Notebook laptop computer battery is necessary for users to use something, or when you need mobile office that can not use external power supply, all we need to use the laptop's battery, then how can better care of their laptop batteries to provide more long life time? Next, I will detail some information about laptop battery maintenance tips.
Now appearing on the market penetration is the highest lithium ion battery (Li-ion). Know your laptop battery you need to understand the following parameters: battery capacity, rated voltage, the normal use temperature.
▲ General laptop battery parameter information
Capacity, mainly from the size of the marked mAh battery to determine. MA when the size is directly related to the use of laptop battery time, but it can not be generalized. The capacity not to say that the greater use of laptop battery time will be longer, in the actual process of using and battery life are closely related to the notebook power consumption. General configuration of the next higher power consumption laptop necessarily greater, the greater the amount of computing power to run the faster passage.
▲ 7800mAh high capacity laptop batteries
Rated voltage is divided into notebook and laptop batteries rated voltage rated voltage, generally there is a certain difference between the two, the former refers to the process of laptop battery discharge when the battery voltage drops to stay the longest period of time the voltage. Notebook while in use or while charging just been charged, the battery voltage is higher than when using only the higher. Therefore, the rated voltage marked on the battery to be slightly lower.
▲ In the notebook notebook adapter marked with the rated voltage
Normal operating temperature is the temperature of the battery can work scope, the use of non-normal temperatures may be hazardous (explosive), and unnecessary trouble (leakage, a power outage), generally the battery in the course of this rarely occurs case, but users do not use the effect to prevent the dell laptop battery close to the hot or cold objects.
How to distinguish whether the battery parameters? From the above picture we can see the type of battery used for the Li-ion, that is, lithium-ion batteries. Rated output voltage of 10.8V, battery is 4400mAh. Some batteries will also mark the manufacturer, producer, the normal operating temperature (0 degrees -60 degrees Celsius), at present, the identity of such batteries are used. We can see the basis of these identify their laptop battery specifications.
In fact, the nature of laptop batteries and ordinary rechargeable batteries no different kind, but the major manufacturers have their own models for the appearance of the battery case processing, so that if you peel the shell laptop battery, its internal structure and common There is no difference between the battery pack, that mutual constraints common major brand laptop batteries notebook computer is the greatest obstacle between the major brands of independent design.
▲ different manufacturers design the appearance of different laptop battery
After the demolition of the laptop battery with an ordinary dry cell batteries, and there is not much difference, described by the following, I hope you have a laptop battery for deeper understanding.
▲ traditional internal structure of the 6-cell battery
▲ laptop battery control circuit
A closer look at the internal battery, this battery is actually several groups of series-parallel circuit, in general, by a single battery notebook battery capacity and voltage requirements of the constraints, notebook batteries commonly used in parallel after the first series of measures to ensure its voltage and battery capacity, analogy, and now most mainstream 12.5V, 4000MAh laptop battery, generally so constituted: the first by three single-voltage 4.2V, 2000MAh batteries in series to achieve its nominal 12.5V voltage, then a group composed of the same cell and then parallel circuit, the battery's overall capacity to upgrade to 4000MAh, this battery is generally referred to the 6-cell battery pack.
▲ general arrangement of 6-cell battery
Described by so many, I believe we laptop battery for some of the parameters and the structure has a certain understanding, then the next we will send you laptop maintenance methods and proper use.
For internal and external laptop battery and power supply have a certain understanding of the principle, we can be better in their daily work, the use of sony laptop battery life. Next, introduce some battery life for notebook computers in the tips.
▲ laptop batteries in different shapes but the basic principles of composition similar to
First, get a new battery, lithium battery is the way many users use the first three charge 12 hours or more. This approach, there are many online debates, businesses that do so in order to fully activate the activity of the battery, fully wake up a new battery. For this reason it sounds very full and reliable, but we have not thought about it. If the laptop battery manufacturers have not yet been fully activated on the appearance, then this can be said that only a semi-finished products. Not require each user to activate the battery to master the skills, in reality, impossible.
▲ The first three charge and discharge laptop batteries to be sufficient
However, this approach but it is still necessary, not because of the above reasons, but because of its notebook batteries activated there will be natural in the process of discharge, as is generally required after the factory had some laptop time to buy, after natural discharges, The battery is significantly lower than the factory, then, when you need us just after buying the laptop for the discharge of its work, should not shine all the power, remained at around 5% you can plug in the power of battery charging, so repeated three times, you can effectively eliminate the battery memory effect.
Again, many users use the battery very confused, what should or should not wait until the battery is completely discharged before charging. In fact, answering this question should be like, if you can do is certainly a good thing, but only if you took the trouble. Of course, I have here said is not referring to excessive discharge (battery less than 3%), proved over-discharge the battery is definitely harmful, it will shorten battery life. Therefore, low power consumption when the notebook tips when you can charge a timely manner.
▲ When the remaining battery charge is not recommended when more
Some businesses have repeatedly declared their lithium batteries have no memory effect, which is misleading to say. So when you have more power when the battery or not charging as well, because the memory effect does exist. Memory effect is leaving the battery with the battery because the contents of a crystallization effect. Usually occurs in nickel-cadmium batteries, lithium batteries for this phenomenon is not obvious. Occurs due to repetitive parts of the battery charge and discharge due to incomplete. Temporary capacity battery will decrease with time reduced. Develop good habits of charge and discharge is essential. Do not avoid excessive charging and the battery is fully satisfied electricity.
Third, for how long the battery should not do, it is recommended into the 40-50% of the electricity, placed in the cold shade, the following test data can illustrate this problem.
▲ the relative percentage of the initial value was the percentage of saturation
Of course, the best month to take the battery out with time, both to ensure the battery is a good state of preservation, they will not let the loss of damage to the battery power completely.
Fourth, in the notebook computer for use in "a month later should use a full charge and discharge" approach is necessary. Notebook computer lithium-ion batteries are generally charged with the management chip and control chip. Which management chip in a series of registers, there is capacity, temperature, charge state, the discharge frequency values. These values are in use will gradually change. Instructions for use in notebook computers in "one month after the full charge and discharge should be a" major role in the practice is to fix these registers should be in the wrong value, making the battery charge control and battery nominal capacity consistent with the actual situation.
▲ The new lithium polymer battery thinner shape
The last to talk with, how to make the battery longer books. Since you bought a laptop is to use it, the battery is one of a consumable, with the use of an extension of time will inevitably move towards retirement. How to make hp laptop battery last longer? Use of some power-saving technology? But this will certainly affect the laptop's operating efficiency and processing speed. This approach has no practical significance, the notebook is used to use, not for decorations. Thus Finally, I suggest you make good use of laptops rather than care about how to use the notebook. As long as we pay attention to the battery's daily habits, the normal use of battery.
