It replaces OEM part number 140127175457. When the original cell degrades and suction weakens well before the indicator reaches low, this cell restores the vacuum to its rated draw capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZB3101 and ZB3102 platform fit:\u003c\/strong\u003e\n    These models share the same 10.8V battery rail, connector housing, and BMS handshake protocol, which is why a single cell covers the full range. Voltage tolerance across this platform sits within ±0.5V on a fresh charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a ZB3101 unit. The BMS negotiated correctly, the charger accepted the pack without fault codes, and the motor drew current at the rated 10.8V rail throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on Electrolux stick vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. These vacuums on continuous dock charge develop capacity fade significantly faster than those charged only when depleted. 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 motor on this platform draws harder when airflow is restricted — a partially blocked filter forces the motor to pull more current than the cell can sustain at rated voltage. The BMS responds by allowing voltage to sag, which the vacuum reads as low power before the indicator catches up. This is the most common reason suction feels weak with a battery that still shows charge. Clean or replace the filter first, then test the battery separately at 10.8V under no-load with a multimeter.\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 the vacuum hits a carpet edge or debris blockage, the motor spikes current draw sharply. If the cell is aged or the filter is restricted, that spike exceeds the BMS protection threshold and the pack shuts off momentarily to protect the cell. The recovery pause is the BMS resetting after the current normalises. Check the filter condition first — a clean filter lowers motor draw and stops most of these trips.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428009115738,"sku":"BWCS-ACX700VX-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428009148506,"sku":"BWCS-ACX700VX-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428009181274,"sku":"BWCS-ACX700VX-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACX700VX-1.webp?v=1779933823","url":"https:\/\/batteryweb.com\/products\/electrolux-900273758-replacement-battery-108v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
