It replaces OEM part numbers VGP-BPS30 and VGP-BPS30A. The battery fits the slim bay of these 11- and 13-inch ultrabooks and connects using the original multi-pin BMS interface.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSVT-11 and SVT-13 platform fit:\u003c\/strong\u003e\n    Both the SVT-11 and SVT-13 lines run the same 11.1V battery rail and share the VGP-BPS30 connector pinout. The BMS handshake protocol is identical across these two chassis, so one cell serves both without any firmware conflict.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an SVT-13 unit and confirmed the BMS passed charge authority to the motherboard within two minutes of connection. The protection circuit tripped correctly at low-voltage cutoff and recovered cleanly on reconnect.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on VAIO ultrabooks:\u003c\/strong\u003e\n    After fitting, run the laptop on battery only until it hibernates at low charge — do not interrupt. Then charge uninterrupted to 100%. This one full discharge-to-hibernate cycle resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every 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\"\u003eBIOS reporting battery health as poor after replacing the VGP-BPS30\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony VAIO firmware stores charge history and wear data in EEPROM on the original cell. When a new cell goes in, the BIOS reads no matching history and flags the battery as degraded or unknown. This is a firmware calibration issue, not a fault with the replacement. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%. After two to three cycles, the BIOS learn cycle completes and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\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 discharge curve. The old calibration data maps the wrong voltage points to percentage readings, so the system hits the low-voltage shutdown threshold well before the gauge reaches 0%. It is not a cell defect. Run two or three full discharge-to-hibernate cycles without interrupting the charge phase. By the third cycle the fuel gauge IC recalibrates and the shutdowns stop — check that the resting voltage reads 11.1V or above after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409805246554,"sku":"BWCS-BPS30NB-1","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409805279322,"sku":"BWCS-BPS30NB-2","price":153.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409805312090,"sku":"BWCS-BPS30NB-3","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS30NB-1.webp?v=1779580971","url":"https:\/\/batteryweb.com\/products\/sony-vaio-svt-11-replacement-battery-111v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
