It replaces OEM part number G9BP-01 when the original cell loses charging capacity or stops holding charge. Fits the same connector and slot as the factory battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG9, G9 Plus, and G9 Pro compatibility:\u003c\/strong\u003e\n    All three models share the same 22.2V power rail, connector configuration, and BMS handshake protocol — that is why one battery covers the entire G9 range. Swapping between G9 variants does not require any firmware change or charger swap.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a G9 chassis. The BMS held steady voltage through both hard floor and carpet motor loads, with overcurrent protection tripping correctly when suction was deliberately blocked at the nozzle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave the G9 sitting on the charging dock permanently. Continuous dock contact keeps the cell in a trickle charge state that accelerates capacity fade. Charge to full, then remove the vacuum from the dock until the next use.\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\"\u003eOn the G9, suction loss is often misread as a dying battery when the real cause is voltage sag under load. A partially blocked filter forces the motor to draw more current than rated, which causes the cell voltage to dip and the motor to slow — even when the indicator still shows charge remaining. Pull and clean the filter first before concluding the battery is the problem. If suction recovers after a filter clean, the cell is not at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then comes back after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. When sustained suction restriction — a blocked nozzle, full dust cup, or clogged filter — pushes motor current above the BMS threshold, the protection circuit cuts power to prevent cell damage. After a brief pause the BMS resets and the motor restarts. Clear the blockage and check the dust cup fill level. If trips continue with a clean filter and empty cup, measure resting cell voltage — it should read above 22V before placing a charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426384445530,"sku":"BWCS-MDQ910VX-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426384478298,"sku":"BWCS-MDQ910VX-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426384511066,"sku":"BWCS-MDQ910VX-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDQ910VX-1.webp?v=1779931232","url":"https:\/\/batteryweb.com\/products\/midea-g9-replacement-battery-222v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
