Compatible MacBook Air models

This KingSener A2389 replacement battery fits the 13 inch MacBook Air model A2337 released in 2020 with the M1 chip. It covers part numbers MGN53, MGN63, MGN73, MGN83, MGN93, MGND3, MGNA3 and MGNE3. It is not for earlier Intel models or later M2 designs.

Capacity and voltage match

The battery delivers 49.9Wh at 4380mAh with a nominal voltage of 11.39V. These figures must match the original Apple part 616-00535 exactly or the Mac will not recognise the pack. Buyers who need a different watt-hour rating cannot use this unit.

Installation notes

Replacing the pack requires removing the bottom case and disconnecting the logic-board connector before fitting the new cell. Adhesive strips hold the battery in place; rushing this step often damages the trackpad cable. Buyers without the correct screwdrivers or adhesive should seek professional fitting.

Questions about this item

How does the 49.9 Wh capacity translate to daily runtime on the MacBook Air A2337 M1?

The 49.9 Wh rating matches the original Apple specification, so you can expect the same battery life you had when the laptop was new — typically a full day of light work or several hours of heavier use.

What connector standard does the A2389 battery use and what does it limit?

It uses Apple's proprietary multi-pin connector for the A2337 logic board; this limits installation to that exact MacBook Air 13 inch M1 2020 model family and prevents use in any other laptop.

Will the A2389 fit inside the MacBook Air A2337 case without modification?

Yes — the battery is built to the original A2389 form factor and screw-hole layout, so it drops into the existing battery bay of the MacBook Air 13 inch A2337 M1 2020 without any trimming or adapters.
