Why not keep your laptop battery connected

Laptops have long become an indispensable attribute of every modern person - a pass to the magical world of the Internet. We use them to work, play and communicate from anywhere in the world. And if you do what most people do, keep your laptop online at home and at work. No way.

If you want to squeeze the maximum power out of your laptop batteries, disconnect it from the network as soon as the indicator shows 100 percent charging. A little earlier.

The head of Cadex Electronics, Isidor Bushmann, believes that ideally you need to charge the battery to 80 percent, then turn off, wait until the charge level drops to 40 percent and turn on again. This will extend the life of your battery up to four times.

The reason lies in the voltage level of each element of the lithium polymer battery. The higher the percentage of charging, the higher the voltage level. The higher the voltage level, the higher the load on each element. This load leads to a reduction in the discharge time. According to the Battery University website, if a laptop can produce 300-500 discharge cycles when charging up to 100 percent, then when charging up to 70 percent, the number of these cycles increases to 1200-2000.

Bushmann knows this well because his company sponsors Battery University. In addition, he argues that battery life shortens not only the constant connection to the network – temperature also plays a significant role in this process. From overheating, the battery cells can expand and bubbles can form in them. This battery won't last long.

To avoid these troubles, it is better not to close the lid of the laptop and not to keep it on your lap.

Bushmann admits that his advice to keep charging levels between 40 and 80 percent is easier said than done. Keeping the indicator under control during operation is not very convenient. “But it’s not that hard to at least charge it to about 80 percent each time. And when you're going on a trip, stop charging a little bit before reaching 100 percent, he says.

Some users have adapted to calculate the time it takes a computer to discharge from 80 to 40 percent and start a timer. They do the same with the time the batteries are charged. If it helps to save money, why not?
