What Should I Know About Mac Battery Information? 

It can be confusing to know what cycle counts mean and what charging capacity entails. Here's a look at what you need to know.

  • Cycle count explains how many times you've fully recharged. All modern Macs are rated for 1,000 cycles with much older models rated for 500 or 300 cycles. The battery doesn't suddenly fail when it reaches that limit but it does mean that it won't work as effectively so it's wise to replace it at this stage.
  • Charging capacity is king. Basically, the charging capacity shows how much room there is on the battery for storing power. It tends to gradually go down a little the older the battery gets so it's useful to keep an eye on how it's performing. 
  • Battery health condition is a simple guide to what to do next. If it says Normal, you're good to go. If it says Replace Soon, then consider a visit to the Genius Bar to discuss a replacement soon. Replace Now or Service Battery means you definitely need to get your battery fixed if you want it to last as long as it used to. 

Before checking anything to do with the Mac's battery health, it's recommended that you calibrate your battery beforehand to ensure you get the most accurate results and the best performance.
