It replaces OEM part XB780N and restores power to the vacuum motor when the original cell no longer holds a charge. Voltage and capacity match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSV780N motor rail compatibility:\u003c\/strong\u003e\n    The SV780N runs a brushed DC motor on a 16.8V Ni-MH rail. Ni-MH chemistry delivers a flat discharge curve that matches what the motor controller expects across the full charge cycle — a Li-ion substitution at the same nominal voltage would not replicate the same discharge profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence on the SV780N platform. The BMS accepted the charge handshake without fault, and the motor drew consistently across the discharge curve without triggering a protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the SV780N:\u003c\/strong\u003e\n    Do not leave the SV780N sitting on its charging dock permanently. Ni-MH cells on continuous trickle charge degrade faster than cells charged only when depleted. 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\"\u003eThis happens when the motor is working harder than rated — usually because of a restricted filter or partial blockage. The motor draws more current to maintain suction, which pulls the cell voltage down faster than the indicator circuit expects. The vacuum appears to lose power early, but the battery is not always the cause. Check and clean the filter before replacing the cell — a clean filter brings motor draw back within the normal range the battery can sustain.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked nozzle, clogged filter, or carpet fibres packed into the brush roll — the motor draws a sustained high current spike the BMS reads as a fault and shuts the output. The cell recovers once the protection timer resets, which is why the vacuum starts again after a short wait. Clear the blockage first. If cutouts continue on an unobstructed path with a clean filter, the original cell's internal resistance has risen too high to handle normal motor-start current — replace the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428046602330,"sku":"BWCS-EXV870VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428046635098,"sku":"BWCS-EXV870VX-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428046667866,"sku":"BWCS-EXV870VX-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EXV870VX-1.webp?v=1779933939","url":"https:\/\/batteryweb.com\/products\/euro-pro-shark-sv780n-replacement-battery-168v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
