It fits the OT-4030, OT-4030D, OT-4030X, and One Touch S Pop. It replaces OEM part numbers CAB60B0000C2, CAB60B0001C2, and TLiB50B.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-4030 series compatibility:\u003c\/strong\u003e\n    The OT-4030, OT-4030D, OT-4030X, and One Touch S Pop all share the same physical battery bay, connector pinout, and BMS handshake protocol — which is why one cell covers all four variants without any 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 the OT-4030 platform. The BMS communicated correctly with the charge IC, accepted current without cutoff errors, and held voltage steady across screen-on and modem-active load conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable any fast-charge adapter and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one complete reference cycle against the new cell's discharge curve before it begins reporting accurate percentages.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the OT-4030 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-4030 uses a fuel gauge IC that builds its percentage model from the discharge curve of the cell it learned on — typically the original factory cell. When a new cell goes in, the stored curve no longer matches the actual cell chemistry and capacity. The gauge reports percentages based on outdated reference data, so the number on screen can be off by 10–20%. One full uninterrupted discharge-to-shutdown followed by a full charge resets the coulomb counter and forces the IC to re-learn the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet recalibrated and the cell voltage drops below the modem's minimum operating voltage while the screen still shows 20–30% remaining. The modem draws a short high-current burst during a call or data event, the cell voltage sags, and the phone shuts off to protect the hardware. The percentage shown at shutdown is meaningless until recalibration is complete. Run the full discharge-recharge cycle described above — after that cycle, the gauge will cut off closer to the real 3.2–3.3V floor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404209291354,"sku":"BWCS-OT403XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404209324122,"sku":"BWCS-OT403XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404209356890,"sku":"BWCS-OT403XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT403XL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/alcatel-ot-4030-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
