Phone battery charging in the right ways

We know that cell phones are a source of electrical energy, which is the driving force for cell phones, there is no battery power supply, cell phone is a piece of scrap iron, a high-capacity high-performance batteries, not only to the phone’s range for a long time, but also to protect The phone circuit, making phone for a long time to work efficiently, while likely to cause unexpected damage to the emergence of mobile phones. And our players, the laptop battery performance in the factory, had been determined, the size of its power, performance, good or bad, are determined by the battery itself, in this regard we can not change the man-made, but That does not mean that we get the battery after it is not so. Cell phones are used by the lithium-ion rechargeable batteries, used in the run out of storage capacity, the need to be supplementary power re-charging. You do not look down on the link in charge, a good battery charger and charge the correct way to maintain a long battery standby time, but also to extend battery life. Step further said that mobile phones can also play a role in protection. On how to approach the charge, often in the forum, players will be asked, after a period of time to actually own and use for reference, I summed up the following points:

1. Lithium battery factory in general, manufacturers activated to deal with, and pre-charging, the batteries have more than electricity, to buy a new cell phone battery is a lithium-ion, then the first 3 to 5 times as the adjustment period recharged, should be sufficient for more than 14 hours To ensure that the full activation of the lithium-ion activity. Lithium-ion ibm battery memory effect did not, but there is a strong inert, should be fully activated in order to guarantee the future be able to use to achieve the best performance. The first charge on this issue, I also consulted with Samsung’s technical staff has given me the answer is that Samsung’s original battery in the factory had already done a full activation of the deal, then do not have to charge long way to activate Lithium-ion activity, for the first time as long as the battery charge, while the electricity can be filled after use. I would like to Samsung’s technical staff should be able to claim convincing.

2. Some automated intelligent rapid charger when the lights change direction, the fact that only 90 percent full. Charger will automatically slow to change with full battery charge will be. Do not immediately put the charger to cut off power, even the best batteries to power up for some time, and then use the battery is full, or else they will reduce the use of the time.

3. Charging, lithium batteries do not need to discharge, can not discharge, the current production of lithium battery charger is not discharge the function, if you adjust the speed of charge, we charge the proposed slow Chongchong Dian time as far as possible in order to reduce the fast charge Way; whether slow or fast and sufficient time should not charge more than 24 hours. If the ThinkPad T40 battery is likely to be a long time because of the enormous power of the electronic flow and burn batteries.

4. There are a lot of users to charge a mobile phone when driving, in charge of the process, a cell phone because of the use of discharge from outside, because the battery charger and power supply inside, is likely to lead to disorder voltage of the cell phone circuit boards Heat will, if the calls would have to return the current moment, the phone’s internal parts damage.

5. The battery life determined by the number of repeated charge-discharge lithium battery charge and discharge in a row could be about 500 or so, after the battery’s performance will be greatly reduced, should be avoided as far as possible within the remaining battery power and then charge the full release End, or charge with the increase in the number of , Battery performance will gradually weaken, the battery standby time is hard not to have dropped.

6. Do not expose the battery at a high temperature or cold, like a dog day weather, cell phones should not be placed under the sun, stood in the scorching sun exposure; or get air-conditioned rooms, air-conditioning on the direct blow. When the charge, the current product back to the battery a little fever is normal.

7. If the cell phone not to place too long, to the best cell phone 92P1102 to the maintenance department to apply for activation of a deal, their could be a constant voltage direct current, voltage adjustment for the 5 ~ 6V, current 500 ~ 600mA reverse battery connector . Note that the liberalization of touch, up to be repeated three times, after such treatment, re-use original charger “adjustment” charge.

8. The charge is not a good time longer, not for the protection of the circuit full battery charge should be stopped immediately, otherwise they will affect the performance of heat or overheating. Theoretical calculation of battery charging time of the method are as follows: The battery charger power divided by the output current can, for example: a battery 800MAH for electricity, for example, the charger output current 500MA for less time on the same charge 800MAH/500MA = 1.6 hours, of course, this is only theory is full of power time, when the Chargers showed that after the completion of the charge, but also the best 92P1101 for about half an hour or so up the power of time. Lithium-ion battery charger must be selected precincts, or may fail to saturation, the impact on its performance.

 

Silicon thin film battery supply crisis led to investment

Since the amorphous silicon thin film was developed, as the laptop battery conversion efficiency is only half of the polysilicon has not been universal. In recent years increasingly favor the photovoltaic industry, triggered a crisis in the supply of silicon materials. Silicon raw material prices, making cell membrane surface again. In 2007, the world’s thin film solar cell output to reach 400MW, over 181MW of 2006 increased 120% market share in 2006 from 8.2% to 12%.

Accordingly, the following components of solar heat, heat polycrystalline silicon, thin film photovoltaic cells and become a new investment hot spot in the field. In June 2008 the German Photovoltaic Exhibition, 2008 with an annual output of Taiwan can only 30MW of green energy, to be signed orders amounted to 200MW, is an annual output of 2008 to 6 times; Yutong energy production yet, have also made orders 60MW. Tianwei change security plans to invest 3.2 billion for the amorphous silicon thin film solar cell projects; Zevi announced in Nanchang, Jiangxi building the world’s most technologically advanced and largest thin film solar cell projects; in July 2008, Johnson & Johnson non-25MW photovoltaic Crystalline silicon thin film solar cell production line officially put into operation Sony battery ; Jiangxi be able to announce the formation of joint stock companies, the goal of building capacity for 50MW of amorphous silicon thin film photovoltaic cell production line. Suntech added, Vosges stake in the new extension to that variety, such as shares of the company have also announced to enter the field of thin film batteries, resulting in the domestic film pa3384u-1brs battery investment.

 

Desai shares subject to the battery so popular these days this week, up 36%

A three-day falling stocks, but failed to restrain enthusiasm for hot money speculation. satellite a75 battery Can be the first week of Niugu Desai battery today after a substantial re-try for a maximum of 4% or super, reported 6.05 yuan.

As of 10:50 pm or so, battery Desai reported 5.85 yuan, up 1.56 percent, latitude d820 battery the exchange rate reached 14.86 percent, trading volume has been close to yesterday’s closing level throughout the day.

According to statistics, battery Desai’s share price rose this week has reached 36%, the first well-deserved Niugu.

The sources said the speculation pcga-bp2nx Desai battery in addition to the ranks of hot money, and even some bodies. Analysts believe that the current stock build-up has a lot of risk, investors should not push up the funds to the ship.

 

Motherboard battery failure

Motherboard battery failure

The laptop battery is dead motherboard cause of computer failure can not be started, see dell battery.

A telephone rings, I awakened from a dream that a friend’s computer problem: press the power button, the computer and nothing happens repeatedly press the power switch is still invalid. After my initial analysis, is likely to be part of the problem of power is not enough power (power of low-grade “patent”) is a short-circuit switch, Collect a variety of tools for a pretty good idea after a friend went straight home.

Indeed, such as friends above, no matter how pressing the power switch (socket and verify that there is good access to electricity), the computer just like wood, like the “one drop of a hat.” Computer does not have any alarm sound, the motherboard does not seem to load the required voltage, power supply fan is not moving, it appears that the computer simply will not be able to power up. Open the chassis closer look at the motherboard and power supply connections and there is nothing abnormal, the power switch is also not short-circuit signs readily connect to other parts again still boot failure.

As the power of “suspects” the greatest, I have decided to replace the method used to verify, just-on-hand to have a 250W power supply, installed after the computer is still “silent”; Is this 250W power supply is Li dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery? At this time I noted the chassis installed in the four IDE devices: two hard drives and two CD-ROM. Friends said that just to upgrade, it appears that is likely to be caused by excessive power supply, two of which I immediately unplug the power plug of equipment, try to boot, the computer has not the slightest reaction.

While I am prepared to give up when suddenly the computer’s power supply fan spinning up, then heard the sound of the hard drive self-test, the display is also slowly changing light, the computer launched! But soon, start interrupting, showing “CMOS Load Failure”, and prompted by the “F2″ key to start, according to “Del” to enter the BIOS settings, no matter, I press the F2 key to enable the system to continue to guide, but in any case can not enter the Windows XP desktop, had to restart. The press “Del” key to enter the BIOS settings, friends trying to enter a password, but directly to the, and found the time to view positioned at 0:00 on January 1, 1999, and it is clear the CMOS gd761, td347, dell inspiron 6400 battery is dead . Immediately bought a new battery into one, and all equipment connected to the boot again, the smooth startup of the computer, but still showed “CMOS Load Failure”, had no choice but to enter the BIOS settings to choose “Load BIOS SAFE DEFAULTS” and restart the smooth into the Windows XP desktop, and all the restoration unabated. In the thought that the problem has been resolved, the friends suddenly find missing floppy drive icon, the system did not identify the floppy! Is just now beginning to think that the song might touch the floppy drive connection, so no choice but to open the case more thin, but still can not see the boot floppy. Calm down, just recall the operation “Load BIOS SAFE DEFAULTS”, the floppy drive is set to the default “None”, and restart to enter the BIOS settings, was to prove my idea to come back immediately, with a floppy drive while .

Recalling the whole process, everything is small CMOS battery to blame, it seems that analysis can not be in accordance with the experience of walking, but should be adaptable, to deal with the specific environment; as to why no power CMOS, the computer can start suddenly, Although my analysis may be connected to power after the computer does not start, but the power supply has power to the motherboard, the motherboard CMOS battery to be sufficient dell inspiron e1505 battery, dell inspiron 6400 battery power to start the computer, they have taken place in front of the scene.
