In this review the TREE.NB A1527 A1534 replacement battery is assessed as a direct-fit option for owners of the 12-inch MacBook A1534 models from Early 2015 through Mid 2017. The bottom line: it is a practical, cost-conscious replacement that matches the original physical fit and offers a strong capacity of 72Wh, making it a sensible choice for users who need a refurbished-life battery with good energy density. The review focuses on compatibility, installation, and realistic expectations for longevity.

Key Features

• Compatibility: Designed to replace A1534 and A1527 series part numbers so it fits the 12-inch MacBook models from 2015 to 2017 without modification.
• Capacity: The 72Wh rating provides higher energy than many aftermarket options, which can translate to longer unplugged use when installed correctly.
• Cell count: A six-cell configuration balances energy density and physical fit to match the original battery layout of the MacBook 12-inch.
• Voltage: With a nominal 10.8V output it interfaces properly with the MacBook power management system when the correct model is used.

Who It's For

This battery is for owners of the 12-inch MacBook model A1534 (Early 2015, Early 2016, Mid 2017) who need a direct replacement that matches the original pack shape and connector. It suits users comfortable with a hardware replacement or who have access to a technician, and who want higher capacity than some low-cost alternatives.

Customers who should look elsewhere include people with non-MacBook laptops or those uncertain about model numbers; compatibility is specific to A1534/A1527 variants and customers reporting use with other brands have had issues. If long-term OEM support or guaranteed Apple service is required, consider official service channels.
