It fits the 3789, 3789U, and 3797W models, among others. Swap it in when the original cell no longer holds enough charge to complete a cleaning session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCleanview XR platform fit:\u003c\/strong\u003e\n    The 3789, 3789U, and 3797W share the same 24V battery rail, connector pinout, and BMS handshake protocol — one cell covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Cleanview XR charging cycle and confirmed the BMS communicates correctly with the dock, holds the full 24V nominal charge, and releases current cleanly under motor start load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock removal after full charge:\u003c\/strong\u003e\n    The Cleanview XR dock does not terminate charge aggressively once full. Leave the battery on the dock indefinitely and the trickle current degrades cell capacity noticeably within months. 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\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is drawing more current than rated, usually because the filter is partially blocked. A restricted airflow path forces the motor to work harder, which pulls the cell voltage down faster than the indicator expects. The BMS reads the voltage drop as normal load and doesn't flag a warning, but real capacity is being consumed faster than the display shows. Clean or replace the foam and post-motor filters before swapping the battery — a new cell will show the same behaviour on a clogged machine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction — from a blockage or a saturated filter — pushes draw above the cell's continuous current limit, the BMS cuts the output to protect the cells. After a few seconds the BMS resets and power returns. The fix is to clear the blockage or clean the filter, not to replace the battery. If the trip happens repeatedly on an unblocked machine with a new filter, check that the cell voltage at rest is at or above 21.6V before suspecting the battery itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426425110618,"sku":"BWCS-BSR379VX-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426425143386,"sku":"BWCS-BSR379VX-2","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426425176154,"sku":"BWCS-BSR379VX-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSR379VX-1.webp?v=1779933187","url":"https:\/\/batteryweb.com\/products\/bissell-3789-replacement-battery-24v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
