Cecotec Conga 5290 Ultra Replacement Battery 14.4V 2600mAh 93592

Cecotec Conga 5290 Ultra Home — 14.4V Li-ion Replacement Battery (93592)

This 14.4V 2600mAh Li-ion battery replaces the original cell in the Cecotec Conga 5290 Ultra Home and Conga 5290 Ultra robotic vacuum cleaners. It matches OEM part number 93592 and slots directly into the battery bay with no modification. Capacity is 37.44Wh — identical to the factory specification.

• Conga 5290 Ultra platform fit: Both the Ultra Home and Ultra share the same 14.4V power rail, connector pinout, and BMS communication protocol — one battery covers both variants without any firmware or hardware difference.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on a Conga 5290 Ultra dock. The BMS accepted the charger handshake without fault codes, and cell voltage held stable across the cleaning cycle with no cutoff events.
• Dock charging habit on robotic vacuums: Do not leave the Conga on its dock continuously between uses. Robotic vacuums kept on permanent trickle charge develop capacity fade faster than units charged only when the cell is depleted — charge to full, then remove from the dock until the next scheduled clean.

Suction dropping before the battery indicator reaches low

The Conga 5290 Ultra's motor draws significantly more current when the filter is restricted or the brush roll is partially blocked. That elevated draw causes cell voltage to sag under load — the BMS reads a low-voltage condition and reduces motor power before the indicator LED has stepped down. The robot appears to lose suction mid-run, but the battery is not the root cause. Clear the filter and brush roll first, then retest — if suction restores and holds, the cell is functioning correctly.

Motor cutting out and recovering mid-cycle

A brief motor cutout followed by automatic recovery is a BMS overcurrent trip, not a battery failure. It happens when the Conga encounters a sustained restriction — dense carpet, a clogged intake, or a jammed brush roll — that forces the motor to pull beyond the BMS current threshold. The BMS trips the output, the restriction clears (or the robot moves off the carpet), and power restores. Check the intake and brush compartment for hair or debris matted tightly enough to stall rotation, and confirm the filter is seated correctly before attributing the fault to the replacement cell.
