It replaces OEM part 967813-03 directly. Use it when the original cell no longer sustains suction through a full cleaning cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDC30 \/ DC31 \/ DC34 \/ DC35 compatibility:\u003c\/strong\u003e\n    These four models share the same 22.2V battery rail, connector pinout, and BMS communication protocol — that is why one cell fits all of them. Voltage and physical form factor are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a DC35 under motor load. The BMS held steady through repeated full-suction cycles, with no overcurrent trips or thermal shutdowns recorded at normal operating draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for DC30 \/ DC35:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock continuously. These vacuums trickle-charge when left docked permanently, and that sustained low-current charge accelerates capacity loss. Charge fully and remove the unit 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\"\u003eThis happens when the motor draws more current than the BMS expects — usually because a partially blocked filter forces the motor to work harder. The BMS reads this as a voltage sag and begins throttling output before the indicator registers low. The cell is not always the cause. Clean or replace the filter first, then retest suction across a full cycle to confirm whether the battery itself is degraded.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When airflow is restricted — blocked filter, clogged cyclone, or a blockage in the bin — the motor draws a spike of current that crosses the BMS cutoff threshold. The BMS shuts the motor down to protect the cell, then resets after a short pause. Clear any blockage, clean the filter, and run again. If the cut-outs continue with a clean, unblocked machine, measure pack voltage at rest — a healthy cell at this capacity should read 24.5–25.2V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428050698330,"sku":"BWCS-DYC351VX-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428050731098,"sku":"BWCS-DYC351VX-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428050763866,"sku":"BWCS-DYC351VX-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DYC351VX-1.webp?v=1779933938","url":"https:\/\/batteryweb.com\/products\/dyson-dc30-replacement-battery-222v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
