MacBook Air 13" M1 A2337 (2020) Battery Replacement
Compatible models: A2337, EMC 3598
The MacBook Air 13-inch M1 was the machine that demonstrated what Apple Silicon could do. Its battery life was dramatically better than any previous Air, and the fanless M1 chip handled everyday tasks without ever spinning up a fan. That exceptional performance from a 49.9Wh cell is partly why degradation is so noticeable when it comes. Users who were getting 12 to 15 hours notice the change sharply when the same tasks now drain the battery in half the time. Replacing the battery restores the M1 experience that made this machine a genuine step forward.
- Turnaround: Same day where possible, subject to stock and workload
- 6-month warranty on the replacement battery

Signs your MacBook Air 13" M1 battery may need replacing
The M1 chip is extremely efficient, which means a degraded battery on this machine feels more dramatic than on older Intel models. The contrast between a healthy and worn M1 battery is one of the starkest in Apple's laptop range.
