Most laptops today are powered by Lithium-ion (Li-ion) batteries. These are a great alternative to the older technologies since they have a much higher power to weight ratio, are not prone to the memory effect phenomenon and are inherently more environmentally friendly. However, much like the older battery chemistries, they do have a limited lifetime. Although the older chemistries rates of failure were proportional to the number of charging cycles, the capacity of today’s Lithium-ion batteries diminish with age.

When you find that your laptop computer does not hold its charge as long as it used to, or when your system’s power management utility software indicates that its charge level is decreasing, you will need to find a replacement laptop battery to maintain your computer’s operating time. Finding the correct battery is generally a matter of searching for a battery that will fit your computer’s make and model number. In addition, the specifications for the battery are usually found imprinted on the charger.

With this information in hand, there are several sources from which you can purchase a new battery. These generally include the computer manufacturer, specialized electronic and computer retailers and a number of Internet sources. You will also find that, in addition to the OEM battery, there may also be a number of generic equivalents available. Buying a replacement laptop battery directly from the manufacturer is the easiest choice, but you will be paying a premium price for this convenience. Secondary sources of OEM batteries will generally charge you as much as the computer manufacturer and in some cases you may even pay more.

This is true of both brick and mortar stores and online sites that sell computer batteries. But if you are a value shopper, you will soon realize that generic batteries will offer you the same level of performance at a substantial cost savings. Additionally, you may be able to increase your laptop’s operating time by upgrading your battery and choosing one with a higher milliamp rating in the generic equivalent. These higher capacity generic batteries typically cost much less than the OEM’s standard capacity battery.

Generic laptop batteries are produced at the same manufacturing plants that originally produced the laptop battery for the computer manufacturer; batteries are simply an out-sourced item for the computer maker. But these batteries may also be made at facilities whose standards are not as high as the primary plant’s and the only way to ensure that you have purchased a quality battery is to check the reputation of the supplier or the seller, make sure that they provide a liberal warrantee and test the battery by charging it in your computer soon after it is received.

The author performed a case study and examined the cost to buy a replacement laptop battery for a Dell Inspiron. He found that he was able to save more than 50% on a laptop battery that provided a higher capacity and offered an extended operating time.

Choosing Batteries That Compliment Technology

admin — Mon, 22 Jun 2009 15:02:19 +0000

Where would we be without batteries? As we rely more and more heavily on technology which is increasingly of a mobile nature, we need more and more batteries. But it’s not just the number of batteries, but the type and quality.

There’s relatively little point spending more and more money on amazing technology that can store more, do more, and do it more quickly, if you then cut corners when it comes to purchasing batteries.

Whether it’s the battery for your laptop, or the batteries used inside your digital camera, it pays to take time to think about what you are buying, and whether it really does represent not only the best value for money long term, but also whether the performance will be affected.

If your laptop is starting to need charging more and more, and is lasting for less and less time, then you may start complaining, and even feeling that it is becoming less convenient. Whilst we may sometimes be able to plug our laptop in, it may not always be possible, and you can guarantee that when you have something really important to write or do, that’s when your laptop will run out of power and shut down.

But have you ever considered simply replacing the battery in your laptop with a new one? Many people don’t, and it is surprising just how many people decide to pay hundreds of pounds for a new laptop when a new battery could imbue it with a whole new lease of life. As we run more and more software programs, and demand more and more processing from our laptops, it is inevitable that they use a greater amount of power, which will drain the battery quicker.

A rechargeable laptop battery doesn’t last forever, and after eighteen months it will start to lose its performance, and charge slower, and discharge quicker. This may be fine if you tend to use your laptop on mains power most of the time, or demand very little of your laptop, but for many people this deterioration in battery performance can prove to be very frustrating indeed.

But simply replacing the battery will give your laptop a new start, and you will be amazed at just how much quicker and more reliable it appears. Similarly when choosing batteries for your digital camera, choosing high performance rechargeable batteries will mean that you will be able to demand more of your technology, and rely on it for longer. When taking precious or important photos, possibly of moments that are quite unique, you don’t want to lose the opportunity to capture the perfect image because your flash isn’t recharging quickly enough, or the batteries die completely.

By paying that little bit more, you’ll find that the mobile technology serves you in exactly the way it was meant to – reliably, and consistently. Think about how much it would cost you to replace non-rechargeable batteries regularly compared to rechargeable ones – not forgetting the impact on the environment too. A good set of rechargeable batteries will easily recoup their cost within a very short space of time.

Top 5 Tips – How to Make Your Laptop Battery Last Longer

admin — Wed, 10 Jun 2009 15:32:43 +0000

Laptops are the pinnacle of mobility computing. When you have power. Battery life in laptops slowly deteriorates over time, because of the way laptop batteries store and use power.

No matter if you buy your laptop online, off-line and no matter what sales person tells you otherwise. Even if you left the battery out of your laptop, you’ll notice a difference in usage times over a period of years, check Battery University for more information on battery storage.

But following a few simple tips can save your battery life. Note: This also works for phone batteries as well. Charge the battery early and often. Lithium-ion (Li-Ion) batteries will lose charge from age, but recharging it early and often makes sure that the charge is kept throughout the cells.

Don’t Frequently Discharge and Recharge the battery. This is called a “Deep Cycle” and should be only be done every 30 – 40 charges to re-calibrate the battery meters in the electronic device. Take out the Battery when using the laptop plugged in for an extended period of time. Batteries are more affected by heat than any other factor.

The heat produced by a laptop is designed to keep it away from the battery, but if you don’t need the battery in, it’s better to take it out and store it somewhere away form the heat produced by the laptop.

Preferably in the fridge or freezer*

*The battery should never be frozen. Although the freezing point of Li-ion batteries is around -40 degrees C, (way below what most conventional freezers), when storing the battery just make sure it’ll never reach those sort of extreme temperatures.

Never deplete the battery to below their minimum voltage (2.4 – 3.0V per cell)

With these few tips, you should be able to keep your laptop, no matter what brand, continually performing well.

Why Laptop Computer Batteries Explode

admin — Sun, 07 Jun 2009 19:23:57 +0000

Laptop computers are everywhere these days. You can’t sit in a coffee shop or travel on a plane without seeing at least a couple people typing away on their laptops.

The overwhelming popularity of laptop computers and the demands of consumers have driven innovation and development in the technology for both laptops and the batteries that power them.

Laptop batteries are smaller, lighter, and last longer than ever before. They are also safer. Older types of nickel-based batteries can explode if overcharged. New lithium-ion batteries do not run this risk.

Laptop ComputerBatteries Recalled If lithium-ion batteries are safer, why have we seen so many batery recalls in the news in the past few years? First of all, it’s likely that manufacturers are simply taking a conservative approach to managing potential safety issues. Even a relatively low failure rate has caused a recall of millions of laptop computer batteries.

To preserve consumer safety and build confidence in their products, manufacturers often choose to recall their batteries rather than leave a questionable product on the market. As consumers, we should be genuinely reassured by this vigilance on the part of manufacturers. It assures us that they are also taking measures to improve manufacturing methods and the overall safety of the batteries to avoid recalls in the future.

The Makeup of Laptop Computer Batteries Ultimately, though, lithium-ion batteries are compact containers for a great deal of energy. As batteries become more powerful to meet consumers’ demands, the extra stored energy can cause them to become potentially more dangerous.

The manufacturing process for lithium-ion batteries is quite delicate. It involves volatile elements and requires precise assembly. If any metal particles – even microscopic – come into contact with other parts of the battery, an internal short circuit in the battery may result. Errant metallic particles are the cause to which one of the largest battery recalls is attributed. Unless contaminated in this way, a lithium-ion battery will simply shut down when a short circuit occurs.

If a battery is contaminated, however, a short circuit or increase in temperature can cause “thermal runaway,” a situation in which an increase in temperature causes a further increase in temperature and ultimately a destructive result. Because lithium-ion batteries are sealed systems and this heat energy must somehow escape, an explosion can result. Exploding laptop computer batteries have caused extensive damage to pieces of equipment and also, most importantly, have caused human injury.

Lithium-ion Batteries Are Safe Incidents of explosion and injury have been, however, very rare. Manufacturers have added important measures to keep lithium-ion batteries operating safely. Most batteries are equipped with dividers to separate individual cells, meaning that if one cell fails due to excessive heat, it will be restrained from spreading the heat and failure to additional cells.

Manufacturers are constantly striving to improve manufacturing processes and add even more safety measures to laptop computer batteries. Lithium-ion batteries are, in the end, the most effective and safe laptop computer batteries on the market today…

Tips for Running Your Laptop Batteries Better

Tips for running your laptop batteries better.

1. carefully read the user manual for laptop batteries;

2. When the first charge, you should continuously charge the battery to 12 hours, and cycle to fully charge, discharge 3 times to complete the new wake-up battery;

3. If the prolonged use of external power supply, it is best to remove the battery.

Many of my friends did not take note of this problem, use an external power supply is not remove the battery will not only affect the battery life of notebook computers also allow heat to become even heavier burden, shortening the life of notebook computers; see the full text please visit Pai licensing battery Network;

4. Periodic charge and discharge. Even without the memory effect of lithium-ion battery There is a certain inertia effect, a long time not to use lithium-ion will lose their activity, the need for re-activation. Therefore, if a long time (three weeks or more) do not use a computer or found the battery charge and discharge time became shorter and should be fully discharged before recharging the battery is generally a month for at least a full charge and discharge;

5. Recharged when to switch off the best notebook computers, the battery can be completely full of electricity, do not unplug the power half-way in the charge. Shutdown charge than to shorten the boot charging more than 30% of the charging time, and can extend the battery life. Best finish in 30 minutes after charging to use;

6. To prevent exposure to prevent damp to prevent the chemical liquid erosion, battery contacts to avoid contact with metal objects, such as short circuit happen. Lithium battery charge and discharge the number of generally not more than 800 times, on one charge, it will shorten the life span of time.

Propose that we make full use of external power supply, if you use half-way many times Plug Power, and notebook computers built-in battery does not pull out, let the battery great, because each access to external power supply is equivalent to a battery charge.

How to Calibrate Laptop Battery

admin — Mon, 25 May 2009 20:03:41 +0000

A few days ago, my laptop battery started to give up on me. The power indicator would flash and create a weird “buzzing” sound while the computer’s plugged into outlet power. Also, it seemed as if the power wasn’t connected at all sometime.

My solution to that? Calibrating the battery. I explored Google and a variety of other sources to calibrate or recondition laptop batteries. To no avail, I stopped my search there and referred to the HP manufacturer’s handbook.

Surprisingly, it offered some really helpful laptop battery calibration and maintenance tips, which I’d like to share with you:

Calibrating a Battery Pack

When to Calibrate

Even if a battery pack is heavily used, it should not be necessary
to calibrate it more than once a month. It is not necessary to
calibrate a new battery pack before first use. However, make sure
that the battery pack is fully charged,
especially if it is the only
power source.

Calibrate the battery pack under the following conditions:

When the battery status display seems inaccurate.
When you observe a significant change in normal battery
run time.
When the battery pack has not been used for one month
or more.

How to Calibrate
To calibrate a battery pack, you must fully charge, fully discharge, and then fully recharge the battery pack.

Charging the Battery Pack
Fully charge the battery pack when the notebook is in use. To
charge the battery pack:

Insert the battery pack into the notebook.
Connect the notebook to external power through an AC adapter. (The battery light turns on)

The battery light turns off when the battery pack is fully charged.

Discharging the Battery Pack

Disabling Hibernation
To fully discharge the battery pack, disable Hibernation temporarily.
To disable Hibernation:

Select the Power Meter icon on the taskbar or access Power Options > Hibernate, and clear the Enable Hibernate support check box.

Discharging the Battery Pack
After the battery light turns off, which indicates that the battery
pack is fully charged, begin discharging the battery pack.

To fully discharge the battery pack:

Select the Power Meter icon on the taskbar, or select Start > Control Panel > Performance and Maintenance > Power Options > Power Schemes.
Write down the 3 settings in the Plugged In column and the settings in the Running on Batteries column, so you can reset them after calibration.
Select the drop-down lists and set all 6 options in both columns to Never.
Select the OK button.
Disconnect the notebook from the external power source, but do not turn off the notebook.
Run the notebook on battery power until the battery pack is fully discharged.

The battery light begins to blink when the battery pack has discharged to a low-battery condition. When the battery pack is fully discharged, the power/Standby light turns off and the notebook shuts down.

Recharging the Battery Pack

Connect the notebook to external power and keep the notebook connected until the battery pack is fully recharged and the battery light turns off. You can use the notebook while the battery pack is recharging, but the battery pack will charge faster if the notebook is turned off.
Select the Power Meter icon on the taskbar or select Start > Control Panel > Performance and Maintenance > Power Options > Power Schemes.
Reenter the 3 settings you wrote down for the 3 options in the Plugged In column and for the 3 options in the Running on Batteries column.
Select the OK button.

Why Doesn’t My Laptop Battery Persist Any Longer

admin — Sun, 24 May 2009 16:13:21 +0000

Laptop batteries are sometimes a problem for most people. There are certain elementary rules for getting more from your laptop battery. Laptop battery do not persist any longer because of many reasons. Some of the reasons are as follows:

Placing the battery pack in the laptop even if you do not use your laptop for a few days or a week can reduce the laptop battery life. Leaving the laptop battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

Plugging your laptop charger directly into a power outlet or surge protector can also be a reason. You may notice that if you use your laptop as a replacement for a desktop, the battery capacity decreases greatly.

Exposing the laptop battery to high heat or extreme cold conditions can reduce the life of your battery. Batteries are sensitive and exposing them to extreme temperatures can cause major damage. Hot batteries discharge very quickly, and cold batteries cannot create as much power. Heat reduces the life span of lithium batteries.

Batteries do not perform better when they are cool. Extreme temperature conditions completely ruin and suck the life out of laptop battery. Improper storage of the laptop battery can also lead to loss of battery life. Lithium batteries must be stored in refrigerator and not in the freezer. You should store the laptop battery at 40% charge level.

When you store the laptop battery at 100% charge level, you may have unnecessary stress and internal corrosion. On the other hand, if the charge is too low, the battery can eventually become unusable as it will self-discharge. If the battery is not going to be used for more than a month, it is recommended to remove it from the laptop and store in a cool, dry, clean place.

Completely discharging your laptop battery may also reduce its life. Fully discharging your lithium battery can be harmful to the battery’s health. This may even make it completely unusable if levels go too low. If you leave the battery completely drained for a few days, even the safety circuit probably won’t save it.

Running multiple programs at the same time can drain your battery. For example browsing the web and leaving your email client running in the background at the same time drains your battery. Leaving your screen brightness high is one of the fastest ways you can kill your battery. Dim your screen to the lowest level so that you can possibly manage.

Instead consider running only program at a time. In other words, if you’re browsing the web don’t leave your email client running in the background, check it when you’re done surfing the web. Neglecting to turn off and disable unnecessary programs that automatically run on startup may also eat your laptop battery resources.

Using standby mode can eat much battery power. But using hibernate mode instead of standby mode not only conserves the battery power, but it also automatically saves and shuts off your laptop. Improper battery maintenance can reduce the battery life rapidly. Proper battery maintenance includes cleaning the laptop battery contacts that connect your cells to the laptop. As battery power is transferred through the contacts, keeping them clean allows for a more efficient transfer of power.

The First Use of Laptop Battery Noted

With lower prices and configure improve, a lot of friends have been acquired for their own Toshiba laptop. Bought a Toshiba laptop, I do not know the first use of what it should be noted.

First of all, I want to say that everyone at the impression that all Toshiba laptop battery has a service life of all, Toshiba notebook battery life, however in accordance with the number of charge-discharge calculation.

But on this issue a lot of people do not understand very clearly, together with the general Toshiba notebook battery charge and discharge is also the number of at least about 500 times that a lot of friends think Toshiba notebook battery life is about two years.

Toshiba notebook battery, even if unused, will self-discharge phenomenon has happened, once the place for too long, Toshiba notebook will appear the case of excessive discharge. Once at this level, a lot of Toshiba laptop battery even electricity are not rechargeable, and Toshiba notebook batteries, several have come to an end the useless.

In other words, even if your Toshiba notebook battery time do not use, nor capable placed, preferably for a time on a charge and discharge in order to maintain Toshiba notebook battery “state.”

But because of Toshiba notebook lithium electricity itself has a certain memory effect (generally that no memory effect Lithium electricity is wrong, lithium electricity actually have memory effect, but only a very small), preferably within the first Toshiba notebook battery power depletion, and then charge, such an effect would be better.

Of course, the best control of the charging time at 12 hours, otherwise, would also lead to excessive charging Toshiba laptop battery life decrease.

Equally unsurprising is how effective these cameras are — provided they are protected from the elements — at shooting digital video footage in cold and damp inhospitable winter weather outdoors. So long as you protect the camera from rain and snowflakes and shield their sensitive omnidirectional microphones from the distorting effects of heavy wind.

Laptop Battery Life

admin — Sat, 23 May 2009 19:39:40 +0000

How portable is your ultra-portable? Laptops today are getting more and more powerful and smaller by the day, but it almost seems that the developers of portable computers have slightly overlooked another important factor in portable computers; its battery life.

The average laptop model today at most can last up to 2.5 hours of normal use on one full charge. You will have to find a power socket nearby if you plan to use it any longer than that.

Today, there are only a handful of laptops out there in the market that can withstand more than 5 hours of regular use on a single charge. The word ‘portability’ with regards to laptops seems to be limited to the fact that you can bring your computer everywhere, but not use it anywhere. Most laptop manufacturers claim that the laptop has 4 – 5 hours of battery life, but that is only true if you leave the laptop idle.

Fortunately, there are certain laptop models that you can get your hands on if you dream of using your laptop on battery for extended periods of time. At the time of writing, one of the most impressive battery spans can be found on the Apple MacBook Pro 2.4 GHz (2008 edition). On regular use, the battery lasted to an astounding 4.5 hours! Other laptop models with good battery life spans include the Acer Aspire 8920G, the Asus Eee series, the Fujitsu LifeBook series and the Toshiba Satellite Series.

If you are looking to get more hours of battery life, consider getting an extended battery pack for your laptops. These extended batteries are basically larger batteries for your laptop that provides an average of extra 2 hours of use on your laptop. If that is still not enough, you can consider getting an external laptop battery. These are basically huge external batteries (sometimes as big as the laptop itself), that when plugged in can provide up to an extra 9 hours of use. The downside of external laptop batteries is that they are quite bulky and heavy (up to 1.5 kg)

Regardless of the model of laptop and the type of batteries that you use, there are several basic tricks that you can use to extend your laptop’s battery life. One of the easiest ways is to make use of the your computer’s power settings. This option can usually be found when you click on the battery icon on your tool bar. When on battery, make sure that the option is set to a ‘power saver’ mode. In this option, there will be a slight compromise in your laptop’s performance for a longer battery life.

Another easy way to extend your battery’s life is to dim the display screen. Lower the brightness of your laptop’s display to the minimum and you will notice a considerable increase in your battery’s life.

Generally it is not good to keep your fully charged battery plugged in when the power point is plugged in. The constant ‘over-charging’ will decrease the performance of the battery over time. Also, try to only charge the battery when it is fully drained.

How to Increase Laptop Battery Life

admin — Fri, 22 May 2009 04:51:01 +0000

If you do not use the laptop battery for a long time, not capable placed, preferably over a period of time on a charge and discharge, the battery in order to maintain the “status.”

However, due to the lithium power can reach a certain memory effect (Li-General said that no power is not the memory effect, Li-electric memory effect is also a matter of fact, it is very small), preferably within the first battery power run out and then charge, so The results will be better.

Of course, the best time to control the charge within 12 hours, or to over-charge will result in the reduction of battery life. Well, after a long period of use, how to determine whether their batteries can normally work? In fact, it is not hard, is said to the general notebook battery will be used as the increase in the number of working hours gradually reduce, if not the time to use the nominal half of the time, or the use of the time when instability in the long-short, at this time You’ll be more alert, because your battery may have reached the end of life, the best preparation ahead of a danger.

In fact, how to make good use of the laptop batteries, how to extend notebook battery life, has been troubled by the majority of laptop users in the heart of a problem, just above the majority of users for a common type, to a specific brand, a type of product , It is best to ask him the same brand of notebook friends, may have more experience.

Here are some tips to extend the life of your laptop battery:

Turn off unused devices

Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason. To save even more power go to the Control Panel, selectSystem –> Hardware –> Device Manager, and disable the following items: Ethernet adapter, infrared transceiver, and Bluetooth radio. You should do this beacause having Bluetooth enabled and not using it actually consumes quite a bit of power.

Decrease hard drive activity

Defragmenting your hard drive regularly will decrease the frecuency with which your hard disk has to spin, therefore the battery will last longer. optimizes the placement of the data on the drive and when a program makes a request for certain data it can be found more quickly. Another way to decrease hard drive activity is to set your paging file to a fix value, and this value should be around 1.5 times the amount the RAM you have installed on your computer.

To set the paging file go to the Control Panel and click through System -> Advanced -> Performance Settings -> Advanced -> Virtual Memory Change. sale-batteries.co.uk
