Pure Clean PUCRC95 Replacement Battery 14.4V 1800mAh

Pure Clean PUCRC95 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 1800mAh Ni-MH replacement battery for the Pure Clean PUCRC95 robotic vacuum cleaner. It restores power to the drive motor and navigation systems when the original cell degrades or stops holding a charge. Voltage and capacity match the original specification exactly.

• PUCRC95 platform fit: The PUCRC95 runs its motor, sensors, and wheel drive from a single 14.4V Ni-MH cell pack. This replacement matches that voltage rail and physical footprint — 101.66 x 43.78 x 29.85mm — so it seats correctly in the battery bay without modification.
• Bench tested on actual hardware: We cycled this cell through drive and suction loads on the bench. The BMS responded correctly to sustained motor draw and recovered cleanly after load spikes — no false cutoffs under normal cleaning cycles.
• Dock charging habit on Ni-MH cells: Do not leave the PUCRC95 on its charging dock continuously. Ni-MH chemistry suffers capacity fade faster than Li-ion under trickle charge. Charge the battery to full, then remove the unit from the dock until the next cleaning session.

Suction dropping before the battery indicator reaches low

This is a motor voltage sag issue, not always a dead battery. When the filter is partially blocked, the motor pulls harder to maintain airflow — drawing more current than the cell is rated for at that state of charge. The BMS throttles output before the indicator registers low, so the vacuum loses suction while the display still shows charge remaining. Clean or replace the filter first, then retest. If suction holds, the battery is fine.

Motor cutting out mid-cycle and then recovering on its own

This points to a BMS overcurrent trip caused by sustained restricted airflow — most often a clogged filter or a partial blockage in the intake path. The BMS cuts the motor to protect the cell, then resets once current demand drops. It is not a faulty battery. Clear any blockage, clean the filter, and confirm the intake path is unobstructed before running a full cycle. If the cutout continues with a clean filter, verify cell voltage sits above 12V at rest after a full charge.
