You are probably wondering if it is time to book your mac battery replacement. After all, your Mac may be struggling to keep up with your busy lifestyle. And while there are many factors that can affect how long your MacBook battery will last, poor performance could be the result of a weak battery.
If you’re not sure if it’s time for a new battery, take these five steps to help you decide:
1) Use the Battery Health indicator in System Preferences to monitor your battery’s health. The indicator will show you how much power is remaining and whether or not the battery is at its peak performance.
2) If you notice a significant drop in performance after using your Mac for an extended period of time, it might be time to replace your battery. Restore Yosemite or later on an older Mac with this unofficial backup/restore utility from developer Marco Arment:
3) Consider the type of use that your MacBook tends to get during its lifetime. A lithium-ion polymer (LIP) battery will last longer when used less frequently, whereas a lithium-ion (LiFePO4) battery will last longer when used more frequently. So consider how often you use your MacBook and what type of work you do when assessing which type of MacBook battery would be better for you.
