Legrand 111 914 Emergency Lighting Replacement Battery 1.2V 1500mAh

Legrand 111 914 / Sati Series — 1.2V Ni-MH Replacement Battery (062625)

This is a 1.2V 1500mAh Ni-MH cell for Legrand emergency lighting units. It fits the 111 914, Sati 111 013V, Sati Connecte 113 218V, adressable 112 013V, and more than 25 additional Legrand fittings. Voltage and capacity match the OEM spec exactly — 1.2V, 1500mAh (1.8Wh).

• Sati and addressable series compatibility: These fittings share the same 1.2V NiMH charge rail and AA-format cell housing. The charge controller targets the same float voltage across all variants, so one cell type covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence on a Legrand-compatible emergency lighting test rig. The BMS accepted the cell on first connection, and charge current stepped down correctly at full capacity without fault codes.
• First-cycle compliance prep: Within 24 hours of installation, hold the test button for the full rated duration. This confirms the cell accepts load under real conditions and lets the charge controller register the new capacity before your next scheduled compliance test.

Charge indicator staying red after new battery installation

A Legrand emergency fitting expects the incoming cell to sit within a narrow voltage window before it shifts from bulk charge to float. A new cell stored for several months can arrive below that acceptance threshold. When that happens, the controller holds the red fault state and does not progress the charge cycle. Leave the fitting on mains power for 24 hours — the controller will trickle-charge the cell until it crosses the acceptance threshold and the indicator moves to green. If it stays red past 48 hours, measure the cell with a multimeter; it should read above 1.0V open-circuit.

Emergency light dims and cuts short during a duration test

Dimming partway through a test usually means the cell has not yet reached full charge capacity — not that the cell is faulty. On the first activation after replacement, the charge controller has no history for the new cell and may undercharge it before the test runs. Run a full manual test, then return the fitting to mains power for a complete 24-hour charge before testing again. A fully conditioned cell should sustain rated output voltage above 1.0V through the entire test duration.
