The nature of all laptop batteries refers to the device of the translation of its chemical energy, light energy, atom energy and other forms of energies into electric energy. Laptop batteries, generally speaking, can be divided into the primary battery, otherwise called the dry battery, and the secondary battery, that is, the rechargeable battery. With the rapid development of battery technologies, laptop batteries have by far experienced the initial voltaic battery, Ni-Cd battery, Ni-MH battery, the most popular Li-ion battery and the fuel battery representative of the development direction. If it is safe to say that CPU is the brain of a laptop computer, then no doubt laptop batteries are the heart of the energy resources of laptop computers.

The behavior of laptop batteries has a lot to do with the nominal voltage of a laptop computer. The nominal voltage can be divided into that of laptop batteries and that of laptop computers, which, overall though, are different from each other. The former refers to the voltage of the period of time when the retention time, during the decrease of the voltage of laptop batteries, of laptop batteries is longest in the process of their release of electricity. When the laptop is being charged while it is being used, or when it has just been charged, its voltage will be higher than when the battery is only being used. That’s why the labeled nominal voltage of laptop batteries is a little lower.


Of course there are certain technical skills which general users should not hesitate to learn, for a good maintenance of laptop batteries, but when batteries have been applied for some years or more to the laptop, it often requires higher technical methods for one to sustain their working qualities. The market of today features laptop batteries of Li-ion type which is currently the most popular among many users. It is essential for users to get to know three basic elements of laptop batteries: battery capacity, nominal voltage and normal working temperature. A good knowledge of how to put these three factors into correct application is indispensable to those who wish to have their batteries involved in proper functioning.


How to carry laptop batteries into correct application and extend their using time and using lifespan are often cared about by most laptop users. Provided that laptop batteries are fully charged, their working time can last for about two hours, which brings users a better opportunity to continue doing what they are doing before the laptop shuts down for lack of temporary supply of electricity. The performance of laptop batteries abounding with many using techniques and skills depends largely upon users’ correct ways of operation which are essential to the extension of the lifespan of laptop batteries. Most users are herewith expected to learn and apply these skills to laptops in their daily operation.


As methods of charging laptop batteries vary greatly from user to user, it is widely believed that no matter whether your laptop trades on a Li-ion or a Ni-MH battery, these batteries both have strong and remarkable memory effect. Comparatively speaking, the memory effect of a Li-ion battery is less strong than that of a Ni-MH battery. Now that the battery has memory effect, users will have to pay special attention to the moment when it is being charged. It is well suggested that users should not charge the battery until its internal electricity is used up, but it must be pointed out that they don’t really have to wait to charge the battery until the laptop shuts down automatically. In other words, it is not difficult for users to leave their charging of this battery to their own devices.
