ETA 2219 Nico Cordless Vacuum Replacement Battery 14.4V 2600mAh

ETA 2219 Nico — 14.4V Li-ion Replacement Battery

This is a 14.4V, 2600mAh Li-ion replacement battery for the ETA 2219 Nico cordless vacuum cleaner. It slots into the Nico's battery housing and restores power to the motor and suction system when the original cell has degraded. Capacity figure comes from the product data — 37.44Wh total energy.

• ETA 2219 Nico fit: The Nico runs a 14.4V motor rail with a BMS that checks voltage and current signature on startup. This cell matches that voltage rail and passes the handshake the vacuum's control board expects before it allows the motor to spin.
• Bench tested on actual hardware: We cycled this cell through full charge and load discharge on a vacuum motor test rig. The BMS handled the startup current surge without tripping, and voltage held steady under sustained suction load rather than sagging early.
• Dock charging habit on the Nico: The Nico's charging dock does not cut off trickle current once the cell hits full charge. Leave it docked between every use and the cell will absorb low-level charge continuously — this accelerates capacity fade faster than normal cycle wear. Charge to full, then remove it from the dock.

Suction dropping before the battery indicator reaches low on the Nico

The Nico's motor draws more current when airflow is restricted — a partially blocked filter or a tangled brush roll forces the motor to work harder to maintain suction pressure. That increased current draw pulls the cell voltage down faster than the indicator circuit expects, so the vacuum feels weak while the indicator still shows charge remaining. The BMS reads this as normal operation and does not trigger a warning. Clean the filter and clear the brush roll first — if suction recovers, the battery is not the problem.

Motor cutting out mid-clean and then recovering after a few seconds

This is a BMS overcurrent trip, not a dead cell. When the brush roll catches a blockage or the filter is heavily loaded, current spikes above the BMS protection threshold and the circuit opens to protect the cell. The BMS resets automatically after a short pause, which is why the motor comes back without any intervention. Clear the blockage, check the filter, and retry — if the cutout stops, the cell is functioning correctly. If it persists on a clean, unblocked vacuum, check that the cell voltage at rest is at or above 14.0V.
