It fits the Alcatel 7, 7 LTE, OT-6062W, and OT-6062 smartphones. Swap it in when the original cell can no longer hold a charge through a normal day of use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-6062 platform compatibility:\u003c\/strong\u003e\n    The 7, 7 LTE, OT-6062W, and OT-6062 share the same battery bay dimensions and connector pinout. All four models accept the TLP038C1 footprint — 87.80 × 60.40 × 4.12mm — and draw from the same 3.85V nominal voltage rail. No adapter or modification needed.\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-6062 platform. The BMS accepted the cell cleanly, reported charging current correctly, and triggered the charge-complete cutoff at the expected full-cell voltage without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutdown, then charge uninterrupted to 100% before enabling fast charging. The Alcatel 7's fuel gauge IC uses a coulomb counter calibrated to the old cell's discharge curve — one full cycle resets it against the new cell's actual capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-p\"\u003eSudden shutdown at 20–30% on the Alcatel 7 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a steeper voltage cliff in the lower charge range than a worn cell. The Alcatel 7's power management IC is still reading cutoff thresholds mapped to the old, degraded cell. When the modem fires a burst transmission or the screen peaks in brightness, the voltage dips below the IC's hard cutoff before the fuel gauge reaches 0%. One complete calibration cycle — full drain to auto-shutdown, then uninterrupted charge to 100% — realigns the IC's cutoff map to the new cell's discharge curve and eliminates the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-p\"\u003eDevice won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge in storage. If the TLP038C1 arrived or sat installed below roughly 2.5V, the BMS enters lockout to prevent cell damage. The phone will show no response to the power button. Connect a charger and leave it for 15–20 minutes without pressing anything — the charge IC needs to push a small trickle current to bring the cell above the BMS re-enable threshold before the device will attempt to boot. If the charging indicator appears, the cell is recovering; allow it to reach at least 3.0V before powering on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391994888282,"sku":"BWCS-TMR606SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391994921050,"sku":"BWCS-TMR606SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391994953818,"sku":"BWCS-TMR606SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMR606SL-1.webp?v=1779142786","url":"https:\/\/batteryweb.com\/products\/alcatel-7-replacement-battery-385v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
