When it comes to emergency lighting, performance and sustainability aren’t just features—they’re essentials. At BrighterLighting, we equip our emergency lighting systems with state-of-the-artLithium-ion (Li-ion) batteries, setting a higher standard for energyefficiency, reliability, and environmental responsibility.

This blog explores why Li-ion technology leads the market, how it compares to other battery types like Nickel-Metal Hydride (NiMH)and Nickel-Cadmium (NiCd), and what that means for your business.

🔋 Why Li-ion Technology?

Our emergency lights harness the advanced capabilities of Li-ion batteries, delivering:

  • High     Energy Density
        → More power packed into a compact, lightweight design (~250 Wh/kg),     perfect for space-saving emergency fittings.
  • Long     Cycle Life
        → Thousands of charge/discharge cycles with consistent performance over     time—ideal for long-term safety infrastructure.
  • No     Memory Effect
        → Li-ion batteries maintain full capacity regardless of partial charging,     unlike older batteries that degrade with frequent recharges.
  • Low     Maintenance
        → No need for scheduled full discharges, saving time and labour costs.
  • Lower     Environmental Impact
        → With fewer toxic elements and greater recyclability, Li-ion is a     responsible, eco-friendly choice.
  • ⚖️ Battery Technology Comparison

    🔶 NiMH – A Moderate Option

    NiMH (Nickel-Metal Hydride) batteries are still used in some applications, but come with trade-offs:

    • Moderate energy density
    • Acceptable cycle life
    • Some memory effect may reduce long-term efficiency
    • Moderate maintenance requirements (occasional full discharges)

    While NiMH performs better than NiCd, it doesn’t match the performance or sustainability of Li-ion.

    🔴 NiCd – Outdated & Les Sustainable

    NiCd (Nickel-Cadmium) batteries are now widely considered outdated due to:

    • Low     energy density
    • Limited     cycle life
    • Significant     memory effect that shortens performance over time
    • Contains     toxic materials like cadmium, posing environmental and disposal     challenges

    For modern, eco-conscious facilities, NiCd is no longer avaiable long-term solution.
