MacBook batteries wear out after several hundred charge cycles. When macOS shows “Service Recommended”, the battery runs down in an hour or two, or the trackpad starts to lift, it is time for a new one. Most MacBook battery replacements are done the same day.
When to replace the battery
- macOS shows “Service Recommended” under Battery settings
- The Mac shuts down suddenly at 20 or 30%
- Battery life is a fraction of what it was
- The trackpad is stiff or won’t click, or the case is bulging (a swollen battery: stop using it)
- The Mac only runs when plugged in
We fit a new battery, calibrate it and check the charging circuit and MagSafe or USB-C port at the same time. Your files and settings are not affected.
We diagnose the fault on the bench and agree the price with you before any work starts. Many repairs are finished the same day when parts are in stock, and all come with a 3-month warranty.
Questions we get asked
How do I check my battery’s health?
Choose Apple menu > System Settings > Battery, then click the (i) next to Battery Health. It shows the maximum capacity and whether service is recommended.
Is a swollen battery dangerous?
It can be. A swollen lithium battery can crack the case and, rarely, catch fire. Switch the Mac off, don’t charge it, and bring it in.
