Veluce Vivo 14.4V Ni-MH Replacement Battery 4000mAh

Veluce Vivo — 14.4V Ni-MH Replacement Battery

This is a 14.4V 4000mAh Ni-MH replacement battery for the Veluce Vivo cordless vacuum cleaner. It slots in when the original cell has lost capacity or stopped holding charge, restoring cordless operation for everyday floor and carpet cleaning. Voltage and cell chemistry match the Vivo's motor control board exactly.

• Veluce Vivo platform fit: The Vivo runs a 14.4V Ni-MH architecture with a specific cell-pack geometry — 179 × 51 × 52 mm. This replacement matches that geometry and voltage rail so the motor draws current normally from first use.
• Bench tested on actual hardware: We cycled this pack through full charge and draw loads consistent with vacuum motor demand. The BMS held stable under sustained high-draw passes and cut off cleanly at the lower voltage threshold without false trips.
• Dock charging on the Vivo: Do not leave the Vivo sitting on its charging dock indefinitely. Continuous dock contact delivers a low-level trickle that accelerates Ni-MH capacity fade faster than periodic charge cycles do. Charge to full, then remove it from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

On the Vivo, suction can drop noticeably while the battery indicator still shows mid-range charge. The cause is usually voltage sag — the motor draws higher current under load, and an aged or partially discharged cell cannot maintain the voltage the motor needs to sustain full airflow. A partially blocked filter makes this worse because restricted airflow forces the motor to work harder, pulling more current than the pack can cleanly supply. Fitting a fresh 4000mAh cell addresses the voltage sag side; confirm the filter is clear before condemning the battery entirely.

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

This pattern — motor stops, brief pause, motor restarts — is a BMS overcurrent trip. The battery management system cuts power when current draw spikes above a threshold, then resets once the pack temperature or load drops. On the Vivo, the most common trigger is a restricted suction path: blocked filter or blocked brush roll forces the motor into a stall-adjacent state that spikes current draw. Clear the filter first. If the cut-outs continue on an unobstructed machine with a fresh cell, check that the pack is fully charged to 14.4V before each session.
