About this replacement
Van Lien 11190013V — 3.6V Ni-CD Replacement Battery (11190013V)
This is a 3.6V, 4000mAh Ni-CD cell for Van Lien emergency lighting units. It fits models 11190013V, 3SAVTD113LF, and SET A 3 ST D 4.0/HT LB. When the original cell can no longer hold charge, this replacement restores the fitting's ability to sustain illumination during a mains failure event.
- Fits 11190013V, 3SAVTD113LF, and SET A 3 ST D 4.0/HT LB: These fittings share the same 3.6V charge rail, cell footprint, and trickle-charge acceptance window — which is why one cell covers all three variants without modification.
- Bench tested on actual hardware: We ran this cell through a full charge cycle and a simulated mains-fail discharge. The BMS accepted the cell within its float voltage window and the fitting's charge indicator moved to green without manual intervention.
- First test cycle after installation: Within 24 hours of fitting the new cell, hold the test button for the full rated duration. This lets the charge controller register the new cell's capacity and confirm load acceptance before your next compliance inspection — skipping this step is the most common reason a new battery fails its first duration test.
Charge indicator staying red after new battery installation
Ni-CD cells shipped in storage state typically sit at 3.0–3.2V — below the float acceptance threshold many Van Lien charge controllers expect on first contact. The controller reads that voltage as a fault condition rather than a dischargeable cell, so the indicator stays red. Leaving the fitting connected to mains for 12–24 hours allows the trickle circuit to bring the cell up past the acceptance threshold, usually around 3.6V nominal. If the indicator has not moved to green after 24 hours, disconnect and reconnect mains power to trigger a fresh controller poll.
Emergency light dims partway through a duration test after replacement
A freshly installed Ni-CD cell has not yet gone through a full charge-discharge conditioning cycle, so its usable capacity at the start is below the rated 4000mAh. Under sustained load during a duration test, voltage sags earlier than it will after conditioning. This is not a faulty cell — it is a cell that has not yet reached rated capacity. Run one complete manual test cycle immediately after installation: hold the test button until the light cuts out, then allow a full 24-hour recharge before the compliance test. Capacity reaches its rated level within the first two full cycles.
