It fits the OT-9001X and OT-9001A variants using the same connector and cell format. Dimensions are 73.10 × 54.13 × 4.40mm — confirm these against your existing cell before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixi 4 6.0 series fit:\u003c\/strong\u003e\n    The OT-9001X, OT-9001A, and LTE variant all run the same 3.8V voltage rail with the same flex-tab connector and identical BMS handshake requirements. One cell revision covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the OT-9001 platform. The BMS accepted charge current without fault flags, and protection circuits triggered correctly at both high-current draw and low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated coulomb counter.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Pixi 4 6.0\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pixi 4 6.0 pulls a hard surge when the 6-inch display and LTE modem run simultaneously. An aged or partially degraded cell hits its internal resistance ceiling before the fuel gauge reads zero — voltage drops below the BMS cutoff threshold while the OS still shows charge remaining. This is a voltage cliff, not a firmware bug. A fresh cell with lower internal resistance sustains the load and eliminates the early-shutdown event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Pixi 4 6.0 stores a learned discharge curve from the original cell. After a replacement, that stored curve no longer matches the new cell's actual voltage-to-capacity profile. The result is percentage readings that jump, stall, or cut out early. One full uninterrupted discharge to auto-shutdown followed by a complete charge to 100% forces the coulomb counter to re-learn against the new cell — after that cycle, readings stabilise.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392076513370,"sku":"BWCS-OT805SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392076546138,"sku":"BWCS-OT805SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392076578906,"sku":"BWCS-OT805SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT805SL-1.webp?v=1779143639","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pixi-4-60-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
