MacBook Battery A1618 - OEM Quality For MacBook Pro 15‑Inch
This is an OEM quality replacement battery pack for MacBook Pro 15‑inch Retina (Mid 2015) that restores original endurance and stable power delivery. The pack is built to the A1618 specification with a rated 99.5 Wh capacity at 11.36 V, using a six‑cell lithium‑polymer array that fits the factory footprint and clears the speakers and trackpad frame without modification.
The smart fuel gauge communicates natively with macOS and SMC for accurate percentage, cycle count, and battery health reporting. High grade cells are matched for internal resistance and balanced charging, and the protection board provides overcharge, over‑discharge, overcurrent, and short‑circuit safeguards for dependable bench testing and long‑term use.
Compatibility And Technical Data You Need
Model reference is A1618. Chemistry is lithium‑polymer. Nominal voltage is 11.36 V. Rated energy is 99.5 Wh. Cell count is 6. Interface is a factory‑style flex with a board‑mounted connector that mates to the logic board without adapters. Expected service life is 800+ cycles to 80% of original capacity under normal use. Compliance meets CE and RoHS requirements and is shipped to UN 38.3 transport standards.
Device compatibility covers MacBook Pro 15‑inch Retina (Mid 2015) model A1398, including EMC 2909 and 2910. This pack replaces battery identifier A1618 only and is not cross‑compatible with A1494 units used in the 2013–2014 A1398 revisions. Use MagSafe 2 chargers as originally supplied with the machine for best performance and thermal behavior.
Installation Guidance For Repair Shops
Plan 45–90 minutes of bench time depending on adhesive condition. Fully power down, disconnect the logic board battery connector first, and remove or protect the trackpad flex before releasing the cells. Use adhesive remover or controlled heat and plastic cards to separate the cell banks from the top case, avoid prying near the keyboard rivets or speaker enclosures. Clean residual adhesive thoroughly so the new pack seats flat and does not preload the trackpad.
Dry‑fit the array, connect the flex, secure the connector shield, and apply uniform pressure across all cell banks to bond. Perform an SMC reset after reassembly, then calibrate by charging to 100%, resting on charge for at least two hours, and completing one to two full discharge and recharge cycles. Verify system information shows the correct design capacity near 99.5 Wh and a count of zero before returning the unit.
Use Cases And Service Benefits
Choose this A1618 when you need predictable runtime recovery on 2015 fleets, trade‑ins, and corporate refresh projects, or when addressing swelling that lifts the trackpad or causes palm rest gaps. Replace units that report a high cycle count, rapid drop under load, unexpected shutdowns at 20–40%, or persistent “service battery” status even after software updates.
Standardizing on an OEM quality A1618 simplifies inventory, reduces repeat returns, and supports consistent macOS battery diagnostics across mixed refurb batches. You get stable power delivery under sustained workloads typical of 15‑inch models, clean fitment without chassis stress, and straightforward calibration that aligns with the original charging profile.
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: A1398
