Understanding Battery Options for Emergency Lighting

When comparing emergency lighting costs, consider the total lifetime cost, including battery maintenance. While some options may seem cheaper initially, frequent replacements due to poor battery performance can increase long-term expenses.

Battery Types for Emergency Lighting

Several battery options are available for emergency lighting, each with its own advantages and drawbacks:

• Central Battery Systems: These powerful systems are typically used in large buildings and require specialized installation and maintenance.
• Lead-Acid Batteries: A cost-effective option, but they have a shorter lifespan and higher self-discharge rate compared to other options.
• Nickel Metal Hydride (Ni-MH) Batteries: Offer a good balance between cost and performance, but their lifespan and discharge rate fall short of Lithium batteries.
• Nickel-Cadmium (Ni-Cd) Batteries: A mature technology known for durability, but Ni-Cd batteries have environmental concerns due to their cadmium content and are being phased out in some regions.
• Lithium Batteries: Offer superior performance with high energy density, long lifespan, and fast charging capabilities. However, they can be a more expensive option upfront.

Epowertech's Focus on Lithium Iron Phosphate (LiFePO4) Batteries

Epowertech prioritizes LiFePO4 batteries in its emergency lighting solutions due to their numerous advantages:

• Energy Efficiency: LiFePO4 batteries boast double the energy density of Ni-MH and triple that of Ni-Cd, requiring a smaller physical size.
• Reduced Maintenance: The slow self-discharge rate (3-5% per month) minimizes charger activity compared to Ni-MH/ Ni-Cd batteries, reducing energy consumption and maintenance needs.
• Extended Lifespan: LiFePO4 batteries support fast charging and offer a significantly longer lifespan (2000 cycles) compared to Ni-MH/Ni-Cd (500 cycles).
• High-Temperature Performance: LiFePO4 batteries tolerate higher ambient temperatures (up to 60°C) compared to Ni-MH (50°C) and Ni-Cd (55°C).
• Environmentally Friendly: LiFePO4 batteries are a more sustainable choice compared to Ni-Cd batteries, which contain harmful heavy metals like cadmium.

By prioritizing LiFePO4 batteries, Epowertech provides emergency lighting solutions that are cost-effective in the long run, require minimal maintenance, and contribute to a greener environment.
