It slots into the battery compartment and communicates with the robot's onboard BMS using the same handshake protocol as the original cell pack. Capacity is 5200mAh (74.88Wh) — taken from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAED03HRR \/ AED04HRR and extended model range:\u003c\/strong\u003e\n    These Roborock models share the same 14.4V battery rail, connector pinout, and BMS communication protocol. The replacement cell pack fits across all of them without modification to the housing or charging contacts.\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 Roborock hardware and confirmed the BMS handshake initialised correctly — the robot accepted the battery without faulting, and the charge indicator reported state-of-charge accurately throughout the cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this robot:\u003c\/strong\u003e\n    Do not leave the Roborock on the charging dock permanently between cleaning sessions. Continuous dock contact applies a trickle charge that degrades Li-ion cell capacity measurably faster than charge-and-remove cycles. Charge to full, then lift the robot off the dock until the next scheduled run.\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 battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn Roborock units with a partially blocked filter or brush roll restriction, the motor draws more current than the rated load. The BMS reads that elevated draw as a voltage sag and throttles output to protect the cells — the robot slows or loses suction power while the indicator still shows a mid or high charge state. The battery is not the fault here. Clean the filter and clear the brush roll, then retest. If suction restores at the same charge level, the cell pack is functioning correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRobot stops mid-cycle, pauses, then resumes on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis stop-pause-resume pattern is a BMS overcurrent trip, not a dead battery. When the motor sustains a high-draw state — usually from a blocked suction path or tangled brush roll — the BMS cuts output to prevent cell damage, then resets once current normalises. The robot reads this as an error pause rather than a low-battery event. Clear any obstruction, check that the filter is seated correctly, and confirm the brush roll spins freely. If the issue stops after cleaning, the battery is intact — measure resting voltage after a full charge and confirm it holds above 16.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427981983834,"sku":"BWCS-XMT400VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427982016602,"sku":"BWCS-XMT400VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427982049370,"sku":"BWCS-XMT400VX-3","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMT400VX-1.webp?v=1779933696","url":"https:\/\/batteryweb.com\/products\/roborock-aed03hrr-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
