It replaces the OEM pack when original capacity has dropped or the cell has failed entirely. The physical dimensions — 91.60 x 68.60 x 47.30mm — match the original battery bay on these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColombina XLR18 series compatibility:\u003c\/strong\u003e\n    All Colombina XLR18 variants share the same 18.5V power rail and battery connector format. The BMS in each model communicates through the same contact arrangement, so the pack seats and handshakes the same way across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through load testing on a Colombina unit under both light-surface and high-restriction conditions. The BMS held discharge cut-off correctly and did not trip falsely during normal suction loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Colombina vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Colombina units on continuous dock charge develop capacity fade faster than those charged only when the battery is depleted. Charge fully, then remove from 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\"\u003eThis happens when the motor draws more current than the BMS expects under a restricted airflow condition — a partially blocked filter is the most common trigger. As resistance increases, the motor pulls harder, voltage sags under load, and the BMS throttles output before the indicator registers a low charge state. The indicator reads cell voltage at rest, not under load, so it lags behind what the motor actually experiences. Clean or replace the filter first; if suction recovers, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is an overcurrent trip from the BMS, not a dead battery. When suction is restricted — blocked filter, jammed brush roll, or a sealed nozzle against a surface — the motor stalls momentarily, current spikes, and the BMS disconnects the output to protect the cells. After a short rest, the BMS resets and the vacuum starts again. Check the filter and brush roll for blockages before concluding the battery is at fault. If the motor cuts out on an unobstructed surface, measure pack voltage under load — it should hold above 16V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428003741786,"sku":"BWCS-CXR180VX-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428003774554,"sku":"BWCS-CXR180VX-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428003807322,"sku":"BWCS-CXR180VX-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CXR180VX-1.webp?v=1779933823","url":"https:\/\/batteryweb.com\/products\/delonghi-colombina-xlr18lm-replacement-battery-185v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
