Proscenic Pro806 Replacement Battery 14.4V 2800mAh

Proscenic Pro806 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2800mAh Ni-MH battery pack for the Proscenic Pro806 cordless stick vacuum. It replaces the original pack when suction power drops or the vacuum no longer holds a charge. Voltage and cell chemistry match the factory specification exactly.

• Pro806 platform fit: The Pro806 motor runs on a 14.4V rail. The connector and cell arrangement in this pack match that rail directly. No adapter or wiring modification is needed.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Pro806 platform. The BMS held within the expected voltage window across the full discharge curve, and the vacuum's motor drew current without triggering cutoff under normal suction load.
• Dock charging habit on the Pro806: Do not leave the Pro806 sitting on the charging dock continuously. Ni-MH cells on trickle charge develop capacity fade faster than cells charged only when depleted. Charge to full, then remove the vacuum from the dock.

Suction dropping before the battery indicator reaches low

Ni-MH cells show a flatter discharge curve than Li-ion, but they still sag under sustained high-draw loads. On the Pro806, a partially blocked filter forces the motor to pull more current than rated. That extra draw drags cell voltage down early, and suction weakens before the indicator flags a low battery. Clean or replace the filter first — if suction recovers and holds, the battery is not the problem. If the pack still sags under a clean filter, the cells have aged past useful capacity.

Motor cutting out mid-use then recovering after a short pause

This is a BMS overcurrent trip, not a dead battery. When suction airflow is restricted — blocked filter, clogged brush roll, or a sustained hard-floor-to-carpet transition — current spikes above the BMS threshold and the pack disconnects to protect the cells. The pack recovers once it cools slightly, which is why the vacuum restarts after a pause. Clear the blockage and check the filter before assuming the battery is faulty. If trips continue on a clean machine, measure pack voltage at rest — a healthy charged Ni-MH pack at 14.4V nominal should read above 16V immediately off charge.
