与其他笔记本电脑相比，MacBook 以更长的电池寿命着称(MacBooks are known for their longer battery life)。即使每天大量使用，您也可以在Mac上工作数小时，而不必担心电池耗尽。
然而，即使是最好的技术也会随着时间的推移而失去性能。随着Mac的老化，您会发现需要更频繁地为其充电。对于某些人来说，必须一直靠近充电器并不是问题，但其他人可能会觉得这更困难。更不用说在重要任务或在线会议中 让您的Mac意外死机有多烦人。(Mac)
如果您使用Mac已经有一段时间了，并且担心电池已经耗尽，那么有一种方法可以判断是否需要更换Mac Book 的电池。
您的 Mac 需要新电池吗？ (Does Your Mac Need a New Battery? )
在您决定更换 MacBook 的电池之前，请注意以下几点。
你的 Mac 一直在死去(Your Mac Keeps Dying)
您的Mac(Mac)需要新电池的第一个（也是最明显的）迹象是，即使您不久前为它充电，您的(you charged it up)计算机仍然会死机。(computer keeps dying)首次购买Mac时，一次充电即可在其上工作、观看视频和玩游戏数小时。
如果您现在似乎经常需要寻找充电器来保持Mac正常工作，那么您的计算机很可能需要更换新电池。
您的 Mac 过热(Your Mac Is Overheating)
Mac 过热的(your Mac is overheating)原因可能有很多。有时这只是日常使用的结果。但有时过热可能表明您的 Mac 电池有故障，您需要尽快更换Macbook电池。
您收到维修电池警告(You Get a Service Battery Warning)
Mac 电池需要更换的最糟糕也是最可靠的迹象是，如果您收到维修电池警告。如果您在通常会在屏幕右上角看到百分比数字的下拉菜单中收到警告，则表示您的电池(extending your battery)寿命没有延长，是时候换一个新的了。
如何检查电池的状况 (How To Check Your Battery’s Condition )
即使您还没有收到电池服务警告，也值得在为时已晚之前检查您的电池状况。您的Mac有一个实用程序，可以帮助您更好地了解电池何时耗尽。
要检查 MacBook 的电池状况，请单击菜单栏中的电池图标(battery icon)（屏幕右上角的百分比图标）。如果显示Condition: Normal，则表示一切正常，无需担心电池问题。
但是，如果您收到以下消息之一，则意味着您的电池不再像新电池一样好，是时候开始寻找更换选项了。
您的 Mac 电池运行正常，但电量低于新电池时的电量。
电池工作正常，但比新电池时的电量要少得多。您可以继续使用电池，直到您更换 MacBook 的电池，而不会损坏您的电脑。
- 服务电池。 (Service Battery. )
电池无法正常工作，您可能会或可能不会注意到其行为或所持有的电量发生变化。将您的计算机送去维修。在检查电池之前，您可以继续使用电池，而不会损坏您的计算机。
除非您收到服务电池(Service Battery)警告，否则您的计算机不会面临迫在眉睫的危险。此外，Replace Soon状态意味着您的电池仍将持续一段时间，然后您必须更换它。
“很快”到底有多远？ (How Far Is “Soon” Exactly? )
如果您的电池状况显示除Normal以外的任何内容，则无需惊慌，而是检查当前的循环计数。循环(Cycle)计数是指您用完所有 Mac 电池然后将其完全充电的次数。
根据Apple的说法，现代 Macbook 的电池在开始老化之前可以持续使用 1000 次循环。经过这 1000 次循环后，您的电池可保留高达 80% 的原始电量。
这意味着您可以继续安全地使用电池超过 1000 次循环，它只会逐渐失去电量。您可以使用 Mac 的系统信息(System Information)工具来找出您的计算机处于的确切周期数。
如何检查您当前的周期计数(How To Check Your Current Cycle Count)
- 单击屏幕左上角的 Apple 菜单。(Apple menu)
- 按住选项 (Alt)(Option (Alt))键。
- 从下拉菜单顶部 选择系统信息。(System Information)
- 在左侧菜单中，在Hardware下，选择Power。
- 然后查找Battery Information > Health Information > Cycle Count。旁边的数字将是您Mac的当前循环计数。
在我当前的循环计数为 1482 时，我的电池处于“尽快更换(Replace Soon)”状态。这仍然让我有时间弄清楚我是要更换电池还是以后再买一台新的MacBook。
是时候更换 MacBook 的电池了吗？(Is It Time To Replace Your MacBook’s Battery?)
一开始，更换Mac Book 的电池似乎并不重要。然而，一块好的电池是让您的Mac便携并确保其最佳性能的原因。
在某些情况下，可能值得考虑完全更换您的Mac。然而，一块新电池可以起到很长的作用，并为您节省一笔可观的钱。如果您暂时还没有准备好花钱，请查看我们的教程，了解如何在不更换 Mac 的情况下延长电池寿命。(extend the battery life on Mac)

How To Tell If It’s Time To Replace Your MacBook’s Battery
Compared to other laptopѕ, MacBooks are known for their longer battery life. Even with extensive daily use, you can work on a Mac for hours without worrying about your battery dying.
However, even the best tech loses performance over time. As your Mac ages, you’ll notice the need to charge it more often. For some people, having to be next to a charger all the time isn’t a problem, but others might find it more difficult. Not to mention how annoying it can be having your Mac unexpectedly die on you in the middle of an important task or an online meeting.
If you’ve been using your Mac for a while and are worried that your battery’s worn out, there is a way to tell whether it’s time to replace your MacBook’s battery.
Does Your Mac Need a New Battery?
Before you decide to replace your MacBook’s battery, here are a few things that you should pay attention to.
Your Mac Keeps Dying
The first (and the most obvious) sign that your Mac needs a new battery is when your computer keeps dying even though you charged it up not so long ago. When you first bought your Mac, you could spend hours on it working, watching videos, and playing games on a single charge.
If it seems like you now constantly have to look for a charger to keep your Mac working, there’s a good chance your computer needs a new battery.
Your Mac Is Overheating
There can be many reasons why your Mac is overheating. Sometimes it’s just the result of daily use. But sometimes overheating might be a sign that your Mac’s battery is faulty and you need to replace your Macbook battery soon.
You Get a Service Battery Warning
The worst and also the most reliable sign that your Mac’s battery needs replacing is if you get a service battery warning. If you get a warning in the drop-down menu where you normally see the percentage number in the top right corner of your screen, it means there’s no extending your battery life and it’s time to get a new one.
How To Check Your Battery’s Condition
Even if you haven’t got the battery service warning yet, it’s worth checking your battery condition before it’s too late. Your Mac has a utility that can help you understand better when you can expect your battery to die.
To check your MacBook’s battery condition, click on the battery icon in the menu bar (the percentage icon in the upper right corner of your screen). If it says Condition: Normal, that means everything is functioning normally and there’s no need to worry about your battery.
However, if you get one of the following messages, it means your battery isn’t as good as new anymore and it’s time to start looking into replacement options.
Your Mac’s battery is functioning normally but holds less charge than it did when it was new.
The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace your MacBook’s battery without harming your computer.
The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Take your computer in for service. You can continue to use your battery before it’s checked without harming your computer.
Unless you get the Service Battery warning, your computer is in no imminent danger. Moreover, Replace Soon status means your battery will still last you a while before you’ll have to replace it.
How Far Is “Soon” Exactly?
If your battery condition says anything other than Normal, it’s no reason to panic but check the current cycle count instead. Cycle count means the number of times you use up all of your Mac’s battery and then fully recharge it.
According to Apple, the modern-day Macbook’s battery can last through 1000 cycles before it starts aging. Past those 1000 cycles, your battery is designed to retain up to 80% of its original power.
That means you can continue safely using your battery past 1000 cycles, it will just gradually lose its power. You can use Your Mac’s System Information tool to find out the exact number of cycles that your computer is at.
How To Check Your Current Cycle Count
- Click on the Apple menu in the upper-left corner of the screen.
- Hold down the Option (Alt) key.
- Select System Information from the top of the drop-down menu.
- From the left side menu, under Hardware, select Power.
- Then look for Battery Information > Health Information > Cycle Count. The number next to it will be the current cycle count of your Mac.
At my current cycle count of 1482, my battery is in the Replace Soon condition. That still gives me time to figure out whether I want to replace my battery or get a new MacBook later.
Is It Time To Replace Your MacBook’s Battery?
