association (NFPA) and the Occupational Safety and Health Administration (OSHA). These organizations have specific requirements for the brightness, color, and visibility of exit signs. You want to make sure the sign you’re buying complies with these standards to ensure the safety of your building’s occupants.
Another important factor to consider is the battery backup time. As I mentioned earlier, most battery-powered exit signs are required to provide at least 90 minutes of illumination during a power outage. However, some signs offer longer backup times, which can be beneficial in certain situations. For example, if you’re installing the signs in a large building or a building with multiple floors, you might want to choose signs with a longer backup time to give people more time to evacuate.
You also need to think about the type of environment where the signs will be installed. If the signs will be exposed to extreme temperatures, moisture, or other harsh conditions, you’ll need to choose signs that are designed to withstand these elements. Some signs are rated for outdoor use or for use in wet or damp locations, while others are more suitable for indoor use only.
In addition to these factors, you might also want to consider the design and style of the exit signs. There are many different options available, from traditional illuminated signs to more modern and stylish designs. You can choose signs that match the decor of your building or that have a specific look or theme.
So, there you have it – battery-powered exit signs are a great option for many different applications. They offer flexibility, reliability, and cost savings, and they can help ensure the safety of your building’s occupants in an emergency. If you’re in the market for exit signs, I encourage you to consider battery-powered options.
