It matches the OEM footprint at 54.13 × 40.57 × 10.84mm and uses part numbers LIBR160 and 35H00082-00M. Capacity figure is taken directly from product data — 8.33Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX02HT fitment:\u003c\/strong\u003e\n    The X02HT uses a single-cell 3.7V nominal pack with a proprietary connector pinout that carries thermistor data back to the charge IC. This replacement matches that pinout, so the phone's charge controller sees a valid cell and does not block charging.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the X02HT platform. The BMS accepted the charge handshake without triggering a fault, and the fuel gauge IC began tracking state-of-charge from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, run one complete discharge down to auto-shutoff and then charge uninterrupted to 100% before normal use. The X02HT fuel gauge IC carries its calibration curve from the old cell — one full cycle resets the coulomb counter baseline 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-h3\"\u003eSudden shutdown at 20–30% on the X02HT after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X02HT's charge IC was calibrated to the discharge curve of the original, degraded cell. A fresh cell has a steeper voltage drop near the end of discharge, and when the modem radio or display draws a short high-current burst, cell voltage dips below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. This is a voltage cliff, not a capacity problem. One full discharge-to-shutoff cycle followed by a full charge lets the fuel gauge IC re-map the new cell's curve and eliminates the premature cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery door during the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new high-impedance cell presents more internal resistance on the first charge than a broken-in cell does. The X02HT charge IC responds by pushing a constant current into that resistance, which generates more heat than normal until the cell conditions through one cycle. If the phone feels warm but not hot and charging completes normally, this is expected. If the phone stays warm after the first full cycle, check that the battery door is seated flush — any gap reduces thermal transfer to the chassis and traps heat near the cell. Surface temperature should drop to ambient within five minutes of charge completion.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405157072986,"sku":"BWCS-DC730XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405157105754,"sku":"BWCS-DC730XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405157138522,"sku":"BWCS-DC730XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DC730XL-1.webp?v=1779370315","url":"https:\/\/batteryweb.com\/products\/softbank-x02ht-replacement-battery-37v-2250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
