It fits a wide range of sub-models including the 14-N048CA and 14 B109WM. OEM part numbers covered include LA04, OA03, OA04, HSTNN-UB5M, HSTNN-UB5N, TPN-Q129 through TPN-Q132, and several hundred additional HP cross-references.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTouchsmart 14 and 15 series compatibility:\u003c\/strong\u003e\n    Both lines share the same 14.8V four-cell architecture, LA04\/OA04 connector standard, and BMS handshake protocol — one cell fits both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Pavilion Touchsmart 14 chassis. The BMS negotiated correctly, charge acceptance reached full capacity, and the protection circuit responded to overcurrent and over-temperature thresholds as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on Touchsmart models:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on-screen 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 after swapping the Touchsmart cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pavilion BIOS reads health data from the battery's EEPROM on first contact. When a new cell arrives, the EEPROM counters are at zero and don't match the aged-profile the BIOS expects — so it flags the battery as unknown or degraded. This is a data mismatch, not a fault with the cell. Running one complete discharge-to-hibernate followed by an uninterrupted full charge gives the BIOS fuel gauge IC enough data to recalibrate. After two or three cycles the health indicator typically returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTouchsmart shuts down unexpectedly at 20–30% charge shown\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 — the fuel gauge still reads 20–30% but the actual cell voltage has already hit the floor. It's a voltage-cliff problem common to Li-ion cells that have partially degraded, or to a new cell whose gauge IC hasn't calibrated yet. On a freshly installed cell, run the full discharge-and-recharge calibration cycle described above. If the shutdowns persist after three cycles, check that the BIOS is not limiting discharge — enter BIOS setup and confirm no battery protection floor is set above 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410736414810,"sku":"BWCS-HPG350NB-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410736447578,"sku":"BWCS-HPG350NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410736480346,"sku":"BWCS-HPG350NB-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPG350NB-1.webp?v=1779580715","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-touchsmart-14-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
