Laptop battery usage tips

1. A new battery usually comes in a discharged condition and with a very low capacity. It is generally recommended to fully charge new battery packs before use. Refer to the users?guide of your electronic device for charging instructions.

2. A new battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.

3. Rechargeable battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.

4. To maintain the optimum performance of a battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.

5. It is normal if a new battery gets warm when being charged or used. However, close attention should be paid if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. So, it is necessary to have it checked by a qualified technician.

6. New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be charged. If this happens, it is then suggested to remove the battery from the device and reinsert it.

To better use your battery, please take care of the precautions listed below:
1. Do not modify or disassemble.
2. Do not incinerate or expose battery to excessive heat, which may result in an exposure.
3. Do not expose battery to water or other moist matters.
4. Do not pierce, hit, step on, crush or abuse the battery.
5. Do not place battery in device for a long period of time if device is not being used.
6. Do not short circuit the terminals or store your battery pack with metal objects such as necklaces or hairpins.

Tips for extending your laptops battery life

Everyone wants longer battery life, within reason there are some tricks to help get the most out of your laptops battery.

One fact we all have to accept is that laptop battery life degrades over time. While modern Lithium Ion batteries found in laptops today are much more resistant to degradation they do still lose performance after a couple of years.

After 3 years of reasonable use you will be entering the stage of possible total battery failure.

Most laptop batteries will last a little over 2 hours when new. This usually ties in perfectly with a DVD movie. However often the inability to play DVD movie all the way through is the first indication of reduced battery performance. The problem with DVDs is that they involve accessing the DVD rom drive and are quite processor intensive, this means the laptop cannot enter a reduced power state.

If you want to get a bit more juice out of a battery, fully discharged and recharged it several times in a row. It may be a pain, let your laptop run until the system shuts down. Then recharge it and, if you have time, discharge and recharge it a second time

When watching a movie turn down your LCD screens brightness, this will have quite a big impact on energy usage.

If you know how decrypt the DVD movie and store it on your hard disk drive. This way you won not have to access the DVD ROM drive further reducing the laptop energy usage.

If your lucky enough to have a battery that supports wireless networking then try removing the PCMCIA card or disabling it in the device manager. Wireless networking cards can use quite a bit of energy broadcasting their radio signal.

The Energy Saver control panel on your Mac and the Power control panel in Windows XP allow you to configure your system to power down the screen and hard drive after a period of inactivity.

The last option would be to buy a second battery to change or a large 3rd party laptop battery to massively increase battery life.

Choosing the right battery for portable computing

Laptops are known to be tough hosts on their batteries. The host demands a stream of uninterrupted power but offers a poor working environment in return. As a result, the battery cannot provide the promised runtime and the service cuts short, often with little notice. In this paper we address the unhappy marriage between the host and battery, and examine what causes a battery to deteriorate faster than in other portable devices.

Activate new battery

The new notebook computer should get small electricity for the first time. To activate the new battery, should not use the outer power first, but use up the energy of the battery until the notebook shut down. Then charge the battery with the outer power until the indicator light go out. Then use up the energy again. Repeating 3 times to activate the battery.

What is the best battery for laptops?

Batteries for laptops have a unique challenge they must be small and lightweight. In fact, the laptop battery should be invisible to the user and deliver enough power to endure a five-hour flight from Toronto to Vancouver.In reality, a typical laptop battery provides only about 90 minutes of service. Many users complain of much shorter runtimes.

Computer manufacturers are hesitant to add a larger battery because of increased size and weight. A recent survey indicated that, given the option of larger size and more weight for longer runtimes, most users would settle for what is being offered today. For better or worse, we have learned to accept the short runtime of a laptop.

The energy density of modern batteries improves by about 10% per year.However, the benefit of better battery performance is eaten up by higher power requirements of laptops. This results in the same runtime but more powerful laptops.

How to charge notebook battery?

We should start from the material of the battery. The battery of the notebook computer can mainly divided into three kinds at present. That is 1.Nickel chromium battery, 2. Nickel hydrogen battery, 3. Lithium battery; They are generally expressed as: Nickel cadmium NICD, nickel hydrogen NIMH, lithium Li.

During the last few years, batteries have improved in terms of energy density.But any benefit in better battery performance is being eaten up by the higher power requirements of the laptops. This trend is continuing and the net effect will be the same runtimes but more powerful laptops.

Most laptops are powered by lithium-ion. This chemistry has a high energy density and is lightweight. There is no immediate breakthrough on the horizon of a miracle battery that would provide more power than the current electro chemical battery.

Fuel cells, when available, will offer a continued stream of power by allowing the exchange of fuel cartridges when empty. Unfortunately, commercial fuel cells for laptops and other portable devices are still several years away.Power handling, size and cost remain the biggest hurdles. The early fuel cells will function more like a portable charger than a battery replacement. The fuel cells currently in use have the difficulty in providing spontaneous high power on demand.

The runtime of a laptop battery is based on the activity of the computer. The basic housekeeping, which the computer needs to stay alive, draws less power than, for example, reading, writing, computations and searching for files.Manufacturers prefer using idle time when specifying runtime.

Charge the battery after it is used up and avoid charging it too long.

No matter what kind of battery it is, lithium or hydrogen battery should be charged after it is used up (electric consumption is lower than 1%). This is the best way to avoid the memory effect. The lithium battery also have the memory effect, the difference is that the memory effect is a little smaller than nickel hydrogen battery. Not fully charge and dies charge the battery will cause the chemical property inconsistent, therefore will degrade the battery performance. Propose to deeply discharge the battery once several months in order to optimize the battery. The concrete method is forbid the functions of management of power of operating system and BIOS, supply power with the battery, keep using until the system shuts down. Then charge the battery until it is fully charged. Then resume power management of BIOS and operating system to set up.

A battery in a laptop ages more quickly than in other applications because of heat. During use, the inside temperature of a laptop rises to 45^oC (113^oF).The combination of high temperature and full state-of-charge promotes cell oxidation, a condition that cannot be reversedonce present. The batterys life expectancy when operating at high temperature is half compared to running at a more moderate 20^oC (68^oF) or lower. Leaving the laptop in a parked car under the hot sun will also aggravate the situation. All batteries suffer permanent capacity loss as part of elevated temperatures but lithium-ion is affected more than other batteries.

Some Japanese computer manufacturers have introduced a number of sub-notebooks in which the battery is mounted externally, forming part of the housing. This design improves battery life because the battery is kept at room temperature.Some models carry several size batteries to accommodate different user demands.

Lithium-ion is well suited for laptop users who continually switch from fixed power to battery use. This user pattern is typical for those in the sales,service and medical field. Here is the reason why:

With nickel-based batteries, the charger applies a full charge each time the portable device is connected to fixed power. The battery is put on charge until a signal is received indicating that the battery is full. This signal is in form of a voltage change or rising temperature. Because of the sluggish response, permanent capacity loss occurs caused by overcharge and elevated temperature. Lithium-ion only receives charge if the voltage is low.

Try to reduce the times of using the battery.

The charge and discharge times of the battery are influencing the life span of the battery directly. To charge once the battery advance a step to the ex-service battery. The damage to the battery is more great if often insert and pull out of the power several times during one day, even the battery for is inserted in the notebook. As every time the outer power is inserted just like to charge the battery, naturally that will short its life span. The theory is that but take away the battery is very inconvenience each time. In addition that without the battery, the data will be lost if suddenly power off. So we advise the users not take away the battery to use the notebook. But if the customer wants to save the battery very much, or most of time use the power, and can avoid the danger that cut out, take the battery off when can choose to use the outer power.

How to calibrate the battery

Most laptop batteries are smart; meaning that they know how much energy is left. Such a feature has definite benefits but the readings are often inaccurate. A laptop may indicate 30 minutes of remaining runtime when suddenly the screen goes dark. Here is the reason why:

With use and time, a tracking error occurs between the chemical battery and the digital sensing circuit. The most ideal use of the smart battery, as far as fuel-gauge accuracy is concerned, is a full charge followed by a full discharge at a constant current. In such a case, the tracking error would be less than 1% per cycle. In real life, however, a battery may be discharged for only a few minutes and the load may vary widely. Long storage also contributes to errors because the circuit cannot accurately compensate for self discharge.Eventually, the true capacity of the battery no longer synchronizes with the fuel gauge and a deliberate full charge and discharge is needed to re-learn or calibrate the battery.

What happens if no battery calibration is done? Can such a battery be used in confidence? Most smart battery chargers obey the dictates of the chemical cells rather than the electronic circuit. In this case, the battery will fully charge regardless of the fuel gauge setting and function normally, but the digital readout will become increasingly more inaccurate. If not corrected,the fuel gauge simply becomes a nuisance.

At what point of a discharge does the reset occur? Lithium-ion is considered fully discharged between 2.5 and 3.0 volts per cell. The electronic circuit in the battery is designed to reset between these voltage levels. A problem occurs if the laptop cuts off before this low voltage can be reached. In such a case, an external charger with discharge function may be used. Cadex Electronics manufactures smart chargers and battery analyzers, both of which can be used to test and calibrate the smart battery.

All of the battery has a natural course of discharging, after preserving for a long time; it has already finished discharging naturally. This does not influence the capacity of the battery. While charging for the first time, you should charge the battery to 12 hours continuously, circulation fill, discharge three (consult battery maintain first) by waking the new battery up completely totally, if the battery deposit several months, propose, go on complete filling, discharging 3 times to it too. If one battery still can not be charged after the 12 hour or three circulations this battery can not use needing to change.

Knowing the information above, while use the machine we should pay more attention to these items 1 try to fully charge and discharge the battery while using the machine. 2 Fully charge and discharge the battery once every two months. 3 If there is problem about the battery, our advice is pls try it by yourself first or contact to the service center to examine the battery.

Here is some information about laptop batteries I have compiled over time after searching a lot about it on the internet. This information applies only to lithium ion batteries. Pretty much every laptop being built these days uses this type of battery.

1) Li-ion batteries have a life of about 400-500 recharge cycles, or about 3 years, whichever comes first. After that, they don't work at all, or too poorly to be of any use.

2) People who have been using laptops since the days of NiCd batteries are used to having to fully discharge their batteries before charging them. You should not do this with Li-ion batteries, this will actually reduce their life. However, you should still discharge them fully every 50 charge cycles or so, otherwise the battery may not report the correct amount of charge remaining in it.

3) The number one killer of Li-ion batteries is heat. Storing batteries in hot places (like a car in the summer) for long periods of time will reduce their life. Also, if you're using your laptop on AC power and the battery is fully charged, it is better to take the battery out of the laptop than leave it in, due to the heat. But do not let dirt or dust or whatever get in the laptop where the battery goes.

4) If a Li-ion battery will not be used for a long time, it is best to store it with 30-40% charge remaining. Then when you need to use it again, charge it fully before using. Also, store it somewhere where it's cool. One website even recommended storing it in your fridge (but not the freezer).

5) Although it should take about 3 hours to fully charge a laptop battery, the majority of the charging happens in the first hour. You might notice your battery charges up to about 90% pretty quickly, but then it takes a really long time to charge that remaining 5 or 10%. It is not harmful to the battery to not charge it all the way to 100% every time if you don't want to (although when it's new, you should charge it to 100% the first 3 or 4 times to break it in).

There is no standardization of laptop batteries, so once a battery dies, you will have a difficult time finding a replacement because a battery from one laptop brand will not fit into another laptop. So your only source of a replacement is your manufacturer, however by the time your laptop battery is old enough to not work, your manufacturer will probably have stopped manufacturing the type of battery you need a long time ago, and even if they have some batteries remaining to sell you, the batteries will not last as long as new batteries because Li-ion batteries only work for about 3 years after they are built. For this reason, some people are pushing for a standardization of laptop batteries, ie for all laptop manufacturers to design batteries of the same size and shape so that one will fit all.
