It slots into the battery compartment of the original unit and restores the power supply that drives the cleaning motor and navigation system. Capacity is 3000mAh (43.2Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRobby, Robby Deluxe, and Robby Home XR compatibility:\u003c\/strong\u003e\n    All three models share the same 14.4V battery platform, connector format, and BMS communication protocol. A single cell covers the full range without modification.\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 Robby unit. The BMS accepted the cell without fault codes, current draw tracked within spec across both carpet and hard floor modes, and charge termination triggered correctly at capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for Ni-MH cells:\u003c\/strong\u003e\n    Do not leave the Robby sitting on the charging dock indefinitely between uses. Ni-MH chemistry is sensitive to continuous trickle charge — charge the battery to full, then remove it from the dock. Return it to the dock only when the unit needs a full cycle.\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\"\u003eNi-MH cells deliver a relatively flat discharge curve, so the onboard indicator often lags behind actual cell voltage under load. When the motor draws sustained current — especially over thick carpet or a partially blocked filter — cell voltage sags faster than the indicator registers. The result is audible suction loss while the indicator still shows adequate charge. If the filter is clear and suction still drops early, the cell is no longer holding its rated capacity and replacement is the correct fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out and recovering mid-clean\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a cell failure. When airflow is restricted — blocked filter, full dust bin, or a tangled brush roll — the motor draws more current than the BMS threshold allows, and it shuts the output to protect the cell. The unit recovers once the BMS resets, usually within a few seconds. Clear the filter and brush roll first. If the cutout continues on a clean filter with a new battery, check whether the brush roll is binding mechanically.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428053942362,"sku":"BWCS-IRB410VX-1","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428053975130,"sku":"BWCS-IRB410VX-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428054007898,"sku":"BWCS-IRB410VX-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB410VX-1.webp?v=1779933966","url":"https:\/\/batteryweb.com\/products\/ambrogio-robby-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
