Laptop must watch the use of laptop charging skills _ Application Skills

First, we asked a dealer who sells laptops for a long time and got the following answer:

Q: Do you need to activate your new laptop?

A: Need to activate, one or two times is enough, each time preferably more than 10 hours;

Q: So, how to properly charge? Some people say that every time you use the machine to automatically shut down and recharge better. Some people say, do not have to pay attention to, any time can do.

A: This does not matter, always charge on the line.

Q: Many people in the use of external power supply, in order to save battery loss, unplug the battery use. Does this approach promote?

A: Yes, it is advocated.

Editor's summary: from the dealer's mouth, we can see that every time he gives consumer guidance to buy a computer, he advocates: the new laptop, to activate the battery, the lithium battery has no memory effect, so it can charge at any time, often external power to use the notebook, the best to unplug the battery.

Let's listen to the next answer from an engineer who specializes in lithium-ion batteries on laptops.

Q: Do you need to activate your new laptop?

A: Do not need, because those notebook batteries in the factory have been activated, as long as the normal use of the line;

Q: So, how to properly charge? Some people say that every time you use the machine to automatically shut down and recharge better. Some people say, do not have to pay attention to, any time can do.

A: It's OK anytime. Each use to machine automatic shutdown and recharge better, so that each charge and discharge are fully utilized, battery life long. Similarly 500 times, "charge at any time" may be used up 500 times a year, and "each use to machine automatic shutdown and recharge" only two hundred or three hundred times, natural latter better.

Q: If charged, half of it is stopped because of a power outage. Then fill it up, is this a charge or two times?

A: Count two times.

Q: Is this a so-called "memory effect"?

A: Lithium batteries have no memory effect.

Q: Many people in the use of external power supply, in order to save battery loss, unplug the battery use. Does this approach promote?

A: Yes, it is advocated so that electricity is not transferred from the external to the built-in loss.

Editor's summary: From this engineer's answer we see that he advocates that the new laptop does not have to activate the battery for a long time, and that in order to prolong the life of the laptop battery, it is best to drain the battery and recharge it every time;

Finally we interviewed the friend is a "monastic years" of the book players, in the notebook technology has a lot of unique insights to see how he answered these questions:

Q: Do we need to activate the new laptop we bought?

A: No, because the batteries in the notebooks were activated when they were shipped;

Q: So, how to properly charge? Some people say that every time you use the machine to automatically shut down and recharge better. Some people say, do not have to pay attention to, any time can do.

A: Do not deliberately to pay attention to, generally are above 100% stop charging, less than 95% before charging. This technology is not limited to IBM's batteries, because the power management chip is a ALMTL product, and now the battery manufacturers basically use this solution. Of course, some of the super cheap laptop batteries, I can not guarantee.

Q: If charged, half of it is stopped because of a power outage. Then fill it up, is this a charge or two times?

A: Count two times.

Q: Many people in the use of external power supply, in order to save battery loss, unplug the battery use. Does this approach promote?

A: There is no need to remove the battery. The battery has built-in protection circuit, in the case of full battery charge, does not cause the loss of the battery, and secondly, if the battery is removed and suddenly power off, the notebook itself will cause bad image.

Editor's summary: This book player advocates: The new laptop does not need to activate the battery for a long time, in order to extend the life of the notebook battery, it is best to use the battery to recharge every time; often external power use notebook, in order to protect the notebook, it is best not to remove the battery.

Page 4th: Three major disputes over the use of notebook batteries

From the above about laptop dealers, laptop battery engineers and computer players, you will certainly understand how to treat your laptop battery. According to the data, the new battery activation work has been completed before the factory, the new notebook battery with a little power is to avoid natural loss to the battery damage, do not have to listen to those dealers said "to be activated by more than 10 hours" and so on.

Notebook computer Lithium battery life is limited, generally after 300~500 repeated charge, it will not be filled. Therefore, according to our current grasp of the data can be seen, in order to maintain the "maximum life" of the battery, or as far as possible to use up the electricity to recharge. However, small series to remind everyone, we buy a notebook is to use, is to let it become their work, learning weapons, all day so care to care to go, don't you too troublesome?

For the third controversy, our point of view is: Do not unplug the battery when using an external power supply. From the lithium-ion battery point of view, because the lithium battery has a certain number of charge limit, so take it off from the notebook, or can prolong the battery service life. But this approach is very dangerous for the laptop itself, and if it suddenly loses power, it will affect the notebook itself due to current and other reasons. As some big manufacturers think about it, like ThinkPad, it has a special battery protection technology that only charges when the battery is below 95%.
