It replaces OEM part numbers TLi018D1 and TLi018D2. Fit models include the OT-5038, OT-5038A, and OT-5038E, among others sharing the same battery bay and connector spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-5038 series compatibility:\u003c\/strong\u003e\n    The OT-5038, OT-5038A, and OT-5038E all run on the same 3.7V single-cell rail with an identical connector pinout and BMS handshake protocol. One cell covers the entire sub-family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the OT-5038 platform. The BMS accepted the cell without fault flags, and the charge IC brought it to 4.2V termination cleanly on the first cycle.\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 installation. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins against an uncalibrated baseline.\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 Pop D5 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff problem, not a capacity problem. The fuel gauge IC still references the old cell's discharge curve, so it reads 25% when the new cell's actual terminal voltage has already dropped below the modem's minimum operating threshold. Under screen-on or active call load, the voltage dips sharply and the phone cuts out before the OS can log a low-battery event. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and eliminates most cliff shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the OT-5038 was calibrated to the original cell's internal resistance and voltage curve. A new cell has different impedance characteristics, so the gauge's state-of-charge estimate drifts — often reading high early in discharge and then dropping steeply. The fix is one full manual cycle: drain the phone until it shuts off automatically, then charge uninterrupted to 100% with the screen off. After that cycle, percentage reporting stabilises to within a few points of actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392090636378,"sku":"BWCS-OT503SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392090669146,"sku":"BWCS-OT503SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392090701914,"sku":"BWCS-OT503SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT503SL-1.webp?v=1778773879","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-d5-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
