Power loss in an emergency can be risky. Battery backup reliability is required in the most unexpected situations to help deliver visibility even in the most dire situations.

When loss of power creates a blackout, people can be easily panicked. Emergency lighting illuminates the path to exit, helping avoid a disastrous situation. But since emergency lighting signs have also lost power, it’s vital that a reliable battery backup system is in place to keep them operating.

These systems depend on reliable standby power to support peoples' safety and keep systems secure. With batteries designed and manufactured by EnerSys®, you can be confident that you'll have the power you need in critical situations.

With emergency lighting, batteries are the last line of defense during a power outage. We offer a variety of plug and play, virtually maintenance-free, sealed VRLA batteries. They are designed with fast recharge for repeat duty and high energy density to fit small areas. They are extremely reliable allowing you to install them with confidence. 

We offer a host of battery options to match various emergency lighting applications:

  • PowerSafe® SBS & SBS EON batteries provide fast charge for repeat duty cycle
  • Genesis® EP & NP batteries are virtually maintenance-free VRLA solutions that offer high energy density for space-constrained battery installations
  • Cyclon® series are pure lead batteries that can operate in extreme temperatures

All EnerSys battery solutions are designed to be low maintenance and non-hazardous, with low levels of gassing for sensitive installations.



As the world leader in stored energy solutions, EnerSys® provides integrated systems and services for many types of markets and industries.
