About this replacement
Kaufel 011110 / 001870 — 6V Ni-CD Replacement Battery (BGN800-5DWP-PRB830EC)
This is a 6V, 800mAh nickel-cadmium replacement cell for Kaufel emergency lighting units, specifically models 011110 and 001870. These fittings provide backup illumination for exit routes and evacuation signage during mains failure. Capacity is 4.8Wh, matching the original OEM specification.
- Kaufel 011110 and 001870 compatibility: Both models share the same 6V cell format, connector pinout, and charge controller float voltage. A single cell revision covers both fittings without any wiring modification.
- Bench tested on actual hardware: We cycled this cell through a full charge and load discharge on the 011110 fitting. The charge controller accepted the new cell without fault, and the BMS held steady across the full discharge curve without tripping.
- Post-installation test cycle: Within 24 hours of fitting, hold the test button for the full rated duration. This confirms the new cell accepts load and lets the charge controller register capacity before the next scheduled compliance inspection.
Emergency light failing its duration test after battery replacement
A freshly installed Ni-CD cell does not ship at full charge. Storage discharge means the cell may only hold a fraction of its 800mAh capacity on the day of installation. Running a duration test immediately after fitting will likely result in a short illumination period, which can trigger a failed compliance log. Allow the fitting to trickle charge for at least 24 hours before conducting any timed duration test. After one full charge cycle, the cell reaches rated capacity and the fitting will hold its required output for the full test period.
Charge indicator staying red after new battery installation
The charge controller in these Kaufel fittings monitors incoming cell voltage at float acceptance. A cell that has self-discharged below approximately 5.4V during storage sits outside that acceptance window, so the controller continues to flag a fault rather than switching to green. Leave the fitting powered on the mains for a full 24-hour conditioning period — the trickle charge will bring the cell voltage up into the acceptance band. If the indicator remains red after 24 hours, check the cell connector seating and confirm terminal voltage at the cell tabs reads at least 5.8V.
