It matches OEM part number BT-000484A and slots directly into both ET6X and ET6XW units. Capacity is sourced from the product specification — 66.88Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eET6X and ET6XW compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — a single cell revision covers the full ET6X platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on an ET6XW unit. The BMS communicated correctly with the tablet's charge IC, accepted a full charge without fault codes, and held stable voltage across display-on and WiFi-active load states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap fuel gauge reset:\u003c\/strong\u003e\n    After installing this battery, run one complete discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage readings that commonly appear after a battery swap on ET6X units.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eET6X shutting down at 15–25% battery remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to an old, degraded cell. The new cell holds a higher actual charge at any given reported percentage, but the voltage curve the tablet references is wrong. Under combined display and WiFi load, voltage drops faster than the tablet expects at that percentage, triggering a low-voltage protection shutoff. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — this re-maps the voltage curve to the new cell and stops the early cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFast charging not available after battery replacement on ET6X\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ET6X charge IC uses a negotiation handshake before engaging fast charge mode. On a brand-new cell, this handshake sometimes does not complete on the first cycle — the tablet defaults to standard charge as a safety fallback. Allow the first charge cycle to complete fully at standard rate without interrupting it. On the second charge, fast charge typically re-engages once the charge IC has logged one accepted full cycle against the new cell's parameters.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425820967002,"sku":"BWCS-ZRT600SL-1","price":145.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425820999770,"sku":"BWCS-ZRT600SL-2","price":173.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425821032538,"sku":"BWCS-ZRT600SL-3","price":194.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZRT600SL-1.webp?v=1779929854","url":"https:\/\/batteryweb.com\/products\/zebra-et6x-replacement-battery-76v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
