It fits the tablet base unit — the component that operates independently once separated from the keyboard dock. Compatible models include the Split x2 13-R010dx 13.3, Pavilion 13-R030CA X2 Detachable PC, TPN-C118, and TPN-C119.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSplit x2 tablet base fit:\u003c\/strong\u003e\n    These models share the same detachable tablet chassis, voltage rail, and thin-profile Li-Polymer connector. The BMS handshake is identical across the TPN-C118 and TPN-C119 variants, so the same cell works across all listed units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Split x2 unit. The BMS accepted the new cell without fault codes, charge termination triggered correctly at capacity, and voltage stayed stable under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on the Split x2:\u003c\/strong\u003e\n    After fitting, run the tablet on battery until it hits hibernate cutoff — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a 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 x2 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Split x2 stores battery health data in EEPROM tied to the original cell. When a new cell is installed, the BIOS reads zero charge history and flags the battery as degraded — even though the cell is new. This is a firmware reporting issue, not a hardware fault. Running one full discharge-to-hibernate then a complete uninterrupted charge gives the BIOS enough cycle data to recalibrate. After one or two cycles the health status updates to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSplit x2 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 hasn't calibrated against the new cell yet. The percentage shown is based on voltage curves stored for the old cell, so the displayed figure doesn't match actual remaining capacity. Under full CPU and display load, the new cell hits a voltage cliff the old calibration data doesn't account for, and the system shuts down as a protection response. Run two full discharge-to-hibernate cycles with uninterrupted charges to completion — after that the fuel gauge IC re-maps against the new cell and the cutoff behaviour resolves. Confirm the cell is reading above 8.2V at full charge before trusting the percentage gauge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409772052570,"sku":"BWCS-HPC118NB-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409772085338,"sku":"BWCS-HPC118NB-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409772118106,"sku":"BWCS-HPC118NB-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPC118NB-1.webp?v=1779580789","url":"https:\/\/batteryweb.com\/products\/hp-split-x2-13-r010dx-133-replacement-battery-74v-4050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
