How To Replace The Battery On A Macbook


Common MacBook Battery Issues

It’s easier than you think to drain your Macbook’s battery. If you find that your battery suddenly isn’t holding a charge for as long as it has been, the culprit could be as simple as overuse. The more time you spend on your computer, the faster your battery will begin to drain.

There are some settings that can help you preserve the battery life. Make sure your Bluetooth is turned off when it’s not in use. When this setting is turned on, it’s using unnecessary power in the background. Dim your screen brightness some if you can. The brighter the screen, the more power your MacBook is using. Turn off the keyboard backlighting feature. Unless you’re using your computer in the dark, you don’t need this turned on.

If you store your computer when the battery is at less than 50%, you could inadvertently be affecting the battery’s longevity. When you know you won’t be using your computer for a while, be sure to charge it to at least 50% before putting it away. And if for some reason you plan to store your computer longterm, be sure to charge it to 50% every six months to avoid losing battery capacity. Even if you’re not using your Macbook for a couple of days, be sure it’s charged. Apple states that when the Macbook’s lithium-ion battery is left for more than two days at less than 20%, the battery capacity will begin to deteriorate. So, if you go days without touching your computer, be sure to keep it juiced up. These are all little changes you can make that can end up having a big impact on your MacBook’s battery.

Replacing a MacBook Battery

Batteries lose their ability to hold a charge over time, and you don’t want to be left with a permanently dead laptop. Luckily, you can easily replace the battery on a MacBook by following our steps below.

  1. Check the condition of your MacBook’s battery. It’s really easy to do. Simply click on the battery icon in the menu bar and see what condition it is in. It will say one of four things:
  • Normal: everything is running smoothly.
  • Replace Soon: the battery is functioning normally but holds less charge than it did in its original condition.
  • Replace Now: the battery is still functioning normally but that it holds significantly less of a charge.
  • Service Battery: the battery is not functioning normally and needs to be taken in for service by a professional.
