Buying Guide: Key Considerations for Exit Sign Battery Choices
- Battery type and capacity: SLA (sealed lead-acid) batteries are common for exit signs, offering reliability and low maintenance. Check the voltage (often 6V) and capacity (mAh) to match your sign model and expected run time.
- Run time during outages: Most battery-backed units provide a minimum emergency runtime (commonly 90 minutes). Verify the required duration for your facility and building code compliance.
- Replacement compatibility: If you are replacing a battery, ensure the exact battery model or compatible equivalents (voltage, connector type, and dimensions) to avoid fit issues.
- Wiring and installation: Corded signs with built-in batteries simplify installation but require a power source. Wireless or non-electrical options rely on ambient charging for photoluminescent models but do not provide battery backup.
- Mounting options: Consider top, side, or back mounting as well as canopy requirements for ceiling installations. Ensure the mounting hardware is included or compatible with your structure.
- UL and safety certifications: Look for UL-listed or UL-certified models to ensure compliance with local codes (e.g., NFPA 101, IBC) and safety standards for emergency lighting.
- Environment and durability: If the installation is in harsh or outdoor environments, check IP ratings, weather resistance, and temperature tolerances for battery performance and housing materials.
- Maintenance considerations: Some batteries are maintenance-free; others require periodic replacement. Factor in maintenance schedules and replacement costs.
- Photoluminescent versus battery-backed: Photoluminescent signs do not require power but depend on ambient light for charging. For guaranteed operation during outages, battery-backed options are essential.
