ELB1P201N1 Battery Replacement for Emergency Lighting & Exit Signs
If your Lithonia emergency light or Lithonia exit sign won’t stay illuminated during a power outage, the backup battery pack is often the cause. This ELB1P201N1 battery replacement is intended for use in compatible emergency lighting and exit sign fixtures that require an ELB1P201N1-style battery pack.
Confirm the Correct Pack Before Ordering (Important)
Emergency lighting battery packs can look similar but differ in voltage, capacity, chemistry, wire leads, and connector type. To ensure the correct replacement, match these details from your existing pack label:
- Voltage (V) 1.2V
- Capacity (mAh) 1000 Mah
- Chemistry Ni-Cd
- Cell configuration AA
- Connector style & wire lead length
- Overall pack size (so it fits inside the housing)
- Replaces Custom-128, OSA045, BCN1P201N1, ANIC0027, ELB0300, 18008, BGN0300, ELB1P201N1
Fast match-up: Email or text a clear photo of your battery label and connector so we can verify compatibility before you order.

- Compatible emergency light and exit sign fixtures that specify ELB1P201N1 on the original battery label
FAQ
Q: Will this ELB1P201N1 battery fit my exit sign or emergency light?
A: Only if your existing battery label shows ELB1P201N1 (or the exact same voltage/capacity/chemistry) and the connector matches. Send a photo of your current pack and connector to confirm.
Q: My fixture has the same part number but the connector looks different—what do I do?
A: Connector type matters. Provide a clear connector photo (and wire count) so the correct pack/connector can be matched.
Q: How do I know if I need Ni-Cd or NiMH?
A: Match the chemistry printed on the original battery label. Using the wrong chemistry can cause poor performance or charging issues.
Q: My emergency light turns on, but doesn’t stay on long during a test. Is that the battery?
A: Often yes—reduced runtime is a common sign the battery pack is worn. Also check charger board condition and fixture age.
Q: Can I upgrade to a higher mAh?
A: Sometimes, if the charger circuit supports it and the pack still fits physically. Confirm before upgrading.
Information Gain
- ELB-style battery part numbers like ELB1P201N1 may be used across multiple fixture brands, but the correct replacement depends on matching the exact voltage, mAh capacity, chemistry, and connector—not just the part number.
- 1.2V 1000 Mah Nicad Wirelead.
- Emergency light batteries commonly fail by losing runtime before completely dying; fixtures that light briefly but fail a 90-minute test usually indicate a worn battery pack.
- Using the wrong chemistry (Ni-Cd vs NiMH) can lead to under-charging, overheating, or premature failure of both the battery and the charger board.
- Connector pin count and keying vary by manufacturer; visually confirming the connector prevents costly returns and downtime.
- Planned battery replacement every 3–5 years helps facilities maintain emergency lighting compliance and avoid failed inspections.
