AGAiT e-clean EC01 14.4V Ni-MH Replacement Battery 2800mAh

AGAiT e-clean EC01 — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2800mAh Ni-MH replacement battery for the AGAiT e-clean EC01 cordless handheld vacuum. It fits the EC01's motor and charging circuit directly. When the original cell degrades and the vacuum loses suction well before the indicator drops, this is the part to replace.

• EC01 motor rail compatibility: The EC01 runs its brushed motor from a 14.4V Ni-MH pack with a specific current draw profile. Swapping chemistry or voltage breaks the charging handshake and trips the onboard protection circuit. This cell matches the original voltage rail and connector footprint so the charger recognises the pack without fault codes.
• Bench tested on actual hardware: We cycled this cell through multiple charge and discharge runs on the EC01 platform. The BMS handled inrush current on motor start without tripping, and the cell reached rated capacity by the third full cycle.
• Dock charging habit on the EC01: Do not leave the EC01 sitting on the charge dock between uses. Ni-MH cells on continuous trickle charge develop capacity fade faster than cells charged only when depleted. Charge to full, then remove the vacuum from the dock.

Suction dropping before the battery indicator reaches low

Ni-MH cells show voltage sag under load before the resting voltage falls far enough to trigger the low-battery indicator. On the EC01, a partially blocked filter forces the motor to draw more current than rated, which accelerates that sag. The result is noticeably weaker suction while the indicator still reads mid-charge. Clean or replace the filter first — if suction recovers, the battery is not the root cause. If the vacuum still sags with a clean filter, the cell has lost usable capacity and needs replacing.

EC01 motor cuts out mid-clean and then recovers after a pause

This is a BMS overcurrent trip, not a dead battery. When the EC01 picks up a blockage or runs with a clogged filter, motor current spikes above the protection threshold and the BMS shuts the output rail. The vacuum goes silent, and after 30–60 seconds the BMS resets and power returns. Clear the suction path, check the filter, and confirm the inlet and brush roll are free of debris. If cut-outs continue with an unobstructed vacuum, measure pack voltage at rest — it should read above 15.0V on a full Ni-MH cell in good condition.
