It replaces OEM part PA5212U-1BRS and cross-references PABAS283, PA5247U-1BRS, PA5265U-1BRS, PA5291U-1BRS, and several other Toshiba PABAS codes. If the original cell no longer holds charge or the laptop dies on battery, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA30-C and A40-C platform fit:\u003c\/strong\u003e\n    Both series share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS handshake protocol. A single cell covers the full A30-C and A40-C range despite different chassis SKUs — the voltage rail and communication lines are identical across the platform.\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 Satellite Pro A40-C unit. The BMS negotiated correctly with the Toshiba EC firmware, the charge controller accepted the cell without error codes, and capacity registers matched the rated 32.56Wh within normal tolerance.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on Toshiba EC firmware:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on low battery, then charge uninterrupted to 100%. This forces the embedded controller to relearn the cell's actual capacity curve and clears the inaccurate battery health warning that appears after every cell replacement 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\" immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Toshiba BIOS reads health data from the battery's EEPROM, which stores cycle count and degradation flags from the previous cell. When a new cell is installed, the EEPROM values don't match the fresh chemistry, so the BIOS flags it as degraded before any cycles have run. This is a firmware interpretation issue, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle. After two to three full cycles, the health indicator typically corrects to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down 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 against the new cell's actual discharge curve. The IC carries over voltage-to-percentage mapping from the old, degraded cell, so it misreads remaining capacity at higher percentages. Under full CPU and display load, the actual cell voltage drops faster than the gauge expects, and the protection circuit cuts power before the displayed percentage reaches zero. Run two to three full discharge and charge cycles — calibration typically stabilises by the third cycle, and the laptop will hold until the gauge reads below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410736185434,"sku":"BWCS-TOA500NB-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410736218202,"sku":"BWCS-TOA500NB-2","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410736250970,"sku":"BWCS-TOA500NB-3","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TOA500NB-1.webp?v=1779580663","url":"https:\/\/batteryweb.com\/products\/toshiba-satellite-pro-a30-c-1f3-replacement-battery-148v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
