Interchangeable / Replacement Part Numbers

A1582, A1493, 020-8146, 020-8146-A, 020-8147-A, 020-8148, 020-8148-A, 020-8184, 020-00009, 020-00010, 020-00011, 613-00564-B, 661-8154, 661-02361

Some 613- and 661- references may identify the battery as part of a larger top-case service assembly rather than the loose battery alone. Confirm the original battery model, system EMC number, connector location, cell layout, and mounting arrangement before ordering.

⚠️ Critical A1493 and A1582 Revision Notice

The A1502 notebook designation was used across several production years with two different original battery revisions:

• A1493: Primarily associated with Late-2013 and Mid-2014 A1502 systems using EMC 2678 or EMC 2875. Original versions are commonly rated approximately 11.34V, 6330mAh, and 71.8Wh.
• A1582: Primarily associated with Early-2015 A1502 systems using EMC 2835. Original versions are commonly rated approximately 11.42V, 6559mAh, and 74.9Wh.

This listing is for an aftermarket battery specifically represented as a dual-revision A1493/A1582 replacement. Do not assume that every battery marked only A1493 or only A1582 fits every A1502 production year.

The A1502 number on the bottom case is not sufficient by itself to determine battery compatibility. Confirm the notebook’s EMC number, production year, model identifier, original battery number, connector position, cable routing, and physical cell layout.

A replacement carrying a slightly different milliamp-hour or watt-hour rating may still be compatible when it is specifically manufactured for the correct A1502 revision. Voltage, connector, battery-management electronics, mounting points, and physical layout must all match.

✅ Confirmed Compatibility

Compatibility with Late-2013 and Mid-2014 systems applies only when the supplied battery is the dual-revision version explicitly marked or sold for A1493 applications. Early-2015 compatibility requires A1582 or 020-8148 support.

⚙️ Fit and Installation Notes

• Confirm the notebook model is A1502 before ordering.
• Confirm the EMC number printed on the bottom enclosure: EMC 2678, EMC 2875, or EMC 2835.
• Confirm the original battery is marked A1493, A1582, or a matching 020-series reference.
• A1502 was used for multiple notebook generations and does not establish battery compatibility by itself.
• Late-2013 and Mid-2014 systems normally use the A1493 battery arrangement.
• Early-2015 systems normally use the A1582 battery arrangement.
• This listing covers both generations only when the supplied aftermarket battery is specifically manufactured as a dual-revision replacement.
• Compare the original connector, cable length, cable-routing direction, cell shape, mounting points, screw locations, and adhesive layout.
• The printed label, capacity marking, manufacturing code, and packaging may vary because this is an unbranded replacement product.
• Minor differences between 11.34V and 11.42V or between 71.8Wh and 74.9Wh may reflect the battery revision or aftermarket cell configuration.
• Do not substitute a battery merely because it has the same exterior shape or uses the A1502 system number.
• Internal battery replacement requires removal of the bottom enclosure and careful disconnection of the battery from the logic board.
• The battery cells are secured with strong adhesive and can be damaged by excessive force, sharp tools, bending, twisting, or puncturing.
• Professional installation is strongly recommended.
• Power off the notebook and disconnect the AC adapter before beginning installation.
• Do not install or reuse a swollen, punctured, leaking, overheated, or physically damaged battery.
• Replacement adhesive and installation tools are included only when specifically shown or stated.
• After installation, charge the battery fully and allow the operating system to complete normal battery calibration.
• Actual runtime and cycle life depend on processor load, display brightness, background activity, charging habits, temperature, and battery age.
• Recycle the removed lithium-polymer battery through an approved electronics or battery-recycling facility.
