It fits the X03HT directly and matches the OEM voltage rail and connector. Capacity is rated at 8.33Wh — figures are taken from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX03HT platform fit:\u003c\/strong\u003e\n    The X03HT uses a single-cell 3.7V Li-ion pack with a specific connector pinout and BMS handshake. This cell matches that voltage rail and connector geometry — 54.03 × 39.60 × 11.37mm — so it seats without modification.\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 X03HT platform. The BMS accepted the cell without fault flags, and the charge IC reached full termination voltage without interruption.\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-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging begins on an uncalibrated cell.\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 X03HT after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X03HT's fuel gauge IC was calibrated to the original cell's discharge curve. A new cell with a different internal resistance profile causes the reported state-of-charge to diverge from actual voltage. Under modem or screen load, the cell voltage drops faster than the gauge predicts, and the phone shuts off before the display reaches 0%. One full discharge-charge cycle — taken slowly, without fast charge enabled — resets the coulomb counter and tightens percentage accuracy.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eX03HT won't power on after sitting in storage with a flat battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the cell discharged below roughly 2.5V during storage, the BMS enters a protection lockout to prevent cell damage. The phone will show no response on the charger for several minutes — this is normal. Connect to a wall charger, not a PC USB port, and leave it for 15–20 minutes without pressing the power button. Once the BMS registers safe voltage, the charge IC takes over and the boot sequence starts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405183090778,"sku":"BWCS-DS710XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405183123546,"sku":"BWCS-DS710XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405183156314,"sku":"BWCS-DS710XL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DS710XL-1.webp?v=1779370332","url":"https:\/\/batteryweb.com\/products\/softbank-x03ht-replacement-battery-37v-2250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
