It fits directly into both models and restores full motor voltage to the cleaning head. Capacity matches the factory spec at 3400mAh (37.74Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXJC-Y010 and XJB-B021 compatibility:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell series configuration and share the NCR1650-3S1P pack format, connector orientation, and BMS communication protocol — so one battery covers both platforms 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 full charge and discharge cycles on the XJC-Y010 motor assembly. The BMS handled start-up current draw without tripping, and cell balance stayed within spec across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the XJC-Y010:\u003c\/strong\u003e\n    These vacuums are often left sitting on the charging cradle between uses. The BMS does not fully interrupt charge current when the pack reaches capacity — continuous trickle input accelerates cell degradation faster than normal cycle wear. Charge to full, then remove from the dock.\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 XJC-Y010 motor draws higher current when the filter is partially blocked — the fan has to work harder to pull the same airflow. This elevated draw causes voltage to sag across the cells before the indicator registers a low charge state. The vacuum feels like it's losing power early, but the battery isn't the only factor. Clean or replace the filter first, then test under normal load — if suction holds steady, the pack was compensating for a restriction, not failing on its own.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor fault. When sustained suction is restricted — blocked filter, clogged nozzle, or dense carpet — current draw spikes past the BMS threshold and the pack disconnects to protect the cells. The battery recovers once temperature and load drop, which is why the vacuum restarts after a pause. Clear the blockage, check the filter is seated correctly, and confirm the pack rests at 12.4V or above before the next use — a low starting voltage tightens the margin before the BMS trips again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427992830042,"sku":"BWCS-PMX021VX-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427992862810,"sku":"BWCS-PMX021VX-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427992895578,"sku":"BWCS-PMX021VX-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMX021VX-1.webp?v=1779933754","url":"https:\/\/batteryweb.com\/products\/plus-minus-zero-xjc-y010-replacement-battery-111v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
