Replacement of Batteries for Self-Contained Emergency Lighting
Rechargeable batteries , also known as secondary cell batteries, are essential components in emergency lighting systems. Considered consumables, they will eventually reach the end of their usable life. In a self-contained system, these batteries are expected to function for a design life of four years. However, their ability to meet this design life is influenced by various factors such as storage conditions, duration of storage, operational environment, application, and cycling patterns. When should you replace the emergency lighting battery? Replacing the battery becomes necessary when it can no longer meet its rated duration, ensuring ongoing system compliance. At this juncture, a decision must be made: replace just the battery or the entire emergency luminaire. If opting to replace only the battery, it's crucial that the new one matches the specifications of the old one—same chemistry, capacity, voltage, and form factor, with identical charge/discharge ch...
