What this battery replaces

The GOLDIX A1527 is a new lithium-ion replacement for the internal battery used in 12 inch Retina MacBook models identified as A1534, A1705 and EMC 2746, 2991 or 3099. It suits owners of Early 2015, Early 2016 or Mid 2017 units who need a direct swap for the original Apple part numbers A1527, A1534 and A1705.

Voltage and capacity match

The cell delivers 7.55V and 5263mAh, which equals 39.71Wh, matching the factory specification for the supported MacBook models. If your machine requires a different voltage or a higher watt-hour rating this unit will not be compatible, so verify the part number on your existing battery before ordering.

Installation notes and common issues

Replacing the battery requires opening the MacBook case and disconnecting the original pack, which involves small screws and a fragile ribbon connector. The most frequent problem is damaging the connector or forgetting to reseat it fully, leading to a no-power condition after reassembly. Take photos of each step and use the correct screwdrivers to avoid stripped heads.

Questions about this item

How many hours will the 39.71 Wh rating actually run my MacBook 12 inch Retina?

The 39.71 Wh rating measures total energy stored; real runtime depends on the MacBook's power draw, which varies with processor model (1.1 GHz to 1.4 GHz), screen brightness and workload, so a single hour figure cannot be given.

Does the 7.55 V output match the original MacBook 12 inch Retina power connector and charging circuit?

Yes, the 7.55 V lithium-polymer pack is built to the A1527 / A1534 specification and connects to the same internal flex cable used in Early 2015, Early 2016 and Mid 2017 models.

Will this battery fit inside the MacBook 12 inch Retina case without modification?

The pack is shaped to the factory A1527 form factor and aligns with the existing screw holes and connector position for A1534, EMC 2746, 2991 and 3099 units.
