The 40 Hour Laptop Battery

One of the biggest complaints of laptop users is that their laptop battery doesn’t last long enough. dell laptop battery The necessity to constantly charge a laptop battery can be daunting for traveling business people and college students who need to take notes for hours at a time. What makes these scenarios particularly difficult is that a power outlet isn’t always nearby.

Imagine a world in which you could use your laptop for as long as 40 hours without needing to recharge.Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, Dell TD175 Battery, In a study done by Stanford University researchers a new nanowire was invented that could prolong the amount of time a laptop battery will work without recharging.

Currently lithium ion batteries use graphite anodes to retain their charge. Although this method is reliable, it limits the amount of time you can use your battery. On average, a laptop user could expect to get about 3-4 hours of run-time before needing to recharge.

The nanowires invented at Stanford are made out of a new type of silicon. In previous years, Dell Latitude D620 Battery,other researchers had trouble overcoming the limitations that result from using silicon as an anode in batteries. Over the years, researchers have been looking into silicon due to its ability to hold large amounts of charge. The challenge for researchers was that silicon has a tendency to break down quickly when used in lithium-ion batteries. By inventing a new type of silicon this problem was quickly overcome.

Researchers at Stanford found that their silicon nanowire anode could hold more charge than graphite. Their research shows that this new type of laptop battery could last as long as 40 hours on one charge.

This new technology could revolutionize more than just the laptop battery industry. This could be marketed in many industries that rely on lithium-ion batteries. However, there was no word on how long it would take to charge these new batteries as well as how many charge-discharge cycles they would last.

Further testing is currently under way. Dell 312-0386 Battery,Stanford researchers have filed a patent and expect that this new technology could be in the hand of the consumer in the next few years.

Rules for travelers change often.Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, Dell TD175 Battery, Effective since January 1, 2008 the Transportation Security Administration (TSA) announced that a new rule regarding lithium based batteries would be put into effect. The new rule discusses loose batteries in checked and unchecked luggage.

According to the new flight rule, loose primary lithium or lithium-ion batteries will not be allowed in checked baggage. This rule mainly applies to people who like to pack spare batteries for either long flights or vacations. The types of batteries that this rule applies to are laptop batteries, cell phone batteries, camera and camcorder batteries, etc.

In the TSA’s statement, which can be found on their website, it states that the potential fire hazard from these batteries is considered a security risk. Although lithium batteries are not allowed in checked luggage, they are allowed in unchecked carry-on luggage.

Please note that the new rule does not apply to batteries that are installed in an electronic device. In other words,Dell PC764 Battery, if you take an alarm clock with you or your cell phone, you can keep the battery inside your device. There is additionally a weight rule that applies to loose batteries. Spare laptop or cell phone batteries are limited to 8-25 grams of lithium content.

The following is a summary of some of the most important TSA rules and tips for traveling with lithium batteries:

1. Spare batteries must be kept in your un-checked baggage so that they can be closely monitored.

2. Purchase your spare battery from a reputable company because the likelihood of you getting a defective battery decreases.

3. Make sure your battery has not been recalled. Often companies offer a list of recalled batteries directly on their site. If not, you can check the Consumer Product Safety Commission’s site for information.

4. Package your batteries well.Dell TD175 Battery, They should be separated from each other and insolated so that they don’t touch any metal. Proper packing decreases fire hazards that could result from keeping your batteries near metal such as keys or coins.

5. You can easily damage a battery by applying too much pressure to it.Dell Latitude D620 Battery, Dell 312-0386 Battery, Dell PC764 Battery, Dell TD175 Battery, Make sure your spares are not near any heavy objects that could trigger a short-circuit within your baggage.

6. If any of your spares have an on/off switch, make sure to put them in the “off” position.

The next time you decide to fly, remember these rules otherwise you may have your expensive replacement batteries confiscated.
