Cleanmaxx Smart Plus Replacement Battery BAT-101 14.4V 2600mAh

Cleanmaxx Smart Plus — 14.4V Li-ion Replacement Battery (BAT-101)

This is a 14.4V 2600mAh Li-ion replacement battery for the Cleanmaxx Smart Plus cordless vacuum cleaner. It fits directly in place of the original BAT-101 pack. When the original cell degrades and suction weakens noticeably mid-clean, this is the part to replace.

• Smart Plus motor compatibility: The Smart Plus draws current through a 14.4V rail with a BMS that monitors cell voltage under motor load. This replacement matches that voltage rail and connector spec, so the BMS handshake completes and the motor spins up without fault codes.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on the Smart Plus platform. The BMS held cutoff correctly at low voltage and allowed full charge acceptance without triggering overcharge protection prematurely.
• Dock charging on the Smart Plus: Remove the vacuum from the charging dock once the battery reaches full charge. The Smart Plus dock does not interrupt trickle current automatically — leaving it docked continuously accelerates capacity fade in the cell over weeks.

Suction dropping well before the battery indicator shows low

This happens when the motor is working harder than rated — usually a partially blocked filter causing restricted airflow. Increased motor draw pulls more current from the cell, which drops the pack voltage faster than the indicator can track. The indicator reads state-of-charge from open-circuit voltage, not from load-adjusted voltage, so it lags behind real depletion. Clean or replace the filter first before assuming the battery is at fault.

Motor cuts out briefly then recovers during a cleaning run

This is a BMS overcurrent trip. It triggers when the motor draws a current spike above the pack's continuous discharge threshold — most often caused by a blockage in the brush head or a clogged filter forcing the motor to labour. The BMS cuts power to protect the cell, then resets after a few seconds once current demand drops. Clear the blockage, check the filter, and confirm the cell voltage is above 12.0V before the next run.
