It fits the A1297 chassis across 2009 and later versions, including MC226 and MD311 configurations. OEM part numbers covered include A1297, A1383, and 020-7149-A.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMacBook Pro 17 A1297 compatibility:\u003c\/strong\u003e\n    All A1297 chassis revisions from 2009 through 2011 share the same battery bay dimensions, six-pin Smart Battery connector, and 10.95V power rail. The SMC communicates with the battery over SMBus — the BMS on this cell speaks that protocol correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an A1297 logic board and confirmed the SMC recognised it without faults. The BMS held charge regulation cleanly across a full cycle, and the SMC did not throw a Service Battery alert during the test run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSMC calibration after install:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it reaches hibernate cutoff, then charge uninterrupted to 100%. This resets the SMC battery learn cycle and prevents the inaccurate health warning macOS displays after any cell swap on this model.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy macOS reports \"Service Battery\" immediately after fitting a new A1383 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe A1297 SMC reads cycle count, full-charge capacity, and design capacity from the battery's EEPROM on first boot. A new cell carries factory EEPROM values that do not match the learned data from the old cell, so the SMC flags a mismatch. This is not a fault with the replacement — it is a data conflict. Running one full discharge-to-hibernate followed by a complete uninterrupted charge clears the flag by giving the SMC a fresh dataset to write. After two to three cycles, the health indicator stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMacBook Pro 17 shutting down abruptly at 20–30% charge shown\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 gauge predicts 20–30% remaining based on the old cell's characteristics, but the new cell's voltage drops faster under full CPU and display load — the SMC sees a low-voltage cliff and shuts down before the displayed percentage reaches zero. The fix is calibration: discharge fully to hibernate cutoff, then charge to 100% without interruption. Repeat this cycle twice more, and the fuel gauge IC recalculates the curve against the actual cell chemistry. After three full cycles, shutdowns at false percentages stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409792598106,"sku":"BWCS-AM1383NB-1","price":136.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409792630874,"sku":"BWCS-AM1383NB-2","price":158.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409792663642,"sku":"BWCS-AM1383NB-3","price":173.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AM1383NB-1.webp?v=1779580871","url":"https:\/\/batteryweb.com\/products\/apple-macbook-pro-17-replacement-battery-1095v-6900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
