Laptop Battery Doesn’t Last As Long As It Used To,What Can You Do ?

Laptop batteries do indeed get weaker and have limited lifespans (generally under three years but newer laptop batteries are coming out that last much longer). You don't say how old your laptop battery is, but here are a few resources and tips to give it a checkup.

Testing and Monitoring Your Battery: Windows

There is Dell LATITUDE D610 laptop battery laptop battery with high quality at electronic-parts.com.au.

Previously mentioned Battery Eater is a free Windows utility that can do a full load test on your battery and let you know how long it should last. If there's a discrepancy between what you're seeing from the program and actual experience, check out ways to extend your battery life (see below).

Some Lifehacker readers have recommended instead BatteryBar, which comes in a free and pro version and lives in your system taskbar. It offers a visual display of your remaining battery life and keeps a history of your battery charge and discharge times so you can better gauge how long your battery will last.

Testing and Monitoring Your Battery: Mac

If you're using a Mac, we've described a tip before for using the built-in System Profiler (under Applications > Utilities) and go to "About this Mac" where you'll find information about the battery's health in the Power section.

If you want to use a software program for monitoring your Mac laptop's battery health, we've recommended iStat Menus previously. The application provides detailed battery state info as well as advanced information for other OS X system properties.

What to Look For

6600.00 mAh,li-ion Dell INSPIRON 1521 battery is quite cheap and brand new.

If your laptop battery only holds about 50% try conditioning or recalibrating the battery (below). If it's 25% or less, consider buying a new one. Of course, also take age into account—a really old laptop battery will just need replacing.

Recalibrating Your Laptop Battery

Brand new HP PAVILION DV2000 batteries worth your choice!

Calibrating or recalibrating your laptop battery may recondition your battery to hold more charge again. We've described the process previously, which involves basically putting your laptop to sleep and fully charging it, then letting the battery fully drain again. Then charge your battery up to full again. Apple recommends doing this calibration when you first get your laptop and then every few months thereafter.

Windows users can use a tool called BatteryCare, which not only monitors your discharge cycles but can also recommend when to calibrate your battery. For Mac users, Watts ($6.95) is a similar application with a reminder for when to calibrate, Growl notifications, and calibration assistance.

That's all well and good, you're probably thinking, but after monitoring your battery life, if you're still having poor running times and your laptop battery looks healthy, there are some things you can do to maximize your battery life: switch to a power saver or balanced power plan, decrease the screen brightness, keep your laptop cool, and use hibernate mode. For more detailed descriptions of these suggestions and other tips, see our guide to extending your battery life. Good luck!

Care Power Tools Battery

Cordless power tools are becoming more mainstream and are taking on a more important role in woodworking. At the same time, the individuals who depend on battery systems to keep billions of dollars worth of remote controlled aircraft in the sky have developed power tool MAKITA 6093D battery maintenance into a science and are generally far past the mystery stage.

So keeping in mind that a cordless tool doesn't come with any of the sophisticated peak chargers and monitoring equipment used with aircraft, and that most power tools come with two sets of batteries, what are some general guidelines that should be followed in order to maximize the performance and longevity of the MAKITA 1822 power tool battery pack?

1. Don't leave them on charge continiously. Use an appliance timer to put in 1 hr a day. If you run one down just set the timer to charge for 16 hrs. I keep all my cordless products plugged into a power strip that is plugged into a timer. See the web page for details.

2. Keeping MAKITA 6347D batteries cool makes them last longer.

3. Don't leave them in the tool if they are easily removable.Should a cell ever short out and leak it will damage the tool.

4. It doesn't matter in what state of charge you store the MAKITA 9100 battery, but not having them charged when you want to use them kind of defeats the purpose and utility of the tool. I charge mine and put in shop refrigerator. Keeping them there slows the self discharge way down so they
will hold a charge for several months.

it's important to care your power tools battery as you just bought it. also, choose high quality battery is important, there is battery resource for you: http://www.electronic-parts.com.au/power-tools-batteries.htm

New Technology Lithium Nanowire Boosts Li-Ion Battery Capacity by 1000 Percent

Researchers at the Stanford University Department of Materials Science and Engineering have developed a technique for making lithium ion HP PAVILION DV2000 batteries that hold ten times more charge than current models. This could extend the driving time of electric cars and the life of mobile devices such as cell phones, music players and cameras by the same amount, making a typical laptop Compaq Business Notebook 6910P battery last 40 hours instead of four..

"It's not a small improvement," researcher Yi Cui said. "It's a revolutionary development."

Traditional lithium ion HP KS524AA batteries use graphite as the anode, or the part of the battery that positive current flows into. Scientists have long known that a much higher theoretical charge could be achieved with a silicon anode, but due to a quirk of silicon's nature, until now such anodes have been impossible.

Silicon expands when charged with lithium ions, and then contracts again as the charge flows out. Typically, one such charge-discharge cycle causes the silicon to be pulverized, making it ineffective for future cycles.

Cui and his fellow researchers overcame the problem by growing a cluster of silicon nanowires directly onto the stainless steel that serves as the battery's current collector. While these nanowires, originally on thousandth the thickness of a sheet of paper, swell to about four times their size when charged with lithium, they do not fracture when they shrink back down.

On the first charge cycle, the anode attained silicon's maximum theoretical charge. Subsequent cycles achieved 75 percent of that charge and maintained it even over many charge-discharge cycles.

Cui expressed optimism that the technology could be commercialized within "several years."

"We are working on scaling up and evaluating the cost of our technology," he said.

Cui has filed a patent for the technology and says that he is considering either starting his own company or forming a partnership with an existing battery company to further develop and market it.
