It fits the VAIO FH14, VAIO FH 14 Ultra, VJFH41C0101B, VJFH41C0101N, and over 45 additional VAIO FH-series variants. Voltage and connector match the original cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVAIO FH series compatibility:\u003c\/strong\u003e\n    All listed FH-series models run the same 15.2V battery rail, use the same physical connector, and share BMS handshake protocols — which is why a single cell covers this many variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a VAIO FH-series unit. The BMS accepted the handshake on first insertion, charge current ramped normally, and the cell held voltage through discharge without early cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for VAIO FH14:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to hibernate-cutoff on battery only — no AC during discharge — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears 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 replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VAIO BIOS reads health data from EEPROM embedded in the battery pack. When a new cell arrives, its EEPROM values haven't been aligned to your system's charge history, so the BIOS flags it as degraded even though the cell is new. This is not a fault with the replacement cell — it's a data mismatch. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%, and the BIOS recalculates health against the new cell's actual characteristics.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell's voltage drops sharply under combined CPU and display load — a voltage cliff where the fuel gauge IC still reads 20–30% but the cell can no longer sustain the draw. On the VAIO FH14, full-brightness display plus active processor pulls enough current to trigger this cliff faster than the gauge updates. The fuel gauge IC needs two to three full calibration cycles against the new cell before its readings stabilise. After three full discharge-to-hibernate and full-charge cycles, the gauge tracks the actual cell voltage curve and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409538547802,"sku":"BWCS-CLN400NB-1","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409538580570,"sku":"BWCS-CLN400NB-2","price":107.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409538613338,"sku":"BWCS-CLN400NB-3","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLN400NB-1.webp?v=1779579965","url":"https:\/\/batteryweb.com\/products\/sony-vaio-fh14-replacement-battery-152v-3050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
