It fits a broad range of Chromebook 14 variants, including the 14-Q063CL, 14-Q010SA, and 87 additional sub-models sharing the same battery bay and connector. OEM part numbers covered include A2304XL, 738392-005, HSTNN-LB5R, and TPN-Q134.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChromebook 14 and 14Q platform fit:\u003c\/strong\u003e\n    These models share a common 7.5V battery rail, connector pinout, and BMS handshake protocol across the full Chromebook 14 family. One cell fits the entire lineup 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 Chromebook 14 unit. The BMS communicated correctly with the system, charge termination triggered at full capacity, and no fault codes appeared during the session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eChrome OS battery learn cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run the Chromebook down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning Chrome OS displays after any cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Chrome OS shows 0% or \"unknown battery\" after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the Chromebook 14 stores calibration data tied to the original cell's charge history. When a new cell goes in, the IC has no valid reference points and reports either 0% or an unknown state. This is not a fault with the replacement cell. Running one full discharge-to-hibernate cycle followed by a complete uninterrupted charge gives the fuel gauge IC enough data to recalibrate against the new cell's actual capacity. After two to three cycles, the percentage readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eChromebook 14 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load, even though the fuel gauge still shows charge remaining. The fuel gauge is reading stored calibration data from the old, degraded cell — the new cell's voltage curve doesn't match that map yet. The fix is a full discharge-to-hibernate cycle: let Chrome OS shut the system down naturally, then charge to 100% without interruption. After that cycle, the BMS and fuel gauge align on the new cell's voltage floor, and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409771462746,"sku":"BWCS-HPN134NB-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409771495514,"sku":"BWCS-HPN134NB-2","price":127.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409771528282,"sku":"BWCS-HPN134NB-3","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPN134NB-1.webp?v=1779580789","url":"https:\/\/batteryweb.com\/products\/hp-chromebook-14-replacement-battery-75v-6750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
