Buying Guide: Key Purchase Considerations
- Voltage and capacity alignment: Ensure the battery provides 4.8V nominal and a capacity that meets your fixture’s runtime requirements. Higher mAh typically means longer back-up power, but confirm the device’s tolerance for higher discharge rates.
- Chemistry and longevity: Ni-Cd chemistry supports rugged performance and long cycle life but has higher memory and environmental considerations than Ni-Mh. Verify replacement compatibility with your existing back-up system’s chemistry.
- Physical dimensions and connector type: Confirm the battery’s dimensions match the fixture’s housing and that the connector (e.g., SM-2P) is compatible with your wiring harness or leads.
- Compatibility with model families: Look for documented compatibility with common exit-light models (BL93NC487, BAA-48R, OSA126, Lithonia D-AA-series, etc.).
- Installation and serviceability: Prefer batteries with simple installation or included wiring harnesses. Avoid models requiring welding or specialized tools unless the fixture supports it.
- Bulk vs. single packs: For facilities with multiple fixtures, consider bulk options to reduce replacement time and ensure consistent performance across units.
- Environmental and safety considerations: Some Ni-Cd batteries contain cadmium; follow local disposal guidelines and recycling options. Ensure compliance with any facility safety policies.
