It slots into the same battery housing and connects to the same BMS interface as the factory pack. Capacity is 2000mAh \/ 43.2Wh — matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit across the Eureka cordless range:\u003c\/strong\u003e\n    The Z0701B, SC15824N, and SC15820N platforms share the same 21.6V battery architecture, connector pinout, and BMS communication protocol — which is why a single pack covers all of them. Voltage rail and handshake are identical across this series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on the PowerPlush Z0701B under carpet and hard-floor load cycles. The BMS held charge cutoff at 25.2V fully charged and tripped low-voltage protection at 18V under sustained motor draw — consistent with factory spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for this vacuum:\u003c\/strong\u003e\n    Do not leave the Z0701B sitting on the charging dock permanently. Continuous dock charging causes trickle-charge stress on Li-ion cells and accelerates capacity fade. Charge fully, then remove the vacuum from the dock until the next use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than rated — usually because a partially blocked filter or clogged brush roll forces the motor to work harder. That elevated draw causes voltage to sag at the pack terminals, dropping effective motor power well before the cell is actually depleted. The BMS reads the sag as a low-state signal and throttles output. Clear the filter and brush roll first, then retest — if suction holds at full power for a normal cycle, the pack is fine and the blockage was the cause.\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 failed battery. When suction is restricted — blocked filter, jammed brush roll, or a sealed floor surface cutting off airflow — current draw spikes above the BMS trip threshold, and the pack shuts output to protect the cells. After a few seconds the BMS resets, power returns, and the cycle repeats. Fix the restriction first: remove the filter and tap it clean, check the brush roll for wrapped debris, and confirm the intake path is clear. If the cutout stops after clearing the restriction, the pack and BMS are functioning correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427950919770,"sku":"BWCS-ERK158VX-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427950952538,"sku":"BWCS-ERK158VX-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427950985306,"sku":"BWCS-ERK158VX-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERK158VX-1.webp?v=1779933419","url":"https:\/\/batteryweb.com\/products\/eureka-powerplush-z0701b-replacement-battery-216v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
