MacBook Battery A1582 - OEM Quality For MacBook Pro 13-Inch
Choose MacBook Battery A1582 - OEM Quality when you need stable runtime, correct gas‑gauge reporting, and a clean fit in the chassis. This pack delivers a typical 74.9 wh capacity at 11.42 v, translating to roughly 6550 mah, so you restore the working endurance your customers expect from a healthy 2015 13‑inch retina unit.
Cells are grade a lithiumpolymer with matched impedance and a calibrated bms that supports overcharge, over‑discharge, overcurrent, and thermal protection. The cycle count is brand new and ready to pair with the smc without firmware tweaks, and it is rated for long service life when used within normal charge ranges and temperatures.
Technical Data You Can Trust
Model: a1582. Chemistry: li‑polymer. Nominal voltage: 11.42 v. Capacity: 74.9 wh (approx. 6559 mah). Cable and connector: board‑matched flex for the a1502 logic board. Protection ic: ti‑based controller with secondary cutoff. Expected cycle life: up to 1000 cycles under proper usage. Operating temperature: 0–35°c. Storage temperature: 15–25°c at 40–60% state of charge. Color: black multi‑cell pack with preformed segments for the palm rest cavities.
Quality markers include low self‑discharge cells, accurate state‑of‑charge reporting, and balanced pack assembly for even across segments. Every pack is electrically tested for capacity, voltage, and standby drain before shipping, so you can drop it into workflow without extra screening steps.
Compatibility And What To Watch
Designed for MacBook Pro 13‑inch retina early 2015 only. Device model: a1502. Emc: 2835. Model identifier: macbookpro12,1. Do not use with late 2013 or mid 2014 units that ship with a1493, since the harness and pack geometry differ. a1582 communicates natively with macos battery management and the original smc, so sleep, wake, and percentage reporting remain accurate.
Typical post‑install calibration is simple. Charge to 100%, keep it on the charger for two hours, use down to around 5–10%, and then charge uninterrupted to full again. This aligns the coulomb counter with the pack’s actual capacity for better runtime estimates.
Repair Notes For Faster Turnaround
Plan 45–90 minutes for a clean replacement on adhesive condition. Use p5 pentalobe for the bottom case, t5 torx for internal screws, and plastic cards or a dedicated adhesive remover to lift the old cells without stressing the top case, trackpad, or speakers. Shield the trackpad flex, work cell by cell, and avoid prying near the keyboard rivets. Always disconnect the battery before logic board work and observe esd precautions.
Recommend returning the unit with a balanced charge between 40–60% for handover or storage. Advise normal operating use between 20–80% for best longevity, and avoid extended heat exposure. With MacBook Battery A1582 - OEM Quality you get the correct fit, the right connector, and the capacity that keeps a 2015 13‑inch retina productive after refurb or repair.
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: A1502
