The laptop’s performance and function, individual manufacturers have been constantly developed powerful laptop system stability, in the hardware design, more and more human, but an expensive laptop, the battery performance and use is often ignored users, when the battery problem happened when the use to care about their use and maintenance problems. In fact, the use of laptop battery should be strengthened more use of the concept, we will not be wronged many flower money to buy a new battery. Books in order to allow the main people to be able to gain a better understanding of all aspects of notebook batteries, and the author himself in this experience to share with you. After all, the price of laptop battery is still very expensive, accounting for the overall price of the notebook’s 10% -15%, the battery also be regarded as consumer goods, the use of a good battery is also tantamount to save money.

Notebook batteries
Notebook battery types and materials:
Laptop battery for use in four main categories: 1. Ni-Cr Battery [Ni-Cd Ni-Cd], 2. Ni-MH Battery [Ni-MH Ni-MH], 3. Lithium batteries [lithium electricity Li, Li-ion Li-ion, Polymer lithium secondary Li-polymer], 4. fuel cells [Alkaline FC (AFC), phosphoric acid-type FC (PAFC), Molten Carbonate FC (MCFC), Solid Oxide FC (SOFC) and proton exchange membrane FC (PEMFC), etc.]
Nickel-cadmium batteries (Ni-Cd)
The first laptop to use nickel-cadmium batteries are (Ni-Cd), because of battery technology was not advanced nickel-cadmium batteries have a lot of people headaches disadvantage, such as: bulky, heavy weight, the capacity of small, short life, has memory effect, etc. (give me the impression that no one branch). I have no doubt that notebooks are pursued with the lightweight, fast and runs counter to the performance. At present, nickel-cadmium batteries have been eliminated, and nickel-cadmium notebook also break, and again it is not much need to.
Nickel-metal hydride battery (Ni-MH)
Nickel-metal hydride batteries are currently the most environmentally friendly batteries, pay attention to environmental protection, countries have strongly advocated the use of nickel-metal hydride batteries, because easy to recycle, and damage to the environment is also the smallest. However, nickel-metal hydride batteries with lithium compared to electricity, or have some disadvantage. Long charge time, weight than Shen capacity than lithium-electric small, there is memory effect. Although the memory of it, unlike nickel-cadmium battery so much, but still need to discharge, the user must be exhausted before recharging. However, Ni-MH rechargeable battery number can reach more than 700 times, some good quality product charge and discharge up to 1200 times longer than lithium batteries and the price is also very popular.
Lithium batteries (Li), lithium-ion battery (Li-ion), lithium polymer rechargeable lithium-ion battery (Li-polymer)

Lithium electricity
Lithium electricity, there will be a long time ago, when it is not safe when used often in charge when burning, burst, and this is perhaps too active, because the element lithium reasons. Later there will be a improved version of the lithium-ion battery (Li-ion) add the element lithium can inhibit the active ingredients, which are alternative to lithium batteries, and its possession of the anode used to suction the carbon lithium-ion discharge, the lithium into lithium-ion, from the battery anode, lithium-ion battery cathode arrival. Charging, the cathode in the lithium atom ionization into lithium ions and electrons, and lithium-ion to the anode and e-sport synthetic lithium atom. Discharge, the lithium atoms from graphite crystals within the anode into the surface ionization of lithium ions and electrons, and cathode Department synthetic lithium atom. Therefore, in the lithium batteries to lithium-ion Forever the form, not the form of lithium, of course, it will not appear combustion, explosion, and dangerous. Lithium-ion in the move between the anode and cathode, the electrode itself does not change. This is a lithium-ion batteries and lithium batteries are essentially different. So that the lithium electricity really achieve a safe, efficient, convenient, and the old electric lithium also eliminated. Ways to distinguish between them is quite simple: from the logo on the battery will be able to identify the logo for the electric lithium Li, and Li-ion battery for Li-ion.
Lithium Polymer rechargeable lithium-ion battery (Li-polymer) is that in this at least three main structure has one or more polymer materials used as the main battery system. In shape, the polymer lithium rechargeable lithium-ion battery has a thin shape and size can be arbitrary and can be of arbitrary shape, such as a number of advantages, so it can accommodate product demand, resulting in any shape and capacity of the battery. In thickness, the polymer lithium secondary battery is about the thickness of 2 ~ 4mm, and the current lithium-ion battery is the minimum thickness of 6mm, can be reduced by at least about 50% of the thickness, can achieve the minimum thickness of about 0.5mm.
Now, notebook and mobile phone use the so-called lithium electricity, in fact, lithium-ion battery. Lithium-ion battery has a battery should not be compared to other advantages: high voltage; small size, light weight, high energy; safe fast charging; permit wide temperature range; discharge current small, memory effects of the small (now some of the view that lithium-ion battery completely no memory effect, which is a not responsible for that), no environmental pollution and so on. Of course, lithium-ion batteries also have their own deficiencies, that is, high prices, charging less (the number of charge and discharge it only 400-600 times, specially to improve the products, however many times 800. Recharged once per day basis, the best However, the lithium battery is also more than two years on a laid-off.), with no interchangeability of batteries, voltage changes, firing rate, and capacity decreased rapidly, not large current discharge.
Fuel cell
How to make laptop longevity – notebook battery maintenance skills
Fuel cell
Fuel cell [Alkaline FC (AFC), phosphoric acid-type FC (PAFC), Molten Carbonate FC (MCFC), Solid Oxide FC (SOFC) and proton exchange membrane FC (PEMFC), etc.] is a chemical battery, it use of substances when the release of chemical reaction energy directly to electrical energy conversion. From this point of view, it and other chemicals such as manganese dry battery cells, lead-acid batteries, etc. are similar. However, it is the work required to continuously supply active substance (the substances react) – fuel and oxidizer, which in turn, and other ordinary chemical batteries do not like. It is because of the fuel through a chemical reaction to release energy into electrical energy output, it is known as fuel cells.
Fuel cell by the three major components: the fuel electrode (cathode); electrolyte (what we call the “fuel”); air / oxygen electrode (anode). Initially, the electrolyte plate is the use of electrolyte infiltration and the formation of porous plate, and now being developed for the direct use of solid electrolyte. Job supply of fuel to the anode (hydrogen), oxidant supply to the cathode (air). Broken down into hydrogen at the cathode positive ions H + and e-e-. Hydrogen ions into the electrolyte, while the electronic circuit is shifted along the external cathode. Electricity load on the access in the external circuit. In the cathode, the air of oxygen with hydrogen ions in the electrolyte absorption arrived cathode electronic form water. This is precisely the reaction of water electrolysis process inverse. Take advantage of this principle, the fuel cell can be continuously at work to the external transmission. Batteries at work, fuel and oxidizer by external supply. Therefore, in principle, as long as the constant input of reactants, reaction products continuously excluded, fuel cells can continuously discharge. Both the non-polluting fuel cells, efficient, widely applicable, no noise and has worked continuously for the advantages of fuel cell by-product of job only water and heat, no noise, the basic pollution-free, efficient power system than the general much higher reached 43 ~ 58%, if the reaction heat generated also used, the efficiency can be as high as 80%! But on the other hand, are questions worthy of improvement, fuel cell costs are too high (fuel cell to generate hydrogen at low temperatures required for platinum catalyst is expensive, the cost of access to units of energy higher than the lithium batteries), a by-product of heat, as well as questions add fuel to obtain. These are to be further problems, but it is for the laptop battery painted a bright future prospects.
Therefore, the current battery, there is no perfect choice of battery. Requirements for different users can choose according to their own needs the corresponding types of batteries, of course, notebook manufacturers also make great efforts to develop a more robust portable battery.

Lithium-ion battery
Because now appearing on the market are the highest penetration rate of lithium-ion battery (Li-ion) Therefore, this article will focus on lithium-ion battery. Know your laptop battery you need to clarify the following parameters: battery capacity, rated voltage, the normal use temperature.
Capacity by the size of the main marked mAh from the battery to determine its Chinese name are milliamperes. MA when the size is directly related to the use of laptop battery time, but it can not be generalized. Laptop battery does not mean that the capacity of the supply of bigger and more lasting use, the actual ability to use the process of life are closely related to the notebook power consumption. Everyone can imagine a laptop to configure the greater the higher the energy consumption, operation of computing the amount of electricity the greater the speed of passing it sooner.
Normal operating temperature of the battery are to normal working temperature range, in the use of non-normal temperatures may have a dangerous (explosives), as well as unnecessary troubles (leakage, sudden power outages).
Production date, which in some older models of laptop battery will appear, which directly shows this battery you can use the length, it is decided to use a normal battery time is very important parameter. So we buy a notebook to pay attention to it when the battery manufacture date, even if the new battery placed on a longer period of time his life would have a corresponding reduction. Buy second-hand books for the expectations of the users should pay attention to the parameters.
How to tell what the parameters of this battery? From the above picture we can see the type of battery used for the Li-ion, lithium-ion battery that is. Rated output voltage 10.8V, electricity 4800mAh. Of course, manufacturers have also, production, the normal operating temperature (0 degrees -60 degrees) and so on, batteries are currently in such a logo, everyone can enlarge the picture above, go about their notebook battery to some of the basic situation.
Notebook battery for external structure we can only look at some of the above parameters, the internal structure of trust many people are “not daring” to understand. After all, the price of laptop battery or be called expensive.
In fact, the essence of notebook batteries and ordinary rechargeable batteries are not like, but major manufacturers have their own models for the appearance of a battery casing of processing, so that if the ripping out of the shell laptop battery, its internal structure and ordinary battery pack there is no distinction, in other words mutual constraints common major brand notebook batteries are the biggest obstacle of all major laptop brands among independent design.

The internal structure of the battery

The internal structure of the battery
A closer look at the internal battery, which is actually several sets of batteries are series-parallel circuit, in general, by a single laptop battery battery capacity and voltage requirements of the constraints, generally use the laptop battery after the first series of parallel approach to ensure its operating voltage and battery capacity, an analogy, if we say that a nominal 12.5V, 4000MAh notebook batteries, in general are so constituted: the first three single voltage 4.2V, 2000MAh batteries in series, to achieve its 12.5V nominal voltage, then through a group of the same cell and then the composition of parallel circuit, the battery’s overall capacity to 4000MAh, this battery is generally said to 6CELL battery pack.

Six-cell battery
Laptop battery for the internal and external, as well as the principle power supply has a certain amount of understanding, we can better in their daily work, the use of notebook battery life. Then talk about the author himself in the laptop battery for some of the experiences and suggestions.
First of all, got a new battery, many users approach is in accordance with the business prompted the use of lithium batteries in the first three charge 12 hours or more. This line also has a lot of controversies, but in actual use I found, in fact, that for the majority of notebook batteries are not necessary. Why? Say yes to do business this way in order to fully activate the cell activity, a new battery fully awaken. For this reason it sounds very full and credible, but the U.S. has not thought about this question. If, notebook battery vendors have not yet been fully activated on the appearance, such products can be said that only a semi-finished products. Can not require each user to master the skills to activate the battery, it is impossible in reality. Therefore, in the battery factory has been a manufacturer of fully activated. How are users 12-hour rechargeable battery is conducive to the use of it? In this I give a negative answer, the current notebook batteries have improved power management circuit and charging management system, when the battery reached saturation, the control circuit automatically switches to short-circuit state, so after the time is merely a waste of time only. How can we activate the activity of this battery? In fact, the vendor for battery overload protection in the absence of activation is the case of the battery charge and discharge time. Therefore, charging the three previous 12 hours is unnecessary.
In the second, many users use the battery very confused, what should not wait until the battery is fully depleted before recharging. In fact, this question should be answered is that if you can make sure this is a good thing, but the premise is that you too troublesome. Of course, I am talking about here is not referring to the excessive discharge, Practice has proved that excessive battery discharge is harmful, it will shorten the battery life. Thus, when the notebook prompted a time of low power consumption can be a timely charge. Some business has repeatedly stated that its own lithium battery no memory effect, this practice is extremely irresponsible. So when your battery power when there is more whether or not to charge for the good, because memory effect does exist.
Third, for long-term battery should be how not to do, it is recommended 40-50% into electricity placed in the low temperature of the cool place, the following parameters to illustrate the problem.
Storage temperature of 40% state of charge 100 percent state of charge
0 degree 98% (a year later) 94% (a year later)
25 degrees 96% (a year later) 80% (a year later)
40 degrees 85% (a year later) 65% (a year later)
60 degrees 75% (a year later) 60% (3 months later)
(Percentage of saturation at the time the relative percentage of initial value)
Of course, the best month to come up with to use the battery once the battery can ensure a good state of preservation, but also not let the loss of electricity damage to the battery completely.
Fourth, in the laptop’s use of “the use of one month after the release should be a full-charge” approach is necessary. Li-ion laptop batteries are generally with the management of chip and charge control chips. Management chip which has a series of registers, there is capacity, temperature, ID, state-of-charge, discharge frequency values. These values are in use will gradually change. Personally, I think, in the laptop’s use of “the use of one month after filling the whole place should be a” major role in the practice should be amended is inappropriate in these register values, making the battery charge control and battery nominal capacity in line the actual situation. So it should not omit the job, after all, high-priced notebooks or aristocratic effemination.
Finally on the use to talk about, how to make books more lasting battery. Now that you bought a notebook is to use it, batteries are one of consumables, bound with an extension of time towards retirement. How to make books a longer battery life? Power-saving technology? Hibernation? Let the hard disk hang? So that the screen brightness decreases? Are various ways seems to be able to increase the so-called time. But you have not thought about, so that a meaningful extension of the time it? Open books I do not run any programs, do not open display, not the hard disk turn, I can not reach a longer period of time. May think this absurd practice, notebooks are used to use, rather than high-sounding setting. The author therefore suggests that the U.S. make good use of the notebook rather than about how to use the notebook. Perhaps, after two years of the notebook market is another heaven and earth, your books have reached the ranks of retired. U.S. attention to the battery as long as day-to-day usage, the normal battery can be used, they can no need to be indecisive.
