Teach you how to use the term out of laptop battery
Now more and more people use the notebook as a notebook lithium batteries, one of the main parts of the problems also increases. So how good use of the notebook lithium batteries do? Apple A1185 Battery Grasp the main points:
1. Appropriate charge and discharge current.
2. To minimize the discharge less than the charge or over discharge.
While the battery is a consumable, lithium-ion battery is no exception. But no one wants to use up the battery fine spirit of God, to what age do not even rattle is finished, no one wants to start his own half dead battery does not pull the living, has been rubbing on it in 2023, makes good sad to realize how the thing about you is not?
Well, get down to business, following the battery began to speak. First explain, only lithium-ion battery.
Appropriate charge and discharge current
General literature and the state standard on lithium-ion batteries on said lithium-ion battery charge current should be between 0.2C to 1C. It is said that the charge current battery capacity, such as your battery is 4AH, and then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge current should be between 0.8 to 4A. In general, the charge current at the extent permitted by the smaller the better, rechargeable lithium-ion battery should be the beginning of constant current charging, in my IBM R31, this current is about 2.8A, equivalent to 0.7C, is charging its own circuit control can not set yourself. Although this indicator does not charge more than the standard requirement, but is actually relatively large, especially when the battery capacity decline for some time after the charge current may be more than 1C. Laptop charging time is now also become targets regardless of the users, Dell Inspiron 6000 Battery manufacturers had to set such a high charge current.
So first step is to reduce the charge current. I have a friend in the lab, all equipment readily available, on trial with him a bit. Power outlet on the first series resistance try a result, current is reduced, but became intermittent charge, this is not a good thing. After repeated tests, 4 ohms is a more ideal value, this time around 0.8A charge current is very stable. This is only the current flowing through the machine power connector, battery charge current is estimated to larger, should be slightly larger than 0.2C. Specific to a different machine, this value may be different. Also with the increase in battery voltage, charge current will be smaller, but the decrease rate is small, less than 0.05A. In this charge state, charging circuit seems to not work, the battery indicator does not light. Etc. After the battery voltage up to 12.6V, charging circuits came into play and trickle charge the battery into the state, this time does not matter whether the series resistance has been, the charge current is controlled by the charging circuit, the last full charge after the charging circuit automatically end. The charging time is about 5.5 hours, if not resistance, charging time is 3.5 hours or so.
Lithium ion batteries are very delicate, good charge control circuit is required. With this charging method, can reduce the charge current, battery life, while use of the original books charging circuit controls the charge is relatively simple to achieve them, just buy a power plug (that plug into the notebook from power kind, the best to buy two, followed by the methods referred to still use one, be of good quality) and a resistor on it, pay attention to big head and little resistance, after all the above are about 2W of power Otherwise, it would be more heat resistance, preferably constant resistance of the wire myself one of the wire resistance and this resistance is independent of temperature. However, the shortcomings of this approach is obvious that, while not in charge of work with books. In addition, when charging will have a strange phenomenon, I do not write omitted here, and you try to know, Fortunately, this phenomenon into the trickle charge after the state disappeared. To extend the charging time is not a big problem, anyway, before the night began to charge, charge on a good day wake up, of course, if you are a night owl or a special short sleep time, that is another matter.
Small current charging problem solved, and now discharge problem. In fact, this is Fujitsu Lifebook T4020 Battery difficult, after all, the book is used to work, the discharge current will vary with the working state, the method mentioned here only designed to restore battery capacity of the operation.
Start the machine, set the power management will never go to sleep (standby) and hibernation (hibernate), others are set to the most power-saving modes, including CPU speed, turn off hard disk, close the display, etc., while in TP management process Close some unused hardware, such as sound cards, etc., and then open the battery status display window, allowed to run in the foreground! ! ! Close other programs, in particular, screen savers and other programs that run on time! ! Do not use the machine, do not close the lid, let the battery discharge end (not to discharge the minimum value set to 0, I established a 3%). Display and hard drive shut down, the discharge current is about 0.5A, this is my IBM R31 can be achieved on the minimum discharge current, battery discharge to the minimum value of the machine will automatically shut down after. The discharge lasted for more than four hours, depending on your battery capacity may be different in different, this time is also used to sleep way to send the.
Well, the last to emphasize that the method is not dead, especially discharge, 10 times which can be done once, or else why should the battery? Charge all the best with a small current charge, of course, if the need to use batteries, power cord plugged directly to the notebook on it.
Using this method my battery is now fully up 14 times, the capacity has been maintained in 45 more, the battery design capacity is 43.2, and has come down, but after such a charge and discharge are restored.
5, buy books must first determine how much you want to buy books, then what are you going to do with books.
Some friends wanted to buy books, but I do not know where to start. First, you have to decide is how much you buy books, is 12 “, 13″, 14 “, 15″ or larger. Size and price of books, the configuration associated with too great. Personally think that more than 15.4 “books, not as good as buying desktop, anyway, is not easy with you. Size you decide upon is the use of your books, your books this decision about what will be the configuration.
6, shop around, do not rush to buy; goods than three, do not hang from a tree.
Shop around, most people will do. But the goods than three, is also very important. Buy HP pavilion ZV6000 Battery books, it is best to do some advance preparation, a major model selected, while preparing for one of two alternative models. On their configuration, be aware of prices, then buy the better. At least if the business claims out of stock, you will not be him led by the nose.
7, buy books, pre-positioning and screening is the most important, detection is second.
The so-called positioning, that is, to what size your books (mainly the screen size, as well as body thickness and the like) and uses. Primary homework well in advance of purchase decisions are often more successful. How to buy books detection (roughly in order outer body appearance, serial number, screen, system information, hardware target), is also very important. Maybe you will not detect the hardware indicators, but the first few should have no issues now.
8, and the business of battle, the key is to be to know ourselves.
Said earlier, is how to do confidant. The so-called prophet, is to understand the technical capacity and JS’s usual response, in advance to be prepared. At the same time, the target current market price books, movements, whether discontinued, alternative products are already on the market and other issues immediately or should have some understanding of this information has just recommended the two sites have a lot of attention at any time can be the. As for the technical content JS, this forum has said a lot, and sum up, the most most important are the following.
9, refused to spot replacement.
Reported for the first low-cost business that is not available then, and then be recommended are not familiar with the models, a generous refusal, choose the alternative models; if it is true love, leave immediately. This is certainly prepared to you. Similarly, for a start, they reported a below-market businesses too much, do not just happy, business is not a fool, business has always Sony VGP-BPS2 Battery been prepared to fool you into Huyou. Be careful repair machine, converting machines like the trap.
