It restores suction power when the original battery has faded or failed. Capacity figure is taken directly from product data at 97.92Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e34264 \/ BHR5195EU platform fitment:\u003c\/strong\u003e\n    These models share a common 14.4V four-cell series architecture and use the same connector pinout and BMS communication protocol — that is why one replacement covers all three fit models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through charge and discharge cycles on the Mi Robot Vacuum-Mop 2 Ultra platform. The BMS held stable cutoff voltage under simulated floor-cleaning load and recovered cleanly from the motor-start current draw without tripping overcurrent protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for Mi Robot Vacuum models:\u003c\/strong\u003e\n    Do not leave this vacuum parked on its charging dock permanently. Continuous dock contact keeps the cells in a trickle-charge state that degrades capacity faster than normal cycling. Charge the battery to full, then break dock contact until the next clean.\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\"\u003eThe Mi Robot Vacuum-Mop 2 Ultra measures battery state by resting voltage, not under-load voltage. When a filter is partially blocked or the brush roll is restricted, the motor draws above its rated current. Voltage sags under that elevated draw, but the indicator — reading a brief resting voltage — still shows mid-charge. The fix is mechanical: clean the HEPA filter and clear the brush roll, then retest. If suction recovers, the battery was never the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. Sustained restricted airflow — from a clogged filter or a blocked intake — forces the motor to pull current beyond the BMS threshold, triggering a temporary shutdown. The BMS resets after a short cooldown, which is why the vacuum restarts by itself. Clear the filter and intake path, then verify the resting pack voltage sits above 13.0V before running another cleaning cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426391916634,"sku":"BWCS-XMP520VX-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426391949402,"sku":"BWCS-XMP520VX-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426391982170,"sku":"BWCS-XMP520VX-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMP520VX-1.webp?v=1779931232","url":"https:\/\/batteryweb.com\/products\/xiaomi-34264-replacement-battery-144v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
