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

How to Judge the run time of dell laptop battery

DELL Laptop Battery have two main ratings on them: Volts and Amperes. Because size and weight of laptop battery is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:
14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This dell laptop battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this Laptop Battery could power your laptop for 2.8 hours.
Upgrade your dell laptop battery from Ni-MH to Li-ion
Ni-Cd, Ni-MH and Li-ion dell laptop battery are all fundamentally different from one another and cannot be substituted unless the laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our hp laptop battery. Finder above to find all the compatible laptop battery for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from Ni-MH to Li-ion, you will typically get longer run times.
For example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new Li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the Li-ion battery.
Example.Li-ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt HoursNi-MH: 9.6 Volts x 4 Amperes = 38.4 Watt HoursThe Li-ion is stronger and has longer run time.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

How to check and replace the HP Pavilion NX9100 Keyboard

When there are something wrong with your HP Pavilion NX9100 Keyboard, take a time to read the following. It tells you how to check and replace the HP Pavilion NX9100 Keyboard.
1.To start with, take out each key out from the laptop keyboard. Use a small screwdriver to carefully pry each key by making it loose. As they become loose, keys will simply pop off. Also, take out the rubber piece present under every key. Keep the keys and rubber pieces in different containers.
2.Once you have removed all keys from the HP Pavilion NX9100 Keyboard, you will have to clean the keyboard from the inside. Use cotton swabs or ear bubs and slightly dip them in water. Avoid getting them too moist, as excess water can damage the laptop keyboard. Meticulously clean the whole HP laptop keyboard using moist cotton swabs, laying extra emphasis on key spaces.
3.Now, start cleaning keys you had earlier removed and kept in the container. Use foam rubber and lighter fluid to clean each key alone. This will help in removing any sticky substance present on keys. Apply any household cleaner on these keys and let them stay for about 15 minutes. After this, wash all the keys properly using hot water and let the keys dry completely.
4.The small rubber pieces which you took out earlier and kept in the container have to be thoroughly rinsed in warm water, after you have sprayed a household cleaner on them. Soak these rubber pieces up in paper napkins so that they dry quickly.
5.To lubricate the keys, place all keys (facing top-down) on a flat surface. Apply mild lubricant from all sides, on all keys and leave them to dry. Avoid applying too much lubricant instead go for a light coat. Similar to the manner in which you lubricated the keys, apply mild lubricant on the HP Pavilion NX9100 Keyboard surface and let it dry.
7.Once you have cleaned and lubricated all the parts, carefully reassemble the laptop keyboard. Begin with placing all rubber components on the HP Pavilion NX9100 Keyboard. Next, fix all keys in their respective positions cautiously securing the wire in these keys. Use your finger and press down all HP keyboard keys, one at a time, firmly so that they fit properly in the slots. That is it.
Sometimes you may find certain keys of your HP keyboard not working properly. You type those keys but there is no output on the screen or you need to press these keys firmly to get a result. You face this problem if you accidentally spill any liquid substance on your HP Pavilion NX9100 Keyboard, or due to dust accumulating on the inside of the keys, pressing certain laptop keyboard keys really hard while playing games or even due to absence of lubrication.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

The correct methods of using and maintenance Gateway 1100 AC Adapter operation are: first AC adapter DC output plug into the notebook’s power jack, and then put into the AC input plug on 220V AC power outlet; and should be unloaded first when the AC input plug unplug, And then pull out the DC output plug.
The Voltage must be within 10% of your original Gateway 1100 AC Adapter Voltage. The Amps may be higher but they cannot by lower. If you are purchasing a universal ADP-65HB Adapter or Car Charger you will need to work out the Watts of your original Gateway 1100 AC Adapter and select the universal Gateway 1100 AC Adapter or Car Charger with the same Watts or next highest Wattage.
If the plug (unloaded) when reversing the sequence of the adapter will communicate Department unlade state, are not allowed to communicate Department adapter no-load state, for his work on the pulse, and no-load when the switch transformer windings to generate highly anti-peak voltage breakdown, such as IC, capacitor, such as ac adapter voltage-sensitive components. Although the current AC adapter has been set up its no-load protection circuit, but because of the design is required to look up to other problems, such protection circuit protective effect is very limited. To find out the voltage & current, turn your notebook over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below.
The voltage figure will have a “V” after the number i.e 19V and the current will have a “A” or “mA”. i.e 3.15A. You can also find these shown on your original Gateway Gateway 1100 AC Adapter if you have it. You can work out the Wattage by multiplying the Voltage by the Amps i.e 20V X 3A = 60 Watts. There is no 60 Watt Acer Gateway 1100 AC Adapter so you will need to select the next step up which is the 70 Watt Gateway 1100 AC Adapter. PLEASE NOTE: If the wattage requirement for your notebook is lower than the 60W or 90W output of the adapter, it will not damage your notebook, your notebook will only take the amount of power it requires. I.E.
If your notebook needs 45W, then either the 60W or 90W will work OK. If your notebook needs 80W then you will need the 90W one as the 75W one will not be powerful enough. If in doubt please email us on our contacts page. Once you have selected you Brand and Model from the Search Wizard it will display the compatible Gateway 1100 AC Adapter under the product column.
