It slots directly into the battery compartment and connects to the existing charging circuit. Capacity is rated at 2000mAh (28.8Wh) — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDustBuster and PV1425N platform fit:\u003c\/strong\u003e\n    Both the DustBuster and PV1425N share the same 14.4V battery housing, connector pin layout, and BMS signal handshake — so one cell covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the PV1425N platform. The BMS accepted the charge signal without fault, held voltage through the full discharge curve, and tripped correctly at the low-cell threshold before the motor could stall.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for Ni-CD cells:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Ni-CD chemistry suffers measurable capacity fade from continuous trickle charging. Charge to full, remove from the dock, and return it only when the battery 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\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the cell can sustain under load — voltage sags below what the motor needs, and suction drops even though the indicator still reads mid-charge. A partially blocked filter is the most common trigger: restricted airflow forces the motor to pull harder, accelerating the voltage sag. Clean or replace the filter first, then retest suction at the start of a fresh charge. If suction is still weak with a clean filter and a full charge, the cell is fading and this replacement will restore normal draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use then recovering after a pause\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip — not a dead battery. When the motor is held under sustained restriction (blocked nozzle, clogged filter, heavy debris), current spikes past the BMS threshold and it cuts power to protect the cell. After a short pause the BMS resets and the motor starts again. Clear the nozzle and check the filter before assuming the battery is faulty. If the cutout persists with an unobstructed nozzle, measure resting voltage — a healthy Ni-CD cell should read at or above 14.4V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427953967194,"sku":"BWCS-BKV150VX-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427953999962,"sku":"BWCS-BKV150VX-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427954032730,"sku":"BWCS-BKV150VX-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKV150VX-1.webp?v=1779933419","url":"https:\/\/batteryweb.com\/products\/blackdecker-144v-dustbuster-replacement-battery-144v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
