laptop battery damage

Although it is easy to be connected to the ac adapter, the laptop battery has suffered from many unexpected problems. Usually, you may ignore the effect of the battery. It is until the damage occurs that you begin to think about it. In order to facilitate all of you here, we’ve summarized the questions which were constantly asked by our customers.


If my laptop battery hasn’t discharged entirely, will it reduce the life span?


The battery life is primary determined by the recycling circles. For the li-ion battery, the number is about 400 to 600 while a special one with the circles of nearly 800. Although a little memory effect exists, the influence of the memory effect is far inferior to that of the natural loss.


Why is it not until the indicated remaining time that the laptop powers off by itself?


The problem may be related with both the power indicating software and the laptop battery. You replace the battery with another to check if the problem emerges. If so, there must be something wrong with your software.


How long is the standby time of the laptop battery?


It is really hard to say. Even if with the same battery for dell inspiron 9300 laptop, the condition differs from each other. On the one hand, the standby time is related to the battery specifications; on the other hand, it will be reduced by more running programs. It can be calculated by the battery dominant power and the actual current. If you really want to extend it, you can carry out some actions on the laptop, such as dim the screen, remove the hard disk and so on. Furthermore, a higher capacity compatible laptop battery is a good choice.

expensive laptop battery, expensive ac adapter

Both the laptop battery and ac adapter are expensive articles of consumption, which has attracted a lot of disputes.


With the popularity of laptop computer, many problems about it come in pairs. All kinds of statements about the correct operation of it are common, which are different from each other. With many years of experience, we have summed up some points of them.


Is the activation necessary to a new laptop battery?


For one thing, the new battery is with 3% power energy remained. It should be fully discharged until shutting down and then recharged by an external power supply. The process of activation must be repeated for three times while the charging time must be more than 12 hours.


For another, it is no need for a li-ion laptop battery to be activated by a more than 10-hour charging.


Indeed, the latter point is closer to the truth. The result of an official experiment shows that more than half of the laptop batteries are in good condition while they were charged for only two and a half hour in the first use.


Suggestion:


It is reported that the manufacturers have completed activation of new laptop batteries. It is to avoid the damage of discharging that a little power remained. The process of activation cannot be achieved when it is under the work of protection circuit. For li-ion batteries, such as battery for dell inspiron 9300 laptop, once they are fully charged, the indicator lights die out and no more power will be provided.


There’s a simple way to check if the battery is in the process of charging. When there’s some electric power flowing from the adapter, the battery must be hot. However, nearly one hour after indicated to be fully charged, you’ll find that the battery is extraordinary cool. The fact has shown the all.

For most users, it is useless to charge the laptop battery to 100%. In normal, the remaining power always varies from 20% to 98%. The protection circuit in the battery takes effect when it comes to be about 98%. Therefore, the condition of overcharging can be avoided.


Practicly, overheat caused by overcharging is dangerous, which is said to be the primary factor to the laptop damage. Supposed a dell laptop battery charger continues to provide power to the dell laptop battery without the effect of the protection circuit, what will happen to the battery? To some extent, for a laptop battery, it should attach great importance to the circuit instead the cells only.


You may have experienced that it is not until the indicated standby time that the laptop comes into the state of auto sleep. It cannot put the blame on the battery only, which may be caused by the damage of the indicator software. The problem should be checked carefully, or it won’t be fixed thoroughly.


If the standby time decreases rapidly or it is much shorter than usual, there must be some damage to the laptop battery. You can conduct a calibration method to your dell laptop before purchasing a new dell laptop replacement battery.


The way to regulate is that discharging fully and recharging for nearly 3 times. Usually, the battery will bring back to life even if it is not so good as a new battery for dell inspiron 9300 laptop.


In early times, many dell laptop batteries are Ni-cd batteries which need the calibration at least once a month. Actually, a li-ion laptop battery still has a little memory effect. The method can make the battery worn out slower.


Briefly, the laptop battery charging is not only the business of charging in the use, but the activation and maintainance as well. The correct way to charge laptop battery is an art with profound skills.

Laptop, with a small appearance, is a portable computer which is only 2-6 pounds. With time goes by, development trend of laptop is smaller in size, lighter in weight, more powerful in function. The new released Netbook, with the additional function and compact shape, is very popular.


Compared to the desktop computer, their basic structures are the same, which are LCD screen, keyboard, mouse, CPU, internal memory, hard disk and laptop battery. However, the advantage of laptop are obvious, that is, portability. Whether it is on a business trip or on travel, laptop can be carried to anywhere as you like.


Like other high-tech products, a laptop computer costs a pretty penny. It is the advanced technology that makes a laptop updated rapidly. Thus, it is impossible for everyone to own the latest type of laptop. For many users, the best way is to update the system by themselves, such as update from Windows xp to Windows 7. But do you know that some accessories should be updated with it, such as internal memory and ac adapter for laptop.


As is known to all, laptop can be divided into four types by function, that is, business, fashion, multimedia, other models for special purpose. Users can choose the suitable one for themselves without considering of the configuration seriously. Nevertheless, have you considered that if your former battery for dell inspiron 9300 laptop is fit to the new dell laptop? If so, except for cost saving, it will benefit you a lot. Supposed there’s a emergent business trip tomorrow, the battery will provide you more work time in the airplane or any other places without socket.


It can be checked from the compatible laptop model lists of a certain battery in our website. So does the ac adapter. Without them, laptop won’t be so convenient as it is.

As we all have seen, laptop battery is indicated by volts(V) and milliamps(mAh), which is designed specially for the laptop. Volts(V) and milliamps(mAh) are connected with power rating and consumption. Therefore, knowledge of these parameter could avoid you from miss bought and battery damage.


A power rating of laptop battery exposes the standby time of your battery and information about replacement. Volts(V) and milliamps(mAh) are specification parameters to the battery. For instance, battery for dell inspiron 9300 laptop is rated at Li-ion 11.1V and 7200mAh.


Laptop battery measures the energy situation, reported by Volts and milliamp hours. Volt(V) is measured by the voltage of two electrodes, which is related to the voltage of power charger. Amps(A) is measured by electric current from battery to laptop, whose energy could influence laptop procedure.


Like streams, volts and amps continuously flowing although no destination for them. However, if there’s a resistance on the other side, more voltage will be produced just as laptop power-on. Quantity of running applications are still concerned with power energy, for more applications need more energy. When playing an energy consumption application, such as a DVD, more power will be produced.


The capacity of laptop battery is the determining factor of power rating. The rate of flow can be control by laptop automatically, which is regulated by amps. Normally, volts and amps are allocated fit to the laptop models. It’s no need to collocate a high capacity

for convenient use, which may cause damage of laptop or even worse.


Furthermore, to read the explanation and guidance of laptop battery is necessary. You can check your laptop model in the list of compatible parts number for appropriate battery. In addition, it should be performed diversely by different forms, such as toshiba laptop battery, such as battery for ibm t30 laptop, which will be published later in our blog.

Nowadays, li-ion laptop battery is common with advanced technology. It is said that the li-ion battery has advantage in capacity and performance. Compared to Ni-cd and Ni-mh batteries, it has nearly twice the capacity with only a little memory effect.


As to li-ion laptop battery, there’re several specifications exist while the capacity is different. For instance, battery for dell inspiron 9300 laptop is of 4800mAh while a compatible one can reach 7200mAh. In theory, a larger capacity, amp per hour, is equal to a longer standby time.


However, it is still needed to be fully charged at the first time of use. Although only a little memory effect exists, it is useful to be activated by charging for more than four hours. To be different, li-ion laptop battery cannot be discharged fully before recharging each time. If so, it will be damaged with the battery life shorted. Of course it needs to be discharged fully and recharged again for several times nearly once three months.


Furthermore, a stable ac adapter is necessary. It functions as the electric current exchange from 110V to the input current for laptop. The process is complex with several accessories of the adapter passed by. Moreover, the adapter supplies the power to both the laptop battery and the protection circuit. For these reasons, ac adapter holds a position of great responsibility. But it doesn’t mean that a cheap laptop ac adapter should be avoided. If you are right to buy a new replacement adapter, try to check the specifications and test the performance.


Just like laptop, batteries prefer to a cool and dry condition. If you are not going to use it for more than a month, removed it from the laptop and stored a sealed bag with the temperature of nearly 70℉. Besides, nearly 30%-40% power should be reserved in it.


To get a longer standby time, adjust to energy saver mode in power setting. A continuous running system will get the laptop to overheat which is also harm to the laptop battery.


In normal, the battery life depends on the recharging cycles. Nevertheless, if you maintain your li-ion laptop battery well, it will last much longer.

As is known to all, laptop computer is an electronic product with rapid update. For this reason, a used laptop seems to be more popular than ever? Are you just considering it? However, the factors like ac adapter and CPU are not easy to be tested. Or are you going to sell your used laptop? Are you clear about the actual value of it?


Here’s the list of factors you should consider before purchasing or selling. Some are the basic knowledge of the laptop which can be known from the seller or the Internet, while others are not. As the computer technology developed fast, especially for the new one, it is really hard to test. Besides, if it is an unpacked laptop, it won’t worth the expected value even if it is with a great allocation.


Laptop internal memory


Laptop internal memory is related to the running speed of laptop. In normal, the larger it is, the faster the laptop runs. If you are going to used Windows 7, a 2G one is the least. For Windows xp, 1G is necessary, or it won’t run smoothly. Certainly, a large internal memory isn’t supported by all the systems. For example, a 4G one is too large for Windows xp as it is limited by 2G. Certainly, for the sellers, a higher internal memory will get you a better price.


CPU


There’re two suppliers of CPU in the market, that is, AMD, Intel. Nowadays, the Centrino from Intel is said to be the best. Miraculously, it can also make the laptop battery last longer. And it has updated for several generations. If you occur to have a laptop with Centrino, no matter which generation, your laptop is still popular.


Warranty


For most laptops, the warranty varies from 1 year to 3 year. If the accessories happen to be damaged, it will save you a lot of money. In some places, an extra expense will get you an extended warranty. For example, in our website, a new replacement battery for dell inspiron 9300 laptop will cost you $66.24 while the option of 3 years warranty for only $39.95.


Usually, a private deal will provide you a good price. However, without the knowledge, you may lose a lot. Consider the above information seriously before making a deal. Otherwise, you’ll be disappointed about the laptop or the price. Wish you good luck in the deal.
