How Lithium-ion Laptop Batteries Work

wholesale hp laptop batteriesLithium-ion batteries are incredibly popular these days. You can find them in laptops, PDAs, cell phones and iPods. They’re so common because, pound for pound, they’re some of the most energetic rechargeable batteries available.

­ Lithium-ion batteries have also been in the news lately. That’s because these batteries have the ability to burst into flames occasionally. It’s not very common — just two or three battery packs per million have a problem — but when it happens, it’s extreme. In some situations, the failure rate can rise, and when that happens you end up with a worldwide battery recall that can cost manufacturers millions of dollars.

So the question is, what makes these batteries so energetic and so popular? How do they burst into flame? And is there anything you can do to prevent the problem or help your batteries last longer? In this article, we’ll answer these questions and more.

Lithium-ion batteries are popular because they have a number of important advantages over competing technologies:

  • They’re generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries.Here is a way to get a perspective on the energy density. A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery. A NiMH (nickel-metal hydride) battery pack can store perhaps 100 watt-hours per kilogram, although 60 to 70 watt-hours might be more typical. A lead-acid HP Business notebook 6710b battery can store only 25 watt-hours per kilogram. Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium-ion battery can handle. That’s a huge difference. batteries to suit your lifestyple – your best batteries online shop for HP laptop batteries, Toshiba laptop batteries, Dell laptop batteries, Asus laptop batteries, HP laptop AC adapters and Dell laptop AC adapters, all our notebook batteries and laptop power adapters are 100% satisfation guarantee and 100% brand new with 1 year warranty!
  • They hold their charge. A lithium-ion HP Pavilion dv9000 battery pack loses only about 5 percent of its charge per month, compared to a 20 percent loss per month for NiMH batteries.
  • They have no memory effect, which means that you do not have to completely discharge them before recharging, as with some other battery chemistries.
  • Lithium-ion batteries can handle hundreds of charge/discharge cycles.

That is not to say that lithium-ion batteries are flawless. They have a few disadvantages as well:

  • They start degrading as soon as they leave the factory. They will only last two or three years from the date of manufacture whether you use them or not.
  • They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would.
  • If you completely discharge a lithium-ion battery, it is ruined.
  • A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
  • There is a small chance that, if a lithium-ion battery pack fails, it will burst into flame.

Many of these characteristics can be understood by looking at the chemistry inside a lithium-ion cell. We’ll look at this next.

Top 5 More Handy Web Apps to Save You Time at Work

Web apps are a friend to all who mash the keyboard from nine to five. They live in the cloud, are accessible from any Internet connection and are great for chopping those mundane work tasks off at the knees.

We’ve previously highlighted a batch of Web apps that reduce the headaches and keystrokes associated with common tech chores, and after receiving some great feedback from readers, we thought it only right to hunt down a few more worthy bookmarkables.

See below for five more picks, and remember to leave your own time-saving Web ditties in the comments.

1. PrintFriendly

While we all strive to live in a paperless world, sometimes you’ve just got to ruthlessly murder some innocent trees. Does that make you a bad person? Probably.

The next time you need to print something from the Web, stop over at PrintFriendly first. It’s a ridiculously simple way to distill nearly any Web content down to a clean, ad-free document suitable for paper. And the best part? You can also generate beautiful PDFs that retain links and other formatting.

Goodbye, extra pages that are mostly empty space except for one banner ad and a URL at the bottom!

2. Vector Magic

Imagine this crazy scenario: The boss needs you to print up event flyers, but all she has is a tiny 100 pixel logo from the corporate website. (I warned you this was going to get crazy.)

Resizing this graphic with standard imaging software will render it pixelated and unprofessional. What you need is a vector asset—a mathematical representation of the logo that a graphic designer would use to scale the image at any size without sacrificing quality.

Vector Magic is a remarkable little app that translates standard Web images (JPG, GIF, PNG, etc.) into scalable vector art. We gave it a shot with’s logo, and the results were impressive and crisp. Mileage may vary depending on the complexity of the image, but even small, multicolored icons made great vectors in our testing. Photographs might get dicey, but it’s worth a shot.

Vector Magic packs a bit too much power to be totally free, but you get the first two vectors on the house, and a basic account is only $7.95 per month for unlimited use—well worth it, especially if you’re making a lot of PowerPoint presentations or laptop battery shop.

3. Dummy Image

Speaking of images, are you ever building a presentation or website and find yourself in need of a visual placeholder? You you’ve got a killer stock handshake photo coming, but right now you’re just getting your layout down, and the measurements need to be precise.

You could fire up ol’ MS Paint, slice out a 600 by 300 pixel box, color it red, save it to your computer, open PowerPoint, import the image, what did I name the image?, I swear I just saved the image, is it in My Pictures?, I can’t find the image, seriously where is this thing, restart MS Paint, ad infinitum.

Or, you could snag Dummy Image from your bookmarks bar, type in your dimensions and drag the graphic onto your slide.

I think we’re done here.

4. SimplyNoise

Let’s face it: Your coworkers are annoying and their incessant chatter makes it hard to focus on anything but cat pictures. Sure, Keith from accounting is a nice guy, but enough about Idol already, you’re a grown man for God’s sake.

We kindly recommend SimplyNoise, a white noise generator you can fire up with one click, should the office get rowdy during crunch time. In actuality, the app can generate three different kinds of static noise: white, pink, and brown. If you’re looking for warmer, less grating frequencies (like those found in a waterfall or an ocean), go with brown. The app even remembers your volume preferences.

Headphones sold separately.


If you’ve ever provided tech support over the phone to a coworker (or a friend or family member, for that matter), you’ve probably already killed yourself, so no need to read any further.

If you are alive, and foresee this being an issue in the future, you’ve got to check out It’s a dead-simple way to share screencasts with a tech-troubled colleague.

There’s no account to create, but you’ll need to provide your e-mail address so the app can share confirmations with you. Send a link to your coworker where he can record up to five minutes of his on-screen troubles. When he hits “stop,” the app uploads and processes the video, and shoots a private URL back to you. View the screencast almost instantly, diagnose the problem (likely that the printer was not, in fact, plugged in), and be heralded as office hero. The videos are lightweight, smooth and expire after a week.

Considering how frustrating it can be to reliably capture on-screen video for other purposes, the ease of this Web-based solution is pretty refreshing HZ9SD6KZHETV.

If you aren’t fist pumping at your desk right now over these life-changing websites, there’s probably little hope for you. Did we miss one that you can’t get through the day without? Share and share alike in the comments below.

Top 16 Best Ultrabooks for 2012

Ultrabooks feature Intel Core i3, i5 or i7 processors

Many of this year’s hottest new laptops are about one word: Ultrabooks.

The term Ultrabook is actually pure marketing, dreamt up by Intel for a new generation of portable PCs featuring its technology.

Like Centrino but unlike Viiv, it’s starting to stick as a catch-all term for thin and light laptops, or ultraportables as they’re sometimes classified.

The best way to think of an Ultrabook is a MacBook Air that isn’t made by Apple, a netbook that isn’t underpowered or a laptop that’s been on a crash diet. Ultrabooks all feature a Core i3, i5 or i7 processor, plus fast SSD storage and USB 3.0 connectivity.

According to Intel, Ultrabooks also have “ultra-capabilities” – security features, battery power, instant-on and quick standby. They’ll provide a lightweight alternative to tablet devices for people who just can’t work without a full QWERTY keyboard.

Intel has announced a massive $300m (£185m) fund to help develop Ultrabook hardware and software, and it’s confident that Ultrabooks will make up 40% of the market by 2012.

The first models are shipping with current generation Sandy Bridge Core processors, which will be replaced this year by a new generation of Ivy Bridge chips.

Intel set an initial price target of $999/£999 for Ultrabooks, though many have been more expensive – expect serious in-roads on the cheaper £600-£800 market this year.

But what’s the best Ultrabook to buy? Check out the best Ultrabooks we’ve reviewed, as well as some we got hands on with at CES 2012.

1. LG Z330 and Z430 Super Ultrabooks


LG z330


Rather than a tapered design, the chassis on the 13.3-inch LG Z330 Super Ultrabook is 14.7mm thick from front to back. It runs Windows 7 (for now) and has a bigger brother, the LG Z430, which comes with a 14-inch display. Why is it ‘Super’? Because LG says so.

2. Asus Zenbook UX31

Asus zenbook ux31


Asus has done a terrific job with the Zenbook’s design – even if you have to acknowledge that the designer took more than a sneaky glance at Apple’s ultraportable first.The 13-inch Zenbook is fantastic to look at. When closed, the wedge-shaped laptop measures 17mm at its thickest point and a mere 3mm at its thinnest.The same design thinking even stretches to the Intel Core and Windows 7 stickers. We wonder who it was that proposed they were silver and black – Intel? Asus? – but whoever did has made a difference.

3. Samsung Series 5 Ultra


Samsung series 5


Packing an Intel Core i5 processor, the Samsung Series 5 Ultra is small but perfectly formed. Available in 14-inch or 13-inch models, the 13 incher is 17.6mm at its fattest point, narrowing to 14mm.
It comes with a 128GB/256GB SSD or a 500GB hard drive (alongside a small 16GB flash drive) and incorporates an LED SuperBright screen. The only worry? Battery life is low at around three hours in our tests. Not to be confused with the Samsung Series 5 Chromebook. Which is definitely not an Ultrabook.

4. Samsung Series 9


The samsung series 9 ultrabook on show at ces 2012


While the original Series 9 was one of the world’s thinnest laptops, the new Samsung 9 Series Ultrabook is even thinner.

The design team has shaved off another 4mm, giving this 13-inch (1600 x 1200) laptop a waistline of only 12.9mm. Inside, a 1.7GHz Core i7 chip does all the hard work, ably assisted by up to 8GB of memory and SSD storage.

5. HP Folio 13


The hp folio 13 ultrabook on show at ces 2012


As the moniker suggests, the HP Folio 13 is yet another 13-inch Ultrabook. It’s not much of a looker and, at 18mm around the middle, it’s not the slimmest Ultrabook at CES.

But HP is claiming a 9-hour HP Elitebook 8530w Battery Life for the Folio 13, which will be ideal for regular mobile workers who value staying power over pretty design.

6. Lenovo IdeaPad U300S


Lenovo ideapad u300s review


Lenovo hasn’t obsessed over aesthetics, and this laptop is no Apple MacBook Air clone. It seems chunky next to the wafer-thin Asus Zenbook, which features a wedge-shaped design that tapers off to a thin, blade-like point.

The Lenovo IdeaPad U300S retains its 16mm thickness across the chassis, giving it the impression of being squat. The body is aluminium, and weighs 1.4kg, the same as the Acer Aspire S3, but much heavier than the Toshiba Portege Z830 and the Toshiba Satellite Z830-10U. If you’re looking for an ultrabook that will turn heads, you will most likely look elsewhere, but can the Lenovo IdeaPad U300S impress with power?

7. HP Envy 14 Spectre


The hp envy 14 spectre ultrabook on show at ces 2012


The HP Envy 14 Spectre is a little bigger than your average Ultrabook and a little fatter because of it. Intel specifies a sub- 18mm chassis for 13-inch models, but 14-inchers like this can bulk up to 21mm.

With a Core i5 (or i7) processor and 128GB HDD inside, HP claims a 9 hour battery life for the Spectre. And… that’s really the only appeal.

8. Dell XPS 13


The dell xps 13 ultrabook on show at ces 2012


The Dell XPS 13 might be a little late to the Ultrabook party, but it’s one of the prettiest portables we’ve seen.

Amazingly, Dell has squeezed an Intel Core i5 or i7 inside the trim chassis, along with 4GB of memory and a 128/256GB SSD. How thin is it? 6mm at its slimmest point.

9. Asus Zenbook UX21


Asus zenbook ux21


The Asus Zenbook UX21 is the first 11-inch ultrabook to hit the shelves. Of course, comparisons will be immediately drawn with the Apple MacBook Air, which is one of the best ultra-portable laptops money can buy, and these two 11-inch portables are very closely matched. The Asus Zenbook UX21 matches the Apple MacBook Air in every respect. It’s just as well-built, made out of a single piece of aluminium, just as light and oozes the same head-turning style and class that makes people cast admiring glances while you work in public. It also has the same Intel Core i5 low voltage 1.6GHz processor, and a 128GB solid state hard drive, which keeps the system really responsive and fast.

10. Lenovo IdeaPad U310 and U410


The lenovo ideapad u310 ultrabook on show at ces 2012


The Lenovo IdeaPad U310 has a distinctly MacBook Pro vibe to it but these Ultrabooks are expected to be at the cheaper end of the scale, around £600 or so. Packing a 13-inch display, the U310 tips the scales at 1.7kg and is squeezed into an aluminium chassis that’s 18mm thick.

A Core i5 chip is expected to provide the processing grunt, with the choice of a 64GB SSD or 500GB hard disk for storage. There’s also a U410, boasting a 14-inch display.

11. Toshiba Satellite Z830


Toshiba ultrabook


The Toshiba Satellite Z830-10U, priced at £999 in the UK (the US price isn’t yet available).

At its thickest point, the Satellite Z830-10U measures only 16mm across, but Toshiba has still packed in Sandy Bridge power and given us one of the best trackpads we’ve yet seen on an ultrabook. It’s not without niggles, however, and we found parts of the chassis to be inferior to stronger machines such as the Asus Zenbook.

It’s the lightest Ultrabook chassis we’ve yet seen, but also an excellent battery life, this could be the answer for frequent travellers who need a long-lasting machine full of performance for under £1,000.

12. Lenovo IdeaPad Yoga


The enticing lenovo ideapad yoga ultrabook on show at ces 2012


We’re loving the Lenovo IdeaPad Yoga. This flexible, foldable Ultrabook also converts into a 16.9mm thick tablet with a 13.1-inch (1600×900 pixel) touchscreen.

Running Windows 8 you get the best of all worlds – a QWERTY keyboard for heavy duty working and a tablet experience for after hours net sessions on the sofa. The downside? It probably won’t be cheap.

13 Acer Aspire S3


The 13.3-inch Acer Aspire S3-951 is an appealing prospect for regular travellers. The Intel Core i7 2637M version we tested is priced at £900 in the UK and costs $1300 in the US (where it has the more specific name of Acer Aspire S3-951-6432), which is enticing, considering the impressive specs list.

A less powerful Core i5 model can be bought for £700 in the UK, while in the US there are three cheaper Core i5 machines, two of which cost $900, while one retails at $1199.

14. The Intel Nikiski concept


The intriguing intel nikiski concept laptop has a dual purpose glass touch panel


While not technically an Ultrabook, Intel tells us that a Ultrabook version of the oddball Nikiski is on the cards for later this year.

What makes it stand out is the glass touch pad that turns into a touchscreen layer to enable you to browse a slimline view of key information such as new emails.

15. Acer Aspire S5


The acer aspire s5 ultrabook on show at ces 2012


Thin (15mm) and light (1.35kg), the new Acer Aspire S5 isn’t much of a design departure from the older Acer Aspire S3.

But it takes advantage of its Ultrabook DNA with a 13.3-inch display, Thunderbolt technology, SSD storage and a fast (but as yet unspecified) Intel CPU. Are we excited? Meh.

16. Novatech nFinity 2367 Plus


Novatech Nfinity


The Novatech nFinity 2367 Plus is the first Ultrabook we’ve seen that isn’t from an established, global computer company. That isn’t to say Novatech is small. The British firm has been selling both components and customised PCs for a while, and in keeping with tradition, there’s plenty of choice with its Ultrabook range, with the option of an Intel Core i3, i5 or i7 processor, and varying quantities of storage and memory. The Core i3 Novatech nFinity 2367 Plus model that we were sent is priced at just £625, and comes with 4GB of memory, a 128GB SSD and Windows 7.

Australia’s top 5 laptops based on battery life

Looking for a laptop that can run for most of the day without a recharge?

The boffins at technology site CNET Australia reckon that HP‘s Folio 13 Ultrabook should be top of your list, as it gallops along for almost six and a half hours on a single tank of juice.

Two more HP laptops follow the Folio – the Envy Spectre 14 and the Pavilion dm1 – before the field widens to include models from Lenovo, Dell, Asus and Toshiba.

Apple’s MacBook Air makes a surprisingly late appearance in the field, with the 13 inch model in twelfth place based on a battery life of 4 hours 43 minutes.

CNET’s aptly-named Laptops with long battery life 2012 report assesses the battery life of each notebook reviewed by the site using a pair of real-world tests.

The heavy-duty test sees the laptop playing a HD video with both screen brightness and volume wound up to full. A light HP nc6000 notebook battery test trims the screen brightness to 40 per cent and visits three different websites every 20 seconds.

CNET Australia reviews editor Craig Simms says this snapshot of the current market will be continuously updated as new laptops are released.

It can be difficult to trust a laptop maker’s own figures on battery life because “things will change depending on usage patterns” as well as how the manufacturer chooses to measure battery life, says Simms.

“Some will quote incredibly light-use battery benchmarks with most things turned off and the screen set to the lowest brightness — a totally unrealistic use scenario” he tells Australian Business Traveller. “Others, such as Samsung, tend to be more honest with their Dell Inspiron n5010 battery life estimates, using video playback stats instead.”

And while Ultrabooks are helping to set new benchmarks for battery life, Simms says he would be disappointed “if a 13 inch ultrabook didn’t hit at least four and a half hours of light use with screen brightness around 40%. The better ones can exceed six hours.”

A raft of advances in laptop technology is also helping drive battery life towards true all-day capability.

“Since the MacBook Air, quite a few laptops have (adopted) non-user removable batteries, allowing for custom shapes that allow the manufacturer to maximise battery storage for their specific laptop” Simms explains.

“Intel’s ultra-low voltage processors have made quite an impact on power draw, and yet only sacrifice minimally on performance, while on more powerful laptops, graphics switching technology that allows AMD and Nvidia graphics to switch to less power-hungry Intel graphics when the more powerful cards aren’t needed helps the laptop to save on Dell inspiron e1505 battery.”

Simms also sees the widespread use of LED back lighting in displays, “automatically dimming the screen after a period of disuse and smart dimming of screens in different light situations” as helping extend battery life.

Other Ultrabook-type trends such as dropping CD/DVD drives and replacing spinning mechanical hard disks with solid-state drives have also done their part to eke out more hours between recharges.


How to Sync iPad To a New Computer – iPad Usage Tips by

Want to Sync iPad to a new computer? When you get a new computer, it can be a bit of a downer to plug your iPhone, iPad or iPod touch into it and be told that you’ll have to erase it and start again, all because it’s synced to a different iTunes library. Don’t despair, because there’s a away to avoid wiping your precious device provided you still have access to the computer you’ve been syncing it to. It can seem a bit fiddly to do, but it’s a lot easier than having to start from scratch with a clean device.

The secret lies in the fact that your device syncs to a specific iTunes library, not a laptop computer. So the trick is to move your library from your old computer to the new one, and your iPad won’t know the difference!

If you’ve been using the default settings in iTunes (that is, letting it organize your media for you, as opposed to storing it elsewhere on your computer or on an external drive), what we’re going to do here should transfer your actual media files across, too. If you’ve been organizing your files in a different way, you’ll need to be sure to move those separately.

You need access to your old and new computers and a way of transferring a large amount of data between them. The fastest would be over a local Ethernet network, bit if the machines aren’t linked, an external hard drive or USB stick will do the job. We’ll show you below how to find out how much data you’re going to need to move.

Sync Your Device

Plug your iPhone, iPad or iPhone touch into your old computer for the last time and open iTunes. Right-click its name under Devices and choose sync. Once that’s done, unplug your device and lay it to one side for now.

Find The Folder

Go to Edit> Preferences (Windows) or iTunes> Preferences (Mac). Click Advanced; we’re interested in where it says ‘iTunes Media folder location’. The folder we need to copy is called iTunes (not iTunes Media).

Size Matters

Open Finder or Windows Explorer and browse to the location of the iTunes folder (in our case, that’s in C:/Users/YourFolder, and so on). Right – click the iTunes folder and choose Get info or properties to find out its size.

Copy The Folder

Armed with the size figure, get hold of a hard drive or USB stick big enough to fit it on. Copy the iTunes folder to it. Once everything’s across, disconnect the storage from your old computer and hook it up the new one.

Find The iTunes Folder

On your new machine, find the location of the iTunes folder as you did in step 2, then close iTunes. If you’ve got any media on this computer already, move the existing iTunes folder elsewhere to avoid overwriting it.

Open iTunes

Now copy the iTunes folder from your storage device into the exact place that we established in step 5. Once it’s copied, open iTunes. All being well, the music and apps from your old computer will be waiting for you.

Settings Tweak

If you stored media elsewhere on your old computer, add it to iTunes on the new one. In Preferences, click Devices and check the box to prevent automatic syncing, ensuring your device doesn’t get wiped when you plug it in.

Plug in Your Device

Now connect your device to the new computer and click the Apps tab. The sync box will be checked, indicating things are working well so far. Don’t sync yet, but right-click the iOS device in the left pane and choose Back-Up.


If you’d synced media automatically on your old computer, make sure it’s all present under Library on the new one, because when you sync, anything that’s missing will be wiped from your iOS device. If it’s all there, sync away!

Back up Your Computer

Now that everything’s transferred to your new computer and it’s syncing with your iPhone, iPad or iPod touch, it’s a good time to back up the Mac or PC. In Mac OS X, click the Time Machine menu and choose Back Up Now.

And in Windows…

Create System Restore Point by right-clicking Computer, choosing Properties and then clicking System Protection on the left. Make sure Protection’s set to On for your hard drive, then click Create….to get started.

Deauthorise Old Machine

You can authorise five computers to use your iTunes account, so deauthorising old machines is wise. Open iTunes, click Store> De-authorize This Computer….., type in your Apple ID and password and click Deauthorize.

Asus Eee Pad Transformer is a winner

In case you’ve been living under a rock, 2011 is the year of the tablets. Apple’s iPad burst unto the scene in early 2010 and since then other tech giants have been positioning themselves to take advantage of this new segment of mobile computing. A tablet specific version of Android is now available and just as in the smartphone segment a plethora of android powered tablets are being released or are on the horizon, the Motorola Xoom, Samsung Galaxy tabs and Acer Iconia being 3 of at least 7 I can remember off the top of my head. There is one contender though that I am most excited about and it’s called the ASUS Eee Pad Transformer.

Modern Mobile Device

It’s a tablet, it’s a netbook, it’s mobile, it’s powerful, it’s modern, it’s new and it’s different but familiar. That is how I describe the ASUS Eee Pad Transformer. As an Android user and a consumer on the brink of buying a preferably android-powered tablet my allegiance has bounced around with just about every Android tablet revelation.

The Asus Eee Pad Transformer with it’s tablet form factor, Android brain, expansion slots, usb support, HDMI port and all important keypad and battery extending add-on fits all my needs and is unique (for now) and very functional when I think about my needs as a blogger, soon-to-be traveler and techie on the go who is a weirdo that hates bulky laptops. Below is a video walk-through if ASUS’s new tablet.

Top Tips for Longer-Lasting Laptop Batteries

Hardware budgets are feeling the pinch of our tepid economy, and many companies are making employees use their laptops longer. If you are starting to tell your folks to keep plugging along with their laptops for four or five years instead of just three, you might be running into an unexpected expense: dead laptop batteries.

Well, to be fair, your laptop’s batteries probably aren’t completely dead. But since Lithium Ion batteries tend to lose about 20% of their capacity each year, a typical three-year-old laptop might only get about an hour or so on a charge, which might not even get your folks through an entire meeting. Here are four simple tips to forestall the day that you need to replace those batteries:

Keep it cool. Heat is the primary killer of batteries. Tell your employees to be careful not to let their laptops overheat. One common way that happens is packing a running laptop into a backpack or briefcase. If the laptop fails to go to sleep (and let’s face it — sleep glitches are common), then the laptop can get crazy hot in an enclosed space. You can almost smell the loss of notebook battery longevity.

Recondition your battery regularly. Most laptop manufacturers (except Apple) don’t generally tell you about this, but a simple process known as reconditioning (or occasionally, recalibrating) can breathe new life into your laptop battery and add capacity back. To do that, turn off your screen saver and any other power management tools which put your PC to sleep. Fully charge the laptop, and then let it run all the way down — right until it powers down due to lack of juice. Then charge it back up again and restore your power management stuff. Do this every few months (such as three times a year).

Dell 312-0393 Battery, Brand New 4400mAh only AU$87.30

Toshiba PA3357U-1BRL Laptop Battery, Brand New 4400mAh only AU$73.33

Remove it when you’re not using it. When you leave your laptop plugged in at your desk all day every day, the battery never gets a chance to discharge and recharge — which is critical to its long-term health. Thankfully, there’s a simple solution: Remove the battery. As long as your laptop is connected to AC adapter, the battery isn’t necessary; it’ll run without it. Just remember to pop it back in before you take your laptop on the go.

Start with a super-sized battery. When you purchase your next round of laptops, upgrade to the extended-life battery. Not only will it give you significantly longer runtime to start with — great for road warriors and anyone else who works away from the office a lot — but the inevitable loss of laptop battery life will have a less pronounced effect. The added cost of the larger batteries is worth the investment, because they end up lasting significantly longer.
