DeLonghi Colombina EVO 25.9V Replacement Battery AS00000910

DeLonghi Colombina EVO / XML510 — 25.9V Li-ion Replacement Battery (AS00000910)

This 25.9V 2500mAh Li-ion battery replaces OEM part AS00000910 in the DeLonghi Colombina EVO and XML510 cordless stick vacuums. It fits directly into the vacuum's battery bay and runs the brushless motor circuit at the correct voltage rail. Use this when the original cell no longer holds a charge or the vacuum shuts off early in a cleaning session.

• Colombina EVO and XML510 compatibility: Both models share the same 25.9V battery platform, connector layout, and BMS handshake protocol. A single replacement cell covers either unit without modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Colombina EVO motor circuit. The BMS responded correctly to both low-voltage cutoff and overload events — no false trips under normal suction load.
• Dock charging habit on cordless vacuums: Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charging degrades Li-ion cells faster than any other single factor on this device class. Charge to full, then remove from the dock until the next use.

Suction dropping before the battery indicator reaches low

On the Colombina EVO, suction loss before the battery LED signals low is almost always a motor voltage sag issue, not a capacity problem. When the filter is partially blocked, the motor draws more current than rated to maintain airflow, which triggers a voltage sag across the battery terminals. The BMS reads this as a near-depleted cell and throttles motor output. Clean the filter first — if suction recovers after a filter clear, the battery is not the cause.

Motor cuts out mid-clean and then recovers on its own

This is a BMS overcurrent trip, not a failed battery. When sustained suction restriction forces the motor to pull beyond the BMS current threshold — typically triggered by a blocked filter or nozzle — the protection circuit disconnects the output to prevent cell damage. The trip resets automatically once current demand drops, which is why the vacuum restarts after a short pause. Check and clear the filter, then inspect the nozzle for a blockage before concluding the battery is faulty. If trips continue on a clean filter, check that the cell terminal voltage reads at or above 22V before charging.
