7.2V Ni-MH Ni-Cd Battery for Flashlight Exit LED Emergency Lighting Battery Backup Replace 3+3KRHT23/43-1,5 or L-HB500-0-1

Product Overview

The FMA 7.2V Ni-MH / Ni-Cd Rechargeable Battery Pack is a reliable, high-endurance backup power solution engineered specifically for stairwell lights, staircase emergency fixtures, exit signs, and commercial LED emergency lighting units. Assembled from premium Sub-C (SC) high-temperature emergency cells in a 6S series configuration (3+3 stick layout, 25 × 132 mm per stick), this pack is designed as a direct drop-in replacement for worn-out OEM emergency batteries, including 3+3KRHT23/43-1,5 and L-HB500-0-1.

Available in both Ni-Cd (1200mAh to 1800mAh) and Ni-MH (2200mAh to 3000mAh) chemistries, allowing facility managers and electrical technicians to select the optimal balance between budget, wide operating temperatures, and extended runtime duration.

Technical Specifications

Choosing the Right Chemistry & Capacity

• Ni-Cd (1200mAh / 1500mAh / 1800mAh): Proven emergency lighting chemistry with superior continuous trickle-charge resilience and broad operating temperature range (−20°C to +60°C). Ideal for standard commercial buildings, industrial corridors, and cold stairwells.
• Ni-MH (2200mAh / 3000mAh): Higher energy density offering extended 90-minute or 3-hour emergency backup runtimes without memory effect. An eco-friendly upgrade for fixtures requiring maximum duration.

Key Features

• Purpose-Built for Emergency Backups: Designed for continuous float/trickle charging in always-on emergency lighting and illuminated exit fixtures.
• High-Temperature Sub-C Cells: Engineered to withstand the elevated ambient temperatures found inside enclosed lighting fixtures.
• 3+3 Stick Configuration: Perfectly fits elongated battery compartments in architectural emergency luminaires and exit boxes.
• Direct OEM Replacement: Seamlessly replaces 3+3KRHT23/43-1,5, L-HB500-0-1, and standard 7.2V emergency lighting sticks.
• Economical Building Maintenance: Restores safety lighting to full building-code compliance without replacing expensive fixtures.

Compatible Applications

• LED exit signs and illuminated directional emergency signage
• Stairwell, corridor, and staircase emergency backup lighting units
• Commercial fire safety lighting and architectural emergency bulkheads
• Industrial standby power units and security corridor illuminators

Connector Customization

Standard wire leads or connectors are shown in the product pictures. If your emergency lighting fixture uses a specific plug (such as AMP, JST, Molex, faston tabs, or customized lead lengths), please contact us before ordering for custom terminal assembly.

Safety Information

• Charging: Use only within fixtures or chargers designed for 7.2V Ni-Cd or Ni-MH battery systems. Do not exceed manufacturer charge specifications.
• Installation: Ensure correct polarity (+ red, − black) during wiring. Disconnect mains power before replacing batteries in fixtures.
• Storage: Store in a cool, dry place (15°C–25°C) away from direct sunlight. Maintain a partial charge (40%–60%) for prolonged storage.
• Operation: Do not short-circuit, crush, puncture, or expose to open flame. Do not immerse in liquids.
• Temperature: Operating range: Ni-Cd −20°C to 60°C; Ni-MH 0°C to 45°C.
• Disposal: Recycle responsibly according to local hazardous battery regulations. Ni-Cd contains cadmium and must never be disposed of in standard municipal trash.
• Inspection: Periodically test emergency illumination duration in accordance with local safety regulations. Replace immediately if swelling, corrosion, or inadequate runtime occurs.
