E.Ziclean Furtiv 14.4V Ni-MH Replacement Battery 2000mAh

E.Ziclean Furtiv — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the E.Ziclean Furtiv robotic vacuum cleaner. It slots into the same bay as the original and connects to the same charging and motor circuit. Capacity is 2000mAh (28.8Wh), matching the original specification.

• Furtiv battery bay fit: The Furtiv uses a fixed 14.4V Ni-MH pack with a specific cell arrangement and connector orientation. This replacement matches those physical and electrical parameters — same cell count, same voltage rail, same connector position.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Furtiv platform. The BMS accepted charge from the original dock without fault, and the motor circuit drew current within normal operating range across flat and low-pile carpet surfaces.
• Dock charging discipline on the Furtiv: Do not leave the Furtiv sitting on its dock between uses permanently. Ni-MH cells on continuous trickle charge lose capacity faster than cells charged only when depleted. Charge to full, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low

Ni-MH cells show a gradual voltage drop under load rather than a sharp cutoff. When the Furtiv's motor draws sustained current across a full cleaning cycle, a degraded or partially discharged pack sags below the voltage needed to maintain full suction — even while the indicator still reads mid-charge. This is voltage sag under load, not a dead battery. A fresh pack at full charge holds the voltage rail steady and keeps suction consistent through the cycle.

Motor cutting out mid-cycle and then recovering after a few seconds

This is a BMS overcurrent trip, not a faulty battery. When the Furtiv's brush roll or intake is partially blocked, the motor draws more current than its rated load to maintain speed. The BMS reads this as an overcurrent event and cuts power to protect the pack. After a few seconds the BMS resets and the motor restarts. Clean the filter and check the brush roll for hair or debris wrapped around the axle, then run a full charge cycle and test — normal motor current should stay below the trip threshold.
