Buying Guide
- Chemistry considerations: Ni-Cd batteries are compact and fast-recharging but have lower energy density and memory effects. SLA (lead-acid) batteries typically offer higher capacity and longer shelf-life for backup applications, with good performance across varying temperatures.
- Voltage and capacity: Ensure the battery voltage matches your sign’s requirements (commonly 4.8V or 6V) and choose capacity (mAh or Ah) based on desired run-time during outages and the number of signs supported.
- Pack size and economy: For small installations, 2-pack solutions minimize waste; for larger buildings, 10-pack options reduce restocking frequency and simplify procurement.
- Model compatibility: Check model numbers and compatibility lists to avoid mismatches with Emerlight, Lithonia, Hubbell, Dantona, and similar brands. Look for direct replacement claims when possible.
- Maintenance and safety: SLA batteries are maintenance-free but heavier; Ni-Cd batteries tolerate frequent cycling and can be more temperature tolerant in some environments. UL certifications and correct polarity connections are essential for safety compliance.
- Installation considerations: Verify fit within fixture enclosures, terminal types (F1 or equivalent), and whether mounting hardware or wiring harnesses are required or included.
- Environmental and disposal: Follow local guidelines for safe disposal of old batteries and choose manufacturers with recycling programs where available.
- Warranty and support: Prefer brands offering warranties or replacement policies on backup batteries to mitigate early failures and ensure long-term reliability.
