It fits the MacBook Pro 15\" MA610B\/A and a wide range of other 15-inch MacBook Pro models from the same generation. If your original battery no longer holds a charge or the system reports degraded health, this cell restores full portable operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMacBook Pro 15\" first-generation platform:\u003c\/strong\u003e\n    These models share the same A1175 battery bay, connector pinout, and BMS communication protocol. The logic board expects a specific handshake over the SMBus line — this cell passes that handshake without modification or adapter.\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 MacBook Pro 15\" logic board. The BMS accepted the cell, the SMBus handshake completed correctly, and the charge controller reached full capacity without tripping a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on macOS:\u003c\/strong\u003e\n    After fitting this cell, run the system down to automatic hibernate, then charge uninterrupted to 100% before unplugging. This forces the fuel gauge IC to map its readings against the new cell's actual charge curve 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\"\u003eWhy macOS shows \"Service Battery\" immediately after a new A1175 install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MacBook Pro stores battery health data in EEPROM on the logic board — not on the cell itself. When you swap the physical cell, the EEPROM still holds the cycle count and degradation data from the old battery. macOS reads that stored data and flags poor health before the new cell has run a single cycle. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and allows the SMBus fuel gauge to write fresh calibration data to EEPROM.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMacBook Pro 15\" shutting down at 20–30% battery remaining 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 voltage curve. The IC is still using the old cell's discharge profile, so it predicts empty earlier than actual depletion — but the cell voltage also drops sharply under full CPU and display load near the lower end of its range. The system interprets that voltage sag as a critical cutoff and shuts down rather than risking an uncontrolled discharge. Run two to three full discharge-to-hibernate and full-charge cycles until the OS fuel gauge stabilises — after calibration, the shutdown threshold should resolve back to below 5% remaining.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410844581978,"sku":"BWCS-AM1175NB-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410844614746,"sku":"BWCS-AM1175NB-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410844647514,"sku":"BWCS-AM1175NB-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AM1175NB-1.webp?v=1779581319","url":"https:\/\/batteryweb.com\/products\/apple-macbook-pro-15-ma610ba-replacement-battery-108v-5800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
