If your Lithonia emergency light or exit sign fails its monthly test, has a beeping/charging fault, or won’t hold runtime during an outage, the battery is usually the first component to replace. This ELP L383 battery replacement is intended for Lithonia/Acuity emergency lighting battery-backup applications. Rebuild your existing pack.
Must send in old battery for rebuild. Once ordered we will send information on address to ship the old packs.

How to confirm compatibility (recommended)
- Find the battery label inside the fixture (or on the battery pack).
- Match: Voltage (V), Capacity (Ah or mAh), and Chemistry (NiCd, NiMH, Li-ion, SLA, etc.).
- Match the connector type and wire lead layout (2-wire, 3-wire, plug style, polarity).
- If you’re unsure, send us photos of the label + connector and we’ll help confirm fit before shipment.
Why replace the battery?
- Pass inspections: Weak batteries are a common reason emergency fixtures fail testing.
- Restore runtime: Fresh cells help maintain required emergency illumination duration.
- Cost-effective: Replace the battery instead of the entire fixture when the unit is otherwise working.
