Candy Hoover RBC004B011 Robo 14.4V Replacement Battery 2000mAh

Candy Hoover RBC004B011 Robo — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Candy Hoover RBC004B011 Robo robotic vacuum and related models including the RBC007B011, RBC001011, and RBC002011. It powers the drive motors and navigation board that keep the robot moving and orienting during a cleaning cycle. Capacity is rated at 28.8Wh — matching the original specification.

• RBC series compatibility: These Candy Hoover robotic vacuums share the same 14.4V battery rail, connector footprint, and BMS communication protocol across the lineup, which is why one battery covers all listed models.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on the RBC platform. The BMS accepted the cell chemistry without fault codes, and both drive motor and suction motor drew current within expected limits throughout.
• Dock charging habit for this robot: Do not leave the RBC004B011 sitting on the dock continuously between uses. Ni-MH cells in robotic vacuums develop capacity fade faster under constant trickle charge than under charge-and-remove cycles. Charge to full, then lift the robot off the dock until the next scheduled clean.

Suction dropping before the battery indicator reaches low on the RBC004B011

The RBC004B011 runs two motors simultaneously — drive and suction. When the suction motor draws more current than rated, usually from a partially blocked filter or full dustbin, voltage across the battery pack sags earlier than the charge indicator accounts for. The indicator reads state of charge, not real-time voltage under load. Clean the filter and empty the bin before every cycle, and the suction motor stays within its rated draw, keeping pack voltage stable until genuine depletion.

Motor cuts out mid-cycle then recovers after a few seconds

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked inlet, clogged filter, or hair wrapped around the brush roll — the suction motor spikes current draw above the BMS threshold and the pack disconnects to protect the cells. The BMS resets after a short thermal delay, which is why the robot starts moving again on its own. Clear the restriction, then verify pack voltage reads at or above 14.4V on a multimeter before docking to charge.
