If your MacBook battery needs replacing, you often get the question: an original or a compatible battery? An original Apple battery is the first choice for many people, but there are also good compatible batteries from other makers, and bad ones. This article explains the difference, which messages you may see in macOS and what to look for in a battery replacement.
Blue Apple replaces MacBook batteries in Amsterdam and tells you beforehand which type of battery we fit.
What is an original battery?
An original battery is made for or by Apple, with the same cells and the same management chip as the battery in your MacBook. Apple supplies them through its own repair channels. They are the most expensive, but you know for sure that capacity, safety and communication with macOS are right.
What is a compatible battery?
A compatible battery is made by another manufacturer to fit your model. Quality varies widely:
- Good compatible batteries use solid cells, have the stated capacity and a good protection chip.
- Bad compatible batteries have less capacity than the label says, wear quickly or have weak protection. Avoid those.
What to look for
- Capacity: does the stated capacity (in mAh or Wh) match the original?
- Protection: against overcharging, short circuits and overheating.
- Origin and certification: a known supplier and a CE mark.
- Aftercare: what happens if the battery gives problems within a short time?
- Fitting: on many MacBooks the battery is glued in. Fitting it well without damaging other parts matters as much as the battery itself.
Messages in macOS
macOS reads data from the battery, such as capacity and cycle count. On some models and macOS versions the Mac indicates that a battery has been fitted that it does not recognise as original, or shows battery health differently. The battery then usually works normally. After a replacement, check System Settings, Battery and System Information, Power. See checking battery health and cycles.
Lifespan
A good battery, original or compatible, lasts years with normal use. Exactly how long also depends on how you use it: heat and often running it completely flat shorten its life. See saving your MacBook battery.
When to choose which?
- A recent MacBook you want to use for a long time: an original battery or a high-quality compatible one.
- An older MacBook for which no original battery is available: a good compatible battery is often the only option.
- Budget matters: a good compatible battery can be a fine choice, but do not pick the cheapest with no known origin.
A swollen battery
Whatever the type: a battery that swells must be replaced immediately. Signs are a bulging bottom, a stiff trackpad or a lid that does not close properly. See swollen battery.
Replacing it yourself?
On many MacBooks the battery is held by strong adhesive strips. Pulling it out without solvent or with a metal wedge can damage the battery, and a damaged lithium battery can catch fire. See repairing it yourself with a kit.
What we do at Blue Apple in Amsterdam
We first test whether the battery really is the problem, tell you which battery we fit and what it costs, and check capacity and charging after the replacement. More on our page about MacBook battery replacement.
Frequently asked questions
Is a compatible battery dangerous?
A good one is not. A cheap one with no known origin or certification can carry risks.
Does a compatible battery work with macOS updates?
Yes, the battery keeps working. At most macOS shows a message or less information.
Can I have an original fitted later?
Yes, a battery can always be replaced again.
