Books battery maintenance tips 2
Normal working temperature of the battery can work temperature range, the use of non-normal temperatures likely to be dangerous (explosion), and the unnecessary trouble (leakage, a power outage). Production date, which in some older models of laptop batteries will appear, it is a direct reflection of your piece of the battery can use the length of time, which is to determine the normal use of a battery time is very important parameters. So we buy a notebook it is time to pay attention to the battery of the production date, even if the new battery put a longer time of his life there will be reduced accordingly. For users who want to buy second-hand books is the parameter should pay attention to this area
Exactly how to distinguish the parameters of the battery does? From the above picture we can see the battery category used in Li-ion, toshiba satellite a70 battery lithium-ion battery that is. Rated output voltage 10.8V, capacity of 4800mAh. Of course, there are manufacturers, production, the normal working temperature (0 degrees -60 degrees Celsius), at present, the identity of such batteries are used, we can enlarge the picture above to learn about their notebook battery some basic information.
For the books of the external structure of the battery we can only take a look at some of the above parameters, the internal structure of I think many people are “afraid” to understand. After all, the price of laptop battery, or be regarded as expensive.
In fact, the nature of laptop batteries and rechargeable batteries do not have two normal samples, but the major manufacturers have their own models for the appearance of the battery case processing, so that if the peel laptop battery shell, its internal structure and ordinary battery does not have any difference, that is the major brand laptop batteries and checking the other GM’s biggest obstacle is the major brand notebook computers between the independent design
A closer look at the internal battery, which is actually several sets of batteries series-parallel circuit, in general, by a single laptop battery battery capacity and voltage constraints required, notebook batteries commonly used in parallel after the first series of approaches to ensure its operating voltage and battery capacity, an analogy, if a nominal 12.5V, 4000MAh notebook batteries are generally composed of this: the first be three single voltage of 4.2V, 2000MAh on batteries in series, to achieve its 12.5V nominal voltage, and then a group composed of the same cell and then parallel circuit, the battery’s overall capacity to upgrade to 4000MAh, this battery is commonly referred to the 6CELL battery pack.
The internal and external batteries for notebook computers as well as the power supply has a certain understanding of principles, toshiba satellite m100 battery we will be able to better work in their daily life batteries used in books. Then talk about the author himself for the notebook computer batteries in the use of some experience and recommendations. First, got a new battery, many users approach is in accordance with business tips in lithium batteries used in the previous three or more of charge 12 hours. In this connection, there are also many online debates, in fact, that for the majority of laptop batteries is not necessary. Why? Businessmen say this was done in order to fully activate the activity of the battery is completely wake-up a new battery. For this reason it sounds very full and credible, but we have not thought about this problem. If, laptop battery manufacturer has not yet been fully activated on the appearance, then this can be said that only a semi-finished products. Can not require each user to activate cells to master the skills, in reality impossible. Thus, in the battery factory has been in full activation of the vendor. How are users 12-hour rechargeable battery is conducive to use? Here I give a negative answer, the current laptop battery has improved power management circuitry and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit state, so a later time is merely a waste of time only. How can I do to activate the activity of the battery? In fact, the vendor for the activation of the battery case in the absence of overload will be a long time the battery charge and discharge. Therefore, the first three charge 12 hours is unnecessary.
In the second, many users use the battery very confused, what should or should not be charged until the battery is fully depleted. In fact, answering this question should be like this, if you can do that is certainly a good thing, but only if you have too much trouble. Of course, I mean talking about here is absolutely not over-discharge, toshiba satellite m55 battery over-discharge is absolutely proven harmful to the battery, it will shorten the battery life. Thus, when a low power consumption when the notebook prompts can be a timely charge. Some merchants have repeatedly declared their lithium batteries no memory effect, this practice is extremely irresponsible. So when you have more power when the battery is not charging for the good, because the memory effect does exist.
Third, for a long time without the battery should be how to do, it is recommended into the 40-50% of the electricity, placed in the cold shade, the following parameters illustrate the problem.
Storage temperature 40% of the charge state of 100% state of charge
(0 degree 98% (one year later) 94% (one year later)
25 degrees 96% (one year later) 80% (one year later)
[40 ° 85% (one year later) 65% (one year later)
60 degrees 75% (one year later) 60% (3 months later)
(Percentage of saturation at the time the relative percentage of the initial value),
