It also covers models 90027882501 and 90027881001, plus eight additional variants sharing the same voltage rail and connector. Capacity matches the product data: 2000mAh \/ 59.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCX8 platform compatibility:\u003c\/strong\u003e\n    The CX8 series runs a common 29.6V architecture across both floor and handheld configurations. The battery connector and BMS handshake are identical across these variants, so one pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a CX8-2-75FF unit and logged the BMS response through motor start, sustained suction, and low-battery cutoff. The BMS held correct cutoff thresholds and did not trip on normal carpet load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the CX8:\u003c\/strong\u003e\n    Do not leave the vacuum permanently seated on the charging dock. Continuous dock charging causes capacity fade faster than intermittent use cycles. Charge to full, then remove the vacuum from the dock until the next use.\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\"\u003eOn CX8 vacuums, the motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. The BMS reads this spike as a high-draw event and throttles output voltage to protect the cells — even when charge level appears normal. The vacuum loses suction noticeably before the indicator signals low battery. Clean the filter and check the brush roll for blockage first; if suction recovers immediately, the battery is not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCX8 motor cuts out mid-use, then restarts after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. It happens when sustained restricted airflow forces the motor to pull above the pack's rated current limit. The BMS shuts the circuit, waits for the cell temperature to settle, then resets automatically. To stop it recurring, clear the filter, check for blockages in the dust path, and ensure the post-motor filter is not saturated. If trips continue on a clear vacuum, check cell resting voltage — a healthy pack at partial charge should sit above 25V open circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427966025818,"sku":"BWCS-AEC826VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427966058586,"sku":"BWCS-AEC826VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427966091354,"sku":"BWCS-AEC826VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AEC826VX-1.webp?v=1779933519","url":"https:\/\/batteryweb.com\/products\/aeg-cx8-2-75ff-replacement-battery-296v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
