1. Macbook doesn’t work unless it is plugged in – If your computer has to be constantly plugged in for it to work, you can’t enjoy the portability that comes with having such a machine. Hence, if you cannot get any work out of your computer without having to connect it to a power source, your batteries have become dysfunctional. It is time to replace them.
2. Macbook shuts down randomly with a healthy battery percentage – If your battery is not working properly, it might display false percentage numbers on the screen or even discharge suddenly when you’re working while disconnected from a power supply
3. Macbook does not turn on until it is fully charged – This issue is actually very commonly experienced when the battery has been used extensively over a long period of time. In such cases, a replacement is the only viable solution
4. Less usage between charges – If your usage is decreasing between charges, you might have to replace your battery at some point. This is because all batteries lose their efficiency over time and the more you wait for a replacement, the more you worsen your usage experience
