It replaces OEM part numbers VGP-BPL2A\/S, VGP-BPL2C\/S, VGP-BPS2A\/S, and VGP-BPS2C\/S. Compatible models include the VGN-C140G\/B, VGN-C150P\/B, VGN-C190, VGN-C190P\/H, and over 70 additional VAIO VGN-C variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVGN-C series platform fit:\u003c\/strong\u003e\n    These VAIO models share a common battery bay geometry, 11.1V three-cell rail, and the same BMS connector pinout. That is why one replacement battery covers the full VGN-C lineup — the charge management handshake and physical latch points are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a VGN-C series unit and cycled it through charge, idle draw, and load conditions. The BMS responded correctly to charge termination signals and did not trip under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the VGN-C series:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle. Skipping this step is the main reason the VAIO BIOS reports a poor health warning or inaccurate capacity reading after a 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 battery health as poor after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Sony VAIO BIOS stores battery health data in EEPROM and compares it against the previous cell's charge history. A new cell has no matching history, so the BIOS flags it as degraded or unknown — this is a data mismatch, not a fault with the replacement battery. The fix is a calibration cycle: discharge fully to hibernate-cutoff, then charge uninterrupted to 100% without interruption. After one or two full cycles, the fuel gauge IC recalibrates against the new cell and the BIOS health warning clears. Check that the reported capacity reaches at least 95Wh after calibration — that confirms the EEPROM has updated correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot sustain voltage under combined CPU and display load — the voltage drops below the BMS cutoff threshold before the fuel gauge reaches 0%. It is a voltage cliff, not a capacity problem. On the VGN-C series, running a full discharge-to-hibernate calibration cycle corrects the fuel gauge so the reported percentage aligns with actual cell voltage. If shutdowns persist after two calibration cycles, check the battery voltage at the point of cutoff — it should be no lower than 9.9V (3.3V per cell) under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410813550682,"sku":"BWCS-BPS2ADB-1","price":133.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410813583450,"sku":"BWCS-BPS2ADB-2","price":153.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410813616218,"sku":"BWCS-BPS2ADB-3","price":169.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS2ADB-1.webp?v=1779581182","url":"https:\/\/batteryweb.com\/products\/sony-vaio-vgn-c140gb-replacement-battery-111v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
