There are a few things you can do to check your Mac’s battery health and get more information about the status of your battery.
First, you can check your Mac’s battery health in the “About This Mac” dialog. To do this, click the Apple menu in the top left corner of your screen and select “About This Mac.” In the “Overview” tab, you should see information about your Mac’s model, operating system, processor, memory, and storage.
Scroll down to the “Hardware” section and click on the “Battery” entry. Here, you should see your Mac’s battery health as well as information about its design capacity and maximum capacity. If your Mac is running macOS Mojave or later, you’ll also see a “Cycles” entry that indicates how many times your Mac has been discharged and recharged.
If you want even more information about your Mac’s battery health, you can use the “System Information” application. To do this, open the “Finder” application and click on the “Application Utilities” folder. Double-click on the “System Information” icon to launch the app.
In the System Information app, expand the “Hardware” section in the sidebar and then click on “Power.” In the power section, you should see information about your Mac’s current charge level as well as its maximum capacity (in mAh) and design capacity (in mAh). You should also see an entry for “Cycles,” which indicates how many times your Mac has been discharged and recharged.
Checking Battery Health in System Preferences
There are two ways to check your Mac battery health: in System Preferences or by using the Terminal.
In System Preferences, click on Battery in the Hardware section. You will see your battery’s current charge and condition. If you mouse over the graph, you will also see your maximum capacity as a percentage of the original capacity.
To check your battery health using the Terminal, open the Terminal application and type in the following command:
defaults read /Library/Preferences/com.apple.iokit.BatteryAgent | grep MaxCapacity
This will give you your current maximum capacity as a percentage of the original capacity.
Checking Battery Health from the Terminal
In this article, we’ll show you how to check your Mac battery health from the Terminal.
First, open the Terminal. You can find it in the Utilities folder in your Applications folder.
Once the Terminal is open, type in the following command:
ioreg -w0 -l | grep Capacity | tr ‘
‘ ‘\n’ > ~/Desktop/battery_health.txt
This command will create a text file on your Desktop with information about your battery’s capacity.
Next, open the file in a text editor (like TextEdit or Microsoft Word) and look for the “Capacity” line. The value next to this line is your battery’s current capacity, expressed as a percentage.
For example, if the value next to “Capacity” is 90%, that means your battery is still working fine and doesn’t need to be replaced yet. However, if the value is below 80%, that means your battery might need to be replaced soon.
Checking Battery Health with Third-Party Apps
If you want to get more detailed information about your Mac’s battery health, you can check it using a third-party app. There are a few different options available, but one of the most popular is coconutBattery.
To use coconutBattery, simply download and install the app. Once it’s up and running, you’ll see information about your Mac’s current battery health as well as its maximum capacity. This can be helpful in determining whether or not it’s time to replace your battery.
Other apps that can be used to check your Mac’s battery health include iStat Menus and Battery Monitor.
In conclusion, there are a few different ways to check your Mac battery health. You can use Apple’s built-in tools, third-party apps, or the terminal. Each method has its own advantages and disadvantages, so choose the one that’s right for you.

Tips for Maintaining Battery Health
Your Mac’s battery health is something you should regularly check to ensure that it is running correctly and to prevent any future issues. There are a few things you can do to help maintain your battery’s health.
Firstly, avoid exposing your Mac to extreme temperatures, both hot and cold. Secondly, ensure that you regularly update your Mac’s software as well as any apps that you use; this will help to prevent any conflicts that could drain your battery. Finally, calibrate your Mac’s battery at least once a year; this helps to keep the battery indicator accuratle.
If you follow these simple tips, you can help extend the life of your Mac’s battery and avoid any future problems.
Warning Signs of a Failing Battery
There are several warning signs that will indicate your Mac battery needs to be replaced. The first and most obvious sign is a significant decrease in battery life. If you notice that your Mac isn’t holding a charge as long as it used to, it’s time to get a new battery.
Another sign of a failing battery is the appearance of the battery icon in the menu bar. If you see a battery icon with an “X” through it, that means your Mac’s battery is not healthy and needs to be replaced.
You may also notice that your Mac is running hot more frequently than usual. This is because a failing battery won’t dissipate heat as effectively as a healthy one, and the extra heat can cause performance issues. If you find that your Mac is running hot even when you’re not doing anything intensive, it’s time for a new battery.
Finally, you may hear strange noises coming from your Mac, such as clicking, whirring, or grinding. These noises are caused by the fan kicking on more frequently to cool down the overheating internal components. If you hear any strange noises coming from your Mac, make sure to get it checked out by an Apple Store or an authorized service provider as soon as possible.
How to Replace a Mac Battery
