Battery-powered exit signs typically last 3-5 years.
The lifespan of a battery-powered exit sign's battery depends on several factors, including the type of battery used (e.g., nickel-cadmium, nickel-metal hydride, lithium-ion), the sign's power consumption (which is determined by the number and type of LEDs and other components), and environmental conditions (e.g., temperature). Generally, you can anticipate a battery life of 3-5 years under normal circumstances. However, signs with advanced power-saving features could last even longer, while those in harsh environments or with higher power consumption may require more frequent battery replacements. Always refer to the manufacturer's specifications for the exact lifespan and recommended replacement schedule for your specific exit sign model. Regular testing and maintenance are crucial to ensure your exit sign's battery is functioning correctly and ready for emergencies. Some signs have a self-diagnostic function which will alert you when the battery is nearing its end-of-life. Ignoring this can lead to the sign failing during a power outage, causing a safety hazard.
