Cell phone battery classification

                     Cell phone battery classification

       We use our battery-powered products almost daily, and we'll be getting more exposure to it later, but do we really know the battery's quality and classification?
       Currently cell phone batteries can be roughly divided into three categories, original battery, fake battery and domestic brand battery.
       The original battery is the mobile phone brand certification or the specified battery, the performance and compatibility of these batteries is certified, the technology will also get the brand's support, is the consumer's first choice.
       Fake batteries are mostly from the cottage factory, low cost, multi-use inferior batteries, standby time is very short, and unstable, the output current is not stable, prone to voltage drop after the battery is used for some time, no protection circuit, easy Damage, news reports common electrolyte leaks, explosions, etc., are caused by fake batteries.
        The third is a domestic brand battery, or as a compatible battery, that is, a third-party manufacturers of batteries based on the standard of a certain brand of models.
       People should pay attention to the purchase of cell phone battery, one cell phone battery nominal voltage and your cell phone voltage to be consistent. At the same time, can be switched on experiment. The second is to obtain the relevant technical quality supervision department of the battery sampling test of the document, the indicators include the battery capacity can be clear at a glance, from the battery capacity indicators. Third, pay attention to save the warranty card. Specific purchase from the following five aspects.
       Fake and shoddy batteries exist in the general problem is: the battery core components of poor quality of battery chips, insufficient charge, discharge time is short, anti-sabotage performance is poor, the standard battery capacity and the actual discrepancies.
        Genuine mobile phone batteries generally have the following appearance characteristics: Battery label using secondary printing technology, under a certain light, from the bevel, the bar code part of the color was significantly blacker than the other parts, and touch up by hand, feeling slightly more than other parts Convex, many original batteries have this feature. Genuine battery label surface with white metal scratch, there are traces of similar pencil across. Battery case made of special material, very strong, not easy to damage, under normal circumstances is not easy to open the battery case, the battery looks tidy, no extra burr, the outer surface has a certain degree of roughness and feel comfortable, the inner surface smooth, light Can see the fine vertical scratches.
        The width of the battery electrode is the same as that of the cell phone battery. The corresponding position below the battery electrode is marked with "+" and "-" marks. The isolation material between the battery charging electrode pieces is the same as the material of the shell but not the same. Battery into the phone should feel comfortable and comfortable. Battery lock part of the appropriate pressure card, solid. Battery label clear writing, with the battery type corresponding to the battery part number. The battery manufacturer should outline a clear, and security signs bright, looks three-dimensional.

Weigh the weight

      Under normal circumstances, the lithium-ion battery lighter weight, each battery is about 100 grams; taking into account the obvious characteristics, can not be arbitrary counterfeiting, we can use the method of measuring the weight of the phone battery to identify whether the battery belongs to " Selling dog "type, after all, other types of batteries, and lithium-ion batteries in the weight difference is relatively large, simply called a weight, if the battery is too much weight or too far from the 100 grams standard, it can be roughly inferred The battery is fake and shoddy products

Look at the phone's appearance

       Here to see the appearance of the phone, in fact, refers to a careful observation of the appearance of the cell phone battery color, whether the appearance of the phone with the same color. Under normal circumstances, the appearance of genuine color cell phone battery with the appearance of color is exactly the same. Therefore, we can just picked the battery is installed on the phone to see if they are the same color, if the appearance of the color between them, there is a clear color difference, the battery is likely to be fake and shoddy products. The texture is different
        There are some types of cell phone batteries, we can completely in accordance with the texture of hard or not, to identify the authenticity of the battery. Press the cell phone battery arched junction, and use your fingers to directly feel the point of the soft and hard degree. Usually, the texture of the genuine cell phone battery is softer, but it also shows a certain elasticity. Especially when the battery is inserted into the cell phone, there is a smooth and non-blocking feeling of inserting freely, With a very harmonious, stable lock; the other hand, poor quality of the battery is relatively hard on some, and the battery is installed, it is not easy to "slide" into the cell phone battery slot.

Look at the charging effect

       In general, the superior performance of mobile phone battery, the internal over-current protection device, once the external short circuit occurs in the cell phone, triggering a large impact current, the over-current protection device can automatically cut off the charging circuit to avoid cell phone battery due to high current Impact and damage or burned phenomenon. Poor batteries, there may not be over-current protection device; so long after charging the battery, there may be hot-rolled battery case phenomenon, serious smoke may occur. If the battery does not take long to charge, there is a phenomenon of hot, then the battery is inevitable ten thousand.
       No matter what we buy to learn to distinguish between the authenticity of good or bad, buy the battery even more so, because it determines the life of all your electronic products, so learn to distinguish, choose the right battery store, buy the right battery is your The greatest help for cell phones.

Every day use Tips to extend your ASUS A501LB5200 laptop’s battery life
1.Keep the ASUS A501LB5200 battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
     2.Do not expose the Li-ion A501LB5200 battery to extreme temperatures. Do not leave your battery outside in the cold or in your car in the summer. Cold batteries can’t create very much power and hot batteries will discharge very quickly.
     3..Avoid allowing your device to discharge completely. Constantly recharging a lithium-ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can.

     4.Keep vents clear – don’t put your ASUS batteries on a fluffy pillow or a cushioned service that will cover vents and trap heat.
     5.Chargeable batteries will wear down quickly, when they are only charged for a short period of time. When the laptop is not in use, such as at bedtime, plug it into an outlet and leave it to charge until the battery power is full.

     6.Don’t pack your laptop away in a backpack or other enclosed space when the ASUS A501LB5200 11.4V battery is still warm, trapping the heat. A battery that is frequently hot to the touch will lose life a lot faster than a battery that isn’t constantly being stressed. Worst of all: if your laptop crashes or refuses to shut off properly, the battery can get extremely hot when packed away in your bag.
    7.Defrag regularly – The faster your hard drive does its work – less demand you are going to put on the hard drive and your ASUS Series battery. Make your hard drive as efficient as possible by defragging it regularly.

    Choose a laptop battery to choose good quality, because the battery is too important for the laptop, and we can do for you is to provide preferential prices, reliable quality and excellent service.

Your laptop battery deserves to be cherished

    Your laptop battery deserves to be cherished

  

       Our laptop battery is very important for the computer.As we all know, laptops are extremely convenient to use. You can take them anywhere and get some work done, or spend some time surfing the internet, or even watching some videos or chatting with your friends. Often there will be no laptop power occurred,there are power outlets available as well as WiFi sources in many places.


       However, sometimes you can't find an outlet, or can't reach the closest one to where you happen to be sitting. For those times that you do need to depend on your battery, you need to pay careful attention to your laptop battery life. If your battery dies while you are in the middle of an important conversation, or if you have several files open that aren't saved, then it can cause some serious troubles. And if you happen to be talking to somebody and get cut off, they may take it the wrong way and get angry at you.

       There are few things you can do to maximize your laptop battery life. These can help you to avoid those embarrassing situations, and keep you from losing any unsaved work.

       When the screen goes blank, one thing you can do right away is to check your power settings through the control panel. There are several options, designed for several situations. For using the battery, you can check the one that maximizes your laptop battery life, or at least balances out your battery life with your processor speed. The fastest processor speed would give you the shortest laptop battery life, and vice-versa. Just be sure to switch back into maximum processor speed when you are plugged in.

       Another way to save battery time is to go easy on the processor and memory dependent software. Try and keep as few applications open as possible, and try to avoid using video at all costs. Video is a huge drain on system resources, and eats up your laptop battery in a hurry. Streaming video, streaming music, and games are all resource intensive activities that should be minimized.

       You should also keep in mind that every time you drain and charge your battery, the amount of time you get out of a full charge decreases a little bit each time. After about a year of intensive use, you will likely need to switch your laptop battery. They are pretty cheap, so you may consider buying a couple of backups if you are going to be doing some extended work where AC is unavailable, like on an airplane or in an extended lecture.

       After learning these tips, your laptop should be at least a little more used than before, playing games with you or talking to people will not be angry because of a sudden blackout of your laptop battery.

How Batteries Work

                            How Batteries Work



       Whether it is a cell phone or a computer, you need a battery, but do you really know how the battery works? Really understand the battery?
       Batteries have three parts, an anode (-), a cathode (+), and the electrolyte. The cathode and anode are hooked up to an electrical circuit. Electricity, as you probably already know, is the flow of electrons through a conductive path like a wire. This path is called a circuit. 
       The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. You can think of this difference as an unstable build-up of the electrons. The electrons wants to rearrange themselves to get rid of this difference. But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons.
       In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit. However, these electrochemical processes change the chemicals in anode and cathode to make them stop supplying electrons. So there is a limited amount of power available in a battery.
       When you recharge a battery, you change the direction of the flow of electrons using another power source, such as solar panels. The electrochemical processes happen in reverse, and the anode and cathode are restored to their original state and can again provide full power.

Just six months on the cell phone battery: Do not charge

Just six months on the cell phone battery: Do not charge

Just bought a new phone for six months, the phone battery is not used. Later, consulting mobile phone engineers, found that it is usually their own phone to charge the "wrong position."
After a 90, I am a cell phone control. Daily life, whether it is watching the news, listening to music, or shopping, eating, etc., are inseparable from the phone. It can be said that smart phones are really "one of the greatest inventions of the 21st century."
After get off work every day, Xiao Bian will charge the phone, not only while charging while playing, but also charge the phone overnight. Until the next morning, go out to work, will unplug the charging line.
Therefore, think of want to go, only to understand that all night charging damage cell phone battery, so now the cell phone battery is not used
In general, smart phones use lithium batteries. Charger, the charger current flows from the USB port, usually "soldiers divided into two":
 1. Charge the battery current, for example, when the constant current 1A charge the battery;  2. To the phone inside the module (camera, LCD, RF, etc.) powered current.
First of all, will enter the trickle charge, then the  phone battery voltage is low to not boot, will trickle charge, charge current is small, the assembly damaged the battery.
Second, the charge will trickle charge into the constant current charge. At this point the current is constant, the charging current will reach 2A.
Finally, the final stage, into the constant voltage charge. 4.2V phone battery voltage is generally full, when the battery voltage reaches 4.15V close to full charge, the phone into constant voltage charge. The voltage is constant, the current gradually becomes smaller, the final current is zero, the voltage reaches 4.2V (or 4.21V depending on the model phone), the charge ends.
At the same time, I see online users answer, summed up several ways to affect the  phone battery life.
Over-discharge: cell phone in low power, the battery voltage is too low will automatically shut down. But if you restart, there is still power available. Automatic shutdown is a manufacturer of mobile phone battery protection mechanism, battery discharge will cause serious battery life damage, so the battery is too low, please charge.
Over-temperature: the phone battery temperature is too high will also affect the battery life. Frequent discharge of the battery will heat, in the actual use of the phone battery over-temperature, usually due to this cause. Therefore, you need to pay attention to the heat dissipation when playing a large game or running other power-consuming programs, and control the program running time.
Under-temperature: Lithium Battery When the battery temperature is below 0 degrees Celsius, charging is not allowed.
     Overcurrent: Using a high power charger to charge the battery can cause damage to the phone battery. However, manufacturers are now alarming when the charging current is too high. The worst case of overcurrent is short circuit. Short circuit may cause the battery to explode and burn, please do not try.

How to buy a power supply

How to buy a power supply


      Power supply is an integral part of computer equipment and has a huge impact on your computer. It is considered the most valuable component of any device and the most important component that can cause it. This article tells you what you need to pay attention to when purchasing a power supply.
1.Determine the wattage you need.
Use a power supply calculator web page or software to help determine your requirements. Even better is to find a review of a similar system that measures power consumption. As that consumption is measured at the wall, multiply by the review system's power supplies efficiency to get the output. Don't purchase a power supply just above your requirements unless you plan not to upgrade the system. Purchase a power supply that will take you through your next few upgrades.
2.Determine the robustness of the power supply.
How well does the power supply handle changes in current? Although not a guarantee, there's a strong correlation between weight and quality: bigger components equate to a more tolerant, reliable power supply. If you don't care about noise, an 80mm cooling fan in the traditional place on the rear of the power supply may offer better value.

3.Research which connectors you need.
Higher-end models may only provide a 24-pin connector, and lower-end models may provide just a 20-pin connector. Typically, most Pentium 4 and Athlon 64 CPU-based motherboards will require a 20-pin ATX connector, while newer motherboards require a 24-pin ATX connector. Also, most power supply will have both a 4-pin and 8-pin auxiliary 12V connector for motherboards, and only high-end power supply will have one or more 6-pin PCI-E connectors for video cards.
4.Check the number of rails.
Just as your house's fuse box includes both a large main breaker and a smaller circuit breaker per circuit to ensure the smaller-branch circuit wires do not overheat, high-capacity power supply divide their output into multiple "rails," each with a smaller current limit. The relevant safety standard requires a 20A limit, which is quite generous, given that the wires are smaller than those used in your house to carry 15A. A cheaper alternative is to provide just enough rails to total the overall capacity, which makes it difficult to use all of a power supply's capacity.

5.Look for power supply with high-efficiency ratings.
And, ones rated under load temperatures, not room temperatures. Anything 80% and above is good. At 83%, approximately 17% of the wattage is lost as heat. Therefore, a power supply that may be advertised as a 500W power supply, will actually be drawing almost 600W at the wall. Efficiency drops over time and during the life of the power supply. A year-old power supply is most likely not capable of producing the same amount of energy it once did when it was new.
6.Get a modular power supply.
It will help eliminate extra wires to get in the way of cooling. Ignore the claims by PC Power & Cooling that modular cables create more resistance due to corrosion of contacts. The additional resistance is negligible.
7.Compare the amperage of each voltage.
A power supply wattage rating isn't conducive to determining amperage at any specific voltage. All power supply will have a sticker with their rated amperage at each voltage level. This information should be provided when purchasing a power supply from an online vendor and visible on the unit's retail box.
      Do not neglect the power of the importance of choosing a good power supply is one of the prerequisites for your more joyful work.
