Spare lithium battery protection measures

Spare batteries must be individually well protected against short circuit (placed in the original retail packaging or otherwise electrode insulation, such as exposed electrodes affixed tape, or each battery placed in a separate plastic bag or protective case which).

Lithium rated energy method of determining

If no direct labeling lithium battery rated Wh (watt-hours) of energy, lithium battery rated energy following conversion:

1, if known battery nominal voltage (V) and the nominal capacity (Ah), can be obtained by calculating the values of the watt-hour rating:
Wh = V x Ah
The nominal voltage and nominal capacity is usually marked on the battery.

2, if the battery is only marked with mA (mAh), this value is divided by 1000 ampere hours (Ah).

For example: lithium battery nominal voltage of 3.7V, nominal capacity of 760 mAh, watt-hour rating for:
760 mAh / 1000 = 0.76Ah
3.7V × 0.76Ah = 2.9Wh

Several Major Errors in the Laptop Battery Maintenance

Controversy about the battery from the notebook that was born that day, never stopped, because the battery life of a notebook a very important technical indicators, the capacity of the Asus A32-K52 Battery  determines the notebook of this important indicator of good or bad, in the end how to use in order to maximize the effectiveness of the battery to extend battery life? Below we listed the several vulnerable to misunderstanding.

Start three times before using the battery needs to be charged 12 hours

Do not necessary, because the laptop now has improved power management circuitry and charging management system, when the battery level reaches saturation, the control circuit will automatically switch to the off state, so long as the full line, does not mean that you red longer can be used longer.

To prevent memory effect, we should run out of power before charging.

Each charge before the Asus A32-F82 Battery discharge is not necessary and is harmful, the time to prove: battery deep discharge back unnecessary shorten battery life, and can be charged when the battery is used about 10%, of course, when the battery there are still more than 30% of the electricity is advisable not to charge, because the memory effect does exist

Access to power, the battery should be brought down

Of course not, the lithium-ion Asus A32-K72 Battery will allow automatic discharge, the natural discharge of the battery, if there is a power access will appear repeatedly charge and discharge, reduce battery life, but this can not be a normal reasons scored battery
Notebook power control circuit has such a function ---- when the battery reaches 90% or 95% of the charge will be reached through natural discharge time of this capacity for 2 weeks to a month, when a battery idle months or so to be a maintenance battery full charge and discharge capacity, and this time you should be concerned about the battery should "exercise the body, rather than be left idle after recharge.
Even if the battery is unfortunately in the second charge, bring the loss will not be much bigger decline than long periods of inactivity caused by the battery power, your data than your battery or your notebook precious and more, a sudden power not only on the harm to your laptop, and the data irretrievable made you regret!

In Win7 laptop batteries to use time longer setting skills

Users want to take the laptop mobile office, most worried about is the laptop battery is not enough, what skills to make longer notebook battery in Win7 win7 change which is set to make laptop use more energy to do the following take a look at how to set Win7 Asus K72J Battery use longer.
1, the idle power consumption of resources
When a computer is started, it will not have been in full-load operation state, and therefore there will be a lot of idle time, idle time, power consumption has become an important technology in power management. In win7 years idle power consumption has been effectively improved, after a certain period of time does not work in a hardware will enter a low power state to save battery power. CPU hard disk, memory and network elements are using this technology. For example, a full-power operation power consumption 35w CPU idle power consumption is almost zero, only this one will be able to save a lot of electricity.

2, Bluetooth devices to improve power
Win7 detected Bluetooth devices in a low-power state, it will temporarily shut down, that "selective suspend".
Enhanced processor power management
The win7 integrates the latest power management technology, which enables Windows 7 according to the current load and performance
Requirements to dynamically adjust CPU performance.
4, low power audio
win7 will support Intel's low-power HD audio specification, which allows compiled *** into low power state. win7 also supports selective suspend technology, will be in the idle state device is turned off, such as microphones and cameras such USB devices.
5 to start the service by triggering
System services are typically started when the system starts, then resides in the background waiting for the call. In Windows
7, part of the system services only triggered by some event will only be activated, such as inserting a device or change the IP. This can reduce the number of long-running services in the background process.
Adaptive display brightness adjustment
Microsoft said, usually 10-15 minutes-free operation, the display will automatically turn off the computer always restart automatically. But in actual use, there will be more short-term operating conditions in order to better energy efficiency, the technology will reduce the brightness of the display. In addition
It can also use some sensing devices to adjust the display brightness according to the ambient brightness.Asus A32-K52 Battery
7, the network devices to improve power
win7 been strengthened in low-power mode for the radio network controller compatibility enabled only, and only in the case of wireless AP devices support low-power mode. Vista because it can not detect in advance whether or not to support a low-power mode
Type, memory repair BIOS maintenance will lead to a sudden interruption of Wi-Fi. win7 will prevent this from happening, will first detect whether the wireless AP support this mode before entering low-power mode.

8, timer integration
Processor through use spare time for processing instructions gap to achieve energy-saving purposes, but most of the energy-saving technologies require a certain length of idle time to get energy saving effect. This technology by the Windows kernel to terminate the focus was more dispersed multiple timers at the same time, dealt with in a short period of time, thus increasing the processor idle time. In addition, the frequency of activities in the case of using the Asus k50ij Battery when the laptop, win7 will reduce non-critical daemon.
The above is win7 several important improvements in power management, compared to the previous system can save more energy. 3F} K rG above improvements in Win7 laptop battery use time must be extended.

New method: short put short charge most durable lithium ion battery maintenance

Math now you around the number of mobile devices? Phone, MP3, Tablet PC, laptop computers, digital cameras, handheld, navigator and so on, these devices are in use mobile battery-powered, the Asus N61Jq battery life is the most worrying problem.

Knowledge of the phone, for example, affect the battery life in addition to the system power factor, also must understand how to care for the battery, unless you can put up to replace the backup battery or external battery, in fact this phone like the iPhone battery can not replace .

Battery maintenance is possible on a single charge-discharge cycles have little effect, but a long time there is contrast, lithium-ion battery, battery capacity, there will be a loss of one year or more after, and maintenance of the good battery wear and tear will be much better.

The spodumene battery on how to prolong lithium battery life, give you advice on the use of the battery:

The experimental results confirmed that the best way of maintenance of the lithium-ion battery is mild to use, quick release fast charge. The smaller the degree of depth of discharge lithium Asus K52F battery, use the longer, if possible, try to avoid frequent full charge and discharge.

Users, your battery using the 10%, 20% charge can also be the best remaining battery charge in 50% of the time, but try to avoid the phone prompts to start charging low battery, no matter what the circumstances are not to run out of battery power. If you're out, try to use a larger capacity battery or mobile power.

In addition, the use of environmental temperature also have an impact on the lithium battery life (30 ℃) is too high or too low temperature will be formed on Asus A32-F3 Battery  life loss. Such as regular laptop connecting adapter power usage, it is best to remove the battery to formation damage, actually this is not rechargeable batteries, because it is no longer charging after the battery is fully charged, do not pay attention to the bottom of the laptop use ventilation situation makes overheating, this is the impact the battery life of the murderer. Of course, if there is a better use of the environment or the cooling pad, the battery can be avoided in the blackout loss of unsaved data.

Intel new Core i7 Extreme the core breakthrough in the 3GHz speed of mark

Intel has begun delivery of 21 new processors designed for laptops and desktops, including the new Core i7 chip, the reference clock frequency of 3GHz, hit a new high speed mobile processor based on the Ivy Bridge microarchitecture.
4-core Core i7-3940XM Extreme Edition will replace the Core i7-3920XM, the latter a clock frequency of 2.9GHz. According to the price of Intel released Saturday, Extreme Edition chip is priced at $ 1,096 from the grant in 1000, compared with the 3920XM, the price does not change.
Extreme Edition chip is mainly used for the game version of the laptop, Intel's highest performance mobile processor. Intel and its rival AMD generally will increase the clock frequency of the chip so that claims to be the king of the performance.
Depending on the application, the higher clock frequency may improve performance, the clock frequency will increase With the reduction of the chip size, the leak will be reduced, said Jim McGregor, the founder of the consulting firm Tirias Research.
Increase the clock frequency also make chips more energy consumption, thereby reducing the time and life of notebook battery life, McGregor said. Only a very limited part of the user, for example, to require such performance gamers. For the pursuit of higher performance-per-watt manufacturers is to increase the number of cores, this practice so far has been the development of the decade.
"With multi-core, the frequency has become a secondary issue," McGregor said.
However, users quite this obsession of people, they always think that the clock frequency is very important to enhance chip performance, McGregor said.
"We still GHz or the number of cores obsession, because we are simple-minded consumers, we need the figures to convince themselves, but in fact, the clock frequency is really not so important," McGregor said.
The new Ivy Bridge chip has a feature called Turbo Boost, each core clock frequency which can be based on the required performance increase or reduce. This feature in the Core i7-3940XM Extreme Edition also need the right performance, the main intent is to provide for a specific application.
Intel Core i7 processor clock frequency to improve the thin and light mainstream notebook. New 4-core Core i7-3840QM reference clock frequency of 2.8GHz, compared to before the fastest chip, the 2.7GHz Core i7-3820QM also reached a new high. Both chips are priced at $ 568.
Intel also began to be delivered for the new desktop Core i3 and i5 Ivy Bridge processor, dual-core Sandy Bridge Celeron processors for low-power notebook.

Third-party Laptop Bbattery three Major Issues

● Third-party laptop battery safety:

    The the earlier Asus N61Jq battery door event had created a hubbub. In August 2006, it came out of a brand laptop batteries prone to fire problems and may burn the whole laptop. August 14, 2006, the brand recall order was issued in the United States, announced the recall of 410 laptop battery may cause a fire, and said the defective battery supplier production.

    Subsequently, the supplier admitted the statement, and said: the battery is defective main reason is due to the production process mixed with a tiny metal fragments, these fragments led to short-circuit the battery and computer charging system contact, causing overheating or explosion.

    Subsequently, the major brand notebook manufacturer issued a recall order in succession defective laptop batteries made compensation for the matter to consumers.

    The battery door "event to enable consumers to re-recognize the laptop battery - if the laptop battery quality problems, it may burn down the whole laptop; if we use the original laptop battery, battery lead to accidents get compensation .

    For consumers, safety is always the most important, followed by product unexpected compensation package. If I use the original Asus A42-A6 battery, battery alone burned, or the battery lead to the whole laptop totally destroyed, I can get compensation from the notebook manufacturer. However, if I use a third-party laptop battery, then at the time of the accident, it is difficult to find a clear compensation scheme.

    Therefore, for a third-party laptop battery, how to ensure the safety of the product, how to provide a reasonable compensation package in the event of an accident, is absolutely the greatest concern of consumers.

    ● comprehensiveness of the third-party laptop battery:

    Variety of laptop mold, also a variety of laptop battery die naturally. Single from our recent evaluation of notebook prototype, you can pick out several different styles of laptop batteries die.

If you want to operate a third-party laptop battery, but would like to become bigger and stronger, of course, is impossible to rely on a single species, at least to the extent of covering all popular laptop. However, the development of laptop batteries die takes a lot of money, which is "Why has long been no third-party laptop battery," the main reason.

    Therefore, for third-party Asus K52F battery, how to ensure that the batteries die comprehensiveness, but also a problem of concern to consumers.

    ● the need for third-party laptop battery:

    The final problem is the need for third-party laptop battery. Plainly, that is - the original laptop battery not only has high security, and also be able to provide unexpected compensation, and incomplete types of mold problem does not exist, then why do we need to purchase third-party laptop battery it?

    Currently, the price of the original laptop batteries generally higher, except very few brands laptop battery price is around $ 300, the price of most brand notebook batteries are around $ 600, the price of some brand notebook battery even more than $ 1,000 .

    Specific matter inside the company do a survey of colleagues answer is basically: "original laptop battery price is too high to buy more in order to increase the life time of a battery is too luxurious, if the price is cheaper, I'd would consider buying a few pieces to prepare for contingencies.

    Visible, only the price of the third-party laptop battery cheap enough to arouse the consumers desire to buy, which is the key to determine the success or failure of a third-party A32-K72 battery.
