Teach you how to choose a good battery

Mobility is different from the notebook computer is an important feature of desktop. It is also because of this feature, make laptop battery in casual maintain between assume the burden of moving image notebook. Although with the development of technology notebook product performance has improved. But as a mobile as the main characteristics of electronic products, a lack of long battery life ability laptop, is impossible to take on the long time mobile office and entertainment needs. And without battery power to help laptops, Anytime, Anywhere "its" the advantage is also mentioned.

Although laptops with cabinet fuselage, more and more powerful functions, had occupied the computer market about 40% of the share. And in between white-collar personage with laptops but also a developing as a fashion. But most users to know only stay notebook products in performance, appearance, and portability and other aspects. But for this deeply like the accessories battery but knew little. And for how to correct the choose and buy, use and protect the batteries are not know more. And this paper types, from the notebook batteries use and structure, four aspects of choose and buy for everybody introduction about all aspects of laptop batteries. Hope for laptop users understand the battery has certain help.

Cell types

Current main battery including nickel cadmium battery (NiCd), NiMH batteries (NiMH) and lithium Ion battery (Li - IO. Because of its different characteristics so they are different mobile equipment used. Of the three ni-cd battery and nimh batteries due to also adopted nickel as cathode materials so their basic characteristics, its working voltage are the same for 1.2 v. due to launch time earlier (1963 successfully developed) plus characteristics, ni-cd battery shortage has been fully eliminated. At present, only in a few less demanding for power equipment can see the figure. Ni-mh battery is nickel cadmium battery an improved product. Because the hydrogen peroxide as battery anode material, so the nimh batteries have greater unit volume energy density. That is to say, in the same volume than nimh batteries have under greater nickel cadmium battery capacity. Except in volume and density advantage on the nimh batteries outside, durable sex is relatively has much improved. Normally the rechargeable nimh batteries in 600 times or more times common, some good quality product charge-discharge can reach 1200 times. This makes a nimh batteries in three forms of "longevity" was the most. And because the nimh batteries in production won't produce harmful substances, plus scrap nimh batteries can be reused. So ni-mh battery is a kind of very environmentally friendly products.

Although some characteristics nimh batteries on very good. For example has a long cycle count. But as a result of current mobile equipment for battery capacity and volume requirements are mounting up, so nimh batteries was soon replaced by lithium-ion batteries. Here to remind everybody is, we're talking here about a lithium-ion battery. But some users usually put the battery referred to as lithium batteries. In fact at old lithium-ion batteries has always been there. Because of its internal adopted more lively lithium metallization and content as the carrier, so often appear combustion, burst. And it is this in use unsafe made early lithium battery soon eliminated. And we see now are of lithium-ion battery is an improved product. It in the early days of the basis of lithium battery joined the can restrain the lithium elements in the materials, so active use on more security.

According to the current lithium ion batteries with lithium compounds within divided into: lithium battery, lithium - - polyethylene lithium batteries, manganese dioxide - and sulfur carbonyl chlorides battery and lithium sulfur dioxide battery -. No matter what form of lithium ion battery its characteristics are similar. Lithium ion battery power is about the size of the nimh batteries with volume 1.5 times plus lithium ion battery unit weight than nimh batteries light many. So whether from capacity, volume or weight is more suitable for lithium ion battery now in weight and volume on the frivolous tends to mobile device. Lithium ion battery discharging voltage is 3.6 ~ 3.7 V, this is almost nickel cadmium/three times of nimh batteries. Due to have this one character, make in the output voltage under the condition of the same number of microroughness single lithium batteries can reduce one-third, thus making the battery after molding weight and reduced volume. And lithium ion battery no obvious memory effects, so you don't need to periodically charge-discharge management. So using on more convenient.

Lithium ion battery according to the different shape can be divided into cylindrical and rectangle. Cylindrical of lithium-ion battery and we usually see # 5, 7 alkaline batteries, and a rectangle almost product is some CD players is used on "gum" battery. And because each notebook input voltage and battery capacity difference. These lithium ion battery batteries commonly used in the form of a fixed unit package. Plus some necessary charge-discharge protection circuit is formed what we now see shapes notebook batteries. Take our common 108,000 V 4000mAH notebook battery pack to say. It's five section single capacity for 2000mAH of lithium-ion battery, using three and even two series that constitute. And lithium ion battery according to different models have different amounts of products. This is formed we saw different capacity of different voltage notebook battery pack.

Although at present the mainstream notebook USES lithium ion batteries, acer aspire 5920g battery and lithium ion battery and high capacity, small volume, light weight, and no memory effect characteristic. But because the rechargeable lithium ion battery relatively short put times, only 300 to 500 times or so. So in maintenance as well as using also need to be aware of some problems. The following three is when users in the use of battery problems needing attention.

A new laptop batteries, purchased should batteries 8 hours and then utterly exhausted, so repeat 3 times in order to allow the battery to achieve optimal use state. Although notebook battery module has the factory when after activation. But in order to make a battery into the groove, the user must want the battery to a certain extent charge-discharge will awaken the full capacity battery. Here, a full of new battery charge is for this purpose.

Second, when used in notebook, if often time without use the battery will take from the machine down battery in dry shade preservation. As laptop battery charger number is limited, lithium ion battery is about 500 times or so. Lithium ion batteries due to the not in use situation also lose power. So will the battery cancel save can avoid battery charging repeatedly.

3: regular charging and discharging. Even without memory effect of lithium-ion battery exist certain inert effect, long time don't use can make lithium-ion lose activity, needs to be activated. Therefore, if long time (3 weeks or longer) don't use computer or find battery charging and discharging time shorten, should make the battery to completely discharge recharging, generally after each month full charge at least 1 times. A: how to choose a good battery

Understand the current mainstream laptop batteries and how to maintain the structure of choose and buy, so users in the battery products should pay attention to what problem? Because at present most laptop with standard only a piece of battery, the battery is usually sold with the machine also. And we know that even the same specification using the same material battery will also according to the different and show made of individual differences. Even businessmen allows users to select battery, users will not know the battery should be the actual use effect better give up. In this case, buying notebooks how to understand the specifications of the products is equipped with battery and actual condition became had to consider the question. Below we on how to distinguish a battery the actual use of the state to provide you two small skills. Hope to everyone choose battery has certain help.

A, through products bringing battery management software to understand the battery status

General some international a brand notebook products are in its incidental software provides a management in battery tool. This tool by reading the intelligent control chip internal battery to see such as using time, battery design capacity, the actual capacity and cycle count and other information. Through its users can learn about some labels in battery surface invisible to the information. Such a paragraph of choose and buy actual performance better product has greatly help.

Second, BatteryMon software use actual use time determination battery

Although we can through software see some laptop battery of relevant information, but because the actual consumption is different, machine for the actual use of the battery effect also is cruising time we don't know but equally. If users don't want to take too long Batttery Mark or use MobilMark these professional battery test software running of the battery completely that underneath this side of BatteryMon software is very useful. This software is through determination of actual use batteries in the actual consumption to see the actual use of the battery time. When users unplug next power source and click Start button, began after a few Mon is recorded Battery declines curve, about 2 ~ 10 minutes will generally depicted power declining graphs, then you can choose a Rate in Comparison with your actual power curve of the standard curve near slope, so that they can generally know how much time will be able to use the Battery. But need explanation is a few Mon and can't control your notebook PC power consumption status, so the result of a few Mon largely depends on your machine current CPU speed. Screen brightness, system work load and whether use cd-rom. So in the use of this software test battery, the user is best actual operating the computer, such as open some document, install some programs or watching some CDS/VCD/DVD movies. And for the new notebook battery suggested user testing time is 15 to 20 minutes. Such ability more accurate determination of the actual use of the battery time. Now is no longer simple notebook of mobile office appliance now, more and more functional endowed with notebooks new vitality. With the increasingly instead of desktop notebook trend, many game enthusiasts and what kind of expectations? On the one hand, we hope can enjoy the frivolous and mobile notebook, on the other hand we don't want to miss those who let us stirring happiness game. After all, now play games with notebooks are not too cool, because the price of the factors, the game model is not the average person laptop can afford. The hardware of the factors, mobile graphics performance relative desktops or sent a class, a market factors, not how many manufacturers are willing to take bets on him, in game notebooks pressure without much businesses willing to bet on games notebook body, have ideas, the concept of factors of mainstream or notebook should be frivolous primarily. But according to the current situation, the situation will soon be changed, because there are many manufacturers foray into consumer notebook market (fashion type, type, etc), and game play by more and more laptop manufacturer of devotion, DELL, HP now have some giant follow-up, Toshiba, as for some overseas other factories many early, only those products started with our estimates for it (price factor). So we game gens expect soon can use this originally cruise game kingdom. Super gaming notebook has appeared many:

HP free market ZD7000 currently game notebooks number most concerned the DELL Inspiron XPS, HP free after the ZD7000, and launched to combat the above two products of Toshiba's do - S520. And there's more recent report the ABS company launched super power game Mayhem G1, but notebooks front several products estimates will soon appear in all of our current, and ABS products estimate we basically impossible to close appreciated the, in domestic haven't agent. Toshiba do S520 since is super game - notebook, so configuration must be not underestimated it. So, the fact is that a few super game configuration of the laptop, estimates that even is a desktop and many are place, they all deficits by GHz P4 3.0 is more processor (including DELL Inspiron XPS is adopted Pentium4 800MHz FSB 3.4 GHz processor, HP ZD7000 also has 3.2 G. This also no wonder, games, and other high-performance notebook demand CPU difficult to meet.) , high-performance graphics (DELL Inspiron independent Mobility Radeon 9700 by XPS ATi graphics chip, 128MB memory DDR independently by S520; Toshiba do - NVIDA GeForce FX Go 64MB independent 52 graphics chips, memory DDR ZD7000 using NVidia GeForce; HP Go5600, 128MB independent DDR FX series.in Mayhem G1 using video memory; ABS ATi Mobility Radeon graphics chip, 128 MB 9600 independent video memory), high-capacity DDR memory (are the 1024MBDDR333 or DDR400), hard disk are also 7200RPM, besides these notebooks are also have wireless card, is ready for online games. These super notebook really let us daunting?? Configuration and performance scary, price scary (the cheapest also want 1799 dollars), it seems we have to wait another end time to just go. Recent hot ABS Mayhem G1 currently on the market the game was too expensive for notebook market demand consideration, before the basic can't put too much notebook manufacturers in the game, the main body of lies in notebooks on game dares say cost performance was good notebook can really high, and the high-end notebook on consumption is not gamers. As the above several super gaming notebook is really let people like, but like also heart uncomfortable ah. Game on the laptop market lies in the ability to buy demand, so hard to mass production so as to reduce cost; Second, demand shortage brought the insufficient competition to everybody, difficulty in forming the favorable price changes; The third is hardware performance more demanding and difficult to reduce the cost of physics brought; Finally just haven't game to the trend of the laptop, when the game (notebooks became tide again your will also good estimate of people buy. The price of those super game notebooks for all of us is really high, but their game performance and we have to praise, and we continue to watched and looking forward to their foray into China and slashed prices. But there seems to be more practical perhaps still expect a simplified version of appear, there is more can the game in notebooks for us to choose. The market those games now claims are basically too upscale notebooks, not suitable for most gamers buy.

DELL Inspiron XPS its price tag of $2899 independent video card more and more although notebooks those few super above all wanted to have game notebooks, but actually work on a few, however we estimated the game to ask for so really high-performance notebook? In fact for the average game, such as CS, mainly still CPU demand is higher, so if your notebook is G + processor, memory card, and independence, not less than 32M word play generally games are enough. So the game enthusiasts if buy notebooks, if want to play games personal recommendation still had better choose the type (currently independent graphics card of the mainstream notebook MOBILITY RADEON 7,500 of a ATI MOBILITY RADEON hd 9,000, MOBILITY, MOBILITY RADEON hd RADEON 9200, GeForce2 9600 and nVIDIA 'series, GeForce4 Go series, GeForce FX Go series, etc.). And in fact the market because of the display card type independently of the video you are demanding more, many models price is not so scary, everybody's choice is still a very wide. Such as DELL Inspiron ATI Mobility Radeon hd 600m (9,000 graphics chips, match with 32M DDR memory), the independent ATI Mobility Radeon hd E3500 (east 9,000 graphics chips, match with 32M DDR memory), amoi independent Mobility Radeon 9600 V7 (ATI graphics chip, match with 64M DDR memory) etc. laptop battery Independence If you are not that hardcore players, so these with separate graphics notebook also is a kind of our very good choice. Soon we can enjoy the game notebooks

Beijing Oriental E3500 game of notebooks listed will with more and more of the manufacturer devoted and soon appear; The game of the cuts will notebooks with the various forms of reducing the cost and gradually realize; The game will be with the trend of the laptop and the ratio of appeared gradually emerged; The game is no longer the laptop consumption will enjoy unattainable, the near future our game life will probably through the notebook realized. This all sounds really good, and in fact they did not far away the come true. The situation is mainly high-performance game price is too high, a large number of notebooks game players generally feel or lovers or to play games or don't use notebooks, these are just play the game enjoyment hinder our notebooks, which is key to the research and development with the technology progress soon will is not a problem, and we soon may enjoy mobile version of the game anymore.
