GE 60401005 Emergency Light Replacement Battery 6V 2000mAh

GE 60401005 / 60410C5 — 6V Ni-MH Replacement Battery

This is a 6V, 2000mAh Ni-MH replacement cell for the GE 60401005 and 60410C5 emergency lighting units. It slots into the fitting and powers the lamp during mains failure, keeping the exit route illuminated until power is restored. Voltage and capacity match the original GE specification exactly.

• GE 60401005 and 60410C5 compatibility: Both units run the same 6V charge rail and use an identical cell footprint — 52.38 x 43.46 x 27.20mm — so one cell covers both fittings without modification to the connector or housing.
• Bench tested on actual hardware: We ran the cell through a full mains-off simulation. The charge controller accepted the cell without fault, the BMS held steady voltage under lamp load, and the fitting returned to float charge once mains was restored.
• First-cycle test after installation: Within 24 hours of fitting, hold the test button for the full rated duration. This lets the charge controller register the new cell capacity and confirms the lamp holds load before your next scheduled compliance test.

Charge indicator staying red after fitting the new cell

A Ni-MH cell discharged during storage can arrive with a terminal voltage below the fitting's float acceptance window. The charge controller reads this as a fault rather than a normal charging state and holds the red LED. Leave the fitting connected to mains for a full 24-hour charge cycle without interruption. Once the cell voltage climbs into the acceptance window, the controller registers it correctly and the indicator shifts to green.

Emergency light dims or cuts out partway through a duration test

A new cell that has not yet completed one full charge cycle from a low storage voltage will show reduced capacity under sustained lamp load — the voltage sags before the rated duration is reached. This is not a faulty cell; it is an unconditioned one. Allow 24 hours on charge before running the test. After one complete charge and discharge cycle, the cell reaches its rated 2000mAh and sustains full lamp brightness for the duration.
