ESYLUX SLC 7.2V Emergency Light Replacement Battery 10030956

ESYLUX SLC / SLD / SC/C Series — 7.2V Ni-MH Replacement Battery (10030956)

This is a 7.2V 700mAh Ni-MH replacement battery for ESYLUX emergency lighting units across the SLC, SLD, and SC/C series. OEM part number 10030956 matches the original cell configuration, voltage rail, and connector used in these fittings. It restores backup illumination capability when the original cell can no longer hold sufficient charge to meet duration test requirements.

• SLC, SLD, and SC/C compatibility: All three models share the same 7.2V battery bay, connector pinout, and charge controller logic. One cell format covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through a full discharge and recharge sequence on a matched ESYLUX fitting. The charge controller accepted the cell without fault codes, and the BMS reached float voltage cleanly within the expected window.
• First test cycle after installation: Within 24 hours of fitting, press and hold the test button for the full rated duration. This forces the charge controller to register the new cell's capacity baseline before the next scheduled compliance test. Skipping this step can cause the fitting to underreport available capacity.

Charge indicator staying red after new battery installation

A replacement Ni-MH cell that has been in storage typically arrives with a resting voltage below the charge controller's float acceptance threshold. The ESYLUX charge circuit interprets this as a fault condition rather than a new cell needing conditioning. Leave the fitting on mains power for a full 24-hour charge cycle without interruption. Once the cell climbs above approximately 7.0V resting voltage, the controller should step out of fault mode and the indicator will shift to green.

Emergency light dims noticeably partway through a duration test

This happens when the first test cycle runs before the cell has completed its initial conditioning charge. A partially charged Ni-MH cell delivers full voltage under light load but sags quickly when the lamp draws sustained current. The cell itself is not faulty — it needs one complete charge cycle at mains before it can deliver rated capacity under load. Allow a full 24-hour charge after installation, then re-run the duration test from the beginning.
