How does Li-Ion HP Laptop Battery Work

Now Lithium-ion batteries are play more and more important role in our lives. We use it in laptops, PDAs, cell phones and iPods. They are incredibly popular with us these days. They’re so widely used just because, pound for pound, they’re some of the most energetic rechargeable batteries available. This article will tell you how does Li-ion hp laptop battery work.
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 hp laptop 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 hp laptop batteries are popular because they have a number of important advantages over competing technologies:
1.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.
2.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 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
They hold their charge. A lithium-ion 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 hp laptop battery 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 hp laptop battery, it is ruined.
A lithium-ion hp laptop 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 hp laptop battery pack fails, it will burst into flame.laptop ac adapter, HP AC Adapter, Dell AC Adapter, HP AC Adapter,Toshiba AC Adapter,Acer AC Adapterclick the hot Model below:dell ac adapter inspiron 6000,gateway ac adapter pa-1650-01,Gateway 1100 AC Adapter,HP DL606A AC Adapter,Toshiba PA-1600-06D1 AC Adapter,hp zd7000 ac adapter, Dell d600 ac adapterHP 417220-001 Adapter,Compaq CQ50 Adapter,1501 Adapter,5100 Adapter,Dell Inspiron 8600 Adapter,PA-12 AC Adapter

  1. Below the lid you may discover important things get a minimal considerably less vibrant since the keyboard and surrounding wrist relaxation are colored with various shades of gray. The wrist rest alone is granted a brushed-metal appear that provides a certain high quality touch, despite the fact that I do not assume it really is steel -- Dell wasn't ready to verify possibly way in the time.

    The inside's not as exhilarating, however the keyboard's cozy adequate.
    The keyboard employs rounded, black, isolated keys established right into a black plastic tray. They're quite little but easy to push and I loved a comfy typing practical experience in my quick hands-on -- but I'll observe how it seriously handles within the total evaluate. The trackpad is relatively vast and possesses a slightly tough texture rendering it simple to slide your finger about on. The 2 individual buttons are massive and simple to simply click, which helps make sending your cursor traveling about an online browser as comfortable while it could be without the need of employing a individual mouse.
