The MacBook Pro 13″ Retina Mid 2015 (Model A1502 – EMC 2835) uses a 6-cell Li-Polymer battery with a typical capacity of 6559mAh; the original Apple part number is A1493.
This OEM battery matches the exact dimensions and connector position, ensuring proper fit without chassis modification.
Replacement involves removing the bottom cover, disconnecting the old battery (which is strongly adhered), and reapplying new adhesive for the replacement unit.
macOS recognizes the new battery immediately and activates native power management features without requiring firmware resets or additional configuration.
The battery supports 800–1000 charge cycles, operates safely without overheating, and typically charges fully within 2 hours.
Initial calibration is recommended: charge to 100%, drain to 5–10%, and then recharge to full once.
