It replaces the original pack when the cell group degrades and the vacuum can no longer hold a usable charge. Dimensions are 117 x 103 x 76mm — verify against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSVC 8618GD compatibility:\u003c\/strong\u003e\n    The SVC 8618GD runs its brushless motor directly off the 18V cell pack. The BMS in this replacement matches the voltage rail and discharge curve the motor controller expects, so the vacuum powers on and runs at full suction from the first charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the SVC 8618GD platform. The BMS handled sustained motor draw without nuisance tripping, and cell balance across the pack stayed within spec through repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on this vacuum:\u003c\/strong\u003e\n    Do not leave the SVC 8618GD sitting on its charging dock permanently. Continuous trickle current accelerates capacity fade on Li-ion packs faster than normal use. Charge to full, remove from the dock, and reconnect only when the pack is depleted.\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 on the SVC 8618GD\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws harder than normal — usually because the filter is partially blocked. Under restricted airflow, current demand spikes and the BMS pulls back discharge current to protect the cells, which the motor reads as a low-voltage condition. The vacuum loses suction even though the pack still has capacity remaining. Clean or replace the filter first, then retest — if suction holds across a full cycle, the pack is fine and the filter was the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-session 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 suction is restricted — blocked nozzle, dirty filter, or heavy carpet load — the motor draws a sustained current spike above the BMS threshold. The protection circuit opens, the motor stops, and after 30–60 seconds the BMS resets and the vacuum runs again. Fix the restriction first. If cutouts continue on a clear filter at a normal surface, check that pack voltage under load reads above 15V — below that, the cells are fatigued and the pack needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426481995866,"sku":"BWCS-SVC862VX-1","price":510.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426482028634,"sku":"BWCS-SVC862VX-2","price":610.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426482061402,"sku":"BWCS-SVC862VX-3","price":685.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVC862VX-1.webp?v=1779933389","url":"https:\/\/batteryweb.com\/products\/sencor-svc-8618gd-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
