It fits the Z-PD1200, PD1200 H1, Flexi PD1080 H2, and the Dustbuster Flexi Cyclonic Action range, among others. OEM part number 90584779 confirms the correct connector and BMS configuration for these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlexi and Dustbuster platform fit:\u003c\/strong\u003e\n    These models share the same 12V cell pack geometry, connector pinout, and BMS handshake requirements. A single replacement covers the full range listed above without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated charge and discharge runs on the Z-PD1200 platform. The BMS held steady through motor-start current spikes and did not trip under normal suction load on a clear filter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on Flexi vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock after the battery reaches full. Ni-MH cells in continuous trickle charge degrade faster 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\"\u003eThis happens under motor voltage sag — not a dead battery. When the filter is partially blocked, the motor draws more current than its rated load. Voltage drops faster than the indicator registers, and suction falls off while the indicator still reads mid-charge. Clean or replace the filter first. If suction recovers, the battery is fine and the filter was the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then comes back on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure. Sustained restricted airflow forces the motor to pull above its normal current draw. The BMS trips to protect the cell pack and resets once temperature drops. Clear any blockage in the nozzle or filter. If the motor still trips on a clean filter, check that the replacement pack voltage reads at least 12.0V under load before assuming a faulty cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428015243354,"sku":"BWCS-BKD120VX-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428015276122,"sku":"BWCS-BKD120VX-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428015308890,"sku":"BWCS-BKD120VX-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKD120VX-1.webp?v=1779933824","url":"https:\/\/batteryweb.com\/products\/blackdecker-z-pd1200-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
