Case 1: PKCell High-Temperature Ni-MH Battery Pack for High Temperature Emergency Lighting
Background / Challenge
Emergency and safety lighting systems require a power source that is highly reliable, especially under challenging environmental conditions. Many conventional batteries degrade rapidly when exposed to high temperatures, such as those found in tropical climates, outdoor industrial settings, or enclosed commercial spaces. Key challenges for the battery in this application include:
- High-Temperature Performance: The battery must operate stably in extreme environments, potentially up to 70∘C , often encountered in humid tropical climates or prolonged outdoor exposure.
- Guaranteed Reliability: As the backup power for critical safety systems (e.g., exit signs, hallway lighting), the battery must ensure a continuous power supply during blackouts or natural disasters like floods.
- Cost-Efficiency: A long operational life is required to minimize replacement cycles and overall long-term usage costs.
Solution
PKCELL provided the 3.6V High-Temperature Ni-MH Battery Pack (AA 1800mAh) to meet the rigorous demands of emergency lighting and backup power applications. This battery is specifically engineered to maintain peak performance even under thermal stress. Key features of the solution:
- Exceptional High-Temperature Resistance: The battery is designed to operate stably in environments with temperatures up to 70∘C.
- Optimized for Emergency Use: It outperforms standard batteries, guaranteeing continuous power for emergency lights during critical situations such as blackouts.
- Long-Life Durability: The pack supports 500+ charge/discharge cycles, providing a reliable and cost-effective long-term solution.

Case 2: PKCell Ni-MH Battery Pack for Hotel Emergency Downlighting
Background / Challenge
A customer needed a solution capable of delivering 8–12 hours of continuous power and operating reliably in harsh environments for her hotel emergency downlights.
Traditional solutions like lead-acid batteries face several issues:
- Short runtime, typically around 5 hours
- Frequent maintenance requirements (every 6 months)
- Poor performance under low-temperature or high-humidity conditions
- Long charging time with standard 0.5C rates, often taking 5 hours
Solution
PKCELL provided a 12V AA2500mAh Ni-MH battery pack engineered specifically for emergency lighting systems.
Key features of the solution include:
- Extended Runtime Assurance: 2500mAh high capacity ensures 8–12 hours of continuous illumination, far exceeding the industry average of 5 hours.
- Extreme Environment Adaptability: Operational range from –20°C to +60°C, making it ideal for basements, tunnels, outdoor installations, and humidity-prone environments.
- Maintenance-Free Safety: Ni-MH chemistry with no memory effect and 2-year replacement-free performance—avoiding the frequent maintenance required by lead-acid batteries.
- Rapid Charging: Supports 1C fast charging, enabling full charge in 2.5 hours (compared to 5 hours for typical 0.5C competitors).
Why PKCELL?
- Reliable High-Capacity Ni-MH Technology: Long runtime, leak-proof design, and stable discharge performance for public safety environments.
- Strong Adaptation to Harsh Conditions: Proven operation in cold-start scenarios, high-humidity tunnels, vibration-prone subway systems, and industrial risk zones.
- Fast Charging & Long Cycle Life: 1C charging and 500+ deep cycles support demanding commercial and hotel compliance testing.
- Low-Maintenance, Safety-Focused Design: No memory effect and extended replacement-free lifespan reduce operational costs.
- Versatile Application Support: From emergency exit signs to smart IoT-linked lighting systems, PKCELL provides solutions that meet both traditional and emerging emergency lighting needs.
