MacBook Battery A1527 - OEM Quality For MacBook 12-Inch Retina
Get a dependable drop-in replacement with the MacBook Battery A1527 - OEM Quality, purpose-built for the MacBook 12-inch Retina A1534 (Early 2015). Designed to meet original performance, this pack delivers consistent runtime, stable charging behavior, and accurate percentage reporting so you can return devices to customers with confidence.
Each unit is assembled with new grade-a lithium-polymer cells, a calibrated fuel gauge and a low-impedance power path for steady output under burst loads. You get a zero-cycle battery that supports native macOS battery management and sleep behaviors, helping you close tickets faster and reduce comeback risk.
Key technical data and compatibility
Rated capacity is 39.7 Wh at 7.55 V nominal, with a typical 5200–5300 mAh equivalent depending on test method. Cell chemistry is lithium-polymer with a multi-cell terraced layout, engineered to fit the 12-inch lower case footprint while maintaining thermal stability and balanced discharge across packs.
Cycle life is rated for up to 1000 full charge cycles with ≥80% capacity retention under standard usage. The pack integrates a smart gas gauge controller with protection for overcharge, overdischarge, overcurrent, temperature. The connector is a board-mounted flex with factory terminations for a direct fit in the A1534 2015 logic board. The battery is compatible with MacBook 12-inch Retina A1534 Early 2015 only, and it is not cross-compatible with later A1534 revisions.
Built for repair workflows and long-term reliability
Quality control includes cell matching by internal resistance, 72-hour charge and hold verification, and end-of-line calibration to ensure the percentage readout aligns with actual capacity. Adhesive tapes are pre-applied on each cell section to simplify placement and reduce installation time, and the pack arrives at a storage charge so you can immediately run post-repair diagnostics.
Protection features keep voltage and current within safe limits during initial boot and system updates, minimizing brownout on boards that have been reworked. Stable impedance also supports consistent peak draw during high-load tasks like OS installation and indexing, which helps you validate the repair before handoff.
Installation notes, safety, and packaging
Use isopropyl alcohol or an adhesive remover to release the original pack and avoid prying near the trackpad ribbon. Disconnect the battery before any board work, and torque screws to factory spec after alignment to prevent cell stress. Calibrate by charging to 100%, resting for 2 hours, then cycling around 5–10% and recharging to full once to sync the gauge.
Units ship in ESD-safe packaging with UN 38.3, CE, and RoHS compliance, and they include date codes for batch traceability. Recommended storage is 15–25°c at 40–60% state of charge, and recommended operating charge temperature is 0–35°c. If you service fleets, you can stage multiple MacBook Battery A1527 - OEM Quality units with consistent results across builds, ensuring predictable runtime and customer satisfaction.
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: A1534
