Almost every modern MacBook, MacBook Pro, and MacBook Air is rated for 1,000 battery cycles.Įven if these numbers look healthy, you may have noticed your battery life has become significantly worse of late and decide that it's time for a replacement anyway.

Different MacBooks have varying ratings for cycle counts, so you'll need to cross-reference your result with the ratings on Apple's battery cycle support page.

This number shows how many times your battery has gone from 100 percent to fully drained.
