Bosch 14.4V Constructa Balay Neff Replacement Battery GPRHC18SV007

Bosch Constructa Balay Neff 751992 / Move 2in1 — 14.4V Ni-MH Replacement Battery (GPRHC18SV007)

This is a 14.4V 2200mAh Ni-MH replacement battery for Constructa, Balay, and Neff cordless stick and handheld vacuums, including the 751992 and Move 2in1 series. It replaces OEM part numbers GPRHC18SV007 and GP180SCHSV12Y2H. If your vacuum has lost suction power or the battery no longer holds a charge, this cell restores full motor voltage to the unit.

• 751992 / Move 2in1 platform fit: These models share a common 14.4V battery bay, connector housing, and BMS communication protocol across the Constructa, Balay, and Neff variants — the same cell services all of them without modification.
• Bench tested on actual hardware: We cycled this cell through load discharge on a 14.4V motor draw and confirmed the BMS holds steady voltage through the full discharge curve without early cutoff or thermal shutdown.
• Dock charging behaviour on the Move 2in1: Do not leave the vacuum sitting on the charging dock continuously. The Move 2in1 dock does not drop to a true maintenance charge — prolonged dock time pushes trickle current through Ni-MH cells and accelerates capacity fade. Charge to full, then remove the unit from the dock.

Suction dropping before the battery indicator reaches low

Ni-MH cells in cordless vacuums lose voltage under motor load faster than the indicator circuit tracks. The LED or bar display reads cell resting voltage, not loaded voltage — so the motor can be starved of its 14.4V rail while the indicator still shows two-thirds charge. A partially blocked filter makes this worse: restricted airflow forces the motor to draw more current, which pulls cell voltage down faster under load. Clean the filter first, then test suction — if it stabilises, the filter was the cause, not the battery.

Motor cuts out mid-clean and then recovers after a few seconds

This is a BMS overcurrent trip, not a battery failure. When the suction path is restricted — blocked filter, full dust cup, or a lodged obstruction — the motor draws above its rated current to maintain airflow. The BMS reads that spike and cuts the output circuit to protect the cell. After a few seconds, the BMS resets and power returns. Clear the obstruction or empty the dust cup and the cutout stops. If it persists with a clean filter and empty cup, measure cell voltage under load — it should hold above 12V; anything below that points to a degraded cell.
