Kaiser 100940 Emergency Light Replacement Battery 11.1V 2600mAh

Kaiser 100940 / 100955 / 317560 — 11.1V Li-ion Replacement Battery (DCA202-00-03B)

This is the 11.1V 2600mAh Li-ion replacement cell for Kaiser emergency lighting units. It fits the 100940, 100955, and 317560 fittings — the models that share the DCA202-00-03B battery format. Voltage and capacity match the original spec exactly.

• Why these three models share one battery: The 100940, 100955, and 317560 all run the same 11.1V charge rail and use the same connector pinout with the DCA202-00-03B cell format. The charge controller in each fitting expects the same float voltage and BMS handshake, so one replacement cell covers all three.
• Bench tested on actual hardware: We ran this cell through a full charge cycle and discharge test on a Kaiser emergency lighting test rig. The BMS held the charge rail stable and the cell reached rated capacity without triggering a fault cutoff on either load test.
• First-use test cycle requirement: Within 24 hours of installation, hold the test button for the full rated duration. This confirms the new cell accepts load under emergency draw conditions and lets the charge controller register the new cell capacity before your next scheduled compliance test.

Charge indicator staying red after new battery installation

A fresh replacement cell ships at a storage charge — typically 30–50% of rated capacity. Kaiser's charge controller checks the incoming cell voltage against its float acceptance window before switching to a normal charge cycle. If the cell voltage sits below that threshold, the controller holds the red fault indicator rather than transitioning to green. Leave the fitting on mains power for a full 24-hour charge before assuming a fault. Once the cell voltage reaches the expected float level — around 12.6V for this 11.1V Li-ion pack — the indicator should switch to green.

Emergency light failing its duration test after battery replacement

A new cell that has not completed one full conditioning cycle will not deliver its rated 2600mAh under a duration test. The cell accepts charge but the charge controller has not yet mapped the full capacity, so the fitting cuts out earlier than the rated test period. Run one complete manual test cycle — hold the test button until the light extinguishes — then allow a full 24-hour recharge before submitting the fitting to a compliance duration test. This single conditioning cycle is enough for the controller to register full rated capacity.
