Dite International A320 Cordless Vacuum Replacement Battery 14.4V

Dite International A320 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Dite International A320 cordless vacuum cleaner. It fits the A320 handheld and stick vacuum models where the original cell has degraded after repeated charge cycles. Capacity figures are taken directly from product data — 28.8Wh total energy storage.

• A320 fit confirmation: The A320 runs a 14.4V Ni-MH pack with a specific connector orientation and cell count that matches this replacement. Swapping chemistry — for example, fitting a Li-ion pack — will mismatch the charger voltage curve and damage both the charger and the new cell.
• Bench tested on actual hardware: We ran this cell through the A320's charge and discharge cycle. The BMS responded correctly at both ends — no false low-voltage cutoff at start, and no overcharge trip during a full charge sequence.
• Dock charging on the A320: Do not leave the A320 sitting on the charging dock continuously. Ni-MH cells in cordless vacuums develop capacity fade faster under constant trickle charge than under normal charge-then-remove cycles. Charge fully, then pull the vacuum off the dock.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when motor current draw spikes under load — usually a partially blocked filter or brush roll — and the battery voltage sags below the motor's operating threshold before the indicator circuit registers a low charge state. The indicator reads resting voltage, not voltage under load. Clean the filter first. If suction recovers, the battery was fine — the restricted airflow was forcing the motor to pull more current than the pack could sustain cleanly.

A320 motor cuts out mid-use then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When suction is sustained against a blockage or clogged filter, motor current spikes and the BMS opens the circuit to protect the cell. The pack resets after the overcurrent condition clears — which is why the vacuum comes back after a pause. Check the filter and inlet for partial blockage before assuming the battery is faulty. A fully clear airflow path keeps motor draw within the BMS trip threshold, typically below the overcurrent cutoff at 14.4V nominal load.
