How correctliy to use a Lithium Dell laptop battery

2009-07-31T21:04:00.000-07:00

Battery and charger type does not match: If purchased lithium batteries, using a rechargeable Ni-MH battery charger, lithium batteries or Ni-MH battery charger to recharge. Lithium-ion batteries and nickel-metal hydride rechargeable batteries do not require the same manner, (lithium battery charging method as follows: first a constant current charging to Li-ion Dell latitude d600 series Laptop Battery protection voltage limit must be converted to constant voltage charging mode; Ni-MH rechargeable batteries for constant-current charge) This requires that the charger must have a corresponding set of rechargeable conversion, if nickel-hydrogen batteries for lithium battery, lithium battery when the voltage reaches the limit, continue to constant current charging the internal lithium battery voltage protection will automatically cut off power supply to avoid sharp internal batteries to explode, etc., lead to electrochemical reaction occurs, it occurs is not sufficient or even necessary and sufficient power is not enough electricity into the situation; if the dedicated lithium battery charger for Ni-MH rechargeable battery, lithium battery charger as a result of the constant current into a constant voltage charging Ni-MH battery can not complete the activation within the material will eventually lead the system is not sufficient enough phenomenon.

It seems the two can not be both, but there are a way to solve this problem: the charger has a switch, switch on the Ni-MH / Ni-Cd and lithium between electricity. When the switch in the Ni-MH / Ni-Cd, the charger in the MCU will determine the status of the battery is full after the automatic cut-off or trickle charge into the state; when the switch in the mode of lithium, the charger was shielding the MCU to not to misuse power lithium disaffection, which is not sufficient enough to avoid the situation. However, this charger can only charge with the protection of the lithium plates electricity, it can take to protect the safety of lithium-board power for charging. This charger is relatively specialized in terms of structure than the protection of non-rechargeable lithium electric circuit board complexity, it is a lower cost for the realization of the security functions of rechargeable lithium power. At the same time, we also advocate for the protection of users with the lithium plate, the electric discharge lithium safer. In addition, the use of this lithium Dell INSPIRON 9400 Battery charger, it will not cause a waste of inputs. Because without the protection of on board lithium battery charger designed to charge the complex, in fact, these features can protect the plate from an alternative, and the role of the protection plate can be reflected in the charge not only respect, but also when used in the discharge play a great protection.

Non-rechargeable Dell inspiron 6000 Laptop Battery into the power, often battery and charger as well as the current output power terminal blocks or bad there is no internal battery charger AC DC (ACDC) current converter circuit does not lead to charge into the electricity, many low-grade and inferior charger to recharge the battery often prevent similar incidents from happening.

How to extend Laptop Battery life

2009-07-17T20:34:00.000-07:00

Notebooks now use more and more people, as one of the main components of the notebook lithium battery problems also increased. So how should make good use of the notebook lithium batteries do? Grasp the main points:

1. Chong appropriate discharge current.

2. Minimize the discharge less than the charge or over discharge.

Although the battery is a consumable, lithium-ion battery is no exception. But no one wants to use the sperm cell of the spirit of God to the age you do not snap on the end, no one wants to own the very beginning, half dead battery does not pull the living, has been rubbing on this in 2023, people make good experience about how the chicken thing, you said it is not?

Well, Closer to home, following the battery began to speak. To explain lithium-ion battery(Fujitsu Lifebook T4010 battery ) is limited.

Appropriate charge and discharge current

General literature and the state on the standard lithium-ion battery that the lithium-ion battery charge current should be between 0.2C to 1C. This is expressed by the battery charge current capacity, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, in other words the charge current should be between 0.8 to 4A. In general, the charge current in the extent permitted by the smaller the better, rechargeable lithium-ion battery should be the beginning of constant-current charge, in my IBM R31, this current is about 2.8A, which is equivalent to 0.7C, is charging its own circuit control and can not be set. Although such a charge indicator does not exceed the standards, but it does more, especially when the battery capacity decline for some time, the charge current may be more than 1C. The length of time charge notebook now also become targets regardless of the user, the Fujitsu Lifebook T4020 battery manufacturers were forced to charge current set so high.

So the first step is to reduce the charge current. I have friends working in the laboratory, a variety of devices ranging in his trial a bit there. Power output at the series resistance try a result, current is reduced, but became intermittent charge, this is not a good thing. After trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is very stable. This is only the power flows through the machine interface of the current, the battery's charge current is estimated to bigger, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. In addition with the increase in battery voltage, charge current will be reduced, but decreased only slightly less than 0.05A. In this charge state, charging circuit seems to does not work, the battery indicator light is not bright. Such as the battery voltage up to 12.6V, the charging circuits came into play, the battery trickle charge to enter the state, this time does not matter whether the series resistance has been, the charge current is controlled by the charging circuit, and the last full charge after the end of the circuit automatically charge. The entire charge time is about 5.5 hours, if not resistance, charging time is about 3.5 hours.

Fujitsu FPCBP80 Battery is very precious, good charge control circuit is necessary. This charging method, can reduce the charge current to extend battery life, use of books at the same time, the charging circuit to control the original charge, is also relatively simple to achieve, just buy a power plug (from the power supply into books kind, it is best to buy two, the latter also referred to a method, it is necessary to good quality) and a resistor can be, and pay attention to resistance, to a large point size, after all, there are about 2W of power Otherwise, it would be more heat resistance, the best use of their constant resistance of a wire, the wire resistance and temperature resistance of the basic irrelevant. But the shortcomings of this approach is also clear is that, while not in charge of work with books. In addition there will be time to charge 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, since the beginning of charging before going to bed at night, wake up the next day on a good charge, of course, if you are a night owl or a special short sleep time, it is a different matter.

Solve the problem of small current charge, and now turn to the issue of discharge. In fact, this is difficult, after all, the book is designed to work with the discharge current will vary depending on the work of the state, the method mentioned here is limited battery capacity dedicated to the restoration operation.

Start the machine, set the power management never goes into sleep mode (standby) and hibernation (hibernate), the other are the most power-saving mode is set, including the CPU speed, hard drive shut down, close the display, and management process in the TP some do not turn off the hardware, such as sound cards, etc., and then open the battery status display window, to run in the foreground! ! ! Close other programs, in particular, screen saver and other programs that run from time to time! ! Do not use the machine, do not close the lid, let the battery discharge finished (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down, the discharge current is about 0.5A, this is my IBM R31 can be achieved at the minimum discharge current, battery discharge to the lowest setting after the machine will automatically shut down. Continued to discharge the entire time about more than four hours, according to your battery capacity may be different, this time to sleep is also a way to use the pass.

Well, the last to emphasize that this method is not dead, especially the discharge, there are a dozen times to do it, otherwise the battery still doing? Charging the best use of small current charge, of course, if an urgent need to use batteries, power supply plug inserted directly in the book on it.

I use this method of Fujitsu FPCBP95 Battery, and now put a charge 14 times the capacity has remained at more than 45, and battery design capacity is 43.2, which also decreased the time, but after filling the first released restored.

The saying goes: When effort brings success, add up! We can not be the details of the error, in life, in the use of notebook computer is! It is perhaps well-intentioned you inadvertently move, and ultimately lead to the serious consequences of inestimable! Lost a long time to develop the scientific research or small, if the loss of a beloved book, that may be worth it! What? Say that I am exaggerating? It together with me to see the details below a few errors, you share a few?

how to correctly use Apple Powerbook G4 battery

2009-07-13T18:32:00.000-07:00

Got a new battery, many users of the approach is in accordance with the business prompted the use of lithium batteries in the first three or more 12-hour charge. In this line there are a lot of controversies, in fact, this is for the majority of laptop battery is not necessary. Why? Businesses that do so in order to fully activate the cell activity, a new battery fully wake up.

For this reason it sounds very full and credible, but we have not thought about this issue. If, notebook battery manufacturers have not yet been activated on the play, such products can be said that only a semi-finished products. Can not require each user to activate cells to master skills, and can not in reality. As a result, the factory battery manufacturers have been fully activated. How are users 12-hour rechargeable Apple PowerBook G3 Battery life in favor of it?

I give a negative answer, the current laptop battery power management has a sound management system and charging circuit, when the battery reached saturation, the control circuit automatically switches to short-circuit state, so just after the time is a waste of time only. How can this activity to activate the battery? In fact, the vendor for the battery to activate the overload protection in case there is no battery charge and discharge time. Therefore, the first three 12-hour charge is unnecessary.

In the second, many users use the battery very confused, what should not have to wait until the batteries run out completely before recharging. In fact, this question should be answered is that if you can This is certainly a good thing, but the premise is that you too troublesome. Of course, I am talking about here is not referring to the excessive discharge, Practice has proved that excessive battery discharge is harmful, it will shorten the battery life. When the notebook prompts therefore low power consumption can be a timely charge. Some business has repeatedly stated that its lithium-ion battery without memory effect, this practice is extremely irresponsible. So when your battery power when there are more, or not to charge for the good, because the memory effect does exist.

Third, do not have the Apple PowerBook G4 Battery for a long time how to do so, it is recommended 40-50% of electricity into, placed in the shade at low temperature, the following parameters can explain the problem.

Storage temperature of 40% state of charge 100% state of charge

(0 degrees 98% (a year later) 94% (a year later)

25 degrees 96% (a year later) 80% (a year later)

[40 degrees 85% (a year later) 65% (a year later)

60 degrees 75% (a year later) 60% (3 months)

(Percentage of saturation at the time the relative percentage of the initial value),

Of course, the best month to come up with to use a battery, the Apple A1189 battery can ensure a good state of preservation, but also does not allow the loss of electricity damage to the battery completely.

Fourth, the use of notebook computers in the notes to the "use of one month after the release should be a full-charge" approach is necessary. Li-ion laptop batteries are generally with the management of chip and charge control chips. Management chip which has a series of registers, there is capacity, temperature, ID, state-of-charge, discharge frequency values. These values are in use will gradually change.

I personally believe that the use of notebook computers in the description of "the use of one month after the full charge should take a" major role in the practice should be amended is inappropriate in these register values, making the battery charge control and battery with a nominal capacity of the actual situation. So this kind of work or can not be omitted, after all, high-priced notebooks or aristocratic effemination.

Notebook battery purchase guide

Along with notebook's fast popularization, the notebook battery's importance is valued general consumer's more and more. The good notebook battery not can only give user's motion commerce and the digital life together brings the enormous convenience, moreover may also eliminate the unsafe factor which in the future will use. Does not want the notebook battery, besides is unable regarding the user to satisfy it to move several lives, will also bring the use the hidden danger, particularly secure question. The battery explodes together causes a notebook the destruction, will also cause a more serious consequence. Therefore the choice good notebook battery's significance is together significant. But the original installation battery renews frequently over a thousand Yuan prices, causes many users faced with the choice better performance-to-price ratio market replace product. But the second-level service market's replace product's price from 100- 800 sectors, causes the consumer to be very difficult from the price to judge its quality the quality.

The author in this paper helps everybody through the analysis notebook battery's composition and the design chooses the best notebook battery from the present market sale notebook battery's business's price and other aspect consideration.

The notebook battery is adds on the protection circuit wafer and the PVC capsule by the lithium ion 18650 electricity cores is composed, below on a analysis its cost:
1. 18650 lithium ion battery divides into 2200,2400,2600 mah three kinds, a usual notebook battery assembles (4 strings with 8 batteries 2 and). If is the original installation legal copy electricity core, usually for Japanese and South Korean or the domestic regular factory's A level 18650 electricity core, these batteries has the quality assurance, the security undergoes the strict test, its cost usual basis capacity differently in 3 dollar about, a normal notebook battery (8) cost about 24 dollars, reduced Renminbi: about 170. If after is the B level or opens machine the battery (installs, has quality question electricity core, Japan, Han has quality even safe nature question electricity core, frequently in the Chinese dumping) its cost selling price for the Renminbi between 10-15, after such electricity core assembly or anew assembles, a 8 electricity core's notebook battery's cost is 80-120 Renminbi. Moreover, and what is more, some illegal factories with worse 18650, has the security problem frequently, very easily the inferiority product assembly which explodes yours notebook, its 8 electricity core's notebook battery cost may about 50 Yuan.
2. About the PCB notebook battery's control panel, a good control panel, may lengthen the notebook battery's service life, the safeguard security, its cost usually about 80 Yuan; If is not the good function not entire PCB battery control panel, or is opens machine the board, the cost about 30 Yuan,
3. About the PVC capsule, good capsule cost in 30 Yuan, not good inferiority about 10 Yuan.

In the synthesis sues, by good has the quality guaranteed notebook battery (8) the cost should about 280 Yuan, therefore a good non-first wife notebook battery (8 electricity cores) the low selling price arrives in the terminal consumer's hand including the operation cost and the profit should about 350-550 Yuan; If is the B inferiority notebook battery (8) the cost is about 120 Yuan, its selling price may be 200-300; If is the lowest quality notebook battery (8) the cost may be about 80, its selling price usually is between 100-200.

HP Pavilion DV4000 battery can be charged

2008-12-09T05:31:00.000-08:00

Alexander·Smith: I bought HP DV4000 laptop PC 7 months ago and the battery is the original HP Pavilion DV4000 battery. After returning home from work last night, with the usual habit of opening my hp dv4000 laptop pc, what surprised me is my HP laptop PC warning me no capacity is detected. I put the HP DV 4000 Laptop on the table with the Adaptor pluged in the early morning. And where is the capacity? How that(HP dv4000 battery have no capacity) happen?! It's my battery burnt out after be charged all the night?

MY first reaction is that his HP Pavilion DV4000 battery power can't be charged after seeing that. When I told him that he need a new HP Pavilion DV4000 battery power. He say he use this battery just 8 months and it's a original HP Pavilion DV4000 laptop battery.

So he go to the HP eSupport for help, and then he took all night to download the program, set the BIOS to the default setting, clean up the battery slot ... All the ways the HP eSupport provide he did all, but the battery was among the disappeared ...and then the eSupport center told him he have to change a brand new HP Pavilion DV4000 battery! And he complained to me again that a new original battery is not so cheap and what cost can buy a nerw laptop PC in two years.

A original laptop battery is much more expensive than the replacement battery. It's battery if you can persuade the HP CO.LTD to change a new battery for you laptop. But even the original laptop battery have it's life. So If your first original laptop battery exhaust you can change a replacement one. The replacement is unnecessarily worse than the OEM battery. In fact, both of replacemnt battery and the HP OEM battery are made from li-ion HP battery cells. and the repalcement battery have much more capacity, usually it can works much longer. What is important is that it's cheap. especially for the people have many business trips, a replacement battery is a perfect choice. But replacement is not the same. The replacement battery made from A-quality cells much more battery than the recovery cells.

How to use and maintain a laptop battery

2008-11-07T19:43:00.000-08:00

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

Use a full charge cycle before recharging. All laptop batteries in our site are Li-Ion batteries, so, they do not have memory which you might find in NiCad batteries. However, each chemistry has a limited number of charge cycles, so use a full charge cycle before re-charging to maximize your battery usage. When charging your notebook laptop battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. Don’t worry, this is a normal phenomenon with rechargeable batteries. Just simply remove the battery from the laptop and repeat the charging procedure.

Try To avoid over-charging, especially, do not let your battery over discharge. When charge and use you battery, it is normal for notebook battery to become warm. But the battery exhaust much faster under the high temperature, you should avoid using your laptop battery in shady, cool place. Hit the battery, and other acts will also accelerate depletion of battery. So, pay attention to your battery as much as possible.

If you don't use you laptop battery for 1 month or longer, you can remove the battery from your notebook, remember charge leave your battery power about 40%, stored in a shade, cool, dry place away from heat and metal objects and direct sunlight, but not in the refrigerator. It’s objected strongly store your laptop battery for over three months without any using. A charged apple laptop battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.

How to choose a notebook battery

2008-11-06T20:03:00.000-08:00

If you buy a new replacement laptop battery recently, how to determine the length of battery life? At this time of the following can be relatively simple formula to do the calculation.

The capa(mAh: milliampere hours) multiplied by voltage (V: V), and then divided by 1000, could be kilowatt-hours (Watt-Hours) values.

Let's calculate: First of all, you start to read the current battery capacity and voltage of the mAh value, and then they are multiplied together and then divided by 1000, if your battery has been used for the current unit Ah, because it shows that They have been divided by the first of 1000. For example, if you use 10.8 volts and 4400mAh battery, the formula is: 10.8 x 4400 / 1000 = 47.52, or converted into 48 kilowatts / hour (W / h), the higher the value, the better. Battery capacity is usually high or low battery pack is the size of the figure, the more the battery cell, said a few more capacity.

Why should I need a replacement battery?
