It fits the 10-P043TU along with the 10-P000NA, 10-P000ND, 10-P000NF, and 167+ additional x2 10 variants. The connector, BMS handshake, and physical form factor match OEM spec across the full P-series lineup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ex2 10 P-series compatibility:\u003c\/strong\u003e\n    Every model in this lineup runs the same 7.7V two-cell Li-Polymer configuration with a shared BMS communication protocol. HP standardised the SW02XL form factor across the P-series so one cell covers the full range — the HSTNN-IB7N and HSTNN-LB7N designations refer to the same physical pack with different regional part codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a 10-P series unit and confirmed the BMS completed handshake without fault codes. Charge acceptance ran clean from 0% to 100% with no mid-cycle cutoff. The EEPROM read-back matched expected Wh values after two full calibration cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration — x2 10 hybrid:\u003c\/strong\u003e\n    After fitting this cell, run the tablet side down to hibernate-cutoff under normal load — screen on, a few browser tabs open. Then charge uninterrupted to 100% without disconnecting. This forces the fuel gauge IC to re-baseline against the new cell and clears the inaccurate health warning the BIOS throws after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP x2 10 BIOS stores learned battery data in EEPROM tied to the original cell. When a new cell goes in, that stored data no longer matches the actual chemistry, so the BIOS flags the pack as degraded or unknown — even on a brand-new replacement. This is a firmware calibration issue, not a cell fault. Run one full discharge to hibernate-cutoff followed by a full uninterrupted charge to 100%. After two cycles, the fuel gauge IC re-learns the cell's actual capacity curve and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTablet shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated to the new cell's voltage curve. The x2 10 runs a combined CPU-plus-display load during active use that pulls enough current to expose a steep voltage cliff in an uncalibrated cell — the BMS interprets that voltage drop as empty and triggers a shutdown even though capacity remains. The fix is the same calibration cycle: discharge fully to hibernate, charge straight to 100% without interruption, and repeat once more. After two cycles, the OS reading will track actual cell state down to around 3.0V per cell before cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409520722010,"sku":"BWCS-HNX210NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409520754778,"sku":"BWCS-HNX210NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409520787546,"sku":"BWCS-HNX210NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HNX210NB-1.webp?v=1779579905","url":"https:\/\/batteryweb.com\/products\/hp-nnotebook-x2-10-p043tu-replacement-battery-77v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
