Amtidy A325 Mini 14.4V Ni-MH Replacement Battery 2000mAh

Amtidy A325 Mini — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Amtidy A325 Mini cordless handheld vacuum. It restores suction power when the original cell has degraded or failed. Rated at 28.8Wh, it matches the voltage and chemistry of the factory-fitted pack.

• A325 Mini fit: The A325 Mini runs a 14.4V Ni-MH chemistry pack with a specific connector orientation and BMS communication — this replacement matches that configuration. Swapping to a different voltage or chemistry will cause the charger to reject the pack or the motor controller to misread charge state.
• Bench tested on actual hardware: We cycled this cell through multiple charge and discharge passes on a 14.4V Ni-MH charger. The BMS held cutoff correctly at both ends — no thermal flag, no mid-cycle drop-out under normal suction load.
• Dock charging behaviour on the A325 Mini: Do not leave the A325 Mini sitting on the charging dock continuously. Ni-MH cells take damage from sustained trickle charge — charge to full, then remove from the dock. Repeated overnight dock charging is one of the fastest ways to shorten this pack's cycle life.

Suction dropping before the battery indicator reaches low

This happens on the A325 Mini when a partially blocked filter forces the motor to draw more current than rated. The increased load causes voltage to sag across the Ni-MH cell before the charge indicator catches up. The vacuum feels underpowered, but the battery is not necessarily the cause. Clean or replace the filter first — if suction recovers, the cell is fine.

Motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a flat battery. When suction is restricted — blocked nozzle, clogged filter, or sustained carpet load — current draw spikes and the BMS cuts the circuit to protect the cell. The motor recovers after a short pause because the BMS resets once current demand drops. Clear the blockage or filter restriction before resuming; if the trip keeps repeating on an unblocked vacuum, the cell may no longer hold enough charge to sustain motor-start current without tripping.
