It uses OEM part number XBP736 and drops into the same battery bay as the original. When the factory pack can no longer drive the motor through a full cleaning session, this cell restores full operating voltage to the vacuum.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSV736 series compatibility:\u003c\/strong\u003e\n    The SV736, SV736R, SV70Z, and SV736N all run the same 15.6V power rail, use the same battery bay geometry, and share the same BMS handshake protocol. One cell covers the entire line.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through motor-start cycles on the SV736 platform. The BMS handled the inrush current on carpet mode without tripping, and cell voltage held stable across sustained suction draws.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on SV736:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock indefinitely after it reaches full charge. Continuous trickle current accelerates capacity loss in Ni-MH cells faster than in Li-ion packs. 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\"\u003eNi-MH cells under a restricted airflow load — clogged filter, tangled brush roll — draw more current than the motor circuit expects. Voltage sags under that elevated draw, and suction weakens well before the indicator registers a low-battery state. The battery is not at fault; the motor is working harder than rated to pull air through a restriction. Clear the filter and brush roll, then retest. If suction restores immediately, the pack is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is blocked — full dustbin, compressed filter, or a floor seal against the nozzle — the motor spikes current draw beyond the BMS threshold. The BMS cuts power to protect the cell, waits for the current to drop, then re-enables the circuit. The recovery pause is the BMS reset timer completing. Empty the dustbin, tap the filter clean, and confirm the nozzle is not sealed flat against the floor before restarting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428059152474,"sku":"BWCS-ESV736VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428059185242,"sku":"BWCS-ESV736VX-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428059218010,"sku":"BWCS-ESV736VX-3","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ESV736VX-1.webp?v=1779934015","url":"https:\/\/batteryweb.com\/products\/shark-sv736-replacement-battery-156v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
