Schneider RILUX 2.4V Replacement Battery TD310232 1600mAh

Schneider RILUX / LUXA Series — 2.4V Ni-CD Replacement Battery (TD310232)

This is a 2.4V, 1600mAh nickel-cadmium replacement cell for Schneider emergency lighting units including the RILUX, RILUX 6, LUXA, and OVA37027. It slots directly into the fitting and feeds the charge controller that keeps the lamp circuit live during a mains failure. Capacity is 1600mAh (3.84Wh), matching the original cell spec.

• RILUX and LUXA platform compatibility: These fittings share a common charge controller voltage rail and cell format — same connector pitch, same 2.4V nominal, same NiCd chemistry handshake. Swapping to a different chemistry will misread cell state and trip the fault LED.
• Bench tested on actual hardware: We ran this cell through a full charge cycle on a RILUX-compatible charge controller. The BMS accepted the cell within the float window, held trickle charge correctly, and showed no overcharge flags across a 48-hour soak.
• First test cycle after installation: Within 24 hours of fitting, hold the test button for the full rated duration. NiCd cells fresh from storage have not yet reached rated capacity — this one full load cycle lets the charge controller register the actual cell capacity before any compliance test is logged.

Charge indicator staying red after fitting a new TD310232 cell

A red charge indicator after installation usually means the cell voltage is sitting outside the controller's float acceptance window. NiCd cells lose charge during storage, and a deeply discharged cell can read low enough that the charge controller flags a fault rather than entering trickle mode. Leave the fitting powered for 12 to 24 hours — most RILUX controllers will re-enter the charge cycle once cell voltage climbs above 2.1V. If the indicator stays red past 24 hours, measure cell voltage at the terminals: anything below 1.9V indicates a storage-depleted cell that needs a slow top-up before the controller will accept it.

Emergency light dims partway through a duration test after battery replacement

This is a capacity conditioning issue, not a faulty cell. A NiCd cell installed directly from packaging has not completed a full charge-discharge cycle and will not deliver its full rated 1600mAh on the first test. The lamp dims when cell voltage sags under load before the rated duration is reached. Run one complete manual test cycle — full load until cutoff, then a full recharge — before scheduling any compliance inspection. After one full cycle, the cell reaches rated capacity and the duration test should pass at the correct cell cutoff voltage of around 1.8V.
