It fits the SV745 handheld unit directly, using the OEM part number XBP745. Replace it when suction has dropped noticeably and the original cell no longer holds a full charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSV745 fitment:\u003c\/strong\u003e\n    The SV745 runs a 12V Ni-MH cell with a specific connector and BMS communication path. This replacement matches that voltage rail and connector, so the vacuum's charge detection circuit recognises the cell correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on the SV745 platform. The BMS accepted the cell without a fault flag, and motor draw sat within the rated current range throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the SV745:\u003c\/strong\u003e\n    Do not leave the SV745 sitting on the charging dock permanently. Continuous trickle charge on Ni-MH cells causes capacity fade faster than normal use. Charge to full, 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\"\u003eA partially blocked filter forces the SV745 motor to draw more current than rated. That extra draw causes voltage sag in the Ni-MH cell, and the motor loses speed before the charge indicator shows anything wrong. The vacuum feels like a battery fault, but the battery is not the cause. Clean or replace the filter first — if suction returns immediately, the cell is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSV745 motor cutting out mid-clean and then recovering\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the SV745 runs sustained suction against a blockage or a clogged filter, current draw spikes and the BMS interrupts power to protect the cell. The motor recovers after a few seconds once current normalises. Check the filter and the inlet path for blockages before assuming the battery is failing — the cutout at that stage typically means restricted airflow, not a worn cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428020846682,"sku":"BWCS-SHV745VX-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428020879450,"sku":"BWCS-SHV745VX-2","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428020912218,"sku":"BWCS-SHV745VX-3","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHV745VX-1.webp?v=1779933917","url":"https:\/\/batteryweb.com\/products\/shark-sv745-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
