MacBook Air 15" M2 A2941 (2023) Battery Replacement
Compatible models: A2941, EMC 8103
The MacBook Air 15-inch M2 was Apple's first 15-inch MacBook Air, released in 2023 with the largest battery of any Air at 66.5Wh. The bigger display draws more power than the 13-inch version, and Apple balanced this with the larger cell to maintain the 18-hour claimed runtime. Zoom calls, streaming, external display use and Continuity Camera all increase real-world consumption. A degraded battery on the 15-inch is particularly noticeable because the screen is always on and demanding attention, and the gap from 18 hours to 6 or 8 is impossible to ignore.
- Turnaround: Same day where possible, subject to stock and workload
- 6-month warranty on the replacement battery
- Walk-in near Liverpool Street Station or use our UK mail-in service
Signs your MacBook Air 15" M2 battery may need replacing
The M2 chip is efficient, but the 15-inch display is a persistent drain in a way the 13-inch is not. Users who rely on the larger screen for presentations, video work or split-screen productivity find their battery health declining faster than colleagues using the 13-inch version.
- Battery draining significantly faster than it used to
- Device shutting down unexpectedly, particularly at lower charge percentages
- Only running reliably when connected to power throughout the day
- Battery percentage dropping suddenly or behaving inconsistently
- MacBook running warmer than usual during normal tasks
- Screen lifting slightly from the chassis (can indicate a swollen battery, book as soon as possible)
- Fan-less design running noticeably warmer than usual during everyday tasks, suggesting the battery is under more thermal stress than it should be
- Go to Apple Menu > About This Mac > System Information > Power, then check Cycle Count and Condition
What is included
- Safe removal of the bottom case and existing battery
- Fitting of a quality replacement 66.5Wh battery cell
- Post-repair charging and power stability checks
- Full function test covering power, MagSafe 3 charging, keyboard, trackpad and display
- 6-month warranty on the replacement battery
How to confirm your model
