ETA 3449 Moneto Replacement Battery 14.4V 2000mAh

ETA 3449 Moneto — 14.4V Li-ion Replacement Battery (344700082)

This is a 14.4V, 2000mAh Li-ion replacement battery for the ETA 3449 Moneto cordless vacuum cleaner. It slots into the Moneto's battery housing and restores suction power when the original cell degrades. OEM part numbers 344700082 and 344900120 both confirm fitment on this model.

• ETA 3449 Moneto fitment: The Moneto runs a 14.4V motor rail with a BMS handshake that checks cell voltage before enabling the motor driver. This replacement matches that voltage requirement and carries the same connector footprint as the factory pack — no adapter or modification needed.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the bench. The BMS held overcurrent protection correctly under simulated motor-start loads, and the protection board cut off cleanly at low-cell thresholds without latching the pack into a fault state.
• Dock charging on the Moneto: Do not leave the Moneto sitting on the charging dock continuously. Cordless vacuums on permanent dock charge develop capacity fade significantly faster than units charged only when depleted. Charge to full, then remove the vacuum from the dock.

Suction dropping before the battery indicator reaches low

The Moneto's motor draws sharply more current when the filter is partially blocked — airflow restriction forces the motor to work harder against backpressure. That elevated draw causes voltage to sag under load even when the cell is not genuinely depleted. The BMS reads the voltage drop as a low-cell condition and throttles power before the indicator LED signals low. Clean the filter first, then retest — a clear filter brings motor draw back within the normal current envelope.

Motor cuts out mid-use and then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to draw above the pack's rated discharge current, the protection board opens the output circuit to prevent cell damage. The pack resets after the thermal and current conditions normalise — typically within 30 to 60 seconds. Check the filter and the nozzle for blockages before resuming use. If the cutout repeats on a clear filter, verify the motor isn't drawing above the 14.4V pack's rated discharge threshold.
