It matches OEM part numbers TLp031C2 and TLP031C1. Physical dimensions are 84.21 × 56.74 × 4.17mm — measure your original before installing if you are unsure of your exact variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOT-8030 series compatibility:\u003c\/strong\u003e\n    The OT-8030, OT-8030Y, and OT-8030B share the same battery bay dimensions, connector pinout, and BMS handshake protocol. All variants draw from the same 3.8V nominal voltage rail, so one cell covers the entire OT-8030 line 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 full charge-discharge cycles on an OT-8030 unit. The BMS accepted charge from the native charge IC without tripping overcurrent protection, and the fuel gauge IC reported state-of-charge consistently once the coulomb counter completed its first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against 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\"\u003eWhy the One Touch Hero 2 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe OT-8030 uses a coulomb-counting fuel gauge IC that builds its state-of-charge model from the previous cell's charge and discharge history. When you install a new cell, that stored model no longer matches the actual cell chemistry and impedance. The gauge will read anywhere from 5 to 20 percentage points off until it relearns the curve. One full discharge to 3.0V followed by a complete charge cycle resets the model and restores accurate readings.\u003c\/p\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 problem. Under modem transmission or screen-on load, current draw spikes sharply and cell voltage drops below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. A fresh Li-Polymer cell at higher impedance than a warm, cycled cell is most vulnerable in the first ten cycles. After the cell beds in and the fuel gauge recalibrates, the cutoff point typically drops back below 10%. If shutdowns persist past cycle 15, check that the battery connector is fully seated — a partial connection raises contact resistance and accelerates the voltage drop under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404204114010,"sku":"BWCS-OT803SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404204146778,"sku":"BWCS-OT803SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404204179546,"sku":"BWCS-OT803SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OT803SL-1.webp?v=1779369370","url":"https:\/\/batteryweb.com\/products\/alcatel-one-touch-hero-2-replacement-battery-38v-3100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
