|Extend Your Laptop Battery's Life
"Infinite battery life" is the Holy Grail for all laptop owners. In other words having enough power to watch DVD movies and play games, amongst other things without worrying about the laptop's battery life. http://www.askbattery.com/asus-eee-pc-1101ha.html ASUS Eee PC 1101HA battery The ultimate nuclear powered laptop – guaranteed to last a lifetime, sounds far-fetched, but as laptop and battery manufacturers race to develop new technologies in the search to extend contemporary battery life, this may hold true in the future. One recent development employs fuel cells however; the commercial use of fuel cells still lies some way off. http://www.askbattery.com/asus-eee-pc-1101ha-m.html ASUS Eee PC 1101HA-M battery Until a viable alternative is produced we are all stuck with our laptop batteries, yet all is not lost as there are several ways to extend your laptop battery life. Read the tips below to find out how to gain the most from your laptop battery:
Lower the laptop's LCD brightness – a laptop's LCD screen requires a lot of power and the backlight does not need to be at maximum. Lower the brightness to a level which is comfortable to view. http://www.askbattery.com/asus-eee-pc-1101hgo.html ASUS Eee PC 1101HGO battery
Close unnecessary programs – this includes running multiple programs, unused programs and background processes. If these are stopped then some of the memory (RAM) is freed and the processor doesn't have to work as hard. Resulting in lower battery drain. Use Windows Task Manager to view the list of running processes and CPU performance. http://www.askbattery.com/asus-eee-pc-1101ha-mu1x.html ASUS Eee PC 1101HA-MU1X battery
Remove all unused devices and peripherals – modems, wireless LAN devices, USB devices and external drives. Turn off built-in Wi-Fi if you are not using it. All these devices put an unnecessary burden on the laptop battery. This is also true for CD and DVD drives. These devices can also be disabled under Device Manager and saves Windows unnecessary work. Save time by creating a Windows hardware profile, especially if you will be disabling devices regularly. http://www.askbattery.com/asus--eee-pc-1101ha-mu1x-bk.html ASUS Eee PC 1101HA-MU1X-BK battery
Add more memory (RAM) – this is not a myth adding more memory helps battery life. Increased memory means that Windows is less reliant on the virtual memory swap file on the hard disk. Memory requires less battery power than hard disk drives, which requires disks to be spun at high speed. http://www.askbattery.com/asus--eee-pc-1101ha-mu1x-wt.html ASUS Eee PC 1101HA-MU1X-WT battery
Use faster hard disk drives – hard disk drives come in a variety of speeds i.e. 4200rpm, 5400rpm. Higher speed means faster 'seek times' therefore the disk needs to spin for a shorter time drawing less power. Defragmenting your hard disk can also improve 'seek times' helping to save valuable battery power.
While on the road use an AC or Car adapter whenever possible. http://www.askbattery.com/asus-eee-pc-1005h.html ASUS Eee PC 1005H battery
Utilise power management settings – these may be present on the laptop, proprietary or Windows. Set these to maximum or aggressive level to obtain greater battery life. Also check that power management is enabled on the Bios. For certain laptops, if this is not enabled then any power management using a battery monitoring software or Windows will have no effect. http://www.askbattery.com/asus-eee-pc-1005ha.html ASUS Eee PC 1005HA battery s
Carry a second laptop battery – some laptops have higher capacity batteries that fit into the same compartment giving a longer running time. 2-Power branded laptop batteries are rated to have a higher capacity. Some laptops can accept a second battery on one of the empty bays, further boosting the available battery power.
Check the CMOS battery inside the laptop – a dead CMOS battery can draw power from the main laptop battery. This is especially true in older laptops or if you keep setting the date and time regularly.
Disable any auto notification in Windows – this saves valuable resources
Use smaller, simpler programs whenever possible – i.e. WordPad instead of Word http://www.askbattery.com/asus-eee-pc-1005hab.html ASUS Eee PC 1005HAB battery
Clean the battery contacts – clean contacts ensure a good connection, allowing you to get the most out of the battery. Clean regularly using rubbing alcohol.
Use the laptop on a flat surface and ensure the vents are not blocked by clothing or other obstructions – use an air duster or a vacuum to clear any vents clogged with dust. This prevents the laptop from overheating and the internal cooling fan from working overtime and drawing more power from the battery. http://www.askbattery.com/asus-eee-pc-1005had.html ASUS Eee PC 1005HAD battery
Avoid using the laptop in extreme temperatures – high temperature causes the battery to discharge rapidly and at low temperatures the battery will be struggling to power the laptop sufficiently.
Completely discharge the battery and recharge it again – this helps older batteries especially the older chemistries like NiCd and NiMH. Lithium-Ion batteries do not require this unless they have been well used. http://www.askbattery.com/asus-eee-pc-1005hag.html ASUS Eee PC 1005HAG battery Sometimes the smart electronics within the battery need recalibrating and a complete discharge/charge helps solve the problem.
Use the Hibernate or suspend modes rather than shutting the system off and restarting.
Finally possibly the hardest thing to do is minimize playing movies and games, both use the DVD and CD drives. http://www.askbattery.com/asus-eee-pc-1005he.html ASUS Eee PC 1005HE battery
Using an AC adapter or a Car adapter whilst on the move is perfectly acceptable, but is it necessary to carry a separate case with all your laptop accessories? Quite simply no. It can be used on different models and brands of laptops and there are a number of different tips which enable this. This means game playing, DVD viewing and listening to CDs on that long boring plane journey no longer needs to be missed. http://www.askbattery.com/asus-eee-pc-1005hr.html ASUS Eee PC 1005HR battery Plug into the nearest power source available (usually an in-seat socket) and watch those hours fly away.
A Universal Laptop Battery is another unique product. The two different types, which differ slightly in the chemistry of the battery, are Lithium Polymer and the standard Lithium-Ion (Li-Ion). Lithium Ploymer batteries are much lighter in weight and due to their high power to weight ratio, produce enough electricity to power a laptop. http://www.askbattery.com/asus-eee-pc-1005p.html ASUS Eee PC 1005P battery In comparison the larger and heavier standard Li-Ion battery, produces more power due to its physical size. Mobility is not an issue as both batteries are low profile, un-obtrusive and easily fit into laptop carry cases. As with the Universal Car Air Adapter these batteries work with a variety of laptop models. Finally, bear in mind that universal laptop batteries are designed to be used alongside the standard laptop battery, rather than act as replacements. http://www.askbattery.com/asus-eee-pc-1005pd.html ASUS Eee PC 1005PD battery
Laptop Battery Buying Guide
A laptop battery provides a source of electrical energy that supplies needed power to your laptop. The laptop battery uses a combination of cells that are electrochemically active, which is to say, they naturally transmit electrons from one end of the laptop battery to the other, when those two ends are connected in a circuit. http://www.askbattery.com/asus-eee-pc-1005pe.html ASUS Eee PC 1005PE battery A laptop computer battery can be engineered to be highly portable, like a watch battery, or it can be built to withstand extremes in operating conditions, like a car battery.
Just like your car, your laptop computer battery lasts longer depending on how you "drive" your laptop. http://www.askbattery.com/asus-eee-pc-1005peb.html ASUS Eee PC 1005PEB battery Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won't charge fully or stops holding its charge for as long; when this happens, you'll probably want to buy a replacement battery. http://www.askbattery.com/asus-eee-pc-1005ped.html ASUS Eee PC 1005PED battery
When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology. http://www.askbattery.com/asus-eee-pc-1005pem.html ASUS Eee PC 1005PEM battery
Types of Laptop Battery
•The nickel cadmium battery, known as NiCad (pronounced "Nigh-Kad"), used to be the most common type of laptop battery. Nickel cadmium batteries couldn't hold very much power by today's standards, and could only be charged a limited number of times. http://www.askbattery.com/asus-eee-pc-1005peg.html ASUS Eee PC 1005PEG battery NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the "memory effect," meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it. http://www.askbattery.com/asus-eee-pc-1005pg.html ASUS Eee PC 1005PG battery
•The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect, although it wasn't as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. http://www.askbattery.com/asus-eee-pc-1005pgo.html ASUS Eee PC 1005PGO battery The Li-Ion laptop battery doesn't have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.
How Increase the performance of Battery? http://www.askbattery.com/asus-eee-pc-1005pq.html ASUS Eee PC 1005PQ battery
Regardless of which type you have, it's important to properly care for your laptop battery, in order to get as much life out of it as possible.
•"Conditioning," which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery. http://www.askbattery.com/asus-eee-pc-1005pqd.html ASUS Eee PC 1005PQD battery
•Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it's a good idea to condition all laptop batteries regularly, rather than simply leaving them plugged into the wall at all times.
•Your laptop battery should never be stored in an area that drops below 50ÂºF (10ÂºC) or rises above 95ÂºF (35ÂºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled. http://www.askbattery.com/samsung-n310.html Samsung N310 battery
•Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all. http://www.askbattery.com/samsung-n310-13gb.html Samsung N310-13GB battery
All About Laptop Batteries
With the increased usage of laptop computers nowadays, the demand for laptop batteries have reached its peak. Laptop batteries are specific to the make and model of the laptop. There are lots of laptop battery manufactures like septechnologies who are capable of supplying batteries that are compatible with most of the laptops that are available in the market today. http://www.askbattery.com/samsung-n310-13gbk.html Samsung N310-13GBK battery Though there are a lot of manufactures of laptop batteries, there are a few things that have to be taken into consideration while choosing a laptop battery.
ALL BATTERIES ARE NOT THE SAME
http://www.askbattery.com/samsung-n310-13go.html Samsung N310-13GO battery Most of the laptop users still believe that all the laptop batteries are the same. Though the laptop batteries work on the common principle that 'electrochemical reaction created forces a stream of electrons that traverse from one position to another in the laptop batteries and the negative and positive terminals send and receive electrons', there are also many differences between the laptop batteries that are available in the market today. http://www.askbattery.com/samsung-n310-ka03.html Samsung N310-KA03 battery To start with, the location and shape of different terminals of the battery may vary across different models. Moreover, there are three different types of laptop batteries that are available in the market today:
NICKEL CADMIUM BATTERIES
The Nickel Cadmium batteries were the ones used in laptops in earlier days. http://www.askbattery.com/samsung-n310-ka04.html Samsung N310-KA04 battery These batteries were preferred in earlier days as they delivered high output at low cost. However, these NiCd batteries have many drawbacks like overcharging, cell reversing, memory & lazy battery effects and dentritic shorting. Moreover, these NiCd laptop batteries are not environment friendly. Cadmium which is a very heavy toxic metal requires special care during disposal. With these difficulties taken into account, these batteries are not widely used today. http://www.askbattery.com/samsung-n310-ka05.html Samsung N310-KA05 battery
NICKEL METAL HYDRIDE BATTERIES
Nickel Metal hydride batteries are better replacements for NiCd batteries. These NiMH batteries are compatible with most of the older laptops. The elimination of the toxic cadmium in this type of battery makes it environmentally safe than the NiCd batteries. Also these batteries are easily available in the market for a cheaper price. http://www.askbattery.com/samsung-n310-ka06.html Samsung N310-KA06 battery
LITHIUM ION BATTERIES
The lithium ion rechargeable batteries are the type of batteries in which the lithium ion moves between the anode and the cathode. Lithium ion batteries are the most commonly used ones in consumer electronics. http://www.askbattery.com/samsung-n310-ka07.html Samsung N310-KA07 battery They are currently the most popular batteries that are used in most of the portable devices. These LiON batteries have excellent energy to weight ratio, no memory effect, and slow loss of charge when not in use. However, the unique drawback of the Li-ion battery is that its life span is dependent upon aging from time of manufacturing (shelf life) regardless of whether it was charged, and not just on the number of charge/discharge cycles. http://www.askbattery.com/samsung-np-n310-series.html Samsung NP-N310 battery So an older battery will not last as long as a new battery due solely to its age, unlike other batteries. Though the LiON batteries have this disadvantage, the advantages overweigh them is hence it is most preferred laptop battery in use today.
If you are still not sure about what type of laptop batteries to choose, nothing to worry about. http://www.askbattery.com/samsung-np-n310.html Samsung NP-N310 battery You can get the best batteries from experts like septechnologies. With all these kinds of laptop batteries, the industry is still hoping to find an alternative to maximize efficiency and to minimize cost.
How Does a Laptop Battery Work?
There is little difference in how a laptop battery works and how other device batteries work. http://www.askbattery.com/samsung-np-n310-ka01nl.html Samsung NP-N310-KA01NL battery The batteries that power your portable CD players, radios, camcorders etc. are more or less the same except that a laptop battery is more intelligent if you can call it that. Just like the rest of the batteries, laptop batteries too come in different shapes and sizes with the addition to a complex electronic circuit that works in conjunction with the laptop hardware. http://www.askbattery.com/samsung-np-n310-ka01uk.html Samsung NP-N310-KA01UK battery This electronic circuit manages the power that flows into the battery while recharging and the power that flows out of each cell of the battery while discharging, a feature that is not included in ordinary rechargeable batteries for other household devices.
Just like any other battery there are cells inside a laptop battery. http://www.askbattery.com/samsung-np-n310-ka03.html Samsung NP-N310-KA03 battery Each cell is typically 1.5 volts and a number of cells are arranged in series and connected in parallel to deliver optimum power to the laptop or device. A number of cells are connected together to forma a battery. Connecting a number of cells in parallel means to connect all the negative terminals to each other and positive terminals likewise this increases the power delivering capacity of the battery but not the voltage. http://www.askbattery.com/samsung-np-n310-ka03pl.html Samsung NP-N310-KA03PL battery Then a number of these batteries are connected in series (negative to positive terminals to raise the voltage). This is done to optimize the voltage level of the battery. These cells are controlled by an internal electronic circuit in the battery.
The internal electronic regulator is the unique property of a laptop battery. http://www.askbattery.com/samsung-np-n310-ka03uk.html Samsung NP-N310-KA03UK battery This circuit regulates the flow of charge into and out of each internal cell in the battery thus ensuring that each cell has an equal charge at all time in turn ensuring the optimum use and long life of each cell. It also ensures that the cells do not over charge. http://www.askbattery.com/samsung-np-n310-ka04.html Samsung NP-N310-KA04 battery
The plates of each cell react with the electrolyte (chemical/acid) in the battery causing a flow of electrons from the negative to positive terminals and a flow of ions from the positive to the negative terminal this is the flow of current as we know it. This flow continues until the electrolyte loses its acidity. http://www.askbattery.com/samsung-np-n310-ka04es.html Samsung NP-N310-KA04ES battery When the battery is charged the ions are restored to their place in the cell and the electrolyte regains its acidity ready to generate electricity in the cell once again. This process is always the same irrespective of the type of battery.
The process of charging or discharging of the battery is controlled by hardware built into your laptop. http://www.askbattery.com/fujitsu-siemens-amilo-li-3710.html Fujitsu Siemens Amilo Li 3710 battery This hardware ensures the proper functioning of the cells in the battery and warns you of the tile left before you need to recharge the battery. This indicator is displayed in the right bottom corner of the screen in most notebooks or laptops.
Though the laptop battery is rechargeable, like everything it does have a life span and cannot go on serving you for eternity. http://www.askbattery.com/fujitsu-siemens-amilo-li-3910.html Fujitsu Siemens Amilo Li 3910 battery Proper care will ensure that the battery lasts longer than it would without the proper care. A battery will normally last between 500-700 charge cycles before it will need to be replaced with a new one. The number of charge cycles of the battery will depend on the usage of the laptop. http://www.askbattery.com/fujitsu-siemens-amilo-pi-3560.html Fujitsu Siemens Amilo Pi 3560 battery The more often you need to charge your laptop the sooner you will have to replace the battery.
Every laptop model is designed to suit a particular function and so is the battery designed to match the power requirements of the laptop. The design of the battery depends on the weight and size of the laptop. http://www.askbattery.com/amilo-li-1818.html Amilo Li 1818 battery A small light-weight laptop will have its design defeated if the battery weighs more than the laptop itself, so the battery has to be designed to suit the model of the laptop.

How to extend your Dell INSPIRON 6000 laptop battery life? http://www.askbattery.com/amilo-pi-1505.html Amilo Pi 1505 battery
Dell INSPIRON 6000 laptop batteries seem to be fond easily these days. We can find them in our laptops. We all want to make our batteries last as long as possible, and how can we extend our laptop batteries.I find some useful advices from articles.
The first: Battery Memory – When I first got my laptop, my friend recommended to fully drain the battery before recharging it. http://www.askbattery.com/amilo-pi-2512.html Amilo Pi 2512 battery His reasoning was connected to the idea of battery memory. allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half. http://www.askbattery.com/amilo-pi-2515.html Amilo Pi 2515 battery The good news is today\'s laptop batteries have a safety circuit in place to insure the battery doesn\'t reach the point of no return. The safety circuit isn\'t fool proof of course, if you leave your battery completely drained for a few days, even the circuit\'s protective measures won\'t save it.
The second: Battery Calibrating – There is some benefits to fully discharging your Dell INSPIRON 6000 laptop battery periodically, this can be especially important. http://www.askbattery.com/amilo-pi-2530.html Amilo Pi 2530 battery If you start to notice your battery meter is becoming more and more inaccurate, it may be time for some battery calibration. By allowing your Dell INSPIRON 6000 to fully drain, this will help the Dell INSPIRON 6000 laptop battery recalibrate allowing for more accurate measurements of battery life. This should be done once every 30 charges or when you notice battery readings are off. http://www.askbattery.com/amilo-pi-2540.html Amilo Pi 2540 battery
The third: Consequences of Heat – another enemy of Dell INSPIRON 6000 laptop battery life is heat. If you were to leave your laptop plugged in and running for a year, you should expect the Dell INSPIRON 6000 laptop battery capacity to be anywhere between 60% to 80% of it\'s original max capacity. http://www.askbattery.com/amilo-pi-2550.html Amilo Pi 2550 battery This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source. Now you may want to check with your manufacturer ahead of time to check for safety concerns, some manufacturers have mentioned problems such as moisture and dust collecting in the battery casing. http://www.askbattery.com/fujitsu-siemens-amilo-li-1818.html Fujitsu Siemens Amilo Li 1818 battery
The fouth: Battery Storage – If you plan on not using the Dell INSPIRON 6000 laptop battery for prolonged periods of time, then you\'ll want to have the charge level at 40% and place the battery in the fridge (not freezer). Storing the Dell INSPIRON 6000 laptop battery at 100% charge level applies unnecessary stress and can cause internal corrosion. http://www.askbattery.com/fujitsu-siemens-amilo-li-1820.html Fujitsu Siemens Amilo Li 1820 battery On the other hand, if the charge is too low, the Dell INSPIRON 6000 laptop battery can become permanently unusable, due to battery self discharge. This is why manufacturers recommend storing your battery at 40% charge, rather than either extreme .
always keep a spare battery so that you\'ll never miss a Important fair. http://www.askbattery.com/fujitsu-siemens-amilo-pa-1510.html Fujitsu Siemens Amilo Pa 1510 battery Here you will find some of the best prices on replacement Dell INSPIRON 6000 SERIES Battery ,Dell INSPIRON 6000laptop battery adater(chargers), Dell INSPIRON 6000 laptop battery reviews, features, specifications and related accessories.
