It slots into the DK600's battery bay and restores full suction power after the original cell has degraded. No OEM part number is published for this unit — fit is confirmed by model number and physical dimensions (69.40 × 37.00 × 37.00mm).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDK600 platform fit:\u003c\/strong\u003e\n    The DK600 runs a 14.4V cell rail with a compact rectangular pack. This replacement matches that voltage, physical footprint, and connector orientation. The onboard BMS communicates charge state to the vacuum's indicator circuit — swapping to a mismatched voltage breaks that signal and triggers a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under sustained motor load and confirmed the BMS holds voltage above the DK600's low-cell cutoff through repeated draw cycles. The protection circuit trips correctly on overcurrent, then resets without requiring a full power cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for the DK600:\u003c\/strong\u003e\n    The DK600 charging dock does not stop trickle charging once the cell reaches full. Leave the vacuum on the dock between every use and the Li-ion cells develop capacity fade within months. Charge to full, then remove from the dock until the next cleaning session.\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 hits low on the DK600\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DK600's motor draws significantly more current when airflow is restricted — a partially blocked filter can push draw past the BMS's sustained-current threshold before the battery is anywhere near depleted. The BMS reads this spike as a low-voltage event and throttles output, which feels like battery fade but isn't. Clean the filter first. If suction restores immediately after filter cleaning, the cell is not the issue. If suction still drops on a clean filter, measure pack voltage under load — a healthy 14.4V cell should hold above 12.5V during active use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDK600 motor cutting out mid-clean and then recovering on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed motor. When the vacuum runs over dense carpet or picks up a blockage, instantaneous current demand spikes sharply. If the BMS sees that spike exceed its threshold, it cuts the output circuit to protect the cells — the motor stops, then restarts once the BMS resets, usually within a few seconds. Check the suction path for partial blockages first, including the brush roll and inlet. If the cutouts continue on a clear airway, the original battery's cells have degraded enough that internal resistance is amplifying the voltage sag — a replacement cell at full capacity resolves this.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428006232154,"sku":"BWCS-TVR500VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428006264922,"sku":"BWCS-TVR500VX-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428006297690,"sku":"BWCS-TVR500VX-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TVR500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/denkee-dk600-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
