It fits OT-7043, OT-7043A, and OT-7043Y variants along with four additional model numbers in the OT-7043 line. Replace this battery when the original no longer holds a charge, shuts down unexpectedly, or fails to power the device at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-7043 series compatibility:\u003c\/strong\u003e\n    Every OT-7043 variant shares the same 3.8V power rail, battery bay dimensions, and connector pinout. The BMS handshake protocol is consistent across the line, so one cell covers the full 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 charge and discharge cycles on the OT-7043 platform. The BMS accepted the cell cleanly, charge termination triggered correctly at 4.35V, and protection cutoffs for overcurrent and over-temperature fired within spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use, disable fast charging and run one complete discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one full reference cycle against the new cell's discharge curve before fast-charge current is applied 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\"\u003eWhy the POP 2 5.0 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-7043 uses a coulomb-counting fuel gauge IC that builds its percentage model against the original cell's charge and discharge history. When a new cell goes in, that learned curve no longer matches the actual capacity. The gauge reports stale data until it completes at least one full reference cycle. Run the phone from 100% down to auto-shutdown, then charge straight to full without interruption — one cycle is usually enough for the gauge to re-anchor its model to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem or display draws a high-current burst and the cell voltage drops faster than the fuel gauge predicted — the BMS sees the voltage cliff and cuts power before the percentage display catches up. It is common on the first few cycles of a new cell before the gauge recalibrates. The BMS protection threshold on this cell sits at approximately 3.0V per cell under load. After two to three full discharge-charge cycles the gauge tracks the new cell's voltage curve more accurately and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404145393754,"sku":"BWCS-VF895SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404145426522,"sku":"BWCS-VF895SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404145459290,"sku":"BWCS-VF895SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VF895SL-1.webp?v=1779369095","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-2-50-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
