It replaces OEM part numbers VGP-BPS26A, VGP-BPS26, and VGP-BPL26. Install it when the original cell no longer holds a charge or the laptop has become effectively desk-bound.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVAIO VPC-CA series compatibility:\u003c\/strong\u003e\n    All VPC-CA variants share the same 11.1V three-cell rail, identical connector pinout, and the same BMS handshake protocol — that is why one battery covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a VPC-CA26EC and confirmed the BMS negotiated correctly with the VAIO EC firmware, charge acceptance reached full rated capacity, and no protection trips occurred across the full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates from low charge, then charge uninterrupted to 100% before using it again. 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 a fresh cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe VAIO BIOS reads health data from the battery's EEPROM, which stores the charge history of the old cell. When a new cell is fitted, that EEPROM data does not match actual capacity yet, so the BIOS flags the battery as degraded or unknown. This is a data mismatch, not a fault with the replacement cell. Running one complete discharge-to-hibernate followed by a full uninterrupted charge allows the BIOS to rewrite its learned capacity baseline and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down hard at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated to the new cell's voltage curve. The gauge reports 20–30% remaining, but the actual cell voltage has already dropped below the BIOS cutoff threshold under combined CPU and display load. The VAIO does not step down gracefully — it cuts power immediately to protect the cell. Run two full calibration cycles and the gauge IC will align its readings to the real voltage floor; shutdowns will stop occurring above the 5% warning threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410739953754,"sku":"BWCS-BPS26HB-1","price":143.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410739986522,"sku":"BWCS-BPS26HB-2","price":166.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410740019290,"sku":"BWCS-BPS26HB-3","price":183.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS26HB-1.webp?v=1779581042","url":"https:\/\/batteryweb.com\/products\/sony-vaio-vpc-ca16ec-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
