Hoover Rogue 970 Robot Vacuum Replacement Battery 14.4V 2600mAh

Hoover Rogue 970 Robot Vacuum — 14.4V Li-ion Replacement Battery (440011973)

This 14.4V 2600mAh Li-ion battery replaces the OEM pack in the Hoover Rogue 970 Robot Vacuum, including the BH70970 and all Rogue 970 Wi-Fi Connected variants. The cell chemistry and BMS profile match the original, so the robot pairs with its dock and resumes scheduled cleaning without reconfiguration. Capacity is 2600mAh (37.44Wh) — identical to the factory specification.

• Rogue 970 platform fitment: The BH70970 and Rogue 970 Wi-Fi Connected models all run the same 14.4V battery rail with the same connector and BMS handshake. One cell revision fits every unit in this line — no adapter or firmware change needed.
• Bench tested on actual hardware: We cycled this cell through the Rogue 970 charge and discharge sequence. The BMS negotiated correctly with the dock charger, cutoff fired cleanly at low-voltage threshold, and charge acceptance held steady across repeated cycles.
• Dock charging habit for the Rogue 970: Do not leave the robot sitting on the dock between every run indefinitely. The Rogue 970 returns to dock after each job — pull it off once fully charged if it is not running on a schedule. Continuous trickle current accelerates capacity fade on this cell faster than periodic charge cycles do.

Suction dropping before the battery indicator reaches low

The Rogue 970 motor draws significantly more current when the filter is partially blocked — the battery voltage sags under that elevated load before the state-of-charge indicator reflects it. The BMS reads the voltage dip as a low-battery condition and throttles power to the motor, which the user sees as suction loss. The battery indicator can still show two bars when this happens. Clean the filter first, then check whether suction recovers — if it does, the battery is fine and the filter was the draw.

Motor cuts out mid-run then restarts after a pause

This is an overcurrent trip, not a dead battery. When the Rogue 970 hits dense carpet or a partial blockage, sustained restricted suction spikes current draw past the BMS overcurrent threshold. The BMS shuts the motor to protect the cell, the robot pauses, and once current drops the BMS resets and the motor restarts. The fix is to clear the blockage, empty the dustbin, and inspect the brush roll for hair wrap. If the trip still fires on open hard floor with a clean filter, measure resting voltage — a cell below 12.8V under no load needs replacement.
