LumaPro 6CGL6 Emergency Light Replacement Battery 3.6V 800mAh

LumaPro 6CGL6 — 3.6V Ni-CD Replacement Battery (48H467)

This is a 3.6V, 800mAh nickel-cadmium cell for the LumaPro 6CGL6 emergency lighting unit (OEM part 48H467 / 48H467A). It fits directly into the fitting and connects to the onboard charge controller. Capacity is 800mAh (2.88Wh) — matched to the original cell specification.

• 6CGL6 fitting compatibility: The 6CGL6 uses a single Ni-CD cell on a fixed trickle-charge circuit. Voltage and cell geometry must match the original exactly — the charge controller does not negotiate with the cell, it just pushes a constant current. A mismatched capacity or chemistry will either undercharge or damage the cell over time.
• Bench tested on actual hardware: We ran this cell against the charge controller on the 6CGL6 fitting. The BMS accepted the cell without fault, float voltage stabilised at 3.6V, and the charge indicator transitioned to green within the expected window after a full conditioning cycle.
• First test cycle after installation: Within 24 hours of fitting, hold the test button for the full rated duration. This forces the cell through one complete load cycle and allows the charge controller to register actual cell capacity before your next scheduled compliance test. Skip this step and the first duration test result will likely be low.

Charge indicator staying red after new cell installation

A Ni-CD cell that has been in storage for months will present a resting voltage outside the float acceptance window of the 6CGL6 charge controller. The controller reads that voltage as a fault rather than a discharged cell, so the indicator stays red. Leave the fitting powered for 12–24 hours without interruption — the trickle charge will bring the cell voltage into the acceptance range and the indicator will clear. If it does not clear after 24 hours, check terminal contact and confirm cell polarity.

Emergency light fails its duration test after a confirmed good installation

A new cell needs at least one full charge-discharge cycle before it reaches rated capacity — this is a characteristic of Ni-CD chemistry, not a defect. If the fitting goes straight into a compliance test before that first cycle completes, the cell will not deliver full capacity and the test will fail. Run the manual test cycle immediately after installation, let the fitting charge back to green, then submit to the compliance test. The cell should reach rated capacity after that first full cycle at 3.6V float.
