Wired: Long-term connection laptop power harmful battery Health

Laptops are an important part of many people's lives, but in everyday use, we don't pay much attention to the details. One of them is that most people will turn on the power and use the laptop when conditions are available, which is more secure and safe. But the US Wired magazine reported March 10 that the battery would be damaged by charging at all times. What the hell is going on? Let's take a look. The message comes from the CEO of Isido Buckman Electronics (cadexelectronics). "The ideal battery status should be to charge it up to 80%, then disconnect, and then recharge after the power is lowered to 40%." "he said. The theoretical basis of this theory is related to the working characteristics of lithium polymer batteries. The key to storing electricity in this battery is to input the voltage into the lithium ion. The higher the charge, the greater the voltage strength and pressure that a single lithium ion needs to carry. Long-term overload can significantly reduce battery life cycle. According to data statistics, the same type of battery if the full charge and discharge (100%) can only maintain 300-500 times health cycle. And if you start discharging at 70%, the number of healthy cycles jumps to 1200-200 times. Long-time connection power is more harmful than this. The battery has a natural aging process, and high temperatures accelerate the process. The high temperature caused by intermittent charging will cause bubbles in the battery, and have a fatal effect on the health of the battery. So not only pay attention to timely charge and discharge, but also pay attention to the working environment of the notebook and get the timely cooling. Of course, when you're busy working on a computer, I'm afraid no one can care what the battery is, whether it's a plug or a recharge. So it would be nice if the operating system could be a reminder to the user at a particular charge. Unfortunately, neither Apple OS X nor Microsoft Windows has such a feature at the moment. But as the saying goes, a simple way is to measure your laptop's electricity from 80% to 40% times, and then set the alarm clock when you use it. Although this is not very troublesome, but for the sake of your battery, it is worthwhile to pay a little effort.
