It replaces the original cell pack that powers the vacuum motor across all standard cleaning tasks — floors, carpet, and upholstery. Capacity is 2000mAh (28.8Wh), matching the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSVC 9020 and 9031 platform compatibility:\u003c\/strong\u003e\n    Both the 9020 and 9031 variants run the same 14.4V motor rail and share the same physical battery housing dimensions (91.91 × 67.35 × 44.58mm). The cell count and pack voltage are identical across the colour variants, so one replacement covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and load discharge on a 14.4V motor draw. The BMS held within spec under sustained suction load, and cell voltage stayed balanced across the Ni-MH array through multiple cycles without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on Ni-MH vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum on the charging dock permanently. Ni-MH cells in cordless vacuums develop capacity fade significantly faster under continuous trickle charge than cells charged only when depleted. 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 load show a voltage curve that drops sharply when a restricted airflow path forces the motor to draw above its rated current. On the SVC 9020 and 9031, a clogged filter or partial blockage can trigger this before the indicator registers a low state. The motor pulls harder against the restriction, the cell voltage sags, and the vacuum loses suction — even though the battery still holds charge. Clear the filter and check the inlet path first; the indicator is calibrated for unobstructed draw, not restricted operation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean, 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 sustained suction restriction raises current draw past the pack's protection threshold, the BMS opens the circuit to prevent cell damage. The pack recovers once current demand drops — which is why a short pause brings the vacuum back. Check the filter and inlet for blockage before replacing the battery. If the cutout happens with a clean filter and clear airflow, measure resting pack voltage; a healthy 14.4V Ni-MH pack at full charge should read at or above 16.8V across the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428069277786,"sku":"BWCS-KSB001VX-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428069310554,"sku":"BWCS-KSB001VX-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428069343322,"sku":"BWCS-KSB001VX-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KSB001VX_1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/pro-modely-svc-9020-bk-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
