How do I know if my MacBook battery needs to be replaced?

Macbook with battery thats needs replacing

If you heavily rely on your laptop for work, writing endless essays or streaming YouTube videos, then you’ll understand the importance of a working battery that keeps up with your busy lifestyle. As with many tech products, your MacBook battery won’t last forever. There are, however, some things you can do to ensure your laptop doesn’t shut down mind-use.

As your laptop ages, be sure to watch out for the signs of a worn-out battery. If you find your once nimble MacBook struggling to hold a charge, suddenly shutting down with plenty of power left, or showing the dreaded “Service Battery” warning, then it may be time for a replacement battery.

So, if you’re ready to make your work life easier and wave goodbye to your battery struggles, keep reading or get in touch for first-class tech support.

What is good battery health for MacBook?

A healthy Mac laptop battery should last several hours when doing general admin jobs and at least two hours when playing games or editing media. The age and model of your laptop will also affect the longevity of its battery.

If you want to get technical, you can check the health of your MacBook’s battery in the system settings on your laptop. Simply head to the Apple menu, then “About This Mac”, “System Report”, and “Power”. This is where all of the information about your MacBook battery is stored.

The maximum capacity is a good indication of how well your laptop battery is functioning. If your battery capacity is between 90% and 100%, then your laptop battery is in pretty good condition. Anything below that, and you may start to notice your laptop slows down.

Simply put, once your battery starts to last below half the time it used to on a full charge, it’s time to start thinking about replacing it.

What is a battery cycle count?

A battery charge cycle is one full use of a battery’s power. This could be one single use that takes it from 100% to 0% or a few uses, such as 100% down to 20%, charged up to 100%, then used another 20%.

This may sound daunting, but you shouldn’t be worried about your charge cycles adding up, as the laptop is designed to be used. Plus, with our fast and affordable battery replacement services, we can ensure your MacBook lives on for many years.

How long should I expect a new battery to last?

Various elements affect the longevity of your MacBook’s battery life, including the type of model you have, how you use the device and how you care for it. Typically, a new MacBook laptop battery should last a good 2/3 years, at the very least, even with heavy use.

Some Macs, if well looked after, can go on for many years past that.

How can I prolong the life of my MacBook battery?

There are a handful of ways you can extend the life of your MacBook battery before turning to a replacement.

  • Charge your Mac as soon as it gets to 20% and allow it to charge up to 100% without unplugging.
  • Leave your MacBook plugged in for an hour or so when it’s reading 100%.
  • Turn off features you don’t use and optimise your screen brightness.
  • Avoid charging your laptop in extreme temperatures, such as in direct sunlight or a hot car.
  • Try not to charge your battery in short bursts when it’s low (for example, if it’s at 4% and you charge it to 30%, then unplug it). Regularly doing these low percentage short burst top-ups will quickly ruin the battery.

While these tips can help preserve the battery life and keep your laptop running longer, it still won’t last forever. If you notice your MacBook slowing down or shutting off randomly, this can indicate an issue with the battery’s health, and it may be time to replace it.

How do I check the battery health on my MacBook?

The best way to check your battery health is to check how many charge cycles the MacBook currently has. This can be seen inside the “System Report” under the “Power” section (as previously mentioned).

A good rule of thumb is that batteries with over 1000 cycle counts should be replaced even if the “Battery Condition” reads “Normal”. If the condition reads “Service Recommended”, it’ll need changing even if the current cycle count is less than 1000.

Will I get a service battery warning on a MacBook?

Most of the time, if your MacBook’s battery life is starting to dwindle, the computer will tell you on the drop-down menu when you click the battery icon. However, it is possible you could need a battery replacement without the system telling you about it.

If you’ve noticed the battery power holding significantly less charge or the casing looks like it may be warping due to battery swelling, it’s worth getting it checked by a professional like Hero Support.

What happens if I don’t replace my MacBook battery?

Eventually, all MacBook batteries will be completely unable to hold power. At this point, your MacBook will switch off the second you remove the power cable and may experience unexpected shutdowns, losing any unsaved work and forcing a full system restart each time.

This can also cause file corruption and Operating System corruption. If you have a newer MacBook Pro or other Mac model, you may have a MagSafe magnetic charger, which is extremely easy to remove accidentally.

Is it better to replace the battery or buy a new MacBook?

Replacing the battery in a MacBook is almost always cheaper than buying a MacBook of the same age and specs secondhand and significantly cheaper than buying a brand-new Mac straight from the Apple store.

The life of a laptop can significantly outrun the life of its battery. So, while there are some benefits to having a shiny new MacBook, you have to remember that the battery life will only last so long in that one, too.

Ultimately, replacing the battery is not only more environmentally friendly, but it is also more financially viable.
