It fits the Split 13, Split 13-M010DX, Split 13 x2, and Pavilion 13-P100ER among over 100 compatible models. The OEM part number is WO03XL, also cross-referenced as HSTNN-IB5I and 725606-001.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSplit 13 x2 hybrid platform:\u003c\/strong\u003e\n    These models share a single battery rail tied to both the tablet and keyboard dock sections. The 11.1V three-cell configuration matches the voltage requirement across that shared BMS handshake — swapping a mismatched cell trips the dock connector protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and load cycle on the Split 13 platform. The BMS negotiated correctly, charge acceptance was clean to 100%, and no protection faults triggered during the discharge sweep.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Split 13:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to hibernate cutoff under normal use, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Split 13 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Split 13 stores charge history and health data in EEPROM on the original cell's BMS board. When a new cell goes in, that EEPROM data is blank or mismatched, so the BIOS reads it as a degraded or unknown battery. This is a firmware interpretation issue, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough data to recalibrate. After two to three full cycles, the health indicator typically returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSplit 13 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom appears when the fuel gauge IC hasn't yet mapped the new cell's voltage curve. The gauge is still using the old cell's discharge profile, so it predicts a safe cutoff well before the actual voltage cliff. The laptop shuts down because the system hits its low-voltage threshold while the displayed percentage still looks safe. Run two to three full discharge and charge cycles — the fuel gauge IC recalibrates against the new cell and the shutdowns stop. After calibration, set the display brightness to mid-range and recheck the gauge reads correctly at the 15% mark.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409771724890,"sku":"BWCS-HPX132NB-1","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409771757658,"sku":"BWCS-HPX132NB-2","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409771790426,"sku":"BWCS-HPX132NB-3","price":76.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX132NB-1.webp?v=1779580789","url":"https:\/\/batteryweb.com\/products\/hp-split-13-replacement-battery-111v-2950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
