It replaces OEM part numbers BVBOP03108501EU and FBP092. The battery slots into the original housing and connects to the same BMS interface as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3598Z and Crosswave HF3 compatibility:\u003c\/strong\u003e\n    Both models run the same 22.2V battery rail with an identical connector and BMS handshake protocol. A single cell pack fits either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge cycles on the Crosswave HF3 dock. The BMS held stable voltage under sustained motor load, and the protection circuit triggered correctly on simulated overcurrent — no false cutoffs during normal suction cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for the Crosswave HF3:\u003c\/strong\u003e\n    The Crosswave HF3 charging dock applies a trickle current after the pack reaches full charge. Leaving the vacuum on the dock permanently accelerates cell degradation. Charge to full and remove the unit 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\"\u003eThe 3598Z motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. This increased draw pulls the cell voltage below the BMS threshold before the indicator registers as low, causing the motor to slow and suction to fall. The battery itself is not the root cause in this scenario. Clean the filter and clear the brush roll — if suction restores immediately, the cell voltage should recover above 20V at rest.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the vacuum runs against a heavy carpet pile or through a blockage, current draw spikes sharply and the BMS shuts the output to protect the cells. After a brief pause the BMS resets and power returns. If this happens repeatedly in the same cleaning session, check the filter — a clogged filter forces the motor to work harder and repeat the trip cycle. Replace or wash the filter and retest before assuming the battery is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426375565402,"sku":"BWCS-BSF300VX-1","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426375598170,"sku":"BWCS-BSF300VX-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426375630938,"sku":"BWCS-BSF300VX-3","price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSF300VX_1.webp?v=1779931068","url":"https:\/\/batteryweb.com\/products\/bissell-3598z-replacement-battery-222v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
