Buying Guide: Key Purchase Considerations
- Compatibility: Verify model numbers and voltage (4.8V Ni-Cd or 9.6V Ni-Cd) before purchase. Mis-match can lead to improper charging or failure during outages.
- Battery Chemistry: Ni-Cd offers reliable performance in older exit-sign systems and simple charging circuits, while newer packs may use Ni-Md or other chemistries. Check device specs.
- Backup Time: Most signs target 90 minutes of emergency operation. If longer backup is required, look for higher-capacity cells and compatible signs.
- Installation: Consider whether the unit is a direct replacement or part of a larger sign kit. Some products include mounting hardware, while others are simple battery swaps.
- Durability: Look for signs with fire-retardant housings and damp-location ratings for commercial environments. Ensure IP ratings align with installation site conditions.
- Maintenance: Some products accompany a test switch and indicators to simplify routine checks. Factor in maintenance requirements for ongoing safety compliance.
- Certifications: UL-listed or equivalent certifications help ensure compliance with safety standards for exit and emergency lighting.
- Budget vs. Longevity: While initial cost is important, prioritize units with proven longevity and readily available replacement packs to reduce long-term maintenance costs.
In summary, the best battery choices balance compatibility with the exit-sign model, reliable backup duration, and straightforward installation. For facilities with mixed signage, selecting a mix of direct-replacement batteries and compatible backup-sign kits can simplify maintenance and ensure consistent safety signaling across spaces.
