The Heart of the System - Emergency Light Batteries: “At the core of every emergency light is a battery - the unsung hero that powers illumination during the most crucial times. These batteries are specially designed to be reliable, durable, and ready at a moment’s notice. Feel the peace of mind that comes with batteries you can count on. Our emergency light batteries are engineered for longevity, ensuring that they’re always ready when needed

What are emergency light batteries?

Emergency lights and lighted exit signs are lit using batteries. These batteries are rechargeable to ensure the continued readiness and activity of the emergency lights. Within the emergency light, the hardware also activates the battery and keeps it powered.

There are three types of batteries for emergency lighting

◮ Nickel-cadmium batteries

◮ Nickel-Metal Hydride batteries

◮ Lithium Iron Phosphate batteries

 

Where to use emergency lighting?

Strategically placed emergency lighting isn’t just a good practice; it’s a blueprint for safety. From stairwells to hallways, these lights ensure no corner is left dark when it matters most.

Emergency lighting is activated when there is a power outage or when the usual light source fails. Thus, emergency lighting runs through batteries and is not dependent on the main power source.

Most emergency lighting systems are made from incandescent bulbs, although modern systems have high-intensity light-emitting diode LEDs.

Emergency lighting is often built in high-rise buildings, including apartments, university dormitories, modern businesses and buildings. Emergency lighting provides adequate light for residential hotels, clinics, classrooms, stores and approved buildings.

Codes often require emergency lighting in any open space larger than 60 square meters. A high degree of fear exists in the event of an accident, so it is necessary to light the environment to prevent injury.

Regulations require that emergency lighting will be installed within a horizontal span of 2 meters above the fire or equipment. In some cases emergency lighting is provided to improve the health of personnel working in extremely unsafe environments.


 

How long do emergency light batteries last?

How long do emergency light batteries last? Long enough to never leave you guessing in the dark. With a lifespan that ensures hours of light, you can trust them to shine when you need them.

For all emergency lighting, the battery check button appears as usual. By clicking the check button, the emergency lighting unit changes from AC power to emergency battery power. It allows you to display the remaining battery charge.

According to UL (Underwriters Laboratories), a fully charged battery in good condition can power an emergency light for at least 90 minutes. The UL 924 rating is only available for batteries that meet or conform to UL's stringent inspection procedures.

Some of today's emergency luminaires have a self-check feature that allows the unit to operate monthly and annually. These inspections eliminate the need for maintenance and improve the reliability of emergency lighting.

After a power outage, emergency lights can remain on for up to three hours, ensuring that everyone has enough time to find their way out. When power is turned back on, the lights can be reset so they can start running when needed.

Emergency lighting batteries have a life expectancy of four years, but in some cases they can survive longer than that.

Think of the long hours of protection our batteries provide. With our emergency light batteries, you’re investing in a future where safety is guaranteed, even during the unexpected.

 

How often should emergency light batteries be replaced?

Knowing when to replace emergency light batteries is as simple as marking your calendar. With regular checks and easy maintenance, you’ll never have to worry about being left in the dark

Emergency light owners will follow OSHA guidelines for daily routine maintenance once a month and once a year. If the 90-second or 90-minute emergency alarm check is not satisfactory, the emergency light batteries will need to be replaced.

Fortunately, the required maintenance is both quick and easy, as most new fixtures have a one-click test feature that allows you to read the batteries properly. By clicking this check button, the unit's disconnect circuit will be triggered and the battery will be tripped.

The light does not come on when the battery is dead. It needs to be replaced by the charger.

Easy to check and replace, our batteries ensure that your emergency lighting system is always operational, always safeguarding your premises.

 

In short, replacing emergency light batteries does not require an electrician because you can accomplish this task. Knowing the life span of your emergency light batteries will allow you to comply with the law and be prepared for emergencies before they occur. Remember, it's best to be prepared at all costs.
