Description: Lead-acid batteries are the most prevalent type of emergency lighting battery due to their affordability, long lifespan, and ease of maintenance. They consist of lead plates immersed in an electrolyte solution of sulfuric acid. Cost-Effective: Lead-acid batteries are relatively inexpensive compared to other battery types.
Emergency lighting batteries are designed to provide a reliable source of power for emergency lighting systems during power outages. They are typically connected to a dedicated circuit that is separate from the main power supply.
In the market, there are emergency light products available with different battery technologies. However, the major emergency light battery technologies used in an emergency lighting battery pack are: Nickel-cadmium batteries are rechargeable batteries where the electrodes are nickel oxide hydroxide and metallic cadmium.
Common voltages for emergency lighting batteries include 12 volts and 24 volts. Using a battery with a voltage that is too high or too low can damage the emergency lighting system. Discharge Rate: The discharge rate, measured in C-rate, indicates how quickly the battery can deliver its capacity.
The use of Lithium-ion batteries in emergency lighting products is increasing as they have several advantages over other types of rechargeable batteries. A lithium iron phosphate (LFP) battery is more efficient than a NiCd battery as LFP batteries lose less charge over time and also less energy in the form of heat during their charging process.
Higher Cost: Li-Ion batteries are the most expensive type of emergency lighting battery. Requires Dedicated Charging System: They require a dedicated charging system that is specifically designed for Li-Ion batteries.
