Compatible MacBook Pro 13 Retina models
This 2-Power A1582 lithium-ion battery replaces the original power source in MacBook Pro 13 inch Retina A1502 units from Late 2013, Mid 2014 and Early 2015. It matches part numbers including MJLU2LL/A, MF839LL/A, MF841LL/A, MGX92LL/A, MGX72LL/A, ME864LL/A and ME867LL/A. The pack delivers 11.42 volts and 74.9 watt-hours through a standard connector.
Installation experience and common issues
The package includes free screwdrivers and crowbars so you can open the bottom case and swap the battery without sourcing extra tools. The procedure requires removing several small screws and disconnecting the battery flex cable; the most frequent issue is stripping the tiny screw heads if the wrong driver size is used. Take care not to puncture the soft pouch cells when prying the old pack out.
Practical limits of the lithium-ion pack
Rated at 500 recharge cycles, the cell chemistry will gradually lose capacity after repeated full charges. Operation time per charge ranges from 1.5 to 3 hours depending on workload, screen brightness and background tasks. The battery is not compatible with MacBook Pro 13 models before Late 2013 or with 15 inch Retina units, and it cannot be charged by a 20 volt 100 watt AC adapter intended for larger laptops.
