It fits the Holiday, Omega, and G20 lines alongside six additional models that share the same battery footprint and connector. Swap it when the original cell no longer holds a usable charge through a normal day.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX710e, Holiday, Omega, G20 platform fit:\u003c\/strong\u003e\n    These models share the same 54.90 × 47.92 × 5.20mm cell housing, identical 3.7V rail, and the same BH39100 connector pinout — the charge IC and BMS handshake protocol are consistent across the entire variant family, so one cell covers all of them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an X710e and monitored BMS communication through charge and discharge. The protection circuit responded correctly to cutoff at the top and bottom voltage thresholds, and the charge IC accepted the cell without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge-to-charge cycle at standard rate. The fuel gauge IC on the X710e calibrates its coulomb counter against the actual discharge curve of the new cell — skipping this step causes the percentage readout to drift or jump erratically for the first several cycles.\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 X710e after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe X710e's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. Under high-draw moments — screen at full brightness, mobile data active, GPS running — the cell voltage drops faster than the gauge predicts. The phone interprets this as a genuine low-voltage cutoff condition and shuts down even though the percentage display still reads 20–30%. One full discharge cycle at standard charge rate lets the coulomb counter rebuild its model against the new cell. After that cycle, shutdowns below 15% become rare.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone gets warm near the battery compartment during first-cycle charging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell arrives from storage with higher internal impedance than a well-cycled cell. During the first charge, the charge IC on the X710e pushes current into that higher-impedance cell, and the extra resistance converts more energy to heat than usual. This is normal and settles after one or two full cycles as the cell's impedance drops toward its operating baseline. If the back panel stays warm beyond the second full charge — or if the phone becomes hot rather than warm — check that no case or surface is trapping heat around the battery compartment. Charging on a flat, ventilated surface for the first two cycles keeps temperatures within safe range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405057884250,"sku":"BWCS-HTX710SL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405057917018,"sku":"BWCS-HTX710SL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405057949786,"sku":"BWCS-HTX710SL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTX710SL-1.webp?v=1779369882","url":"https:\/\/batteryweb.com\/products\/htc-x710e-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
