It replaces OEM part numbers TLi020F1, TLi020G1, TLi020F2, TLi020FA, TLi019B1, TLi019B2, and TLi018B2. Fit it when the original cell no longer holds voltage under screen or modem load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-7040 series cross-compatibility:\u003c\/strong\u003e\n    The OT-7040, OT-7040D, and Pop C7 share the same battery bay dimensions, contact layout, and charge IC handshake. One cell covers all of them because the BMS talks to the same charge controller across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the OT-7040 charge IC and confirmed BMS communication, charge acceptance at the correct 4.35V cutoff, and stable voltage delivery under simultaneous LTE and screen-on load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\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 fuel gauge IC map the new cell's discharge curve before fast-charge current is pushed into an uncalibrated coulomb counter.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity fault. The Pop C7's fuel gauge IC still holds the old cell's discharge curve in memory, so it reads 25% when the new cell's actual resting voltage is already near the BMS low-voltage cutoff. Under modem or display load, current draw spikes and the cell voltage drops below 3.4V instantly — the BMS trips and the phone cuts out. Run one full discharge to automatic shutdown, then charge uninterrupted to 100% to force the IC to relearn the curve against the new cell. After that cycle, the percentage readout and shutoff behaviour will track correctly.\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 cell comes with slightly higher internal impedance than a broken-in original. During early charge cycles, the charge IC pushes current into that higher resistance, and some energy dissipates as heat at the cell surface. This is normal for the first three to five cycles and reduces as the cell's impedance settles. If the phone is hot to the touch — not just warm — or if charging stops before 100%, check that the charge cable is delivering clean 5V and that the port contacts are clean. Surface warmth alone during the first cycle is not a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404274860122,"sku":"BWCS-OT704SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404274892890,"sku":"BWCS-OT704SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404274925658,"sku":"BWCS-OT704SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT704SL-1.webp?v=1779369616","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-pop-c7-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
