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.

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.

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.

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.
