It slots directly into the same battery compartment as the OEM cell and uses the same BMS communication expected by the charger. Rated capacity is 2000mAh (14.8Wh) — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBDCD8GPA-QW, G9L72+, HNVC215B, HNVC220B compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V two-cell Li-ion architecture, identical connector housing, and the same BMS handshake protocol — which is why one replacement cell covers the entire platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the HNVC dock and monitored BMS cutoff thresholds under simulated motor load. The protection circuit engaged correctly at both the over-current and low-voltage limits without triggering false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on these vacuums:\u003c\/strong\u003e\n    Do not leave the HNVC or BDCD8 on the charging dock continuously. These vacuums lack active charge termination on the dock side — the BMS handles it, but trickle voltage over days accelerates cell degradation. Charge to full, then remove.\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\n  \u003cp class=\"bpw-desc-p\"\u003eOn the HNVC series, the battery indicator reads cell voltage — not remaining capacity under load. When the filter is even partially blocked, the motor draws above its rated current. Voltage sags faster than the indicator expects, so suction weakens while the LED still shows adequate charge. This is not a battery fault. Clean the filter first, then re-test suction consistency across a full charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead cell. When sustained suction restriction forces the motor to pull current above the BMS cutoff threshold, the protection circuit opens and power drops. The BMS resets after a brief cool-down period — which is why the vacuum appears to recover on its own. Fix the restriction first: clear the inlet, wash the filter, and confirm airflow is unobstructed before attributing the fault to the battery. If trips continue on a clear filter, measure cell voltage at rest — it should read above 7.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426419408986,"sku":"BWCS-BDC215VX-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426419441754,"sku":"BWCS-BDC215VX-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426419474522,"sku":"BWCS-BDC215VX-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BDC215VX-1.webp?v=1779933186","url":"https:\/\/batteryweb.com\/products\/blackdecker-bdcd8gpa-qw-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
