5 Things to Know About MacBook Air Battery Replacement

Replace the battery when the cycle count exceeds 1000 Apple rates the battery for 1000 charge cycles before it drops below 80% of its original capacity.

Check cycle count in System Settings or System Information On macOS Ventura and later, go to System Settings > Battery > Battery Health. On older versions, click Apple logo > About This Mac > More Info > System Report > Hardware > Power, and look for “Cycle Count.”

Do not fixate on the cycle count alone If your MacBook Air dies faster than it used to, replace the battery even if you are under 1000 cycles.

Replace the battery if you see the “Service Recommended” warning This warning in the battery menu means the battery needs replacement regardless of cycle count.

Weather and charging habits affect battery life These factors can degrade the battery faster than the cycle count suggests, so pay attention to real-world performance.
