MacBook Battery A1494 - OEM Quality For A1398 15-Inch
Get the capacity and fit you expect with MacBook Battery A1494 - OEM Quality for the 15‑inch MacBook Pro with Retina display. This pack delivers 95 wh at 11.26 v (approx. 8440 mah) using high grade li‑polymer cells in a 6‑cell configuration, matching the original energy profile and runtime targets. It is built for the A1398 platform used in late 3 and mid 2014 models, including model identifiers MacBookPro11,2 and MacBookPro11,3, so you can refurbish or service units with confidence.
The integrated battery management board provides accurate fuel gauging and hardware protections for overcharge, over‑discharge, overcurrent, and thermal events. The flex cable layout and footprint align with the factory adhesive footprint and cell geometry, ensuring proper clearances around the trackpad, speakers, and logic board once installed.
Detailed Specifications And Compatibility
Capacity is 95 wh, nominal voltage is 11.26 v, and typical capacity is 8440 mah. Chemistry is li‑polymer with a multi‑cell pack designed for slim topcase cavities. Expected cycle life is up to 1000 charge cycles under normal usage with proper calibration and thermal conditions. Standby drain and charge acceptance are tuned to the original macOS power management logic for smooth sleep and wake behavior.
Direct replacement part number is A1494 and it fits MacBook Pro Retina 15‑inch A1398 from late2013 and mid 2014. Compatible logic board identifiers include MacBookPro11,2 and MacBookPro11,3 across both integrated and discrete graphics variants. Use this pack to replace worn cells that show high cycle counts, rapid drop from 100% to 90%, swelling, or kernel power events related to low battery voltage under load.
Installation, Calibration, And Service Tips
Plan the job as a topcase‑in battery replacement because the cells are bonded to the upper case. Use adhesive remover or controlled heat only non‑metal cards to separate the cells, keeping clear of the trackpad cable and its connector. Disconnect the battery before any other board work, test fit the new pack before bonding, and verify trackpad click and cable routing. Torque speaker and bracket screws after the pack is seated to avoid pressure points on the cells.
Calibrate after install to stabilize the fuel gauge. Charge to 100% and keep it connected for two hours, use the MacBook until it automatically sleeps at low charge, let it rest for at least five hours, then recharge 100% without interruption. Reset the SMC using the built‑in keyboard shortcut for this generation to clear residual power states. Store spares at roughly 40‑60% state of charge in a cool, dry place, and advise end customers to avoid prolonged heat and deep discharge to extend cycle life.
Use Cases For Repair, Refurbishment, And Fleet Service
Replace fatigued A1494 units in workshop repairs where runtime is below expectations or macOS reports service battery. Refurbish A1398 inventory for resale with a fresh cycle count, stable idle drain, and predictable load performance for editing, development, or office workloads. Standardize on MacBook Battery A1494 - OEM Quality to keep parts bins simple and support both MacBookPro11,2 and MacBookPro11,3 configurations with one reliable pack.
Deploy in corporate or education fleets where consistent runtime and accurate percentage reporting reduce helpdesk tickets. Pair with thermal paste service and dust cleaning during the same session to return systems with improved acoustics and stable peak draw without voltage sag. You get a like‑for‑like electrical profile that integrates cleanly with macOS battery health features and diagnostics.
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: A1398
