Buying Guide: Key Purchase Considerations
- Voltage and compatibility: Confirm the sign’s operating voltage (2.4V, 3.6V, 4.8V, 9.6V, or 1.2V) and match it with a compatible Ni-Cd battery to avoid underpowered backups or fit issues.
- Capacity and runtime: Higher mAh generally extends backup runtime. Evaluate your outage duration needs and whether a spare capacity margin is needed for overlapping maintenance cycles.
- Battery chemistry: Nickel-Cadmium (Ni-Cd) offers robust performance across temperature ranges and rapid recharge capabilities, but consider long-term environmental disposal and potential memory effects; newer Ni-Md alternatives exist but may alter compatibility.
- Model compatibility: Review the list of supported models (EXIT sign brands and specific SKUs) to ensure the replacement battery fits the retrofit or new-install scenario.
- Safety and protections: Look for batteries with built-in protections against over-voltage, over-current, short-circuits, and proper charging circuitry to maintain safety in electrical spaces.
- Packaging and replacement frequency: Multi-pack options (e.g., 2-pack or 5-pack) simplify stocking and regular replacements, reducing downtime during maintenance windows.
- Warranty and supplier support: Favor products with clear warranty terms and responsive customer service, especially for critical life-safety equipment.
- Environmental and disposal considerations: Ni-Cd batteries require proper recycling; verify local regulations and supplier guidance for safe disposal.
