It fits models including the VGN-C140G\/B, VGN-C150P\/B, VGN-C190, and VGN-C190P\/H, along with 70+ additional VAIO C-series variants. OEM part numbers covered include VGP-BPL2A\/S, VGP-BPL2C\/S, VGP-BPS2A\/S, and VGP-BPS2C\/S.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVAIO VGN-C series compatibility:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell-series architecture and the same physical connector with identical BMS handshake signalling. One cell pack covers the full VGN-C line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a VGN-C series unit and confirmed the BMS negotiated correctly, accepted a full charge to 12.6V, and did not trigger a protection cutoff during CPU and display load testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation calibration on VAIO C-series:\u003c\/strong\u003e\n    After fitting this battery, run the notebook on battery power down to automatic hibernate, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the false \"poor health\" or \"unknown battery\" flag that commonly appears after any 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\"\u003eVAIO VGN-C shutting down at 20–30% charge remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a faulty cell. Under combined CPU and display load, the new cell's voltage drops faster than the fuel gauge IC expects based on the old cell's discharge curve. The BIOS interprets that voltage dip as a critically low state of charge and forces a shutdown — even though the gauge still reads 20–30%. Running two full calibration cycles trains the fuel gauge IC against the new cell's actual discharge profile and eliminates the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting incorrect Wh rating after fitting this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in BIOS or Windows battery report is read from EEPROM data embedded in the old cell's BMS chip — not recalculated from the new battery's actual chemistry. When you swap cells, the EEPROM value from the previous pack may persist in firmware until the learn cycle completes. After one full discharge-to-hibernate and uninterrupted charge to 100%, the system recalculates and displays the correct 73.26Wh rating. If the figure still reads incorrectly after two cycles, check that the battery connector is fully seated and the BMS contact pins are clean.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410813648986,"sku":"BWCS-BPS2AHB-1","price":121.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410813681754,"sku":"BWCS-BPS2AHB-2","price":139.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410813714522,"sku":"BWCS-BPS2AHB-3","price":152.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS2AHB-1.webp?v=1779581182","url":"https:\/\/batteryweb.com\/products\/sony-vaio-vgn-c140gb-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
