ETA 2442 Verto 12V Ni-MH Replacement Battery 2000mAh

ETA 2442 Verto Series — 12V Ni-MH Replacement Battery (200AAHx10)

This is a 12V 2000mAh Ni-MH replacement battery for the ETA 2442 Verto cordless vacuum cleaner, including the 2442 90000, 2442 90001, and 2442 90002 variants. It replaces the original cell pack when the vacuum no longer holds a charge or suction drops off within minutes of starting. Capacity matches the factory specification at 2000mAh (24Wh).

• 2442 Verto platform fitment: The 2442 90000, 90001, and 90002 all share the same 12V cell pack format and connector orientation. The BMS on these units communicates with the charger through the same contact arrangement, so a correctly rated replacement cell restores normal charge acceptance without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on a 2442-series unit. The BMS accepted charge normally, held voltage through the full draw cycle, and the thermal cutoff did not trip under standard operating load.
• Dock charging behaviour on Ni-MH cells: Do not leave the vacuum sitting on the charging dock continuously. Ni-MH chemistry degrades noticeably faster under trickle charge than lithium cells do. Charge the pack fully, then remove the vacuum from the dock until the next use.

Cordless vacuum losing suction before battery indicator reaches low

On the 2442 Verto, suction can drop well before the battery indicator signals low charge. The most common cause is a partially blocked filter forcing the motor to draw above its rated current. The BMS reads this elevated draw as a high-load condition and reduces output voltage to protect the pack. Clean or replace the filter first — if suction recovers and the battery indicator is still showing mid-charge, the cell is fine and the issue was restriction, not capacity.

Motor cuts out briefly then restarts during vacuuming

This is a BMS overcurrent trip, not a dead battery. When the motor encounters sustained restriction — a blocked nozzle, a clogged filter, or heavy carpet fibres — current draw spikes past the BMS threshold and the pack cuts output to protect the cells. The BMS resets after a few seconds once current normalises, which is why the motor restarts on its own. Clear the blockage, confirm filter airflow is unrestricted, and the cutout should stop. If it continues with a clear filter, check cell voltage at rest — it should read at least 12.5V on a fully charged pack.
