Hurricane Spin Scrubber 3.6V Ni-MH Replacement Battery 2000mAh

Hurricane Spin Scrubber — 3.6V Ni-MH Replacement Battery (8877731412181)

This 3.6V 2000mAh Ni-MH cell replaces the original battery in the Hurricane Spin Scrubber cordless cleaning tool. The Spin Scrubber uses a rotating brush head to clean tiles, grout, and bathroom surfaces. When the original cell loses capacity or stops holding a charge, this unit restores full function.

• Spin Scrubber platform fit: The Spin Scrubber runs a single 3.6V Ni-MH cell to drive its brush rotation motor. The connector pinout and cell dimensions — 129.90 x 24.30 x 22.50mm — match the original housing without modification.
• Bench tested on actual hardware: We ran this cell through full charge and load cycles on the Spin Scrubber platform. The BMS accepted charge without fault, and motor rotation held consistent speed through the discharge curve.
• Ni-MH charge cycling on cordless scrubbers: Ni-MH cells in light-draw tools degrade faster when charged in short, incomplete cycles. Let the Spin Scrubber run until the motor noticeably slows before placing it on charge — partial cycling accelerates capacity fade in Ni-MH chemistry.

Why the Spin Scrubber brush slows before the battery is fully flat

Ni-MH cells show a gradual voltage drop across discharge rather than a sharp cutoff. As the cell approaches depletion, the motor receives less voltage and brush rotation slows noticeably — even though the battery is not fully exhausted. This is normal Ni-MH behaviour, not a fault with the motor or the replacement cell. Running it until rotation nearly stops gives the most complete discharge cycle and extends cell life over time.

Replacement cell charges but scrubber stops spinning after a few seconds

This usually points to a shallow initial charge rather than a faulty cell. Ni-MH cells shipped in storage state often need one full charge cycle before the BMS reports accurate capacity. If the scrubber stops after a few seconds on first use, place it back on charge for the full charge duration — typically until the indicator shows complete — then retry. If the fault persists after two full cycles, check the connector contacts for oxidation and clean with isopropyl alcohol before assuming a cell fault.
