Profimaster Robot 2712 Replacement Battery 14.4V 2000mAh

Profimaster Robot 2712 — 14.4V Ni-MH Replacement Battery

This 14.4V, 2000mAh Ni-MH battery replaces the original cell in the Profimaster Robot 2712 robotic vacuum cleaner. It fits the 2712 platform directly and restores the voltage the drive and suction motors require to run a full cleaning cycle. Capacity is 2000mAh (28.8Wh), matching the factory specification.

• Robot 2712 platform fit: The 2712 uses a 14.4V Ni-MH pack with a specific cell count to maintain the voltage rail that both the drive wheels and suction motor draw from simultaneously. Swapping chemistry or voltage — even slightly — causes the BMS to reject the pack or the motors to run underspec.
• Bench tested on actual hardware: We cycled this cell through discharge under combined motor load — drive and suction active together — and confirmed the BMS did not trip on startup surge. Voltage held above 13V through the mid-discharge band where most worn cells collapse.
• Dock charging on the Robot 2712: Do not leave the 2712 sitting on its charging dock indefinitely between uses. Ni-MH cells in continuous trickle charge degrade faster than cells charged only when depleted. Charge to full, remove from the dock, and return it when the battery is low.

Suction dropping before the battery indicator reaches low on the Robot 2712

A partially blocked filter forces the suction motor to draw more current than its rated load. That extra draw pulls the pack voltage down faster than the indicator circuit expects, so suction weakens while the indicator still reads mid-charge. The fix is not the battery — clean or replace the filter first. If suction recovers after a filter clean, the cell is fine. If it still drops early with a clean filter, the pack voltage is sagging under load and the cell needs replacement.

Motor cuts out mid-cycle then restarts on its own

This is a BMS overcurrent trip, not a mechanical fault. When the suction path is restricted — blocked brush roll, clogged filter, or debris jam — the motor pulls above the BMS threshold and the pack shuts output to protect the cells. The unit recovers once current demand drops. Clear the blockage, then run a full discharge-to-charge cycle. If trips continue on a clean machine, check pack voltage immediately after a trip — anything below 12V under light load confirms cell degradation.
