What causes a MacBook battery fault?
Batteries in all devices have a shelf life. We usually see battery issues in devices from around 2 years old onwards. They only have so many charging cycles before you will notice a difference in its performance.

Some updates have been blamed for excessive power usage so we would recommend checking online for any software related issues that may be causing the fault before booking in a repair.

Using 3rd party charging cables and adapters can also cause problems with batteries.

How do we repair a MacBook battery?
The first thing we do before any repair is check the fault. We will then proceed to replace the battery. We only ever use original batteries as some 3rd party batteries can cause problems.

The MacBook then gets put through to our test bench where its charge and durability is tested before releasing it for dispatch.
