3 Ways To Fix The Service Battery Warning On Mac

The MacBook you own consists of numerous components, but none are as active and vital as its battery. It undergoes significant strain and is influenced by various factors, thereby affecting its overall health. Consequently, encountering a Service Battery notification on your MacBook can be quite disconcerting.

In the following article, we will guide you through the process of resolving the Service Battery warning on your Mac. However, before delving into the solutions, let’s explore the diverse battery conditions that may be indicated.

Your Mac’s Battery Conditions Explained

Before we delve into the solutions, let’s highlight three battery conditions that signify the need for corrective measures. To quickly assess your battery’s status, simply select it from the Toolbar.

Pay attention to the following indicators:

  • Normal: This denotes that your battery is functioning without any discernible issues and is operating within standard parameters.
  • Replace Soon or Service Recommended: This warning suggests that your battery is operational but displaying signs of aging and wear.
  • Replace Now or Service Battery: At this stage, your battery is approaching the end of its lifespan and necessitates servicing or replacement.

There are several potential approaches to rectify the Service Battery warning on your Mac. However, before reaching for your toolkit, it’s advisable to perform another crucial check.

How to Check the Battery Cycle Count on Your MacBook

Laptop batteries, including those in MacBooks, possess a designated “cycle count.” This term refers to the finite number of times the battery can discharge from 100 percent to zero. Each instance of plugging in the charger and connecting it to the Mac contributes to an increment in the cycle count.

Before delving further into this topic, it is important to be aware of the cycle limit for your specific computer. 

  • Most MacBook models, including MacBook Air and MacBook Pro versions manufactured after 2009-2010, have a maximum cycle count of 1000. On the other hand, older Macs typically have cycle limits ranging between 300 and 500.

As you approach your maximum cycle count, it becomes increasingly likely to encounter a Service Battery warning. Fortunately, macOS provides a means to monitor your cycle count, offering insights into your battery’s usage.

There are a couple of methods to accomplish this:

  • By clicking on the Apple menu logo located in the Toolbar and holding the Option key, you can then select the “System Information” menu item.
  • Alternatively, you can use Spotlight to search for “System Information.”

Once the System Information window opens, navigate to the Hardware section in the left-hand menu tree and select the Power screen.

Here, you will find comprehensive information regarding your battery. In the Health Information section, you can observe your cycle count.

If the cycle count displayed exceeds the number specified on Apple’s support page, it explains the occurrence of the Service Battery warning. However, if the screen indicates “Normal,” there is no cause for concern.

Similarly, the “Replace Soon” message should not be an immediate worry; it merely serves as an indication that you should consider replacing the battery in the near future. In some cases, you may encounter a “Replace Now or Service Battery” warning, even if the cycle count is low. In the next section, we will explore several methods to address this warning.

3 Ways to Fix the Service Battery Warning on Mac

There are various factors that can contribute to a failing battery, but only a select few solutions are proven to be effective. Let’s explore three of these solutions:

Reset the System Management Controller (SMC):

If you own a MacBook with a non-removable battery, attempting an SMC reset can be worthwhile. Mac models released from 2009 onwards fall into this category, and if your battery is failing on such an older machine, it might be a good idea to consider investing in a new MacBook altogether.

To reset the SMC, follow these steps:

  • Begin by shutting down your MacBook.
  • Connect the power adapter to a power outlet and then connect it to your computer.
  • Press and hold the Shift + Control + Option + Power buttons all at the same time.
  • After holding the buttons, release them.
  • Power up your MacBook as usual.
  • Check the battery status menu to see if the “Service Battery” warning has vanished.

Resetting the SMC often proves to be effective. However, it’s important to note that resolving the Service Battery warning may require additional measures beyond an SMC reset. It’s worth mentioning that resetting the SMC can also help address Wi-Fi issues and dropped connections on your Mac.

Battery Re-calibration Technique

If you’re encountering the Service Battery notification on your Mac, there’s a method you can employ to rectify it. This approach, although time-consuming, proves to be worthwhile in resolving the issue. Notably, even Apple suggests this technique to enhance battery care, with the frequency of implementation dependent on your computer usage patterns.

Follow the steps below to proceed with battery recalibration:

  • Begin by charging your battery to its maximum capacity of 100 percent.
  • Once fully charged, keep your MacBook/Pro/Air connected to the charger and powered on for approximately two hours.
  • Subsequently, unplug the charger and utilize your Mac until it completely depletes its battery power. You’ll observe a low battery warning in the “Battery Status” menu, and the Mac will eventually enter sleep mode without prior notification. When this occurs, power off the device.
  • Allow a minimum of five hours to elapse, ensuring ample time for the system to rest.
  • After the waiting period, proceed to charge your Mac until it reaches its full capacity.

By adhering to these instructions, you should successfully recalibrate your battery. It’s important to note, however, that this solution may not yield the desired outcome. If that’s the case, there is one final alternative to consider, even though it might not align with your initial expectations.

Visit an Authorized Apple Repair Center

If you’ve exhausted all possible remedies to resolve the Service Battery notification on your Mac without success, your next course of action would be to seek assistance from a certified Apple service provider.

The warning message could have resulted from several factors, such as a defective battery, complications with peripheral devices that rely on your Mac for charging, among others. When basic troubleshooting methods have failed, an Apple Genius Bar technician is often best positioned to identify the underlying issue.

However, bear in mind that the warning may have surfaced due to a legitimate battery problem that requires replacement. In such cases, the cost of a new battery may be significant, running into the triple digits. Therefore, if you decide to pursue a repair service, it’s prudent to factor in the cost of a replacement battery as part of your future plans.


Is it necessary to fully charge my MacBook battery every time?

No, it is not necessary, and understanding this can actually help prolong the overall lifespan of your battery. It is recommended to regularly disconnect your laptop from the power source and allow the battery level to drop below 50% in order to maximize its longevity. Each time the battery level falls below 50% and then recharges, it is considered a cycle, and this is perfectly fine. The primary objective is to extend the battery’s lifespan rather than being overly concerned about the cycle counts.

Is it possible to replace a MacBook laptop battery on my own?

While it may seem tempting to save costs by installing a new MacBook battery yourself, it’s important to note that the expense not only includes the price of the battery itself, which can be around $100, but also the labor involved. This is where the overall cost increases when relying on Apple’s services.

Consequences of disregarding service battery warnings

It is crucial not to overlook the battery service warnings on your device. Ignoring these warnings could potentially result in hardware damage to your computer. Moreover, it presents a safety risk, particularly if the battery starts to swell and affects the integrity of the laptop’s aluminum structure. While the likelihood of fires is relatively small, it is a possibility that should not be taken lightly when you are aware that your battery requires replacement.
