When should the battery be replaced in a MacBook?
Based on our experience, the lifespan of batteries shows quite a wide variation. There are cases where the battery has over 800 charge cycles and still works well, and there are also cases where it’s already failed with only 100-200 charge cycles recorded. This largely depends on how the device is used.
If your MacBook displays a message to replace the battery, and/or the battery life is very short without being plugged in, or if it has swollen, the battery needs to be replaced.
Laptops, including MacBooks, are not designed to run constantly plugged in, just as they are not meant to sit in a drawer for three years. If we use them as desktop replacements with a monitor, mouse, etc., and they are constantly plugged in, at least make sure to enable the optimized battery charging feature in the settings.
Regarding the repair:
Immediate repair is required if our device swells. This is always due to the battery, meaning the battery has failed, swollen, and is causing the MacBook to bulge.
In this case, do not charge the device anymore and take it to a service center, because otherwise, it will completely damage the device. It’s important to note that motherboard issues can also cause symptoms that might make us suspect only the battery is the problem (such as random shutdowns, slow charging, fast battery drain, or working only when plugged in). In this case, unfortunately, a battery replacement might not be enough, but motherboard issues occur in a small percentage of cases. Generally, we can say that when the battery capacity drops to around 80%, the user will start noticing something is wrong with the device. From that point, a battery replacement can help restore usability.
As with screen replacements, the most important factor in battery replacements is sourcing the right parts. There are many manufacturers with subpar batteries on the market. Our job is to purchase and install the best quality parts currently available, to spare our customers the hassle. We have the necessary experience and network to ensure this.
