Battery Application Maintenance Guide books
Compared with desktop and notebook than the good of the greatest advantage of mobile Laptop Battery portability, which with notebook in the application of an integral rechargeable battery. Rechargeable battery a great convenience for notebook use in complex environments, whether in traveling or in a coffee shop, one Taiwan "unplugged" notebook computers have become the most beautiful landscape. In fact since the inception of notebook computers, manufacturers have not stopped the development of laptop batteries and upgrades, from the initial use of nickel-cadmium batteries (NiCd) batteries to Nickel Metal Hydride (NiMH), and then to the widely used lithium-ion battery (Li -Ion), laptop battery has experienced long-term escalation of the revolution. At the same time, increased battery capacity in the best possible circumstances, the notebook hardware manufacturers also focus on the development of energy-saving products, such as low-power processor, SSD hard drives, LED backlit screen applications such as laptop machine are effectively reducing the power consumption, The purpose of doing so, environmental protection, the more important is to give users a longer notebook battery Hp HSTNN-DB20 battery life.
Long-lasting power station notebook
However, the laptop battery life and the use of time, or let the user afflicted. Often do not use the notebook unplugged friends is not difficult to find, with the use of time increases, the notebook battery capacity seems to become smaller and smaller, and the original can be used three hours, and now only 2 hours is necessary to stop clamoring; some friends in to buy business notebook was told the battery can be used 6 hours (or more), while the use of only carried out when we got there, even browse the Web, edit documents some simple operation, battery life is still hovering around the 2-3 hours, is being profiteers blinded or because incorrect use?
Notebook lithium batteries
For these problems, we built-in lithium-ion battery Hp 395789-001 battery from the notebook's basic structure, and users will encounter in use some common problems, we should explain how the proper use and maintenance of lithium-ion battery, so that your beloved The notebook was a motivated mobile power stations.
As mentioned earlier, the vast majority of notebooks currently on the market adoption of lithium-ion batteries, lithium-ion battery from the pen casing, circuit boards and batteries composed of three parts. In the case apart, we will see a section similar to ordinary dry battery power-saving core, but in fact the chemical composition and batteries all have very different sizes, storage capacity for non-regular battery can hold a candle to.
Lithium-ion battery chart
Lithium-ion battery is characterized by large capacity, light weight, the memory effect of nickel-cadmium batteries are also far less obvious. In the evaluation and introductory Hp 396008-001 battery article, we often see the "x-cell battery", "mAh" and other words, the so-called core cells of several "core" refers to the number of batteries within the battery, at present there are three main laptop battery core, 4 core, 6-cell, 9-pin and 12-core, mainstream notebooks on the market more than standard 6-cell battery life is generally 3 hours or so, pay attention to what we call "life" is not equivalent to "standby time" , users must purchase the rhetoric of rational business judgments. A higher demand for mobile office users can buy large-capacity 9-pin and 12-cell battery, of course, a number of relatively expensive price, we will increase the weight of laptops.
The internal structure of the battery
mAh value determines the battery Hp Pavilion dv9000 battery(Hp dv9000 battery) standby time, mAh value is higher the longer the battery usage time. We usually say battery life is determined by the number of battery charge and discharge decisions, the general lithium-ion battery charge and discharge times for the 500 or so, but not the charge will be included in each account, the charge will be counted as more than 80%一次. As a general user's need for frequent recharging, laptop battery life in 2 years or so, and then it would rapidly aging, standby time greatly reduced, which is almost all notebook warranty regulations, will the battery warranty period is set to 1 or so, the reasons for .
Lithium-ion batteries are very sensitive to temperature, the ideal temperature is 20-30 degrees Celsius, when the temperature is below 6 degrees Celsius, lithium-ion (Li-ion) batteries will self-discharge of 5% per month, which is the best Save mode, but if when the temperature dropped to zero degrees Celsius, the original battery capacity will be reduced to 80%, when the temperature at minus 10 degrees, the capacity dropped to 50%, when the temperature dropped to a certain extent, lithium-ion battery Hp EV087AA battery there is a total loss risk.
Hot environments
Cold environments
Since I can not tolerate low temperatures, then the lithium-ion batteries in high-temperature environment, what is done? Based on case studies and more than proved that under high temperature lithium-ion batteries will greatly shorten the life span and may even be an explosion.
Laptop Cooling Base
In daily use laptops to pay attention to body temperature, the temperature is too low as far as possible not to use the environment, while also note that body heat, it is recommended by means of cooling pad for notebook cooling time, so not only can extend battery life, other internal components of the notebook is also good for life.
In addition to purchasing large-capacity battery Hp EX942AA battery , by setting the power-saving mode, adhere to a correct way to use is to extend the battery usage time effective way. First, we screen and graphics by adjusting the operating mode to reduce power consumption machine. Large-screen notebook power consumption, the general will Laptop screen brightness set to grades 6-10, who are able to be around 50% brightness, but when used at night to about 30% of brightness has been completely sufficient. We know that an independent graphics to provide better high-definition decoding, providing users a clearer lifelike video entertainment experience, but power consumption is relatively high, if your notebook is equipped with dual-graphics and supports graphics switching, it is recommended in the absence of the case of an external power supply is set to separate the use of integrated graphics, although the results will be discounted high-definition, but it can be extended endurance time was 20-35 minutes.
Set standby mode
Second, temporarily using a laptop computer, you can put the computer into standby. We usually will set the power options will be closed roof of the relevant directives set to auto-standby. Specifically, in Windows "Control Panel" and select "Power Management Properties" dialog box, enter the "Advanced" option, the "power button" is set to close the portable computer, "standby", so that can be very convenient to reduce the laptop when not in use at the moment the electricity consumption, thereby extending the use of time, of course, different versions of the operating system settings in the way there will be nuances.
Unplug peripherals can also be energy-saving
In addition, the external device will increase the machine Hp Pavilion ZT3000 battery power consumption, is therefore proposed that the mouse, U disk, memory card and other external equipment, disconnect and turn off the wireless network adapter, infrared port and Bluetooth, and even reduce the processor's operating frequency, these are In exceptional circumstances the necessary means to extend battery life.
We have mentioned earlier, the battery life is the decision by the battery charge and discharge times, the constant charging and discharging operations, will accelerate the aging of the battery is damaged, so how to properly charge and discharge will become a key element to extend battery life. Many consumers purchase notebook computers will be told to charge and discharge completely three times, in fact, even in everyday use, we should try to ensure the power run out after filling. The first application with the notebook compared to nickel-cadmium batteries, lithium battery memory effect, while not obvious, but still does exist, but a full charge and discharge is the best way to avoid the memory effect.
Complete charge and discharge will help extend battery life
Most laptop battery at full power, full power, the battery charging circuit within the state is still open, so there is an external band of energy, it is recommended not to use the battery as far as possible, not with the battery in the case of multiple plug an external power supply, because power relatively abundant, each time an external power supply plug on the equivalent of charging time, is the same as the laptop battery in the aging step forward has been on the road.
Charge should also be cautious
The battery discharge must comply with certain preservation rules, lithium-ion battery deep discharge more serious consequences may result severe battery failure or total loss, and thus the battery store about three months later, it is recommended the battery Hp 337607-001 battery out to re-charge the battery in order to avoid excessive self-discharge.
Described above, are the daily use of laptop battery standard, while the last two years, many consumers have been repeatedly exposed laptop battery explosion, spontaneous combustion and recalls the incident shock, lithium batteries have a panic fear of the psychological. In fact the battery explosion happened probability is very low, annual shipments of notebook batteries in the millions around the probability of the occurrence of explosion is almost equivalent to buying lottery tickets in the first color, and in the bombings, there is partly due to users caused by improper.
Laptop Battery Explosion
Laptop battery ignition
Triggered laptop battery cause of the explosion, in addition to the circuit the battery outside of its own heat and humidity are mainly two points, how to cool the notebook we have already talked about the need to pay attention to is never in the wet environment using a laptop, although some of The so-called "three defenses" product known as waterproof, but generally refers to the set up between the keyboard and the internal components of a sealed compartment, blocking the liquid from the keyboard into the laptop internal gap in-depth, while the laptop battery is not part of the defense capability of liquid .
To protect books from damp
Then the liquid or moist environment on the laptop battery, what damage? In the humid environment, the laptop battery is prone to short-circuit the internal Hp 337607-003 battery circuitry, causing the circuit failure is likely to directly harm notebook, or cause the battery self-ignition and explosion. However, users do not need to worry too much, as long as the guarantee not to use high temperature and high humidity environment, notebook, stick to the correct battery usage, the battery is basically the probability of explosion could be ignored.
