ETA 3449 Moneto Cordless Vacuum Replacement Battery 14.4V 3000mAh

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

This is a 14.4V, 3000mAh Li-ion replacement battery for the ETA 3449 Moneto cordless vacuum cleaner. It slots into the original battery housing and restores suction power when the factory cell has degraded or stopped holding charge. OEM part numbers 344700082 and 344900120 both apply to this platform.

• ETA 3449 Moneto platform fit: The 3449 Moneto uses a 14.4V rail with a BMS handshake tied to this specific cell format. Swapping to a mismatched voltage or connector causes the charger to reject the pack entirely — this replacement matches the original electrical spec to avoid that.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the 3449 Moneto platform and confirmed the BMS completed full charge cycles without tripping overcurrent cutoff under normal suction loads. Cell voltage held steady across repeated draw cycles.
• Dock charging habit on the Moneto: Do not leave the vacuum sitting on the charging dock permanently. The 3449 Moneto charges by trickle when the dock senses a full cell, and sustained trickle current degrades Li-ion capacity faster than anything else on this device. Charge to full, then remove it.

Suction dropping before the battery indicator hits low on the 3449 Moneto

This happens when the motor draws more current than the BMS expects — usually because airflow restriction forces the motor to work harder. The BMS reads the elevated draw as a low-voltage condition and throttles output before the indicator reflects actual state of charge. The fix is almost always the filter: a partially blocked filter on the Moneto raises motor current draw significantly. Clean or replace the filter first, then test suction under the same load.

Motor cutting out mid-use and recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the motor pulls current above the pack's rated threshold — usually from sustained restricted airflow or a blockage — the BMS disconnects the cell to protect it, then resets after the overcurrent condition clears. Check the filter and the intake path before assuming the battery is at fault. If the motor cuts out even on a clean filter with no blockage, verify the cell is fully charged to 14.4V before running the vacuum again.
