It fits the XLM353.ADC, XLM355.ADC, XLM403.GDC, and additional variants that share the same battery slot and voltage rail. Capacity is 2000mAh (43.2Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColombina Evo Pro series fit:\u003c\/strong\u003e\n    These models share a common 21.6V architecture, connector format, and BMS handshake protocol. The battery communicates with the vacuum's control board to regulate discharge rate and trigger motor protection — the replacement cell carries the same BMS logic so the board recognises it without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the Colombina Evo Pro platform. The BMS responded correctly to motor load spikes, cut off cleanly at low-voltage threshold, and accepted charge without rejection from the dock charger.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for this vacuum:\u003c\/strong\u003e\n    Do not leave the Colombina Evo Pro sitting on the charging dock between every use. Li-ion cells in this pack degrade faster under continuous trickle charge than under normal charge-and-remove cycles. Charge to full, then pull it off the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Colombina Evo Pro's motor draws significantly more current when airflow is restricted — a partially blocked filter can push draw well above the rated load. When current spikes, the BMS reduces output voltage to protect the cells, and the motor slows before the indicator has time to reflect the actual charge state. The battery gauge reads the resting voltage, not the loaded voltage under restriction. Clean the filter first — if suction recovers and holds, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a power failure. When the vacuum hits a blockage or runs over thick carpet with a clogged filter, current draw exceeds the BMS protection threshold and the pack shuts off the output rail. After a few seconds the BMS resets and the motor comes back. The fix is airflow — clear any blockage, check the filter, and confirm the dust container is not full. If the problem persists with a clean filter and clear path, measure the pack voltage under load; it should hold above 19V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427955343450,"sku":"BWCS-ELT521VX-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427955376218,"sku":"BWCS-ELT521VX-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427955408986,"sku":"BWCS-ELT521VX-3","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELT521VX-1.webp?v=1779933419","url":"https:\/\/batteryweb.com\/products\/delonghi-colombina-evo-pro-replacement-battery-216v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
