admin — Sun, 13 Sep 2009 15:40:49 +0000

You have the excellent expensive laptop! It’s great! But at the responsible moment it is out. That’s a real life! Everything’s happened! Laptop can’t work for a long time after one charge of battery not even of modern technologies in area of production of batteries.

Maximally effectively using of an accessible energy is a decision of this problem. What rules you must follow by using the battery to prolong its work. Buying your laptop it is necessary to charge the battery fully and after that you have to discharge it completely. Charging and discharging it 3-4 times you may use it to get the best results.

Use the program for control by an energy-savings which adjoin your laptop. Good choice of a type give you a much prolong of your work. I have tested it using the Sony Laptop Batteries and HP Laptop Batteries. It was very comfortable.

You can disconnect not in use components for the minimizations of electrical energy. It is such components as CD/DVD ROM, Lan card, PCMCIA slot, Bluetooth and Wi-Fi. Don’t use maximal brightness without the necessity because the lamps of illuminating from beneath very utilize valuable energy. Quality of image still available for the reading in such notebooks that use such batteries as HP Laptop Batteries, BenQ Laptop Batteries, Gateway Laptop Batteries and others.

Try discharge the battery completely minimum once a week if you are using your laptop stationary. Or you can work with your notebook at home without the battery

Do not do it!!! Finally, we must know what can not to do with your battery if you want to use it maximally long. Turned out Li-ion battery is very sensible to heating. With confidence it is recommended: Do not admit superheat of trunk. It does not depend on the mark of the notebook’s battery such as Acer Laptop Batteries, Apple Laptop Batteries, Asus Laptop Batteries and others.

It can happen by blocking of the cooling system. For example, do not put your laptop on the blanket or pillow during your work on a bed. Active system of cooling has the ventilator on the bottom of device, which blows out air inward. Blocked opening leads quickly to the superheat of all system.

The permanent finding in the charged device is the next thing what damages the modern battery. To press out maximum from the accumulator of notebook turned out the battery is the most unreliable part of notebooks. In spite of brand it gets broken after 6 or 8 months if you are wrong in use. That is why the manufactures makes warranty on the source of feeding only 6 months as usual.

Tips & Advice For iPhone Battery Care

admin — Wed, 24 Jun 2009 04:10:14 +0000

Retaining the quality of your iPhone battery will save you a fair amount of money in the long run, so I would like to take a moment and offer some tips and advice on iPhone battery care and how you can optimize the life and charge of your battery to enable you to keep that cash in your pocket for as long as possible.

So the first thing to mention for iPhone battery care would be a proper charge cycle, a correctly maintained iPhone battery can retain up to 80% of it´s full capacity for 400 full charge and discharge cycles, therefore it is important to not overcharge, or undercharge the battery whenever possible. Allowing your iPhone´s battery to run completely flat once in a while is great, but at other times allow it to run as low as possible before charging it again, and when you do charge try to achieve the maximum charge replacing full life back into the battery.

Achieve the maximum ability from your battery – this will not only help you monitor the life of the battery, but also take us back to tip one and ensure a good charge cycle is in operation. For example an iPhone 3G genuine battery will offer you 12 hours of talk time, 10 hours of video viewing, 9 hours of Wi-Fi use or 30 hours of audio playback from a full charge, try to be aware of how your iPhone is being used and how the battery is standing up to the task – also bearing I mind that standby time is somewhere around the 300 hour mark.

Allow the battery to breathe – if you are charging your battery in some carrying cases they tend to generate excessive heat which can affect the capacity of your battery, if you are aware that your iPhone is becoming warm during it´s charge remove it from it´s case prior to commencing the charge.

The ideal temperature for your iPhone and it´s battery is between 32 and 95 Fahrenheit. Also when charging from a USB to a computer ensure that the computer is switched on, a sleeping or turned off computer can cause the iPhone battery to drain which will disturb your charging cycle and degrade the battery.

And one last pointer, is try to generate regular use from your phone, the lithium-based batteries perform better when the electrons are kept active inside, and make sure that whatever happens with your charging the iPhone battery receives your full care by giving it a minimum of one full charge (100% of the battery life) per month.

These iPhone battery care tips have been provided by iPhonePartsPro – your one stop shop online for all iPhone spares, and parts for home repair and maintenance, they also stock a great variety of genuine iPhone batteries for all models and should not be underestimated when you are seeking a quality service.

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

admin — Tue, 26 May 2009 11:12:27 +0000

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.

Laptop Battery an Indispensable Component for Your Laptop

admin — Sun, 24 May 2009 16:52:08 +0000

Battery is what works as powerhouse for all electronic gadgets including laptops, camcorders and IPods. These batteries supply electrical energy which makes laptops work for you.

This battery is manufactured keeping in mind the facets of portability just like watch battery and somewhat like car battery so that it can withstand the operating conditions properly.

Sound laptop batteries generally last for more than 5 years and that too depending upon the factors like programs you are running and power needs of your system. But many times it happens that you forget to charge your laptop battery and resultantly, you cannot work upon laptop unless you substitute it with replacement battery.

When you are contemplating to buy laptop battery, you will be normally having perhaps not more than two battery options. But before buying it, you must consider about the technology used and make sure it is absolutely efficient for your laptop.

Kinds of laptop batteries There are different kinds of laptop batteries available that can be used in your computer. Some of these kinds are listed below: The NiCad battery or nickel cadmium battery is generally used in virtually every laptop. This battery can be charged for limited number of times and can work for longer hours in comparison with other batteries like nickel hydride among others.

But you have to be cautious every time as you have to charge it before it goes dead. This is because once it goes dead; you will be crippled as it has no back up option available with this. Nickel hydride battery: this is another battery option available with you. This is an extension of technology in batteries as it can hold more power back up in comparison with the previous alternative. It has better memory effect as you can reoperate it after it becomes used up.

Nickel ion battery: this is far more superior battery and can hold greater power back up than rest of the available options. The best part about these batteries is that it supports multiple kinds of batteries in the laptop system. Ways to improve battery life You can opt for any of these options for your laptop, but it is imperative to learn about techniques using which you can improve the performance as well as life of your battery system. Following are listed some of these top rated techniques: Conditioning: this technique simply means first of all, completely discharging the battery and thereafter, fully charging it.

This practice has to be undertaken around at least twice a week in order to retain full capacity of laptop battery for longer span of time. You should refrain from the habit of storing your laptop battery below 50ºF or above the levels of 95ºF. In other words, you should avoid leaving your laptop battery either in car of storage room where you do not have stable climate control. In order to extend the usability, you must discharge the battery by about 50% capacity in around 3 years.

These top most valuable techniques can certainly help you in getting better accessibility with the same laptop battery for longer time period.

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.
