Replacement Battery

The new battery in use after a period of time will be “aging”.
Specific expression of the resistance, when both ends of the charging voltage rises faster, so it is easy to be charging control circuit is judged to have full capacity of nature is “down”. The relatively large battery internal resistance, discharge voltage drop, the speed, the system is easily mistaken for a voltage is not enough, the lack of electricity (in fact, there is no electrical discharge). As can be seen from the above description of the process of aging of the LG Laptop Batteryis a vicious circle, found faster battery working time off when they should exercise it, otherwise, sooner or later scrapped.

In addition, many lithium battery failure battery bag failures have led to a power-saving core, this phenomenon can not be avoided: used for a long time because the Asus g73jh battery every power-saving nature of the core can not be completely consistent, there is some quality to the less fortunate first aging, the destruction of the whole (series after) the discharge curve. And simple say is that section of bad batteries before charging full discharge but first had finished, and this time the capacity of the batteries are not being fully utilized. A power-saving core overcharge / over-discharge monitoring circuit that will not make the LG lu20-56na battery is full / discharged. Such as charging other batteries close to full charge pressure when that section of bad batteries may have reached 4.30V even higher terminal voltage, resulting in overcharge damage, while the other was sufficient dissatisfaction.

Battery charge and discharge

The first constant current lithium-ion LG r410 battery charging, fast charging, the voltage reaches a certain value and then to constant voltage trickle charging. Laptops usually are not strictly constant-current charge monitoring device. Large load on the system when the charging current is small, whereas the large, the current from the AC power adapter power margin. Obviously, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources. I tried to run side Superπ, while charging the way, found that the charge current varies between 0.70 ~ 1.70A, can not meet the requirements of the charging of the LG lu-20 battery, so I worry about this kind of work, rechargeable batteries has been damaged. Do not operate the IBM statement on the request of the laptop charging is probably the reason.

When you start charging, if we can select the charge mode, do not select the fast charge mode (Express charge mode) to avoid premature battery “full”. There is Asus a32-f82 battery power is low, the highest performance, prohibiting the use of the CPU in order to reduce competition for power. Laptop CPU supports SpeedStep technology, it is best to install the drivers (responsible vendors will be installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flag, right-click on it to performance tuning options. Windows XP system, SpeedStep program will be problems, this time to rely on to adjust the program to modify the BIOS parameters or some brand dedicated software tools such as IBM laptop is very powerful.

On the the lithium discharge or always-on, let the natural discharge better. It is best not to use physical methods (string resistors and the like). Not to say that this is not the only risk is relatively large, the internal protection circuit did not work, asus laptop battery void the worst possible battery explosion, of course, this is unlikely. Circuit hidden danger is not possible, some of the big manufacturers have discovered the potential risk factors in the design and recycled through battery As for the mobile phone battery explosion is not heard.

Little knowledge

Generally the laptop battery protection circuit parts are usually regulator block, control chip, insurance, and temperature probe. Temperature protection is usually a one-time internal fuse (some 130 ℃ fuse), used to monitor the voltage regulator block work. If the charging and discharging process, and immediately there will be a current temperature protection, the fuse blows, Sony Laptop batteries inside the circuit for the off state, and unrecoverable. If you want to fix the only replacement temperature protection, but these shall only be such as temperature protection is difficult to find in the market.

Discharge is to try small current discharge, operation and let the CPU spin down hard stall, screen tone is dark (or close off), and then do not run any programs until the laptop automatically shut down. The emphasis on low current discharge is to prevent the laptop premature detect the Sony VGP-BPS20 Battery voltage is low.

The easiest way

1, turn off the automatic standby function of 3%
2, change the power management project, 10 minutes 10 minutes automatically turn off the monitor automatically turns off the hard drive has not standby

3, wait for the system in this state automatically shut down

Doing three general data measurement can be corrected

Laptop use can not be separated from the power transformer, power transformer knowledge but also understands how much? The notebook voltage problems, how to judge? ! Below, Asus EXA0904YH Charger is a matter of common sense speak one by one: First, the nominal voltage and current of the power adapter (hereinafter referred to as the power supply) What does it mean? First, the nominal voltage of the general power supply, refers to the open circuit output voltage, that is, the outside is not connected to any load, and no voltage when the current output, so it can be understood as the upper limit of the power supply output voltage, this voltage. The case of the active regulator element used for the internal Asus A6Jc Ac Adapter, even if the mains voltage fluctuate, and its output is also a constant value, as the market in general small transformers, such as the class with the Walkman power, if the mains fluctuations The output of the power supply will fluctuate. Not necessarily real-load voltage of the common power supply adapter and the nominal voltage is completely consistent, because of the characteristics of electronic components can not be completely consistent, error is smaller, the higher the consistency requirements of the electronic components, the production cost is high , the price will be more expensive. Any power have some internal resistance, so when the Toshiba PA3715U-1ACA Ac Adapter output current when the internally generated voltage drop, resulting in two things, one is to produce heat, so the power will be hot, and the other lead to the output voltage decreases, the equivalent of internal consumption. Second, are of the same nominal voltage power supply, the output current can be used in the same laptop? Supply voltage, output current, and can be used in the same books. The basic principle is that the nominal current of the power supply can replace a small nominal current power. Estimated that someone would think that large nominal current of the power will burn books, because the current big thing. In fact the current much depending on the load in the case of the same voltage. When the notebook high load operation, current books go into standby when the notebook current on small and large nominal current of the power supply has sufficient current margin. Instead, it was replaced with 56w power supply 72w with them no problem, because usually Asus ADP-150NB D Ac Adapter designed to leave a margin, load power must be less than Toshiba PA3714U-1ACA Ac Adapter, so this place in general use feasible power power margin, but the remaining few Once your books picked up a lot of peripherals, such as two USB hard drives, and then the CPU running at full speed, and then there is a base above to drive at full speed to read the disk, and then coupled to charge the battery at the same time, estimated on the dangerous, to feel your power supply is not already boiled eggs out by hand at any time. Best not to use a small current power supply instead of the high-current power supply. Identical machines, the temperature of someone else’s power, I am always very hot, and why? First, check your notebook run, is not like the above said two USB hard CPU running at full speed, hard disk read and write crazy, drive at full speed to read the disk, while charging the battery, placed music loud, screen brightness, wireless network card has been detection signal, and so on, make good use of power management, according to the status of the task reasonable adjustments books work is very important. Power nominal voltage is higher than my laptop battery voltage a lot will not be an accident, right? First of all, you know, the power to the notebook powered with battery to supply of books is different. Battery-powered, Samsung n150 battery output is a pure DC voltage of the battery is neither possible nor necessary to design very high, only about 3.6V, so many batteries are lithium chemical characteristic determines a saving core output voltage is the three series, 10.8V will become a very popular battery voltage. The nominal value of some cells than 3.6V integer multiple of slightly larger, such as 3.7V or 11.2V, etc., in order to protect the battery. Supply, the situation is more complex, you first need to filter added further voltage regulator to ensure stable operation of the power performance is not very good case, the voltage regulator is divided into two parts: a notebook Toshiba PA3469E-1AC3 Ac Adapter , to charge the battery. To that part of the books powered with a battery-powered, the same, and that part of the need to charge the battery only by the charging of the battery control circuit can be added to the batteries, the control circuit can be very complicated, so the power supply voltage must be greater than the electrical The core voltage have a sufficient capacity to supply to the charging control circuit of each unit. Real voltage applied to HP probook 4530s battery will never be the nominal voltage of the power. In addition, we look at the battery charge control circuit including what should be the primary regulator, precision tunable regulator SCR adjustable pulsating output, regulated output current feedback, chip charging process of recording and computing, the charging process self-feedback regulation parameters, and so on, these can consume energy

Your new laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.

When charging the laptop battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.

It is important to condition (fully discharge and then fully charge) the laptop battery every two to three weeks. Failure to do so may significantly shorten the battery’s life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user’s manual.

How to Charge a Laptop Battery for the First Time]

Insert the battery into the hp laptop battery slot of your laptop if it didn’t come with the battery already inserted. This slot is typically located on the underside or back of your laptop.

2.Plug your laptop into a power source and allow the battery to charge to 100%. Most laptop batteries come discharged, or empty, and should be fully charged before use. Sometimes the battery indicator will show 100% after only a few minutes. If this happens, turn your computer off, remove the battery and attempt to charge the battery again.

3.Discharge the replacement battery for dell laptop fully. Simply turn your computer on and disconnect the power source. Don’t turn it off until the battery is completely discharged. Allow the laptop to shut down by itself.

4.Recharge your battery fully again. After the battery is fully charged, it has been calibrated once.

5.Repeat the calibration process two or three more times. Your laptop battery is now charged correctly.

Myth: laptop battery without power all run out before charging
Notebook batteries are lithium batteries, lithium batteries, run out of Dell Inspiron 1564 Battery again for a long time is full simply do not have any effect, or even harmful. Because lithium battery does not exist in the so-called “buffer effect”, only the early nickel batteries have this feature. Laptop battery life is generally only with man-made damage or natural life. Basically, the battery life is fixed ,300-600 charge and discharge times, and generally available for 2 years.
Myth: When the power is connected, Dell Studio 1749 Battery can pull or not to pull
Stubbs and do not pull out depending on the actual use: do not disconnect the battery while connected to a DC power supply battery and no harm, because the fully charged battery will no longer accept any power injection, power will all turn directly to the laptop supply system. But when the laptop high-speed operation, the internal overheating is best to remove the battery, otherwise it is harmful.
Proper to charge the laptop battery
Should try to avoid light depleted rechargeable battery power, because this will give the Dell Studio P02E Battery a lot of pressure to cause damage. More feasible approach is to be charged when the remaining 20-30% of electricity. Laptop lithium battery in fact the number of light / charge “is limited, all used to recharge only greatly shorten battery life. The same time, the battery should be charged in a dry place, Also note that the heat problem, which is the enemy of batteries.
Tip: the use of mobile phone batteries, laptop batteryis not the same, may be a lot of people will be based on their own experience in the use of the mobile phone battery to determine the feel that the laptop battery should recharge all used this idea is wrong.

How to save laptop battery has not been used for a long
The laptop battery is fully charged, should put photoelectric save or save? Long-term preservation would put photoelectric batteries will lose their activity, and even lead to the control circuit protection self-locking and can not re-use, fully charged the long-term preservation will bring safety hazards, the ideal method of preservation is to use electricity to about 40% and then stored in the a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take Asus A32-F80 Battery out to use, both to guarantee battery good state of preservation, but not so the loss of damage to the battery runs completely.
Several measures to prolong laptop battery working time
1> lower the screen brightness: fn + down / up key combination to quickly adjust brightness (specific fn + which keys need to see each notebook).
2> make good use of standby, sleep and other functions: when a longer period of time without a computer, allowing notebook standby or hibernation, saving power and extend the life of the computer.
> Open cpu speedstep feature can greatly extend HP ProBook 4730s Battery operating time: cpu speedstep function in bios default startup when using the battery, cpu will automatically down-use to save energy. Not open, press F2 to enter BIOS found in Performance, set Speedstep Enable Enabled bootable.
4> use HP ProBook 4530s Battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals at the same time and avoid enable large 3D programs, games, etc., in order to reduce unnecessary battery consumption.
