In recent years, the advancements in battery technology have been revolutionary in various sectors. As one of the most critical components of emergency lighting systems, choosing the right battery can make all the difference. In this blog, we will discuss the advantages of LiFePO4 (Lithium Iron Phosphate) batteries over NiCD (Nickel Cadmium) batteries for emergency lighting applications.

Enhanced Performance and Emergency Density

LiFePO4 batteries offer superior performance and higher energy density compared to NiCD counterparts. This means that LiFePO4 cells can hold more energy within a smaller space, making them the ultimate choice for compact and powerful emergency lighting systems.

Environmentally Friendly

In comparison to NiCD batteries which contain toxic heavy metals, such as cadmium. Cadmium is harmful to both humans and the environment when improperly disposed of. LiFePO4 batteries are an eco-friendly alternative thanks to their non-toxic chemistry.

Enhanced Safety

LiFePO4 batteries boast superior thermal stability as well as chemical stability in comparison with other lithium-ion chemistries. This makes them a safer option for emergency lighting systems where safety is of paramount importance. In contrast, NiCD batteries have a higher risk of overheating and thermal runaway, making LiFePO4 a safer choice.

Reduced Self-Discharge Rate

One of the major concerns with any battery-operated device is the self-discharge rate. However, with LiFePO4 batteries, you need not worry because they have a much lower self-discharge rate compared to NiCD batteries. This means that LiFePO4 batteries can store energy for longer periods without losing charge. This makes them perfect for emergency lighting applications where lengthy power outages may occur.


When it comes to emergency lighting applications, LiFePO4 batteries clearly outshine NiCD batteries in various aspects, including performance, life cycle, safety, and environmental impact. As a result, choosing LiFePO4 batteries for your emergency lighting systems can enhance their efficiency and reliability while also contributing to a sustainable future.
