笔记本电脑电池是昂贵的设备，所以如果你有一台仍然可以正常工作的旧笔记本电脑，谁愿意花 100 美元以上来更换电池(battery right)！幸运的是，人们想出了很多方法来恢复笔记本电脑上的电池，有些是技术性的，有些是有趣的，有些是奇怪的。
在本文中，我将尝试列出我读过的所有不同的内容，如果我记得我在哪里读过它，我将链接回原始来源。如果您尝试自己恢复笔记本电脑电池，请在评论中告诉我们您的方法。
方法 1 – 冷冻法
曾经看过一个电影，男的手机(’ phone)快没电了，他把电池拿出来卡(battery and stuck)在了雪里，明显延长了续航！我仍然不知道这是否属实，但显然你可以冻结笔记本电脑电池并从中获取更多汁液。这是非常简洁的过程：
第 1 步(Step 1)：取出电池并将其放入密封的Ziploc 或塑料袋中(Ziploc or plastic bag)。
第 2 步(Step 2)：继续将袋子放入冰箱并放置约 12 小时。有人建议放置更长时间，但我不会放置超过 24 小时。
第 3 步(Step 3)：取出后，取下塑料袋(plastic bag)，让电池升温至 室温(room temperature)。一定要用毛巾把它包起来，并在它升温时擦去任何冷凝水。
第 4 步(Step 4)：重新插入笔记本电脑电池并(battery and charge)完全充电。
第 5 步(Step 5)：充电后，拔下电源，让电池电量(battery drain)完全耗尽。
现在重复步骤 4 和 5 至少 4 次：一直充满电，然后完全放电。应该是这样！除非您的电池漏酸，否则您的电池寿命(battery life)应该会有所增加。
请注意，您只能在NiCD 或 NiMH 电池(NiCD or NiMH batteries)上执行此操作。如果你在锂电池(lithium battery)上尝试这个，它会使电池寿命变差(battery life worse)。不幸的是，没有办法恢复锂电池(lithium battery)。你必须找到你的笔记本电脑规格，看看你有什么样的电池。对于锂离子电池，您无法恢复(t restore)，但您可以延长电池的使用寿命。阅读(Read)方法2。
方法 2 – 冷却您的计算机
如果您有锂离子(lithium ion)电池，则可以通过确保笔记本电脑凉爽来延长其使用寿命。如果您的笔记本电脑非常热，可能会损坏电池并导致电池寿命(battery life)缩短。我有一台旧的Sony VAIO 笔记本电脑(Sony VAIO laptop)，当我从亚马逊(Amazon)购买笔记本电脑散热垫时，我发现笔记本电脑的(cooling pad)电池寿命(battery life)显着增加。你可以花20 美元买到这样的一个。(this)
您可能认为您的电池已经到了最后一站，但这可能只是因为它变得太热了，因此更快地失去了电量。
方法 3 – 重新校准您的电池
对于大多数较新的电池，这不再是必需的，但如果您的电池快要耗尽了，那么它可能是一个相当旧的电池。在这种情况下，您可能会从重新校准中受益。重新校准电池是因为有时操作系统(operating system)无法计算出电池中剩余的容量。如果笔记本电脑始终插入电源或电池从未完全耗尽，则可能会发生这种情况。
如果您的电池从未充电到 100%（例如仅充电到 95%），或者操作系统说您有 35 分钟的电池剩余时间(battery remaining)，但计算机迟早会死机，您可以判断您的电池是否需要校准。很多厂商已经发布了针对特定笔记本型号的校准工具，所以首先用你的电脑型号(computer model)+电池校准进行(battery calibration)谷歌搜索(Google search)。这是 Sony 的一个示例(Sony)工具(example tool)。
如果您必须手动重新校准电池，该过程非常简单：
第 1 步(Step 1)：将电池充电至 100% 或任何可以达到的最大百分比，然后将其放置约 2 小时以冷却。
第 2 步(Step 2)：现在断开电源，让电池耗尽(battery drain)。关于如何做到这一点似乎有两种观点。您可以让电池一直耗尽直到笔记本电脑死机，或者您可以将其设置为进入睡眠或休眠状态大约 3% 到 5%。无论哪种方式，您都希望确保显示屏一直亮着，直到它死机或进入睡眠状态。
第 3 步(Step 3)：让计算机保持关闭状态 3 到 5 小时。
第 4 步(Step 4)：重新打开并让它一直充电到 100%。
差不多就是这样。现在计算机应该可以更准确地读取电池的实际容量。
方法 4 –(Method 4) 插入(Plugged)时取出电池(– Remove Battery)
如果您的笔记本电脑带有可拆卸电池，则可以在将电池插入墙壁时尝试将其取出。您可能需要对此进行测试，因为某些笔记本电脑在取出电池后无法正常工作。(t work)但是，如果笔记本电脑运行良好并且一直连接到电源(power source)，则只需卸下电池可能会有所帮助。
无论是否在笔记本电脑中，电池(battery regardless)中都会继续发生化学反应，但它可以延长电池的使用寿命。由于插入时电池是凉爽的而不是热的，因此您将获得更长的电池寿命。
当然，您需要确保您没有生活在断电的区域，因为您的计算机会立即死机并且您会丢失任何数据。这种方法既费时又烦人，而且大多数人都不会这样做。下面的最后一种方法(method below)可能是最好的。
方法 5 – 在充满电的情况下拔下插头
您可以尝试的最后一个选项是让电池充电(battery charge)到 100%，然后简单地拔下计算机。当它接近死亡，即低于 5% 时，继续将其插入并让它充电。但是，这可能会缩短较新的锂离子电池的(lithium ion)电池寿命(battery life)，因此对于这些电池，建议您只让电池电量降至(battery level drop)35% 至 45%，然后再将其充电至 75% 至 85%。听起来(Sounds)很疯狂，但显然这会给你最好的电池寿命(battery life)，因为它不会用完那么多的充电和充电周期(charge and recharge cycles)。
同样，这种方法也需要一些工作，但如果你真的想增加电池寿命(battery life)，值得一试。您是否使用了此处未提及的任何其他方法来延长笔记本电脑的电池寿命(battery life)？如果是这样，请在评论中告诉我们。享受！
How to Restore a Dead or Dying Laptop Battery
Lаptop batteries are expensive pieces of equipment, so if you have an old laptop that still works fine, who wants to shell out upwаrds оf $100 to replace the battery right!? Luckily, there are a lot of ways, some teсhnical, some interesting and some strange ones, that pеople have come υp with to restore dying batteries on laptops.
In this article, I’m going to try to list out all the different ones I’ve read about and if I can remember where I read it, I’ll link back to the original source. If you have tried to restore a laptop battery yourself, let us know your method in the comments.
Method 1 – The Freezing Method
I once saw a movie where a guys’ phone was about to die, so he took out the battery and stuck in some snow, which apparently made it last longer! I still don’t know if that’s true or not, but apparently you can freeze a laptop battery and get more juice out of it. Here’s the procedure very succinctly:
Step 1: Take your battery out and place it in a sealed Ziploc or plastic bag.
Step 2: Go ahead and put the bag into your freezer and leave it there for about 12 hours. Some people suggest leaving it for longer, but I wouldn’t leave it for more than 24 hours.
Step 3: Once you take it out, remove the plastic bag and let the battery warm up until it reaches room temperature. Be sure to wrap it in a towel and wipe away any condensation as it warms up.
Step 4: Reinsert the laptop battery and charge it completely.
Step 5: Once charged, unplug the power and let the battery drain all the way down.
Now repeat steps 4 and 5 at least 4 times: charge all the way to full, then discharge completely. That should be it! Unless your battery is leaking acid, you should get some kind of bump in the battery life.
Note that you should only perform this on NiCD or NiMH batteries. If you try this on a lithium battery, it’ll make the battery life worse. Unfortunately, there is no way to restore a lithium battery. You’ll have to find your laptop specs to see what kind of battery you have. For lithium ion batteries, you can’t restore, but you can possibly extend the life of a battery. Read method 2.
Method 2 – Cool Your Computer
If you have a lithium ion based battery, you can increase it’s life by making sure your laptop is cool. If you have a laptop that gets really hot, it can damage the battery and cause the shortness in battery life. I have an old Sony VAIO laptop and I saw a significant increase in laptop battery life when I bought a laptop cooling pad off Amazon. You can get one like this for $20.
You may think your battery is on it’s last leg, but it could simply be that it’s getting too warm and therefore loses charge faster.
Method 3 – Recalibrate Your Battery
With most newer batteries, this is no longer necessary, but if your battery is dying, then it’s probably a pretty old battery. In that case, you may benefit from a recalibration. Recalibrating a battery is done because sometimes the operating system cannot figure out how much capacity is left in the battery. This can happen if the laptop is always plugged in or if the battery was never let to die all the way.
You can tell whether your battery needs calibration if your battery never charges to 100% (say only to 95%) or if the OS says you have 35 min of battery remaining, but the computer dies either much sooner or much later. A lot of manufacturers have released calibration tools for specific laptop models, so first perform a Google search with your computer model + battery calibration. Here’s an example tool from Sony.
If you have to manually recalibrate a battery, the procedure is pretty straight-forward:
Step 1: Charge your battery to 100% or to whatever max percentage it can reach and leave it there for about 2 hours to cool down.
Step 2: Now disconnect the power and let the battery drain. There seems to be two views about how to do this. You can either let the battery run down all the way until the laptop dies or you can set it so that it goes to sleep or hibernates around 3 to 5%. Either way, you want to make sure the display stays on until it either dies or goes to sleep.
Step 3: Let the computer remain turned off for anywhere between 3 to 5 hours.
Step 4: Turn it back on and let it charge all the way to 100%.
That’s pretty much it. Now the computer should be giving you a more accurate reading of the actual capacity of the battery.
Method 4 – Remove Battery When Plugged In
If you have a laptop with a removable battery, you can try to remove the battery during the times you have it plugged into the wall. You may have to test this because some laptops don’t work properly with the battery removed. However, if the laptop is running fine and it’s connected to a power source all the time, it may help to simply remove the battery.
The chemical reactions will continue to occur in the battery regardless of whether or not it’s in the laptop, but it could increase the life of the battery. Since the battery is cool and not hot when plugged in, you’ll get more life out of your battery.
Of course, you’ll need to make sure you’re not living in an area where the power goes out because your computer will die immediately and you’ll lose any data. This method is also time-consuming and annoying and something most people won’t do. The last method below may be the best.
Method 5 – Unplug at Full Battery
The last option you can try is to let the battery charge to 100% and then simply unplug the computer. When it gets close to dying, i.e. less than 5%, go ahead and plug it in and let it charge up. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. Sounds crazy, but apparently that will give you the best battery life because it won’t use up as many charge and recharge cycles.
Again, this method also requires a bit of work, but it’s worth a try if you really want to increase your battery life. Have you used any other methods not mentioned here to increase your laptop battery life? If so, let us know in the comments. Enjoy!
