Key Takeaways

  • MacBook batteries typically last a few years before their capacity diminishes, so you may need to replace your battery even if your machine is in good condition.
  • You can check your MacBook's battery status to see if it's time for a replacement, paying attention to the Battery Health and Maximum Capacity indicators.
  • If your MacBook is still under warranty, Apple will replace a faulty or degraded battery for free. If not, you have options such as paying for an Apple battery replacement, going to a third-party repair shop, or replacing the battery yourself.
