MacBook Air 15-inch M2 & M3 (2023–2024) Battery Replacement

Apple MacBook Air

If your MacBook Air 15-inch M2 & M3 needs a battery replacement, our London technicians can help, usually with a quote on the same day you bring it in.

The 15-inch Air battery uses pull tabs and adhesive. We fit a new battery and check charging via MagSafe 3 and both USB-C ports.

The 15-inch Air has a larger battery than the 13-inch, split into more cells across the case. It still uses stretch-release tabs, so replacement is tidy.

About this model: The 15-inch MacBook Air (A2941 with M2, A3114 with M3) gives you a big screen in a thin, fanless body. The large, thin lid is its vulnerability: screens crack from drops and pressure.

Signs it needs a battery replacement

  • Service recommended
  • Poor battery life
  • Swelling
  • Not charging

How we do it

We start by reading your Mac’s battery cycle count and health, and testing the charger and port. A charging fault can mimic a worn battery, and we’d rather not sell you a part you don’t need.

Because the cells are bonded in place, we soften the adhesive and lift them slowly. Forcing a glued battery out is the main way these jobs go wrong.

Finally we check the new battery reports a healthy condition and a low cycle count, test charging, and recycle the old pack responsibly.

Questions we’re often asked

How long will the new battery last?

A new battery should give you close to the run time it had when new, and typically lasts several years with normal use. Keeping it away from long periods at 100% charge and high heat helps it age more slowly.

Will my data be safe?

Yes. We don’t wipe your Mac unless you ask. On this model the storage is encrypted and tied to its original board, so we never swap the board without explaining what that would mean for your data.

Do I pay if you can’t fix it?

No. If the repair isn’t possible, you don’t pay for it, and the free initial assessment costs nothing.
