MacBook Battery A1382 - OEM Quality For MacBook Pro 15-Inch A1286
The MacBook Battery A1382 - OEM Quality is a direct-fit replacement for MacBook Pro 15-inch A1286 models from early 2011, late 2011, and mid 2012. The pack delivers a nominal 10.95 V and 77.5 Wh, providing runtime that aligns with the original unit. The chemistry is lithium-polymer with a 3s2p configuration, giving a capacity of approximately 7080 mAh at 10.95 V. Each unit ships with the correct pre-installed board cable and mounting points for a clean, repeatable install.
The cell selection and battery management system are matched to Apple SMC expectations, so you get macOS percentage reporting, cycle count tracking, and smooth sleep and wake behavior. The pack is rated for up to 1000 charge cycles under normal use, making it a solid choice for refurbish projects and daily repair workflows where predictability matters.
Stable Power And Safe Design
The integrated protection board provides over-charge, over-discharge, over-current, short-circuit, and thermal safeguards to protect both the pack and the logic board. Matched low-impedance cells and tight voltage balance across series groups help maintain consistent discharge curves and reduce unexpected shutdowns at low state of charge.
The enclosure and cell padding mirror the original layout to minimize vibration and abrasion inside the unibody chassis. The connector and harness length follow factory geometry to avoid strain near the logic board socket during reassembly.
Full Technical Data For Repairs
The model number is A1382 and the chemistry is Li‑polymer. The nominal voltage is 10.95 V. The energy is 77.5 Wh, which is approximately 7080 mAh at the stated voltage. The configuration is 3s2p with integrated fuel gauge and SMC communication. The expected cycle life is up to 1000 cycles when charged between 20% and 80% and operated within normal temperatures. The operating temperature range is 10–35 °c for and 0–35 °c for use. The pack is CE, RoHS, and REACH compliant and is WEEE recyclable in the EU. The compatibility covers MacBook Pro 15‑inch A1286 early 2011, late 2011, and mid 2012 only, and it is not suitable for 2010 or retina models.
Repair-Friendly Fit And Best Practices
The installation is straightforward for shops familiar with unibody service and typically requires a tri‑wing y0 and a phillips00 driver. You should disconnect the magsafe adapter, power down, and isolate the battery connector before removing the old unit. You should seat the new pack flush, torque screws evenly, and verify that the harness is fully home without twisting. You should run a quick post‑install check in macOS for battery recognition, cycle count, and charging current.
The first calibration helps the fuel gauge learn the pack, so you should charge to 100%, keep it on charge for an additional two hours, use on battery down to around 5–10%, and then recharge to full without interruption. You should avoid prolonged storage at 0% and store around 40–60% state of charge if the unit will sit on a shelf. You should recycle the removed battery through approved WEEE channels to keep your workshop compliant and tidy.
The battery is covered with a 1-year product warranty. The warranty does not cover man-made damage or wear and tear. To be used with MacBook model number: A1286
