It fits models including the Robotics D8 and Botvac D9, replacing OEM parts 945-0381, 945-0376, 945-0382, 205-0023, 205-0021, 205-0026, and 205-0022. Swap it in when the original cell has degraded and the robot can no longer complete a full cleaning cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD8 and D9 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 14.4V motor rail, and BMS communication protocol. One 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, discharge, and reinsertion on a D9 unit. The BMS handshake completed correctly, the charge indicator responded as expected, and the vacuum returned to normal navigation without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the D8 and D9:\u003c\/strong\u003e\n    Do not leave the robot sitting on the charging dock permanently between uses. Continuous trickle charge on these models accelerates capacity fade faster than scheduled charge-and-remove cycles. Charge to full, then lift it off the dock 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 D8 and D9 motors draw significantly more current when airflow is restricted — a clogged filter or partial blockage forces the motor to work harder, pulling the cell voltage down earlier than the battery indicator reflects. The indicator reads state of charge, not voltage under load, so suction loss appears before any low-battery warning. Under that elevated draw, the BMS may begin throttling motor output to protect the cell even though the display still shows adequate charge. Check and clean the filter first — if suction recovers immediately after cleaning, the battery is not the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery fault in isolation. When the robot hits dense carpet or a sustained blockage, current draw spikes beyond the BMS protection threshold and the cell disconnects momentarily. The BMS resets once current demand drops, which is why the motor restarts on its own. A degraded original battery hits that threshold sooner because internal resistance rises with age, amplifying the voltage sag under load. After fitting this replacement, confirm the filter is clear and the brush roll spins freely — those two restrictions account for most repeat trips.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427975069786,"sku":"BWCS-NVD100VX-1","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427975102554,"sku":"BWCS-NVD100VX-2","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427975135322,"sku":"BWCS-NVD100VX-3","price":145.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NVD100VX-1.webp?v=1779933649","url":"https:\/\/batteryweb.com\/products\/neato-d8-replacement-battery-144v-6800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
