It replaces OEM part numbers TLp030B2, TLp030B1, C3000003C1, and TLP030J1. Swap it in when the original cell no longer holds a usable charge through a standard day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePop S7 and OT-7045 series fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 3.8V nominal rail, and connector pinout. The BMS handshake protocol across TLp030B1 and TLp030B2 variants is identical, so the phone's charge IC accepts this cell without firmware conflict.\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-7045 platform. The BMS engaged protection cutoff correctly at both ends of the voltage window, and the charge IC accepted the cell without fault flags on the first cycle.\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 and run one complete discharge-charge cycle at standard current. This lets the phone's fuel gauge IC map the new cell's discharge curve before high-current charging pushes into an uncalibrated state.\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 S7 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pop S7's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches actual cell voltage under load. The modem radio and display draw brief high-current spikes that pull cell voltage below the BMS cutoff threshold — even when the OS still shows 20–30% remaining. The phone cuts out not because the cell is empty, but because the gauge IC is reading from stale calibration data. One full discharge-charge cycle at standard current resets the coulomb counter and eliminates most of these early shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell starts with slightly higher internal impedance than a cell that has been cycled. The charge IC on the OT-7045 platform responds by delivering current at the same rate it used with the old cell, which generates more heat across a higher-resistance cell. This is normal for the first two to three cycles and not a fault condition. If the phone stays warm beyond the third full charge, check that the rear cover is seated correctly — trapped heat from a loose cover is a separate issue that can trigger thermal throttling in the charge IC.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404214698074,"sku":"BWCS-OT985SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404214730842,"sku":"BWCS-OT985SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404214763610,"sku":"BWCS-OT985SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT985SL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-s7-replacement-battery-38v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
