Cecotec Conga 05429 Compatible Battery 14.4V 2500mAh

CECOTEC Conga 2090 Vision / 05429 — 14.4V Li-ion Replacement Battery

This is a 14.4V, 2500mAh (36Wh) Li-ion replacement battery for the CECOTEC Conga 2090 Vision and 05429 cordless stick vacuum. It fits the original battery slot and works with the same charging circuit. Use it when the original cell has lost capacity or stopped holding charge.

• Conga 2090 Vision and 05429 compatibility: Both models run the same 14.4V battery platform with a shared connector and BMS communication line. The replacement cell matches that voltage rail, so the vacuum's power management reads it correctly from first charge.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Conga platform. The BMS accepted the handshake, charge termination triggered at the correct voltage, and the motor draw stayed within the cell's rated current envelope under normal suction load.
• Dock charging habit for Conga vacuums: Do not leave the Conga on the charging dock permanently after the charge completes. Continuous trickle charging accelerates capacity fade on Li-ion cells in this voltage range. Charge to full, then remove it from the dock.

Suction dropping before the battery indicator reaches low on the Conga 2090 Vision

This happens when the motor draws more current than the cell can deliver at its present state of charge. A partially clogged filter forces the motor to work harder, pulling the cell voltage down early. The BMS reads that voltage sag as low charge and begins throttling power before the indicator catches up. Clean the filter first — if suction stabilises after that, the battery is not the cause.

Motor cuts out mid-clean then restarts after a few seconds

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — by a blocked filter, full dust container, or a carpet pile blockage — the motor pulls a sustained spike above the cell's safe current limit. The BMS disconnects the output to protect the cell, then resets once current drops. Clear the blockage, empty the container, and check the filter before assuming the battery is faulty.
