It fits OT-6040A, OT-6040E, and more than 22 additional Alcatel Idol X variants sharing the same connector and BMS handshake. Cross-references include TLp020C1, TLp020C2, and CAC2000012C2.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdol X family compatibility:\u003c\/strong\u003e\n    The OT-6040A and OT-6040E share the same 3.8V voltage rail, physical footprint (73.75 × 55.46 × 3.52mm), and BMS communication protocol — which is why one cell covers the full Idol X range without modification.\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 an OT-6040 unit. The BMS accepted the cell on first insertion, protection circuits triggered correctly at low-voltage threshold, and the charge IC handed off cleanly at 4.35V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The fuel gauge IC on the Idol X is calibrated to the original cell's discharge curve — letting it run one full unassisted cycle prevents it from applying the wrong current profile to an uncalibrated cell.\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 Idol X after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Idol X fuel gauge IC tracks charge using a coulomb counter mapped to the original cell's internal resistance curve. A new cell has lower impedance, so the voltage-to-capacity curve shifts — the OS reads 25% while the actual cell voltage is already at the modem's cutoff floor. Under the load spike of a 4G transmission or screen-on burst, the cell voltage drops below 3.4V for a fraction of a second, and the device shuts down before the OS can catch it. One full slow-charge cycle lets the coulomb counter re-anchor to the new cell's actual discharge profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after sitting in storage with a flat battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the original cell discharged below 2.5V during storage, the BMS enters a lockout state to prevent a damaged cell from accepting charge. Swapping in this replacement cell clears that lockout immediately — the new cell ships with a partial charge above the BMS re-initialisation threshold. If the phone still won't respond after fitting the new cell, hold the power button for 12 seconds to force a hard reset, then connect a charger and confirm the charge LED activates within 30 seconds.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404273909850,"sku":"BWCS-OT604XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404273942618,"sku":"BWCS-OT604XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404273975386,"sku":"BWCS-OT604XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT604XL-1.webp?v=1779369616","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-idol-x-replacement-battery-38v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
