Few things are more annoying than the battery low alert popping up on your laptop when you least expect it. Funny how it always happens at the worst possible time - in the middle of finishing an important document for instance or perhaps while booking those airline tickets online for your winter sun. To avoid this annoyance, read on for five ways to extend your laptop's battery life.
Tip 1: Lower the brightness
The most effective way to reduce the rate of your battery's power consumption is to lower the brightness of your laptop's screen. This is usually done via a dedicated button or the Function Key (Fn Key) which doubles up as a brightness button when holding the arrow keys.
Brightness buttons will be marked with a sun icon. To lower your screen's brightness, you'll need to press the button with a down arrow repeatedly, which will usually be next to the sun icon button.
Tip 2: Switch off Wi-Fi and Bluetooth
Another way to save power is to switch the Wi-Fi off when you're not using it, as leaving your connection on can sap Dell Latitude E4300 battery life. As with brightness controls, most laptops have a dedicated switch or a Fn Key that can be used to disable or enable the wi-fi. Check for a button labelled 'wi-fi' or one with an icon that looks either like a radio mast or like the signal bars on a mobile phone. Bluetooth is also worth keeping an eye on, as it's often on even when it's never used.
Tip 3: Move to a better power setting
Your laptop should automatically switch to a more conservative power plan whenever your PC is running on battery power, but it's worth checking this. In both Windows 7 and Vista, click Start, type Power Options and click the Power Options entry that appears. If the High Performance option is selected, change this to Balanced. The Power Saver option will reduce ACER Aspire 6920 battery usage further, but may affect overall performance. In Windows XP, similar options can be found by going to Start > Control Panel > Performance and Maintenance > Power Options.
Select Max Battery for the lowest power usage.
Tip 4: Further Adjust Power Options
In Windows 7 and Vista, click Start, type Power Options and then press Enter. Click the Change plan settings link next to your chosen power scheme, then choose shorter periods of time from the Turn off the display and Put the computer to sleep dropdown menus. Click on Change advanced power settings to fine-tune power settings further still. You could, for example, click the plus sign next to the Hard disk entry, then click the plus sign next to Turn off hard disks and set a lower time to stop your PC's hard drive.
Tip 5: Shut down desktop gadgets
Windows 7 and Vista lets you run useful mini-programs called Gadgets, such as weather tickers, directly from the desktop. Shutting them down can help your laptop battery last longer. In Windows Vista, right-click anywhere in the Sidebar (usually on the right of the screen) and select Close Sidebar. In Windows 7, close individual Gadgets by moving your mouse over a gadget and click the X that appears. To reinstate your Gadgets in Vista, right click the Sidebar icon in the Notification Area and select Open. In Windows 7, right-click the desktop and select Gadgets, then drag and drop them onto your desktop.

I've had this laptop battery for a month now, and it has done its job as it said it would. A fraction of the cost of the official Apple equivilant and thus far a equal counter part. Arrived quickly and efficiently. Im a happy customer and would reccomend to all.
Thought it would be hard to find a ASUS X50N Battery compatable for my old laptop without a lot of running around, but was quick, easy and fast, Good quality product at a reasonable price.
My Compaq Laptop is just over 10 years old, and the last 6 months it was dead. I mean I couldn't turn it on, or charge it. I thought it was the Compaq Presario V5000 Battery, but it was the charger... Any way, my old battery would last like 30 minutes, this lasts around 2 hours, if not more. So well worth the money, considering buying another one for when I'm on the road.
<p>
I am very happy with the Dell Inspiron Mini 10 Battery. It works fine and the price of it was very good (in Greece the price for a similar battery in 3 times more). I am very happy with Amazon and the seller. The product arrived in an excellent condition and on time.
<p>
The HP 485041-001 Battery is pretty good so far. No compatibility problems. Fit and finish is good. The rubber feet needed to be re-glued, I used superglue and no problems so far. Charge time is fast and I got a good 2-3 hours of heavy use out of it which is good because my laptops and power hog. I don't know about long term but if I get 12-18 months out of it I'll be happy and a return customer. Used for 2 weeks so far.

This apple laptop battery works perfectly well, so far we can't tell the difference from the much more expensive apple version. Would recommend as a cost effective alternative
I am really pleased with this Compaq Presario V2617AU Battery although it was three weeks 'til I could use it as my laptop was in for repair.so far so good!! The battery arrived in good time, fitted instantly and seems to have a reasonable operating time. I'm very pleased with it.
There was no problem with the Dell Inspiron 1420 Battery, it arrived on time and worked excelent on my laptop. I recommend the seller and the item. Everything was great.
The HP HSTNN-LB72 Battery arrived promptly and worked great straight out of the box. I would repeat the purchase if I found I needed another battery like this. Pretty good so far. No compatibility problems. Fit and finish is good. The rubber feet needed to be re-glued, I used superglue and no problems so far.

I have used this replacement compaq laptop battery in my laptop and it is working fine. Was reluctant to go for "other brands" replacement battery at a lower price. I was surprised to receive a battery better than the original. With increased rating, this battery should lasts longer.
This Dell Inspiron 1520 Battery was a life saver for me and my Inspiron 1520. Original battery would no longer even charge and just kept giving me warnings on windows login. To those of you that have commented in your reviews that the battery protrudes out the back of the laptop, thats because its supposed to.
ordered this Fujitsu LifeBook AH550 Battery, after finally facing up to the fact mine was dead! arrivved quickly/ good price and works fine, get a good 3-4 hrs out of a charge. good product.
My battery died several months ago (it seemed normal after one year?!) so I bought this battery to give a new life to my computer. there is just a difference with the mAh on my old battery it was only on Wh, was like 26Wh and this one is 48.8Wh but this HP Mini 1000 Battery works perfectly in my netbook and I can now enjoy without having to be plugged so it's just perfect!!
Bought for a colleague who needed a replacement HP Compaq 2210b Battery; was a little unsure as this seemed to be a fairly generic product. I needn't have worried - it was just as described and is working perfectly well. Really pleased; good value and speedy delivery - couldn't ask for more.

Some reviews about G62 Battery:
Does what is says on the can..( as far as I can see....). I have only had the replacement hp laptop battery for a little while , and it works..! Cannot comment on the life of the battery yet...just hope that it is better / longer than the original one fitted with laptop.
Speedy delivery, the HP Compaq 8510w Battery is working perfectly, never had any problems. The web page told me everything i needed to know about the battery and whether it would work for my laptop. Great price and will be buying off you again in the future.
I bought this IBM ThinkPad R51 Battery for an old laptop. It fits perfectly and has enough energy for several hours of normal usage. Since it's larger than the original battery, problem could occur when the laptop should fit into a tight cover...
I got this for my laptop. It works great. The computer software identifies it as a non-official battery but it works fine. The Lenovo IdeaPad Y560 Battery fits perfectly and looks no different to the original. I get about 4-5 hours of use with this battery on average with light use i.e. not playing videos and processor hungry tasks.
A very quick delivery and a great replacement SAMSUNG R65 Battery! It cam with a small guide on how to condition your replacement battery which was very handy. I was a bit worried about purchasing a non official Samsung product but this works brilliantly and I have no complaints whatsoever. Highly recommended!

This is an excellent replacement HP COMPAQ Battery. Picked up immediately by my laptop and has a decent battery life. All in all, does exactly what it says on the tin. As it was quite a bit cheaper than buying an official replacement, I am very happy with my purchase!
I got this IBM ThinkPad T41 Battery for my laptop. It works great. The Thinkpad software identifies it as a non-official battery but it works fine. The Battery fits perfectly and looks no different to the original. I get about 4-5 hours of use with this battery on average with light use i.e. not playing videos and processor hungry tasks.
I am so glad to buy this Lenovo ThinkPad X201 Battery, cause it got so fast that even my computer wasn't fixed to try it. When i tried it it worked perfectly and now i am happy not to be on wireonly again :D P>
Ordered the Samsung AA-PB8NC6B Battery and received it within the timeframe. Does what it says on the tin- been using it for nearly 3 weeks and satisfied overall. Works just fine. The laptop drivers pop up and moan that it is not an original battery but that is all. Apart from that, you would not know that it is not an original part.
My original battery died and I was advised to get a replacement Sony PCGA-BP2NY Battery. I finally found one here and purchased it. The battery is greatand I'm now getting over 3 hours usage from my laptop again, so I'm delighted

Sale Price: CAD $ 51.09
Some reviews about APPLE A1181 Battery and other batteries:
This battery was received quickly and has been discharging and recharging perfectly for the past month. I was worried that it might not fit well in my 3-year-old 13" A1181 white MacBook, but that has been no problem. The original apple laptop battery was still charging at 100% after 3 three years, but it had swelled up and would press on the touchpad mechanism, causing all sorts of problems. I can't predict the future, but after a month, the product deserves 5 stars.
I got this Asus Eee PC 1015 Battery to give me at least 3 hrs of heavy load runtime. Enough to handle major hub to major hub air travel. Chicago/NY/Atlanta to Korea might stretch it(14hrs) tho. Basically the 63WH battery has a higher open circuit voltage than the 56WH battery. Any how, delivery was fast, and actually beat the projected delivery estimate. Outstanding!
Compared to the prices asked by the original manufacturer and/or retail battery shops, this Compaq Presario V2000 Battery offers the best bang for the buck. Actually 1/3 the price offered by HP, this laptop battery gives me nearly 4 hours of continuous usage compared to (MUCH) less than 1 hour with the original battery. I have only been using it for 2 weeks so can't comment on the longevity of the battery but I can say that so far, I am extremely pleased. Highly recommend the seller and their speedy service.
I bought this item a few weeks ago. Standard shipping took only a few days. Battery performs much better than the factory model from Dell. I followed instructions included with the battery in order to "calibrate" it. It just involves charging fully and discharging fully 4 or 5 times. My new Dell Inspiron 6000 Battery now lasts for close to 4 hours with minimal use (internet browsing and word processing). I'm very happy with the product so far.
I've had this Fujitsu LifeBook T5010 Battery for a few months and i feel its worth the money already compared to the name brand ones. I dont know how long the lifespan will be in the end, but for the price i cannot complain. Battery life is what is advertised for the capacity.

Some reviews about HP COMPAQ NX6120 Battery and other laptop batteries:
I have purchased 2 of these NX6120 batteries. They work exactly the same as the original hp compaq laptop batteries with one exception, they don't last as long as the originals. The first battery lasted for approximately one year. That's pretty good considering the very reasonable price.
My satisfaction to this product is far beyond my expectation. It takes reasonable time to complete the first charge. The performance is just like my original IBM ThinkPad R50E Battery - making my battery status light flash in proper sequence and lasting to the time as indicated in my battery meter.
This laptop is going on quite a few years old now. The original SONY PCGA-BP2NX Battery was long dead. I have gone through 2 other aftermarket batteries that failed within a month and required swapping for another. The last one, after swapping for a new one lasted about a year finally to melt after showing poor performance from new. This one however, has worked just as well as the OE one did.
My Toshiba Satellite L500 Battery was nearly dead after three years of use and on top of that it was not connecting at times to my wireless router therefore not getting connected to the internet! I saw this and hoped it would solve my problems, odd but it did. I booted up and bang on the internet with no problems and the battery kept a charge for hours instead of minutes. Odd no clue how the battery could have anything to do with with wifi but hey for now problem solved at a great cost!
I have an Acer aspire 5720 whose original battery sizzled out for some reason and would only hold a charge lasting 5 minutes. After looking at some replacements, I bought this ACER Aspire 5720 Battery for an amazing price but wasn't expecting much. However, it appears to be working even better than when it came in new.

Volt Up helps you save Android phone battery
When there are software programs running in the background and the users are not aware of it, the process sucks away battery life.
Many of us want to extend our Android smartphone's battery life but are not comfortable going into the details. For such users, an app has been launched, named PowerMax which is created by a startup - Volt Up.
441425-001 Battery
"Smartphones that carry the Google Android platform can rest assured their phones will not fail them when they need them most," said Joseph Yossi Weihs, an embedded devices engineer and head of Volt Up.
"Of course we can't make the battery last forever, but in most cases we can double battery life, which can make all the difference, especially during emergencies," Joseph added.
TravelMate 4150 Battery
The technology developed by Volt Up monitors and manages the radios of Android handsets including 2G/3G/4G, WiFi, FM, GPS and Bluetooth. The app puts these radios to sleep according to the needs of the users.
The app analyses the usage patterns of the Android handset, and keeps an eye on the device if the battery is being drained faster. The user is also informed about how much battery power is being saved and used.
PA3395U-1BRS Battery
Google is definitely aware the Android phones are facing some battery problems. When Google co-founder Larry Page was asked about the weak battery life of Android handsets, he said ideally the users should get one day's battery life and if they were not getting it, something was wrong. He suggested it was probably due to third party apps and the way the users used them.
There are brand new A3Fc Battery, Pavilion dv6-1129tx Battery with 1 year warranty at our canada hp laptop batteries & hp laptop ac dapters online shop.
When there are software programs running in the background and the users are not aware of it, the process sucks away battery life.
In simpler terms, the users should simply turn off applications such as the GPS whenever they can. Similarly the background sync, or Twitter app, RSS apps should not be active all the time. The problem is, these are the features which bring people to Android in the first place, so they may not want to disable these apps for more battery life, they would rather charge their battery.

"Of course we can't make the battery last forever, but in most cases we can double battery life, which can make all the difference, especially during emergencies," Joseph added.

The technology developed by Volt Up monitors and manages the radios of Android handsets including 2G/3G/4G, WiFi, FM, GPS and Bluetooth. The app puts these radios to sleep according to the needs of the users.
The app analyses the usage patterns of the Android handset, and keeps an eye on the device if the battery is being drained faster. The user is also informed about how much battery power is being saved and used.

Google is definitely aware the Android phones are facing some battery problems. When Google co-founder Larry Page was asked about the weak battery life of Android handsets, he said ideally the users should get one day's battery life and if they were not getting it, something was wrong. He suggested it was probably due to third party apps and the way the users used them.

When there are software programs running in the background and the users are not aware of it, the process sucks away battery life.
In simpler terms, the users should simply turn off applications such as the GPS whenever they can. Similarly the background sync, or Twitter app, RSS apps should not be active all the time. The problem is, these are the features which bring people to Android in the first place, so they may not want to disable these apps for more battery life, they would rather charge their battery.

1. Ethernet Network Controller
2. WiFi/Wireless
3. Graphic and Display
4. Processor
5. Disks and File System
6. Software
2. WiFi/Wireless
3. Graphic and Display

Ubuntu comes with a power management module that gives us basic control to save our battery life, to open it just go to ‘System’ > ‘Preferences’ > ‘Power Management’.
There are brand new HP Pavilion dv8000 Battery, Dell Inspiron 1420 Battery with high quality at our canada quality laptop battery online shop.
We can extend our battery life by selecting these options from the power management screen:
1. Putting our computer to sleep when it is inactive.
2. Setting our computer to hibernate mode when battery power is low.
3. Slowing down the hard disk spin.
4. Putting display to sleep when it is inactive.
5. Reducing the back light brightness.
6. Dimming display when the computer is idle.
2. Setting our computer to hibernate mode when battery power is low.

Our Wifi/Wireless Radio consumes power when it receives and sends data over the network and we should turn it off when we’re not using it. We can turn off our wifi if our network card supports the enable and disable power control mechanism by using the ‘iwconfig’ command that we can execute in Ubuntu console:
sudo iwconfig wlan0 txpower off
Use the following command to turn our Wifi/Wireless on back again
sudo iwconfig wlan0 txpower on
Note: Replace ‘wlan0′ with your wireless card name displayed in ‘System’ > ‘Administration’ > ‘Network Tools’ under the ‘Network Device’ Drop Down List
Processor

Linux provides a simple tuning mechanism to save energy consumption in our processor by distributing the processing load among the available processors. If you’re laptop comes with multi-processor, we can use take advantage of Linux’s processor balancing feature to save energy consumption by executing this command through the console:

Disk System

Linux maintain a set of files system date meta data including ‘atime’ that shows the last time a file was used. Although this feature is very useful to system administrator, keeping track of ‘atime’ forces our laptop to a write to the disk every time a file is accessed increasing energy consumption from the battery.

Although this feature is very useful to system administrator, keeping track of ‘atime’ forces our laptop to a write to the disk every time a file is accessed increasing energy consumption from the battery.
There are low prices HP Pavilion dv5 Battery, Dell Inspiron 1100 Battery, Dell Inspiron 8600 Battery with low prices.
Setting Relatime
We can disable the ‘atime’ to reduce disk write at the cost of breaking software that relies on ‘atime’. An alternative is to enable the ‘relatime’ option where Linux will update files access times only if they are earlier than the modification time. This change allows utilities to see if the current version of a file has been read, but still cuts down significantly on atime updates. Linux Kernel 2.6.20 and above should support the ‘relatime’ option
Execute the following command in your console to enable the ‘relatime’ option.
mount -o remount,relatime /
Hard Disk Power Saving Options
Some hard disk manufacturer build power saving options into their hardware so that we can reduce the energy that our hard disk consume. We can only turn on this power saving option when we see AdvancedPM=yes after executing the following command in the console:
hdparm -i /dev/sda
This is an example from hdparm:
Model=FUJITSU, FwRev=000000A0, SerialNo=NS9BT742705B
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=DualPortCache, BuffSize=8192kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=234441648
IORDY=yes, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: unknown: ATA/ATAPI-2,3,4,5,6,7* signifies the current active mode
We can enable power saving mode using the hdparm command, for example:
hdparm -B 1 -S 12 /dev/sda
Enable Laptop Mode
We can save our battery energy life by turning on Linux’s laptop mode so that Linux reduce I/O operation when our laptop is under low power. Not every hardware comes with a laptop mode so we need to check whether our hardware supports laptop mode by executing the following command:
sudo gedit /proc/sys/vm/laptop_mode
If you find that the value in the laptop_mode text file is 0 it means that the laptop mode is disabled. Just set it to 5 from gedit and save the file to enable the laptop mode.
Software
Intel introduce PowerTOP, a software that analyzes software’s power consumption.According to Intel PowerTOP work best with Linux kernel with the tickless idle (NO_HZ) feature enabled (version 2.6.21 or later). Currently, only 32-bit kernels have support for tickless idle; 64-bit kernels are expected to gain this feature in version 2.6.23.
You can install PowerTop through the Ubuntu Software Centre and run it by typing the following command from your console.
sudo powertop
“Wakeups per second” is a good indicator for our laptop energy consumption effeciency. Our laptop saves the most energy when the “Wakeups per second” shows a low number. According to Intel the lowest number of wakeups in a Gnome Desktop environment is 3 and we should be able to achieve this by tweaking our laptop hardware configuration or by closing some of the active software in our system.
Below is a sample of PowerTOP analysis on my laptop energy consumption.
According to PowerTOP analysis the main cause of wake up in my laptop is ‘Rescheduling Interrupt’ that is often invoked when my laptop tries to spread the processor activity across my dual Intel Centrino core. Rescheduling Interrupt happens when the kernel IPI “message” is sent to a sleeping core to wake it up from a low power sleep to make it start running a process when the scheduler decides to offload work from one core to another sleeping core.
One solution to minimize the interrupts is to install irqbalance that distributes the interrupts over the processors and cores in your computer system.

Battery powered future coming
Success in battery innovation would be in reducing costs and weight to increase performance, an expert has said.
Android 3.0 Honeycomb coming to Intel's Oak Trail platform
"The next big thing is to successfully reduce the cost in camcorder batteries and a reduction in the amount of time to charge," CSIR manager of the energy and processes and conference chair Dr Mkulu Mathe told News24 at the International Battery Association conference in Cape Town.
Delegates from around the world at the conference discussed ways that batteries can be improved for high-capacity applications such as electric cars. This would have knock-on effects in areas like cellphone and laptop battery packs in terms of charging time, weight and capacity.
"Knowledge is old; thinking is innovative," said Mathe. "There are concerns around cost and the variation of the chemistry. If the weight can go down, it will improve performance, but it's an area that continues to pose challenges."
The biggest modern leap in battery technology came with the introduction of the lithium-ion digital camera battery. Dr Michael Thackeray, John Goodenough, and co-workers identified manganese spinel as a cathode material in 1983.
New technology
"After the introduction of the lithium-ion cell phone battery in 1991, it's been improved by a factor of two. There's been a lot of engineering and now it's starting to plateau," said Dr Steven Visco of PolyPlus Battery Company in California.
"We could think about silicon and package it better," said Professor M Stanley Whittingham of Binghamton University in New York. He first proposed lithium-ion dell laptop batteries in the 1970s.
They warned though, that simply introducing new technology was not a simple matter and there was a time lag before the technology was widely adopted.
"New technology will take 15 to 20 years to come to the market," Visco said.
He also cited the introduction of hybrid vehicles like the Toyota Prius which initially sold poorly before becoming a synonymous with environmental responsibility.
The introduction of zero emission electric vehicles has also had hiccups, as the public charging infrastructure is not yet in place to make these vehicles widely practical.
