Battery Wiki - Best Laptop for 2011 by bestlaptopbattery.co.uk

Shopping around for laptops is a pain. There are so many sizes, prices, and gadgets to choose from, and unless you are a firm brand believer or a gamer, you are most likely not going to walk into a store with an idea of what you want. When asked, you’ll probably be more concerned with a price tag rather than the display clarity or processing speeds. But all laptop classes aside, the laptops below are the best on the market, and nearly all laptop reviews will agree:

Alienware M11x
Gamers can’t beat the bang for their buck with this Alienware laptop. For only a little over $1,000, users get excellent graphics and battery life, as well as a great 5.1 surround sound Klipsch speaker system. The look of this laptop is still the same as traditional Alienware laptops, but its performance has made leaps and bounds making it the ideal portable gaming laptop.

MacBook Pro
Apple has it right with it’s line of MacBook Pros, and the newest 15 inch edition comes with a majority of updates many had hoped for including extended battery life and second generation Intel processing chips. The MacBook Pro also has AMD graphics and the new Thunderbolt I/O which also makes it an awesome workhorse.

Samsung Series 9
The 13 inch Samsung Series 9 makes the list as it is the only Windows laptop to ever come so closely to trumping the MacBook Air. The 13-inch Samsung Series 9 has a longer battery life, an amazing display, and the second generation Intel Core i5 CPU making it an excellent ultrathin laptop. Unfortunately, it comes with an incredibly high sticker price which may make it off putting to certain buyers.
There are several other laptops that receive honorable mentions including the MacBook Air which was released earlier this summer; however, the three mentioned above take the cake so far. These laptops range in functionality, but they are overall great pieces of technology, and it is hard to find a user that doesn’t love them. While all, with the exception of the Alienware M11x, are a hefty investment, each machine is well worth the price paid.

Tips for cheap to recycle green batteries

Lithium-ion batteries are a major step up from conventional batteries, but there is currently little economic incentive to recycle their lithium — and that’s the necessary final step in a “green” vehicle, according to global business research and consulting firm Frost & Sullivan.
Is your laptop starting to feel more like a desktop, constantly needing to be plugged in and recharged? This is a classic sign of capacity loss, where batteries become increasingly unable to carry a charge. Unfortunately, battery degradation is unavoidable. All batteries have a lifespan, and with a life expectancy of 2-4 years, the Lithium-Ion laptop battery is no exception. Fortunately, there are several steps you can take to slow the degradation process.
Lithium is a soft metal that has several uses, including medicine and nuclear energy.
The amount in an automotive battery depends on the power needed: around two kilograms for a plug-in hybrid, and around 10 kilograms for a pure-electric vehicle battery that produces more kilowatts, according to Aswin Kumar, automotive and transportation industry analyst for Frost & Sullivan. The lithium in a battery(Hp dv9000 Battery, Hp dv9500 Batteries) is completely recyclable, but it’s currently not cost-effective.
“The recycled lithium costs as much as five times the cost of lithium produced from the least-priced brine-based process,” Kumar says.
“It is not competitive for the recycling companies to extract lithium from slag or com
etitive for the (manufacturers) to buy at higher price points from recycling companies.”
Right now, much of the value in recycling such batteries comes from other materials they contain, such as nickel and cobalt, which are priced much higher than lithium — but technology marches on.
“Future battery chemistries under research and development, such as phosphate or manganese-based  chemistries, have little or no valuable metals like cobalt or nickel,” Kumar says.
“Thus, there is a net negative value for recycling, as the effort to recycle only for lithium from these chemistries would be very high.”
Some newer battery technologies will require twice the amount of lithium as current batteries.
There’s enough lithium to meet global demand, but much of the readily-available metal is in countries that aren’t always politically stable, many of them in South America.
If the supply is disrupted, the major threat manufacturers face is the time it takes to get lithium (Hp dv6000 Battery,  hp nc6400 battery) to market from new mining resources, Kumar says.
He also notes that only a few producers control the market, with the top five accounting for 80 per cent of lithium production in 2009.
China, which has one of the world’s largest lithium reserves, is now ramping up production.
And although we have lots of it, Kumar warns that it should not be the sole future source of automotive power, and that research and development on other power sources is needed to avoid lithium dependency.
