This level minimizes age-related loss of capacity but the battery lasts very functioning with some self-discharge.While the open terminal voltage of nickel-based batteries can be used to quantify levels of SoC voltage suitable for fuel cell lithium-ion batteries. However, the differences being in electrochemistry electrodes and electrolyte between the producers, the voltage profile slightly. An SoC is 50% reads 3.8V, 40% 3,75 V. Store lithium-ion batteries for the open circuit voltage of 3,75-3.80 V. Leave the battery after a rest 90 minutes before reading.

Best Dell Laptops

November 27, 2009 By: lilybird Category: Desktop and Laptop

Laptops have since long become a necessity than being a luxury. More and more people are waking up to the convenience and comfort of using a laptop over that of using a desktop PC and the laptop industry is growing by leaps and bounds. The laptops not only provide portability but can be used as a desktop computer too when not being on the move. New innovations and developments are making them a more sought after choice by the day and they are becoming more and more advanced in technology, multifarious in features and swanky plus compact in design.

Dell has been one of the market leaders for all kinds of computers for a long time now. The year 2008 Q1 market share of Dell notebooks was 15.1% that put it on the second position of most sold laptops behind only HP. It is obvious then that Dell is a trusted name not only in desktops but also in laptops and has an established market position.

Latest in Dell

When I talk about the latest in Dell laptop I have talk about the new ‘Latitude E6400 XFR’ rugged laptop. Dell is breaking all benchmarks with this new release that is meant for some real rough and tough usage. Sophisticated electronics like laptops were always difficult to use in dusty and harsh conditions however the Latitude E6400 XFR is going to change all norms regarding the same.

The rugged notebook is meant for military and other such professionals who need field operations on their notebooks. It features a Ballistic Armor Protection System that gives twice the impact strength of magnesium alloy making the Notebook extremely sturdy. It has 25% more drop specification than other notebooks of its class, it can handle extreme temperatures, it is scratch resistant, and is equipped with Primo Seal technology to give increased protection from dust and liquid spills. Now if that starts sounding like a description of some latest weapon up on the military block to you then you’d be surprised to hear that the E6400 XFR is not just sturdy and rugged but also sophisticated enough to have a touch screen and other hip features of other modern notebooks! If that sounds amazing to you then let me also add that this is just a sample to taste what all this latest gizmo from Dell has to offer and there is lot more to it that will make you awestruck.

Other than this much talked about offering by Dell, there are a few other launches by the giant too. Like the new Inspiron 15 which features a large LCD screen, up to 4GB of RAM and 320GB of hard disk, Blu-ray, face recognition and a built in webcam; or the Studio 1555 that is an upgraded version of the Studio 15 series with a new LED backlit, wide screen, large storage capacity, and WiFi etc.

Other than what has already been launched, there is some other cool magic waiting up Dell’s sleeve to captivate us. Dell recently gave a glimpse of the much hyped ‘Adamo’ which is supposed to be an attempt into the luxury electronics and also a competitor to the Macbook. It has a striking design and bold yet elegant looks. What’s more, the ‘Adamo’ is even thinner than the Macbook! It is coming to us in two opposite avatars- black and white and is truly beholding. Only wish we could lay our hands on it sooner than soon!

Why Dell?

Other than being the major market holder for computers Dell is one of the most innovative computer manufacturers around. The USP of Dell however has been a reasonable price for a reliable, quality product and this is what has been making it lead the market for long. You not only get the latest innovations and updated technology with Dell computers but also get them in a great price. More so, if a large chunk of the market trusts a company, there has to be immense credibility behind it.

Today Dell is a common name in the country. You can find a Dell dealer almost every where. You can choose a laptop to suit your requirements based on storage, kind of usage and connectivity features you would require. A good option would also be shopping over the internet. There are a number of online shopping portals these days that offer convenient shopping and safe home delivery. The good thing about online shopping is that you can even manage quite amazing discounted rates and crack some cheap deals to procure your favorite notebook. So, go make magic with Dell!

7 Tutorial On How To Select The Perfect Laptop

October 23, 2009 By: lilybird Category: Desktop and Laptop

7 Tips On How To Select The Best Laptop For You:

Tip 1: Know The Purpose Of Your Laptop. In other words, why are you buying a laptop? This is extremely important to know and admit to yourself because different purposes favor different aspects in a laptop. Are you a gamer? Then your going to want a great graphics card and a good amount of RAM (Random Access Memory). Are you a casual at-home user? Then you will want a great battery-life along with some Processor Speed (Ghz). It’s very important to know what you need for your dream laptop.

Tip 2: Choose a Computer Look That fits your style. The best laptop best laptop for you is the one that is going to make you squirm by just looking at it. You should pick a color that you either love or a color that fits your personality. Professionals who use there computer for work and profit usually prefer white or gray. Experts who are serious and enjoy showing off their knowledge tend to go for black. More Unique users branch out and purchase red, green, or blue laptops. Also, are you after a laptop that is paper thin? Do you prefer a big screen? These are things you need to know before hand so you will know the perfect laptop the instant you see it. Check out my webpage (in the resource box) for way more information on this topic.

Tip 3: Know your price range. You can find the right computer for you much faster if you use advanced searches and enter in a price range. This will keep results off the page that you instantly disregard because they are either way out of your budget, or look way to cheap without good specs. How do you know your price range? Just ask yourself, “If I saw my dream laptop, with every attribute I wanted and more, would I pay $700 for it. What about $750. $800?” You get the point. Also, tell yourself your not going to jump on any deals that are WAY to good to be true. Obviously, your not going to get your dream laptop for $150. So don’t aim for it. A really good way to get an awesome laptop for a much cheaper price is to build it yourself!

Tip 4: Aim For Decent Internal System Aspects. Like I said before, different purposes for a computer lead to different main aspects. But, overall you don’t want anything to be horrible even if the rest is great. For example, you are getting 3 GB of RAM, a whopping 200 GB of Hard Disk Space, and for a great price, sounds great! But wait, the processor speed is only .5 Ghz, slow as a snail. Unfortunately, one major drawback like this can prevent us from being pleased with the laptop. Click Here for a great free table that shows you my personal opinions for good aspects.

Tip 5: Microsoft Windows or Apple MAC? This is a VERY big decision that you have to make. It all depends on your style and how you want your files organized. Windows gives you more of a decision on what security settings to use and where your files are placed. MAC can be very handy though because it organizes your files and folders for you. Which is for who? It depends on how much you know. If you know a lot about computers you will probably prefer Windows, where you can customize it to your style. If you don’t know much and don’t have a clue what your doing, then MAC is for you because its very hands off and keeps you from accessing your dangerous or program files. One more pro for MAC, Apple creates its own products for its products. What do I mean? Anything, and I mean anything, that is created by Apple for computers will work on your computer. Check out my website for way more free information on operating systems.

Tip 6: Get a Laptop that has that perfect “feel” to it. What am I talking about? Certain laptops may have something to them that will utterly annoy you forever. Examples:A screechy keyboard, USB ports in the back of the computer, an unresponsive mouse pad, etc. Look online to find information about other users of the laptop who had “annoyances,” or, better yet, ask if you can try using the laptop for a test run before actually purchasing it. The goal is to find a laptop where everything is right where you want it, and the feel to everything is great!

Tip 7: Make sure you are getting everything you think you are getting. Buying a laptop off Ebay, Craigslist, or any other place that sells used or refurbished laptops? Then MAKE SURE to check contents of the package before purchasing. Some people will scam you and send you a laptop that has no power cord! Even some stores these days sell new laptops that have no wireless card (used for connecting to the internet wirelessly)! It is better safe than sorry, don’t get cheated out of your money!
