Laptop battery last for how long

After purchasing your notebook for some years the two years. Many users may have felt that Battery, began crying damn spoiled.

Stroke it, not sure if agree or not. Soon lost to me. Or lose it with age. So, did the life of the battery it ... Of course a few years



It is a notebook users often ask me that actually the battery life of notebook computers. How long lifetime, anyway.

Indeed. There are many different versions of the notebook battery. Brand. Each brand is. Will have a different quality to.

The quality of production. And the quality of materials used in the production of useful life is so different with the offline.

However, the average age of the laptop battery will stay at around 3 to 5 years old, depending on that Anyone lucky enough to have quality batteries.

Good little, it may last for up to six years than ever to find, but if someone without the battery quality. Or is counterfeit.

Just one year may keep the fire is not already offline, it is to the general, if one is available over three years, it is considered in

Criteria satisfied.

Notebook battery how not to wear faster.

Many questions about notebook battery. Or electronic equipment, various electronics. FAQs are being asked all the time. How to charge. No batteries to wear faster. How long to charge. Insert the battery or hunting that year. And many more facts. That many users still do not match today ITeXcite.com understand the answer to leave each other offline.

First, I must first understand that Batteries used in today is different from other batteries in the past. The features and maintenance. In the present Batteries are popular. Lithium battery type, which has two types.

1. Li-ion (lithium-ion): It was a standard battery commonly used in the present Is the most common battery.

2. Li-Poly (lithium-ion polymer): a battery that has been developed from the Li-ion power capacity increased by 20% and less constrained by the shape. Can be designed to have some more. But now there is a high price.

Many of you may have heard of techniques to charge the battery I understand lots of other matches before that. These methods. Batteries are used in older than Lithium, but as mentioned above, that Batteries used in the present is almost Lithium Batteries of this type. No matter how to charge charge charge often frequent or long the charger was a result of extended use very little battery so there's no need to pay attention to how the offline charging. But should pay attention to what to say the following instead.

Factors which caused deterioration Lithium battery.

1. When using the battery until the Cycle of beginning to lose normal self.

--- Cycle is a number indicating the number of charge cycles 1 Cycle is determined by the total amount of any charge. Was charging from 0% to 100% as if charging from 50% to 100% would mean 0.5 Cycle to recharge etc. do not mean the charging time is 1 1 Cycle quite.

2. Battery will gradually Decline by itself is already Since the production.

3. Charge / Discharge Rate.

--- Charge Rate is the rate charged on the amount of time a Discharge Rate is the rate of electricity consumption in one period. Consider the following table.




If the table is described as a simple language, it is charged with high currents. Fully in a short time, or the use of fire to run out in a very short time. Are a cause of Cycle decreasing lifespan decrease.

4. The temperature of the battery.

--- Temperature is another important factor that many overlook. If the environment of the battery to high temperatures. The battery will wear faster than normal.

How well will charge?

From these factors, the cause of the 4 main items. Lithium battery that caused the deterioration. Some of it preventable. But some of it indefensible It is based on lifetime. From those mentioned above. Enough to conclude a rough guideline. Lithium batteries for the following.

1. Recall that a Lithium battery that heat affects lifespan than the form or technique, so it should take care of charging the battery. Do not heat too much.

2. Avoid using the battery completely and then charge. Discharge Rate It enables a higher rate. Or the use of fire out in a short time. This results in decreased lifespan.

3. If you need to store the battery for a long time without being used. Should be charged at 40%, and then stored in a cool place. Enables longer lifetime.

4. Do not buy a Lithium battery to keep it available for use. Because this type of battery will degrade over time already. Since the production, so if you buy the store did not even use it yourself will decline anyway.

the Platform of the notebook.

The word platform (Platform) will be a familiar one to many people, especially if you are a person who is already in the field of IT with Probably heard this word frequently by a platform that is most relevant to the standards of electronic equipment, electronics things together today, we will talk about that platform in laptops. Or notebook together offline.

The meaning of the word platform is no standard format or standard of the production is made up of equipment And technology, many parts that work together.

The main platform for notebooks. That will be introduced to the 3 platform with offline.

Centrino.



Centrino is the name for many people may mistakenly think the name of the CPU, but actually you are Centrino platform. The Centrino platform has the full name of the "Centrino Mobile Technology", which has developed since 2003 with the intent to use with notebook computers. Features a power management more efficient. From the original equipment. Is similar to the desktop. The power consumption significantly for notebooks. And shortens the battery down. May have evolved similar performance PC, but can deal with energy efficiency. In that era Centrino platform very successful.

Components as a standard for Platform Centrino.

* Mobile processor Intel ® Core ™ 2 Duo.
* Processor Intel ® Core ™ Duo.
* Chipset Mobile Intel GM965 Express.
* Intel ® Next-Gen Wireless-N technology.

Centrino 2.



Problems in the Centrino platform, which is the subject of the GPU using a separate GPU is a major cause of power consumption is quite large. And cause heating. Despite the great power management of the Centrino whether this reason, we have developed defects. These and become Centrino2 sure enough.

The Centrino2 will be updated to better performance of the Centrino especially energy efficiency. The platform will use a intel CPU's codenamed Penryn, which use size 45 nm process technology from 65 nm to greater energy efficiency. The speed of the FSB is 1066 MHz The chipset and graphics card Wireless LAN will use the Intel ® GM45 Express Chipset and Intel ® WiFI Link 5000 series, respectively, are also developing systems for managing energy efficiency even more. Hybrid switching systems, such as for use with the split between the GPU onboard. This saves a lot of energy. Because when we do not use high level graphics. We can switch to the onboard video card. To avoid wasting energy is wasted.

Platform Centrino2 for the current version is named Montevina, which will have the following components.

* Next-generation Intel ® Core ™ 2 processor.
* Mobile Intel ® GM45 Express Chipset Family with Intel ® Graphics.
* Intel ® Next-Gen Wireless-N (Intel ® WiFI Link 5000 series).
* Intel ® 82567LM Gigabit Network Connection.

Puma.

AMD's latest is the cue to issue a new platform to consider buying each other offline. The platform is called Puma, which was officially launched then. The platform will focus on effective energy management. At the same time, it has the ability to display graphics in high-level as well. The ability of AMD has advertised are switching to use of the GPU (which was Eedhngr gone from Centrino2 of intel) connections from multiple monitors so that if you look overall, will focus on the answer to. use of multimedia is important.

Puma Platform components are as follows.


1. AMD TurionX2 Ultra contains the 3 models were.
- ZM-86 clock 2.4 GHz L2 cache 1 MB / core includes a 2 MB.
- ZM-82 clock 2.2 GHz L2 cache 512 KB / core includes a 1 MB.
- ZM-80 clock 2.2 GHz L2 cache 512 KB / core includes a 1 MB.

2. Chipset family R7.
The Puma will chip RS780 and southbridge SB700's new AMD will have IGP called HD3200 bundled with the chipset RS780 supports technology that is available in desktop fully both entertainment and functionality, while the HD3200. Avivo HD support is used for the repayment of CPU power to watch their H.264 and VC-1 fully

3. Wireless system that uses Atheros chips, chips that are used by the AR9280.

4. Graphics Card HD3000 family which consists of a HD3470, HD3670 and HD3870 respectively
