It replaces OEM part numbers VGP-BPS35 and VGP-BPS35A. Fits a broad range of SVF-prefix VAIO models including the SVF14215SC and SVF1421E2E.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFIT 14E and FIT 15E platform fit:\u003c\/strong\u003e\n    Both the 14-inch and 15-inch FIT series share the same battery bay geometry, connector pinout, and BMS handshake protocol — that is why one cell covers both screen sizes 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 VAIO FIT platform. The BMS communicated correctly with the BIOS, charge acceptance was normal, and no protection cutoff trips occurred under mixed CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate-level cutoff, then charge it uninterrupted to 100%. This forces the BIOS to run its battery learn cycle against the new cell and clears the inaccurate health warning that appears after every cell swap on VAIO hardware.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VAIO FIT BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VAIO firmware stores charge history and wear data in EEPROM on the battery itself. When a new cell arrives, that EEPROM is blank or carries factory default values the BIOS does not recognise as a healthy profile. The system reads this as degraded rather than new. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% writes a fresh learn-cycle baseline. After that cycle, the health indicator updates correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the VAIO FIT\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge reports 20–30% remaining, but the cell hits its low-voltage cutoff under full CPU and display load before the estimate catches up. It is a calibration lag, not a faulty battery. Complete two full discharge-to-hibernate and full-recharge cycles — the fuel gauge re-maps the curve and the shutdowns stop. After calibration, verify the system reads above 14.4V at full charge in BIOS hardware monitor.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410738610266,"sku":"BWCS-BPS35NB-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410738643034,"sku":"BWCS-BPS35NB-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410738675802,"sku":"BWCS-BPS35NB-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS35NB-1.webp?v=1779580872","url":"https:\/\/batteryweb.com\/products\/sony-vaio-fit-14e-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
