Notebook battery usage specification

In the last issue of 'How to Buy a Notebook: Details of Success and FailureToday’s editor wants to talk to us about the proper use of laptop batteries. If you have just had a laptop, or your laptop’s battery life has dropped significantly, you might as well take a look at how to make the most of your laptop’s battery. The laptop battery is a kind of performance that the laptop is better than the desktop computer. It can provide users with a battery life according to the time without plugging in the power. Of course, the battery life can be long or short, but how to make the best use of laptops? Battery structure Currently, lithium batteries are the best-selling batteries on the market. The laptop battery is composed of battery core, maintenance board and maintenance shell. The battery pack is responsible for power storage, and the maintenance board is responsible for safe operation. The standby time of a notebook is determined by how many batteries there are. At present, 6-cell batteries and 8-cell batteries are the most popular on the market. Currently, the most widely used battery on the market is a lithium battery. First, let us look at the internal structure of the laptop battery. After disassembling the notebook battery, we will find that the notebook battery battery is not much different from the ordinary dry battery. It is a series of battery parallel circuits. Generally speaking, notebook batteries are limited by the capacity of a single battery and the voltage required by the notebook battery. Generally, series connection and parallel connection are used to ensure their working voltage and battery capacity. In short, it is made up of three batteries in series to reach the rated voltage of the notebook. Then connect a set of the same 3 batteries in parallel, do not increase the voltage, but need to increase the capacity. How it works Next, let's take a look at how the laptop battery works. Let's talk about voltage first. It is important to know that the power source of a laptop computer and the power source of a battery are not the same. Battery power, battery output is pure direct current, battery voltage is impossible and needs to be planned very high, the chemical characteristics of lithium batteries determine the output voltage of a battery can only be about 3.6V. Regarding the power supply, an important requirement is to further stabilize the input voltage and perform filtering to ensure stable operation when the power supply function is not very good. After the voltage is stabilized, the voltage is divided into two parts: power supply and charging. Notebook capacity is important to distinguish according to the mAh marked on the battery. Of course, the more cores, the greater the capacity of the laptop battery and the longer the duration. But it cannot be generalized. If the notebook consumes a lot of power and the hardware with high configuration runs fast, the battery life will naturally decrease. In addition, we need to remind us that the laptop battery must be used normally, and it is best not to disassemble or replace it. And under normal operating temperature, it will cause adverse effects on the battery in order to damage the battery. After the laptop battery is used for a long time, the battery loss is unpreventable, and the loss rate will be very high, as high as 30-40%. Many friends have heard about maintenance skills, and the battery is activated after charging and discharging the laptop just bought. In fact, this is unnecessary. The current notebook has a conduction circuit for charging and discharging, and it will not charge as long as the battery overflows. Many people have the habit of inserting batteries where they are not used. Ensuring that the battery is always on the machine is the best plan to prevent both dust and sudden power failure. But after using the laptop battery for a month, it is best to fully charge it once. Since lithium batteries generally have a processing chip and a charging control chip, the processing chip has a series of values u200bu200bsuch as registers, capacity, temperature, charging status, and number of discharges. After fully charging and discharging, correct the incorrect values u200bu200bin these registers to make the charging control and nominal capacity of the battery conform to the actual situation of the battery. I believe some consumers have heard of the recall effect of laptop batteries. This is true, but the recall effect only exists in nickel-cadmium batteries, not in lithium batteries.
