Smart use of laptop battery

Using is one of the advantages of notebook computers compared to desktop computers. It can be used in various environments. The first batch of batteries were nickel-cadmium batteries (NICDs), but these batteries have a recall effect, are discharged before each charge, and are not easy to use. They were quickly replaced by nickel-metal hydride batteries (NiMH). Today’s most common batteries have no recall effect, and they have more energy per unit weight than nickel-metal hydride batteries. The price of nickel-metal hydride batteries is twice that of nickel-metal hydride batteries. Under the same weight, the three batteries work at a ratio of 1:1. 9.

There are three kinds of important batteries for notebook computers: nickel-chromium batteries; 2. metal hydride nickel batteries; they are usually nickel-cadmium nickel-cadmium nickel mh lithium lithium lithium.

When purchasing or replacing laptop batteries, many users may be unfamiliar with batteries. First of all, batteries and batteries are two different things. The battery consists of a small battery slightly larger than your thumb. It is cylindrical, about 7,8 cm tall, and has a voltage of 3.6 volts. They are batteries, like small batteries, connected in series, what we see are batteries. Here is how to determine how many batteries there are:

One way: unplug the battery and look at your contact number, there are just a few cores. But that is the way of the minister. Let’s see how Cao Chongxiang did it: Look at the nominal number v of your battery, such as 14.4V, and then divide by 3.6 to get 4, which proves that the 4 batteries are connected in series. Look at the capacity of the entire battery, for example, 3800 mAh. It turns out that there are two battery packs mentioned above. Since the capacity of these small batteries is above 1500-2000 mA, they all need to reach 3800 mA. According to these two tests, this cell is 4 times 2 equal to 8 cells.

Laptop battery structure

The battery of a notebook computer is composed of a case, a circuit board and a battery, and the battery is classified as a lithium battery. Battery capacity refers to the number of batteries, and mAh refers to the capacity of laptop batteries.

The circuit board is mainly composed of two parts: the maintenance circuit (or the secondary maintenance circuit) and the capacity indicator circuit, which can handle the charge and discharge and safety of the laptop battery.

The standby time of the laptop battery is determined by its mAh value. Generally speaking, the more cores, the greater the mAh value, and the longer the standby time. The battery life of a notebook is an important number of charge and discharge, and the quality of the product is generally 500-600 times. Therefore, the service life of the laptop battery is within 2 years. After the expiration, the battery will age and the standby time will drop sharply, which affects the mobility of the laptop.

Laptop battery skills

In fact, how to use laptop battery batteries, how to extend the use time and service life and other issues are undoubtedly a problem for laptop users. There are many methods and techniques for using laptop batteries, which require us to use them in daily life. More learning and use.

(1) Go to sleep quickly

temporarily not using the laptop, in order to save battery energy, we can set a processing plan, therefore, the system sleeps for a period of time, but this is a long or short wait for a few minutes, is there a way to make the laptop system go to sleep immediately?

A good way to quickly put the laptop system to sleep is to turn off the Flash screen. With a simple action, pressing the flash will put your laptop to sleep immediately, effectively saving battery life. When you want to use it again, just flip the screen and the system will automatically restore to the last operation.

(2) Screen power saving mode

TFT screen is the most power-consuming part of a notebook computer. In order to use the battery to reduce its power consumption, notebook computer manufacturers have a trick, but generally speaking, they choose to reduce the screen brightness or even turn off the screen.

The screen brightness can be customized in the power handling settings of some laptops. On most laptops, you can adjust the screen brightness through certain shortcuts. Generally there are 6~8 levels of brightness adjustment.

(3) Energy saving setting

Desktop computers use electricity for communication. The energy-saving functions of computers are not paid too much attention to by most people, but the application of energy-saving functions should be paid attention to for notebook computers that need to be battery-powered. How to program to make computer hardware more energy efficient is not a problem for users. All the user can do is to effectively use the energy-saving options in the computer settings.
