Buying Guide: What To Consider When Choosing Exit Sign Batteries
- Voltage and capacity: Ensure the battery’s voltage matches the exit sign’s requirements. Common options include 4.8V Ni-Cd and 6V 4.5Ah SLA. Higher capacity provides longer back-up time but may require a larger footprint.
- Chemistry type: Ni-Cd batteries offer robust performance and resilience in heat, but SLA (lead-acid) batteries typically provide higher capacity at a lower cost. Consider temperature exposure and maintenance needs.
- Compatibility: Check model numbers and compatibility lists. Using a battery labeled for your exact fixture family reduces the risk of fitment or performance issues.
- Pack size: Single replacements are convenient for one light, while packs (2 or 10) are cost-effective for multiple signs or future replacements.
- Life cycle and warranty: Look for batteries with longer expected life cycles and favorable warranty terms to minimize replacement frequency and total cost of ownership.
- Installation considerations: Some batteries ship with wire leads or mounting hardware; others are sold as the battery only. Plan for any needed adapters, harnesses, or tools.
- Safety and certifications: UL and other certifications indicate compliance with safety standards for electrical back-up systems, a key factor for commercial venues.
- Environmental and disposal: Nickel-cadmium batteries require proper disposal and recycling. Plan accordingly for compliance with local waste regulations.
- Operational reliability: In critical spaces (eg, hallways, exits, and egress routes), choose batteries with proven performance under typical power fluctuations and temperature conditions.
These considerations help balance immediate replacement needs with long-term reliability, ensuring exit signs remain operational during emergencies without unnecessary maintenance or downtime.
