macbook pro battery swells and disappears again

Hello, I suggest you opt for the warranty.

You can benefit from the guarantee. Under normal circumstances, Apple can replace the battery for machines free of charge within one year of purchase. Some people reported that machines within 3 years can also be replaced. free.

Second, the best way to extend the life of the lithium battery used in MacBook and other devices is to charge and discharge the battery regularly, at least once or twice a month for a complete charging and discharging process, and not for a long time. The battery power is too low or too high, to ensure that the battery is always at its highest activity.

The MacBook can only be used for 2 hours after charging!

Because the built-in power supply of Apple Mac computers uses Li-ion batteriesthium, and lithium batteries in Mac computers are equipped with self-protection, called low temperature protection.

This means that when the temperature is too low, the lithium metal in the battery will settle and no longer react chemically with the material, resulting in an internal short circuit in the battery.

Therefore, during the cold winter and too cold environment, users' Mac computers will not be able to charge.

How to fix Apple Mac not charging in winter

Actually, after knowing the reason why Mac cannot be charged, our solution is very simple. It's nothing more. to make our Mac “Hot”.

First of all, the optimal temperature for chemical reactions in the best lithium batteries when charging is above 10°C, so it is better to charge in a warm room, otherwise the batterycould be easily damaged.

So if users find that their Mac cannot be charged, they can first move the device to a warm room to charge it, i.e. slightly warm the Mac before charging it. (It can also be heated with a hair dryer...)

Secondly, if you find that your Mac still cannot be charged when it is hot, you need to see if there is a problem with the Mac. charger. The solution is to heat the charger as well. If you ask me how to cover the heat, there are "masters" on the Internet who use a quilt to cover it...

Finally, if users think it is stupid to use a quilt or hair dryer to heat the device, some users will directly use their Mac to watch videos for a while or run a heating program for a while. some time. Come warm upyour mac and recharge it.

MacBook Pro 13 inch battery maintenance

The problem is not serious, you can solve it like this

1. After the battery is fully charged, unplug the power source and use it until it automatically turns off when there is no power

2. Repeat 3 to 5 times, which corresponds to discharge-charge-discharge. . .

This should be much better. Now the batteries are all lithium batteries, so it's not a big problem.

How long does it take Apple to replace the battery after-market?

The poster asks about the maintenance method of lithium batteries.

There are three points for the maintenance of lithium batteries

< p>1.CannotOvercharge, overcharge will damage the lithium battery. (Usually when you plug in the power cord, the laptop will handle it for you. If it is plein, the laptop will automatically prevent battery overcharging.) Of course, the best lithium battery. Maintenance involves charging 80% of the electricity and then leaving it. This is generally the case for lithium batteries sold in stores. They will initially be 80% charged, so you can use them as soon as you receive them. for lithium batteries in use. Not suitable.

2. Do not over-discharge, because over-discharging will greatly damage the lithium battery (for example, if you wait for a very long time without charging, the energy of the lithium battery will be exhausted directly. As a result, the computer battery laptop cannot be charged. If you search on Baidu you will see many miserable examples of over-discharged laptop batteries.) The lithium battery itself will do this. self-discharge. A good lithium battery will also break sIf it is not charged for a long time, it is because the electricity has been discharged or over-discharged.

3. Lithium batteries have a certain charge-discharge lifespan. Charge them once and you will lose a charge (usually it is 300 times. Full charge and discharge)

When the above 3 points are reached. encountered and the battery is used normally, the battery can be used normally for a longer time than the speed at which your laptop is obsolete. In other words, if you use it normally, you can ignore it.

My MacBook Pro's battery life suddenly decreased. . . .

Battery replacement time is approximately 3-4 hours and can usually be replaced the same day. However, the specific time frame depends on the battery inventory at the repair point.

Simple phone malfunctions can bee repaired the same day, while complex malfunctions can be repaired within five working days. Apple lithium-ion batteries are built into every iPhone, iPad, iPod, Apple Watch and MacBook. to help everyone accomplish various tasks on various occasions. Learn more about batteries to maximize their performance over their lifetime and beyond.

Detailed information

Maintenance of mobile phone batteries:

1. The iPhone uses lithium polymer batteries, which have no memory effect and do not need to be fully charged and discharged each time.

2. Lithium batteries are very sensitive to heat. Try not to work at temperatures above 35 degrees.

3. As long as you use Apple's official power supply, it will switch to direct power mode after full charging, and there will be no overcharging problem.

4. THELithium battery charging process is that the first 80% can be completed by rapid charging in 2 hours, and the remaining 20% ​​can be completed by continuous supplementary charging in 2 hours. .

5. Calibrate once a month and use electrical connections whenever possible.

Baidu Encyclopedia - Apple Lithium Ion Battery

I think we should first develop a good habit of charging, especially lithium batteries!

First of all, the newly purchased battery must be “three full and three empty”. Even if the new battery is used, it must be fully charged three times, then use photoelectricity, and then fully charged. .. and so on, three times.

Second, normally try not to turn on the phone while charging.

Well, wait a minute. In short, if you keep this good habit, I think this situationion will not happen with the battery.

Of course, under the hardware, this kind of situation. The problem must be related to environmental temperature and humidity, as well as battery drop, unstable charging voltage, etc. In terms of software, it could be a system problem or you are often running something that consumes. a lot of video memory, CPU memory and programs (such as 3D games, etc.) will also have this problem.

If that doesn't work, just replace the battery. I think even the battery mounted on it can be replaced.

Haha, actually only 2% of Macbook series users will change the battery. After all, Apple's battery quality is still very good, so it may be difficult for you to find a repairer who can replace it. the integrated battery magazine. It seems to be available on macstore, but it's a bit expensive!
