It matches OEM part numbers 3027689, BHR4307GL, P2046-7S1P-BCA, P2046-7S1P-BCB, and V2209-7S1P-BCA. Capacity figures are taken directly from our product specifications, not estimated from third-party sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDreame G9 \/ T10 \/ T20 \/ P2010 platform:\u003c\/strong\u003e\n    These models share the same 25.2V seven-cell architecture, connector pinout, and BMS handshake protocol. One battery pack serves the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a Dreame G9 unit. The BMS communicated correctly with the charger, accepted a full charge without error codes, and delivered consistent voltage across load cycles at both standard and MAX suction modes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the dock permanently between uses. Continuous dock charging subjects Li-ion cells to low-level trickle stress that accelerates capacity fade. Charge to full, remove from the dock, and store the vacuum off the charger.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCordless vacuum losing suction 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 at its present state of charge. A partially blocked filter forces the motor to work harder, pulling amps above the rated draw and triggering the BMS to reduce output voltage before the indicator registers low. The result is noticeable suction loss while the battery display still shows two or three bars. Clean or replace the HEPA filter first — if suction recovers, the battery is not the fault. If suction remains weak with a clean filter on a new pack, check that the voltage at the pack terminals reads at or above 22V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then restarts after a few seconds\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a flat battery. It occurs when sustained restricted airflow — from a blocked filter, full dust bin, or blocked floor head — forces the motor into a high-current stall state. The BMS detects current above its trip threshold and cuts the output circuit to protect the cells. After a few seconds the BMS resets and the motor restarts. Clear the blockage and empty the bin before the next run. If the cutout persists on an unblocked machine, check whether the pack recovers to 25.2V on a full charge cycle — a cell that cannot hold full charge will hit the BMS trip threshold faster under any load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427984441434,"sku":"BWCS-XMT100VX-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427984474202,"sku":"BWCS-XMT100VX-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427984506970,"sku":"BWCS-XMT100VX-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMT100VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/xiaomi-dreame-g9-replacement-battery-252v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
