How To Make Your Laptop Battery Live Longer
Laptop battery like most people–eventually and inevitably, they die. And like people, they don’t obey Moore’s Law–You can’t expect next year’s batteries to last twice as long as this year’s. Battery technology may improve a bit over time (after all, there’s plenty of financial incentive for better batteries), but, while interesting possibilities may pop up, don’t expect major battery breakthroughs in the near future.
Here’s how to keep your laptop battery working for as long as possible.
Don’t Run It Down to Empty
Squeezing every drop of juice out of a lithium ion battery (the type used in today’s laptops) strains and weakens it. Doing this once or twice won’t kill the battery, but the cumulative effect of frequently emptying your battery will shorten its lifespan.
Keep It Cool
Heat breaks down the battery, and reduces its overall life.
When you use your laptop, make sure the vents are unblocked. Never work with the laptop on pillows or cushions. If possible, put it on a raised stand that allows for plenty of airflow.
Give It a Rest
If you’re going to be working exclusively on AC power for a week or more, remove the battery first.
Otherwise, you’ll be wearing out the battery–constantly charging and discharging it–at a time when you don’t need to use it at all. You’re also heating it up (see “Keep It Cool,” above).
With luck and proper care, your battery will still be useful when you’re looking for a new laptop.
Longer Life Between Charges
Myth: Adding RAM saves battery life.
True, more RAM means less hard drive access, and the hard drive uses a lot of electricity. But RAM uses electricity as well, and unless you’re doing a lot of multitasking (not a good idea when you’re on battery power), more RAM won’t reduce hard drive use.
The tips above should lengthen the time before you need to replace your laptop’s battery. But on a daily basis, we’re far more concerned with another type of battery life: how long we can keep our laptop running without AC power. You may know most of the following tips already, but it never hurts to refresh (or recharge) your memory.
Dim your screen: Your laptop’s backlight requires a lot of juice. Keep it as dim as you can comfortably read it.
Shut off unneeded hardware: Turn off your Bluetooth, and if you’re not using the internet, turn off your Wi-Fi receiver, as well. Don’t use an external mouse or other device. And muting the PC’s sound system not only saves power, it avoids annoying everyone else in the café.
Avoid multitasking: Run as few programs as you can get away with. If possible, stick to the one application (word processor, browser, or whatever) you’re currently using, plus your antivirus and firewall in the background.
And if you’re not on the internet, you don’t need those two.
Avoid multimedia: Save chores like photo editing and watching old Daily Show videos for when you have AC power. And if you must listen to music, use your iPod (or similar device).
Know when to sleep and when to hibernate: You need to think about when you want to save power by sending your laptop into Standby or Sleep mode, and when you want to hibernate it.

The Compaq SLT/286 (1988), prices starts at 99. The machine offers a bright high-resolution display that supports the VGA video standard, the first laptop with that feature. It has a 12-megahertz 80C286 processor, a new low-power chip that is among the faster 80286 microprocessors, and it is certainly capable of handling most applications. And it has a detachable keyboard, another first among laptops. It is 8 1/2 inches deep – 2 to 3 inches less than the other leading laptops at the time The SLT/286 provides mass storage in the form of a 20-megabyte or 40-megabyte hard disk drive. The shock-mounted drive is a new design that can withstand up to 80 G’s of impact, or a ride in the trunk of a New York City taxi, whichever comes first. Data is transferred through a high-capacity (1.44 megabyte) 3.5-inch diskette drive. An optional 2400-baud internal modem is 9. At 14 pounds, including the battery and the hard disk, the SLT/286 strains the definition of laptop. Still, it is five pounds lighter than Compaq’s lunchpail-shaped Portable III, a significant difference among portables. Most important, it runs for three hours on one battery charge. An optional backup battery pack (9) weighs two pounds. One drawback of the machine is that it does not support color, but then neither does any other laptop. (High-resolution flat-panel color displays will begin arriving next year.) Another surprise is that Compaq, which has forged its reputation for high-performance machines …

Things You Should Know About Cheap Laptop Batteries
Laptop has become very important in our lives, so that the power source also very important for efficiency and survival of our laptops. If the laptop cannot be used for more than two hours the user will get stuck with a device created for speed and mobility but shut down very quickly because the electricity supply is inefficient.
There are many types of batteries such as nickel hydride, lithium ion batteries and nickel-cadmium batteries. Batteries price depends on the materials used to manufacture them. Among these three batteries, nickel cadmium batteries are the cheapest. The price of nickel cadmium batteries can range from $ 50 to $ 100.
Nickel hydride battery is a little expensive compared to the cadmium batteries. The price of nickel hydride batteries can range from $ 80 to $ 150. A lithium polymer battery is more expensive than the two types of batteries mentioned above.
Another discovery is revolutionizing the laptop battery is a new external battery that offers run-time of about seven hours in about half the price, but also depends on the programs used on a laptop. Many vendors on the internet offer cheap laptop batteries when purchased in large quantities.
Some companies offer a discount on the battery if the same company that produces laptops. Alkaline batteries are the cheapest among batteries, but bear the highest cost per cycle. Other cheap laptop batteries include lithium ion batteries and lithium ion polymer batteries. Cheap laptop batteries are also available in the Chinese market and can be sent to the United States with reservations over the Internet.
Life of a battery can be increased about fifty percent, so lowering the same price. Many preventive measures can be taken in order to increase the battery life like – fully discharging and charging the battery at least once a month back, the battery remains cold and dry, and make sure that the battery is not overcharged.

How to make your laptop battery lasts longer
With the latest portable PCs, working on the move has never been easier, but laptops are still slaves to the National Grid.
You can do practically anything on a modern laptop, but their advanced features drain battery life to the extent that you can only get a couple of hours out of your laptop before it turns up its toes.
While battery life is a chief cause of mobile moans, it’s possible to get significant improvements by simple good practice and a few software tweaks. To help you get the most from your laptop battery, here are seven easy ways to make it last longer.
1. Dim your screen
The screen is one of the most power-hungry parts of the laptop. It takes serious amounts of battery power to keep your display looking clear and bright. Saving this power is simply a question of turning the brightness down. The screen brightness button is usually located as a second function of one of the F keys, and is represented by a little sun symbol with up and down icons. To use it, just hold down the correct function key and then choose up or down.
2. Change power settings
Windows Vista comes with some great power features, which enable you to eke out the best performance when you’re plugged into the mains, and optimise battery life when on the move. Type power options into the Start Search box and choose Power saver from the list. The Windows Mobility Center has more methods for saving battery life. These include settings for powering off the monitor and kicking into sleep mode more quickly.
3. Switch off Wi-Fi
One of the biggest battery sappers is the wireless networking capabilities built into most laptops. Wi-Fi drains the battery by constantly drawing power from the battery and, when not connected, looking for networks. When you’re using your laptop away from the grid, the likelihood is you’re away from wireless networks, so you can turn this device off. Many laptops have a function button that enables you to turn off the wireless adaptor manually to save yourself the unnecessary waste, but older laptops often don’t have this. If this is the case, just go to the Control Panel, access the Network Connections menu and disable your wireless connection manually.
4. Turn off peripherals
Using USB peripherals can put a big drain on your system, because your motherboard has to power them, so unplugging everything saves juice. USB sticks, mice and webcams are common offenders, so copy all your information across and eject your devices as soon as possible, and put up with laptop track pads over your USB mouse. Many laptops have function buttons to turn off the built-in webcam, which drains the battery if given the chance.
5. Eject your disc drives
Having a disc spinning in the drive is a huge drain on resources, and many programs constantly do this. Simply eject your discs before you switch to battery power to gain vital extra minutes from your working day.
6. Invest in some hardware
Good practice can go some way to extending your battery life, but if you need to use your laptop throughout your working day, you’re going to need some help. Most laptops come with a six-cell battery, but many manufacturers offer eight- or even 12-cell optional upgrades, which can double your power. The alternative to expensive laptop batteries are products such as the Philips Portable Power Pack, which gives you valuable extra hours for all your devices. The Philips is a compact battery unit that has adaptors for most laptops and mobile phones, which is portable enough to be placed in a bag and has enough capacity to double the length of your charge.
7. Disable features
Windows Vista has some handy built-in features, but many put demands on your system that are unnecessary when working on the move. Take the simple measure of turning off Windows Aero and the Windows Sidebar when you’re on the move to make your laptop more efficient.

Tips for a Longer Laptop Battery Life
Just as the fuel is the driving force behind automobiles, so is the battery for laptop. Money is not the only prerequisite to owning a laptop. It is extremely important to know the basic steps required to prolong your laptop battery life. Today, mobile computing has become an integral part of our day to day life. Although, there are other external factors responsible for life-span of your battery such as the cell components of your battery, its make and model and genuineness of the product. Purchasing cheap laptop battery can put you in a difficult situation given the fact that most of these cheap laptop batteries available in the market are either Chinese made, refurbished or used batteries and/or made of unknown dangerous chemical compounds. Since laptop users are at a higher risk of procuring sub-standard products therefore one must be well versed with the properties and technicality of laptop batteries.
Listed below are few tips on how to prolong your laptop battery life through correct usage:
A. Put screen in dim mode
Keeping your laptop screen bright can drain away the battery energy. So, the ideal measure to make a difference to your battery life is to reduce the bright of the screen to dim mode. B. External input device
After the use of USB and other external peripherals, the user is recommended properly shut the device before removing from the laptop.
C. Extra RAM
The system uses the virtual memory which in turn uses the hard disk when the RAM memory runs out. And, this is relatively a less efficient option in terms of power consumption. Although, it is also true that additional RAM means more consumption of energy, this measure is best suited to those users who are often in the need of extensive virtual memory.
D. Reduce background application
CPU or the Central Processing Unit is the backbone of the laptop. By avoiding unnecessary load on the CPU, one can drastically reduce battery energy drain. Therefore, it is a good practice to shut down background applications when not in use, such as desktop search applications.
E. Battery cycle
In contrast to the common belief that batteries last longer if plugged or remain charged (when in use) all the time, it can prove harmful lithium based laptop batteries. Electrons in the battery should be allowed free movement occasionally in order to enhance the battery-life. So, the least one can do is discharge your battery once in a month.
Hibernating is a best option over standby mode. It allows the user to retain and resume from where one left without burdening the laptop battery energy. So, this mode is more energy efficient than shutting down your computer and booting all over.
The life of a laptop battery depends largely on the usage of the equipment. In short, mishandling of your laptop will simply break your laptop battery.
