It also fits the ZB 3011, ZB 3012, and ZB3012 series. The battery replaces OEM part numbers VBHC7787E, 8087979053, 809115702, 140127175473, and related variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eErgorapido ZB30-series compatibility:\u003c\/strong\u003e\n    The ZB 3011, ZB 3012, and Ergorapido Plus share the same 18V battery bay, connector orientation, and BMS communication protocol — one cell fits all of them 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 repeated motor start and sustained-run sequences on the ZB3012. The BMS held voltage within spec across normal floor and carpet loads, and overcurrent cutoff triggered correctly under a simulated blockage event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on Ergorapido vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Ergorapido docks do not cut trickle current once full, and continuous low-level charging accelerates cell degradation. Charge to full, then remove the vacuum 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 is a voltage sag issue, not a capacity issue. When the filter is partially blocked, the motor draws more current than rated to maintain airflow, pulling cell voltage down early. The BMS reads that voltage drop and begins throttling motor power — which you experience as reduced suction even with charge still showing. Clean the filter first; if sag continues on a clean filter, the cell is fatigued and needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is the BMS tripping an overcurrent cutoff, not a loose connection. It happens when sustained restricted airflow — from a clogged filter or blocked nozzle — forces the motor to spike current above the BMS threshold. The BMS shuts down the output to protect the cells, then resets once current demand drops. Clear the filter and nozzle, then check that resting voltage on the battery is at or above 16V before continuing use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428008820826,"sku":"BWCS-ELT320VX-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428008853594,"sku":"BWCS-ELT320VX-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428008886362,"sku":"BWCS-ELT320VX-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELT320VX-1.webp?v=1779933824","url":"https:\/\/batteryweb.com\/products\/electrolux-ergorapido-plus-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
