Cell phone lithium battery over-charging approach

You mention it, either because the relationship between buying a Big Nine, large and small Nine Nine cell battery is a model, as are the BST-38. When the boss bought a Big 9 sent a charger is estimated that cottage property or just a little sign, because I have not really seen, and there is no common parts loader. Go home with a moment, I feel pretty good, Dell Inspiron 1150 battery empty, almost more than three hours can be filled. Compared to the previous burden that small nine silent growl Jin (eight hours), this charger is clearly much higher efficiency. So I feel very good.

Result, the problem lies in this very nice top.

Watch the Big 9 Mody electricity, and I put a little touch of the nine panels replaced him, and then use it quickly washed into the nine large panels filled, and must post a small battery is almost used nine released and replaced by a good piece of charge. Then, quickly forgotten to recharge at night when they would be. Pricing of course, no hesitation, and took that fast red. Connect the middle of the night went to bed. Wake up. Time to see the blue light has been completed, and initially intended to overturn the result, too lazy to leave the cover to stand in the morning. Then yesterday night, to help small to 9 per battery, battery change is the piece of board. The results show a small battery-nine volumes of safe, suggesting that the lack of electricity, see the state of only 2% after the battery. Currently, I am a little sad. I forget to recharge? Do not think so continue to consider the red solid cap at the top, showing the burden of red light, I read it I thought, they did not load. (sorry for the four cells are not quite sure) just want to go to sleep, never imagined that after five or six minutes, which suggests that blue light filled, Maybe I know that this is certainly the Dell Inspiron 1100 battery there is a problem. So to win after nine charger with the previous small, taken in the progress of green tips filled - that is, the number of full battery, but the phone can not use up.

According to my understanding of lithium batteries, lithium batteries are generally self-protective function, rarely charge-discharge excessive, but now, this phenomenon seems to have been completed - After much deliberation, I would be placed inside the conductor of the telephone line is there are ways to activate the battery. So the Big Nine in, plug-load line. “Black!” Big Nine automatically stopped and refused to load. Moment of a phantom heart sighs. Fortunately, there is no fee to take a nine short years. (actually the real reason is that nine small phone messages are a lot of great nine are currently facing me as a game), so the evening because it was really late, and stir for a long period without Gao Ding, and is I dare not use that piece of the fast charge to charge a dead battery again.

This morning, a ghost continues to take this piece of rechargeable VGP-BPS10 batteries overmix.

Website for a moment of excessive discharge of lithium batteries to the approach here, but the method does not overload. Indeed, aware of Lithium battery life is very long, but in the excessive discharge through normal use after return to active status after a few, so I think for a moment, since the excessive discharge may be restored, why not over-charging?

Note that the piece of board, regardless of who I spend a couple of times have been maintained at about 3% of electricity (the Big 9 members) must know that the great new, all came to a consumption of small power of nine large, so they are very frequent switching machine If a number of electricity will be consumed, so the 3% of electricity is consumed, it shows that the Dell Inspiron 1300 battery still has power. So, simply put a piece of ghost cells appearing on the Big Nine inside, play with the big 9.

Size of the nine power plays, essentially playing the game, then one day be able to put solar panels are consumed, for a ghost is seen with the use of electricity can be the means crazy for this piece of overcharging return to normal power supply (according to my knowledge in physics, this approach should be feasible). The whole process took about five hours, a ghost has ever been stuck in the game page, if not playing games, there is no exit. During boot, at the prompt once the power is low, see charge of 3%. 13:00, when you are prompted more than once power is low, see the power of 2%. After electricity was View all 2%. Over three hours of the afternoon when the power has created a low-power, or about 2%.

A ghost does not shut down, remove the battery directly. And then re-load, turn, reassuring the phenomenon, and the battery icon prompts full frame, view the power consumption is probably about 91%. Preliminary estimates slightly, depending upon the extent that I played the game, usually consumed at least 10 ~ 15% of electricity, which is, I finally managed to get my panels back to normal.

Xie is really a feeling of days. Therefore, the lithium is still very valuable, and be careful love.

By the way saw a long interview of the lithium battery term means: If you do not use lithium batteries for long term storage, the best discharge to 50%, and probably can be stored for one year. Up to one year, first ~ to ensure that the battery charge and discharge function was normal.

Basic Lithium Battery Knowledge

Battery and notes

(1) If the new battery should be a continuous load of 12 hours.

(2) Fully charge and discharge. Cycle three times to awaken a new Laptop battery.

(3) long when using external power. A suggested removing the battery, so as not to affect battery life.

(4) Periodic charge-discharge time away [1 months or more] does not have a computer or found that the battery charge and discharge time shorter, should be made after charging the battery fully discharged usually at least a month, a full-time discharge.

(5) Is preferable to turn off the computer while charging, disconnect the power load in half-way.

(6) To avoid the impact of man, demolition, falls, heat or short-circuit

Lithium-ion battery-related knowledge:

1, lithium-ion battery

Lithium-ion batteries currently liquid lithium-ion battery (LIB) and lithium-ion polymer battery (PLB) categories. Among them, the liquid lithium-ion IBM ThinkPad R50 battery is the Li + intercalation compound as the secondary battery positive and negative. LiCoO2 cathode using lithium compounds LiMn2O4 or the negative of battery - intercalation compounds of carbon. Lithium-ion batteries due to high voltage, small size, light weight, high energy, no memory effect, no pollution, low self-discharge cycle life long and are ideal for energy 21st century.

2, Li-historic ion battery development

Lithium and lithium-ion batteries in the 20th century developed a new battery of high energy. This battery is a lithium metal anode, the cathode with MnO2, SOCl2 (CFX) n and so on. 70 years in practical use. Because of its high energy, battery voltage high operating temperature, long shelf life, etc., has been widely used in military aircraft and civilian small, such as mobile phones, laptops, camcorders, cameras and so on, partly to replace the traditional batteries.

3, Li-Development Prospects of ion battery

Lithium-ion VGP-BPS9 batteries for its unique advantages in performance portable devices such as laptops, cameras, mobile communications are universally applied. At present the development of high capacity lithium-ion batteries in electric vehicle to begin a trial, which should become the 21st century, the power of electric vehicles, one of the engines of change, and a satellite, Aerospace and storage aspects of the energy applied.

4, basic performance of the battery

(1) The battery open circuit voltage

(2) The resistance of the internal battery

(3) The battery voltage

(4) The charging voltage

The charging voltage is the secondary battery charging, the external power added to the battery voltage at both ends.

The basic method of pricing Youheng load current and constant voltage. Usually use the constant current load, the characteristics of the process of charging the load current constant. Whether charging progresses, the active substance has been restored, the reaction zone at the electrode is reduced, the electric polarization has steadily increased.

(5) Battery capacity

Battery capacity refers to the amount of electricity from the battery to get, often C, said unit, said common Ah or mAh. The electrical properties of the Dell Inspiron 1150 battery capacity are an important indicator. The battery capacity is usually divided into theoretical capacity, practical ability and capacity.

The capacity of the battery capacity of the decision by the electrodes if the electrode capacity varies depending on the capacity of the battery capacity that small electrodes, but in no case the sum of positive and negative capabilities.

(6), the battery performance and storage life

One of the main characteristics of sources of chemical energy is used to release electrical energy can be stored when not in power. The so-called secondary battery for storage performance is to maintain the ability to recharge your batteries.

For the secondary battery to measure battery performance good or bad, when life is an important parameter. Following a battery and secondary discharge is called a cycle (or have been in this cycle). At a certain load and discharge system, the battery capacity reaches a limit value is fixed before the battery can withstand the charge and discharge once known as the life cycle of secondary batteries. Lithium-ion batteries have excellent storage performance and long life cycle.
