Streamer YH08-W1690 Compatible Battery 9.6V 5000mAh Ni-MH

Streamer YH08-W1690 16W — 9.6V Ni-MH Replacement Battery (KRH33/62)

This is a 9.6V, 5000mAh Ni-MH replacement battery for the Streamer YH08-W1690 16W emergency lighting unit. It slots directly into the fitting and restores the backup illumination function lost when the original cell degrades. Confirm your fitting's part label reads KRH33/62 before ordering.

• YH08-W1690 16W platform fit: This cell matches the voltage rail, physical dimensions, and connector orientation the YH08-W1690 charge controller expects. A mismatched voltage forces the controller into a continuous trickle state, which damages the new cell within weeks.
• Bench tested on actual hardware: We ran this cell through a simulated mains-failure cycle. The charge controller accepted the new cell, transitioned from charge to float, and the lamp activated cleanly at the correct voltage threshold under full 16W draw.
• First test-cycle conditioning: Within 24 hours of installation, hold the test button for the full rated duration. This lets the cell accept a load cycle and gives the charge controller a baseline reading before any compliance test is logged against the fitting.

Charge indicator staying red after new battery installation

Ni-MH cells lose charge during storage. If the cell voltage drops far enough, the YH08-W1690 charge controller may not recognise it as a valid cell and holds the red fault indicator rather than entering normal charge mode. Leave the fitting connected to mains for a full 24-hour charge cycle before drawing any conclusions. If the indicator is still red after 24 hours, check the connector seating — a partially seated connector causes the same symptom. A fully charged and accepted cell should read approximately 11.0V across the terminals before the controller switches to float.

Emergency light dims partway through a duration test after replacement

A new cell that has not completed a full conditioning cycle will show an apparent capacity shortfall — the lamp dims or cuts before the rated duration ends. This happens because the charge controller has not yet established the cell's full charge ceiling. Run one complete manual test cycle, then allow a full 24-hour recharge before the next test. After that cycle, the cell should sustain the 16W lamp load across the full rated duration without dimming.
