Smart use of laptop battery

Intelligent use of notebook computer batteries using rechargeable batteries The use of rechargeable batteries is one of the advantages of notebook computers relative to desktop computers, which can greatly promote the use of notebook computers in various environments. The earliest batteries are nickel-cadmium batteries (NiCd), but these batteries have a recall effect and must be discharged before each charge, which is not convenient to use. They were quickly replaced by nickel-metal hydride batteries. Not only did the nickel-metal hydride batteries have no recall effect, but they also added 10% of the power of each component. At present, the most common battery is a lithium battery, which has no recall effect. The power per unit component is higher than that of a nickel-hydrogen battery, and the price is twice that of the latter. Regarding the same component, the working time ratio of the three batteries is 1:1.2:1.9. There are three kinds of batteries used in notebook computers: 1. Battery; Ni-Cr battery, 2. Nickel metal hydride battery, 3. lithium battery. They are usually expressed as: nickel cadmium nickel cadmium, nickel hydrogen nickel hydride, lithium lithium lithium. When buying or replacing laptop batteries, batteries may be unfamiliar to many users. First of all, battery and battery are two concepts. The battery is composed of several small cylindrical parts that are slightly larger than the thumb, about 7.8 cm high, and the voltage is 3.6 volts. They are batteries, they are like small batteries, they are connected in series, they are the batteries we see. The following tells you how to judge how many batteries there are in a battery: One method: unplug the battery to see the number of contacts, there are several. But this is the minister's method. Let's take a look at how Caochong measures the image: look at the nominal number of v of your battery, such as 14.4v, and then divide by 3.6 to get 4, and then prove that it is 4 batteries connected in series. Then look at the capacity of the entire battery, such as 3800mAh, and then prove that the two sets of batteries mentioned above are connected in series, because the capacity of those small batteries is 1500-2000mAh, or even more, it is necessary to adjust the two sets to 3800mAh. According to these two standards, the battery is 4×2u003d8 batteries. Laptop battery pack into a laptop battery is made up of a casing, a circuit board and a battery pack, and is a lithium battery. Generally speaking, the battery refers to the number of batteries in the battery, and the mAh refers to the capacity of the laptop battery. The circuit board is mainly composed of two parts: a protection circuit (or secondary protection circuit) and a capacity indicator circuit. The standby time of the notebook battery is mainly determined by the mAh value. In general, the more cores, the greater the mAh value, and the longer the standby time. The life of a laptop battery is important to be measured by the number of charging and discharging, and the quality of the product is generally 500-600 times. Therefore, the service life of the laptop battery is less than 2 years, and the battery will age after expiration, and the standby time will drop sharply, affecting the mobility of the laptop. In fact, how to use laptop battery batteries, how to extend their use time and the number of days of use, and other problems are undoubtedly a difficult problem that plagues the hearts of laptop users. The use methods and skills of laptop batteries There are many kinds, which requires us to learn and use more in daily use. (1) Enter the hibernation state quickly. In order to save battery energy, we can establish a power processing method to let the system enter the hibernation state after not using the laptop for a period of time. However, this may take a few minutes. Is there a way to put the laptop system to sleep immediately? A good way to put your laptop system to sleep quickly is to simply turn off the flash screen. Pressing the splash screen is just a few steps to put the notebook into sleep mode, which is very helpful to save battery power. When the requirement is used again, just turn on the flash screen, and the system will automatically return to the state before the operation. (2) Screen power saving method TFT screen is the most power-consuming part of notebook computer. In order to use battery time to reduce the power it consumes, notebook computer manufacturers have their magic weapons, but generally they choose to reduce the brightness of the screen or even turn it off. Screen method. The brightness of the screen can be customized in the power handling settings of some notebook computers. Most laptops can adjust the brightness of the screen through specific shortcut keys. Generally speaking, there are 6 to 8 brightness levels. (3) Energy-saving settings Desktop computers use alternating current. Most people may not be very important to the energy-saving features of the computer, but it is necessary to use batteries to power the laptop.
