The most common issue is that the battery can't hold enough charge to power the lights for the required 90 minutes, as specified by AS/NZS 2293.2:2018. This article delves into the factors affecting battery life, the evolution of battery technology in emergency lighting, and practical tips for replacing and disposing of batteries.
This requires dedicated emergency lights or battery backup LED drivers in certain fixtures. In many cases, lights that are required to be battery powered will use different circuitry in the event of a power outage. There are two main types of batteries used to power exit signs and emergency lights: Smaller in size. Turn in any direction.
Larger in size. Cannot be deep cycled. Battery life typically ranges between 2-4 years, they are available in different voltages and amperages, and maintenance is relatively quick and simple. Batteries for emergency lighting must be regularly cleaned and tested to ensure they are still operational and the lighting is not dimmed.
The battery backup of the emergency lighting system will depend on the building and the evacuation strategy. A 3-hour duration is required in entertainment places (cinemas, theatres, etc.) and facilities with a sleeping risk (hotels and guesthouses, etc.).
Building managers frequently ask us why their emergency lights fail after just 2-3 years. The most common issue is that the battery can't hold enough charge to power the lights for the required 90 minutes, as specified by AS/NZS 2293.2:2018.
Typically, changing batteries does not require the power to be shut off. As mentioned, batteries don’t always function properly in cold weather or if they get wet. In this instance, an electrician might choose to have an inside fixture’s battery, power and remote head outside, for example.
