It is the advantage of lithium-ion laptop battery to enjoy recharging and portability with little memory effect. Under this circumstance, if you can take good use of these laptop batteries, it will be a great honor for you to become master-hand and get more amazing effects from your laptop computers.


As is known to all, the laptop batteries are composed by shells, lithium-ion cells and protection circuits. Generally speaking, cells quantity is indicated in the specifications of laptop battery that can show us about the output power, voltage and electric current, figured by Watt, Volt and mAh.


internal structure, laptop battery

The internal circuit consists of protection circuit, also called secondary protection circuit, and capacity instruction circuit. It is produced to handle with the charge-discharge and security.


The standby time is determined by the value of mAh. In most cases, the quantity of lithium-ion cells can show us the value accurately according to the properties of sole cell. And the lifespan of laptop batteries are determined by the cells recharging cycles.

Except for the characteristics of lithium-ion laptop battery, it is of great significance for users to master some unique usage skills.


Enter into sleep mode more rapidly. If possible, we can adjust to reduce the standby time before entering into the sleep mode, which can not only save more power energy but can optimize the performance as well. In addition, we are also able to get into sleep mode directly by closing the LCD screen. Please figure out the switch button of laptop screen and you can get more useful power energy.


Speaking of the laptop LCD screen, diming the screen is supposed to be the most common way. According to the research, the value between 6 and 8 is regarded as the most reasonable range. In BIOS, there’re also several energy-saving modes for your reference, such as Standby Mode of Idle Mode. So, please read the indicating information on the screen seriously.


At last, something in regular use has also related to the performance of rechargeable laptop batteries. For example, we can set the alarming mode to increase or reduce the alarming time while most of users prefer to 10% remained. If possible, please activate your laptop battery by charging and recharging for several times. I believe you will be a master-hand rapidly if you have acquired and figured out your own unique usage method in your daily life.

Ni-Zn laptop battery is rare in the market while we can only find Ni-cd, Ni-mh and Li-ion ones. As a matter of fact, Ni-Zn has already been taken advantages in other electronic products, such as digital camera and some battery-operated toys. However, it is really a hard nut to crack so that some Japanese manufacturers who have achieved significant results before decide to give up.



In fact, a century ago, Thomas Edison has realized the potential power of Ni-Zn batteries and conducted a study. Limited by technology, he hasn’t well developed and then Ni-cd and other metal hydrides become commercialized successfully.



According to analysis, Ni-cd batteries are bad to environment and died out for its memory effect. Some periods later, Ni-mh battery is influenced by hypertoxic problems and passivation phenomenons even if less memory effect exist.



At the beginning of last year, a little-known American company Power Genix announced the launch of brand new Ni-Zn rechargeable batteries. Since such an old technology is refurbished, especially in improving electrolyte and electrode formula, they are concerned by others in further generalization and actual performance.



Ni-Zn laptop battery has higher output voltage due to the powerful cells. In the past, Grade AA cells can only reach 1.2V while that is Ni-Zn ones are of about 1.6V which is appropriate for those consumer electronics of 1.5V. Meanwhile, they won’t produce much more heat than former conditions.



Since Ni and Zn are both metals easily to be recycled, this sort of laptop batteries will be more environmental friendly.



Despite of powerful functions, Ni-Zn laptop battery is still in the process of researching even if it hasn’t been popularized in other areas. Electrolyte and cells structure are the present objects in the market.
