Since the topic of low-carbon lifestyle has become more and more popular, many people come to pay a close attention to the development in the technology of batteries. As a member of lithium-ion laptop batteries suppliers, I cannot help to think more about new investment and researches from outside world in this emergency period.



Above all, when more requirements of lithium-ion batteries get to the vehicles, it is no longer for laptop batteries to stay in the former position. According to continuous update of laptop and other electronic products, the traditional specification is unable to be enough to users.

It is reported that a new Gateway netbook has released with standby time of nearly 10 hours, which comes to be a high level to laptop batteries capacity. Compared to a standard Gateway mx8710 laptop battery, rated at 14.8 V and 4400mAh, the new battery has not much additional functions inside but less needs from netbook and components.



In fact, nowadays, users rely more on external Gateway laptop power cord instead of installed parts like Gateway mx8710 laptop battery. They even don’t want to remove the laptop to anywhere else while it has weakened the functions of portable electronics. In my opinion, it is not so good for laptop computer development, for which it is emergent for us to create great breakthrough to lithium-ion laptop batteries of great significance.



It is fortunate for us to see that many results in theory and practice have released in the market, including new electrode material and new technology in battery cells. Except for higher energy-to-weight ratios, I think more powerful performance in durability and environmental protection are bound to arouse a highlight in laptop batteries investment.

With time goes by, solar energy is more frequently used in laptop charger, some universal chargers in particular. Although this kind of new charger hasn’t been popularized so rapidly as we expected, we come to find out that it has really changed the industry of electronic products a lot by solar energy.

As a portable electronics, laptop charger with laptop power cord connected to external power supply has limited the usage of laptop computer in a certain place. Rather than relying on the AC adapter, many users who need to carry his laptop here and there have to fully charge their laptop batteries before going out, which has placed an additional burden on the users.



Then let’s have a look at the solar energy development and how much will it provide to laptop charger.



Convenient to carry – For most of users, what bothers them a lot occur to Gateway laptop power cord, especially for someone who raises pets at home. Even if Gateway laptop charger is good in performance and stable circuitry, universal charger works by solar energy seems to be more popular for it can be carried to anywhere as long as light is available.



Efficient to charge – With the development of solar technology, the utilization rate has improved fast to a great degree. Nowadays, we can use both light and heat to generate electricity for laptop charger, which has saved us a lot of other natural energy from the earth with more effective energy used for work.



Cheap to make – As these materials for solar laptop charger are available easily, it has saved the manufacturers more cost on internal structure materials. And compared to electromagnetic induction and pulse technology, solar energy is much safer with a huge developing space.



Limitation in technology – As many problems still remained in solar energy, especially to laptop charger, the technology of solar laptop charger is not so mature as we expected. But I believe that we will receive more additional functions to the consumer electronics from solar energy.

As we used to say, the charge speed is determined by AC adapter more than battery. When a Gateway laptop battery occurs to charge rapidly, more of users won’t pay attention to it while it may also be considered as the advantage of lithium-ion laptop batteries.



Thanks to the features of lithium-ions, more problems in Ni-mh and Ni-cd batteries have been solved, such as memory effect, higher energy density and lighter weight. For these reasons, it seems to be normal for Gateway laptop battery to charge rapidly. However, if it continues to be more fast while discharges slowly, is it still good to users?

Gateway mx8710 laptop battery, a li-ion one of 14.8 V and 4400mAh, is hard to charge rapidly for its output voltage comes to be higher than many others. In the process of charging, the voltage increases first and current follows. That’s to say, it is the voltage more than current that determines the charge speed.



However, how comes Gateway mx8710 laptop battery to be fast charged with no updates before? After checking by open-circuit voltage, I find out that there’re internal contaminants produced, including that of Gateway laptop power cord. As the later process of charge is only top-off charge, the part of voltage comes to be the primary contributor.



When internal resistances increase, those inside the cells in particular, the capacity comes to be reduced. The direct result is increasing the process of voltage charge and vice versa in discharge, just as the example of Gateway laptop battery. Although it is OK from the appearance, this abnormal phenomenon should be paid more attention to.

As to laptop power cord, nearly every laptop users has experienced to condition of falling down by the power cord. Similarly, have you ever considered that a poor quality laptop charger with poor contact in the interface will also be an obstacle in the path of your success?



Except for some solar ones, most of laptop chargers are designed with laptop power cord in both sides of the adapter. Gateway laptop power cord, for example, has prepared for certain distance between the laptop to the external power supply in the process of design and manufacturing.

As a matter of fact, too long or too short laptop power cord is neither good to users but the laptop charger itself. In the office, if complicated power cords exist there, it will make our staffs at high risk of falling down. If we choose to collect it by a concentrator, it comes to be influence on the internal circuit of the cord.



In addition, a poor quality laptop power cord is possible for you to wreck your career. Something has happened to one of my friends before that he used to summary the customer database and projects on his Gateway laptop. And one day, his colleague careless stepped on his Gateway laptop power cord, which led to his laptop power off suddenly and data loss to a certain degree. We can imagine the loss of my friend, his colleague and his company in both economic and mental.



And what I want to tell you is that the accidents are no more than that. As the power energy transmitted through laptop power cord, especially for the part from outlet to the adapter, it is with high voltage and current. Once it occurs to be open-circuit, someone who careless step on it may be electric shock seriously, which seems to lose more.



Therefore, please go for a high-quality laptop charger with good performance in laptop power cord. If you maintain the charger carefully, you won’t be a victim in the path of success.
