Replacement Battery

Laptop battery aging can not be avoided, almost all of the repair methods are trial “deep charge deep discharge” principle, in order to alleviate the Dell Latitude E6320 Laptop Battery memory effect. Undeniably, however, the depth of charge and discharge operation will not be good for the laptop battery, not a method in order to do this. If battery life is only tens of minutes, then care should be taken to this method of operation. In addition, vendors have Dell Latitude E6220 Battery optimization own depth of charge and discharge the Dell Studio 1747 Battery capacity can once again raise the argument does not exist. But exactly when the depth of charge and discharge is difficult to master, after all, are not the same each time it is used, the power consumption, it is recommended that you With BatteryMon this professional software. BatteryMon is a small software specifically for Asus Eee PC 1005HA Battery monitoring, especially for those machines without built-in power management chip and software, it will undoubtedly help a lot of great help. BatteryMon most salient feature is able to discharge curve, and the installation will run automatically. A good performance of the Dell Vostro V13 Battery will have a very regular discharge curve, as shown in the figure, basically each drop a grid about the same time. If it is found that there is a very unusual beat, then it is necessary to repair cell “deep charge deep discharge”. “Deep charge deep discharge” battery calibration is an effective method to deal with aging batteries, in general, each brand notebook will have a dedicated battery calibration software. For example, the IBM ThinkPad series dedicated discharge software, Recommended all using IBM notebook users. However, the procedure needs to be repeated three times to get the best results. Download discharge software and executed, the system will be prompted to create installation disks. Use the installation the disk boot PCDOS, prompted to unplug the asus exa0904yh adapter the discharge software will automatically discharge control. When the notebook will automatically shut down after it was over, then we can connect the AC power to charge, the time control 9 to 12 hours, repeated 2 to 3 times. Asus G73JH batteryactivation key is to find a suitable discharge software. If your laptop is unfortunately no dedicated discharge software, you can close the BIOS and power management features in Windows, then do not run any program will run out of battery charge, then turned to about 80%, tantamount to manually “deep charge deep discharge” repeated several times. In fact, the purpose of this practice is to let the battery current discharge, which discharge state in our daily use is impossible to achieve the effect of discharge and those dedicated basically the same software. Under normal circumstances do not easily use the battery, the Asus G73 Battery life, the more the shorter the life, the worse endurance! !

Laptop battery correction(2)

Laptop life become shorter because many charge and discharge process, the battery in the laptop BIOS system battery power a miscarriage of justice, this case, we can let the battery calibration method notebook power remaining to give full play . Introduce the following two methods to calibrate HP ProBook 4520s Battery.
Standard calibration method: using notebook bios Sony VGP-BPS8 Battery calibration

Many brands of notebook computers are integrated in its BIOS battery calibration procedures, the general statement in English is called “Battery Calibration” battery proofreading. Direct access to books BIOS HP-Compaq nw8240 Battery calibration operation can be done.

1, boot, after the start-up screen appears, press F2 to enter BIOS menu; through the left and right arrow keys to select the Power menu.

Enter the Power menu, you can see “Start Dell Precision M65 Battery Calibration” option, select it and press the Enter key to perform.

3, when the screen turns blue, and English prompted to plug the notebook power adapter to charge the Dell Latitude E5520 Battery. And so the battery is fully charged, the screen prompts the user to disconnect the power adapter. After the notebook continue to discharge the battery until the battery runs out.

4, this process will take some time, and then connect the power adapter to charge the battery until the battery runs out after the automatic shutdown, but do not boot. Charging is complete (charging indicator goes off), and the HP ProBook 4420s Battery calibration process is completed.

Manual correction method: let the laptop boot natural discharge

Some notebook to find how to find the battery calibration option in the BIOS. Is this Dell inspiron 8200 Battery calibration can not hold it? Manually set the books to work properly discharge until the automatic shutdown.

The principle of the natural discharge

On the surface, the battery calibration process is to charge and discharge the battery, but it is not like we imagine that activate the battery, because Toshiba PA3536U-1BRS Battery now are lithium batteries, there is no activation problems. The charge and discharge of the real purpose is to allow the computer to re-recognize the capacity of the battery. So to try to call on clean, so that books work in smaller power correction effect so we go.

, Notebook operating system (Windows XP for example) into the “Power Options”. Select the power scheme to “always open” and “Turn off monitor” and “Turn off hard disks” is set to the shortest possible time, and the system standby to be set to “never”.

2, in the “Power Options” in the “alert”, cancel all alert options, the purpose is to let the HP-Compaq nc8430 Battery is completely depleted until the shutdown.

3, after setting, close all applications, turn off the WIFI, unplug the power adapter, battery-powered. Do not do anything until the Asus c41-ux50 Battery runs out after the automatic shutdown. After discharge, even on the power adapter, the battery is full, then completed a battery calibration.

If the correction to the Dell XPS M1730 battery, the battery life is not obvious, it may be the battery itself due to aging, if the laptop battery life is normal, I do not recommend using the battery calibration.

Laptop battery maintenance

When no external power, if the working temporarily with less than a PCMCIA card slot, it is recommended to remove the card first to extend Toshiba PA3399U-2BRS Battery?

2 at room temperature (20-30 degrees) for the battery of the most suitable working temperature, the temperature is too high or too low operating environment will reduce

Dell Inspiron N5010 Battery?usage time.

3. Use of laptop computers in the environment can provide a stable power supply, remove the battery pack for extended battery life is not correct. Asus laptop fully charged battery, the Asus Eee PC 1005P Battery charging circuit will automatically shut down, so it will not overcharge.

4 is recommended that an average of three months to conduct a battery

Dell Inspiron 15R N5110 Adapter correction action.

Minimize the number of battery

Directly related to the life of the battery Toshiba PA3715E-1AC3 Adapter and discharge times, one charge, the battery forward to retirement step. Suggest that you try to use an external power supply,

Frequent use of the external HP Pavilion DV6000 Adapter when the battery is removed, in order to prevent repeated charge and discharge?

Original lithium Asus N61J Battery in the natural discharge, if there is access to power there will be the case of repeated charging and discharging, which will reduce the battery life. Notebook power control circuit design this feature will automatically charge: When the battery is less than 90% or 95%.

7 power after the exhaustion charge

Regardless of your notebook uses lithium or NiMH, try to Dell Latitude E6510 Adapter must be exhausted after the full (capacity less than 3%), which is the best way to avoid the memory effect. Lithium also have memory effect, but its memory effect smaller than nickel-metal hydride Bale.

8 the usual precautions

Usually used to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid Asus k50in Battery contact with metal objects such occurrence.

Laptop battery core

Notebook battery is divided into 4 core, 6-cell and 9-cell, 12-core, etc.. Simple, 4-cell battery life of 2 hours the 6 core compared to 3 hours, and so on. Course, the greater the number of cores, the longer the battery life, of course, the price is higher. The average home user is recommended to use 4 cores, mainly at home, have a stable power supply. General office users recommend 6 core. Higher mobile office requirements, we can consider the 9-cell and 12-cell battery.
You can use the Master Lu detect laptop battery use details, please reference: how to monitor the use of the laptop battery.

Note: see all replies everyone 3,6 point is controversial, re-edited, re-This gives us an account of. 3:00 to explain the reason we do not have to worry about overcharging in the process of laptop use. 6:00 If your battery is lower than the set, plug the

laptop ac adapter will be automatically charged. It is recommended that do not frequent the laptop battery is low when the power plug, and this time does require frequent use of an external power supply, it is best to remove the battery.

The new laptop battery is user using a laptop computer is an essential thing, when you need a mobile office or can not use an external Dell PA-21 AC Adapter situation, we need to use the laptop battery, then how can better care of their laptop battery so that it provides more long life time? Next, I will detail about HP elitebook 2560p battery maintenance tips. Now appearing on the market penetration is highest lithium ion battery (Li-ion). Know your laptop battery you need to clarify the following parameters: battery capacity, rated voltage, temperature normal use. Capacity size judgment marked mAh HP Pavilion DV7 Laptop Battery. MA when the size is directly related to the hp laptop battery use time, but it can not be generalized. Not to say that the greater use of the capacity of the laptop battery time will be longer battery life is closely related to the actual use of the process as well as the notebook’s power consumption. Normally the next higher the energy consumption of the configuration of the laptop must be the greater, the greater the amount of computing power of the run, the faster the passage. Rated voltage rated voltage is divided into HP pavilion dv4 battery and notebook rated voltage, generally both, there is a certain difference between the former refers to the longest stay during the time of the voltage laptop battery when the battery voltage drops during the discharge process. Laptop while charging use or just has been charged, the voltage will than use only the battery. Therefore, the rated voltage of the HP pavilion dv9000 battery marked slightly lower. Normal operating temperature is the the Dell latitude e6320 battery normal working temperature range, it is possible to use in the non-normal temperature hazardous (explosion), and unnecessary trouble (leakage, a sudden power failure), general battery rarely occur in the course of this kinds of situations, but in use, not the effect, to avoid the battery close to hot or cold objects.

Exactly how to distinguish between the parameters of the battery?, We can see from the above picture, the Dell latitude e6420 batterycategory for Li-ion, lithium-ion battery is. The rated output voltage of 10.8V, 4400mAh charge. Some batteries also marked the manufacturers, production, normal operating temperature (0 degrees Celsius to -60 degrees Celsius), the Dell vostro 3400 battery identification. These logos, we can view the own notebook battery specifications.

Laptop battery structure and reasonable charge and discharge

The lithium-ion battery cathode materials are usually composed of the active compounds of lithium, the negative electrode is a special molecular structure of the carbon. The main component of the common cathode material LiCoO2, charging, added to the poles of the toshiba battery potential forcing positive compounds release of lithium ions, embedded negative elements arranged in a lamellar structure of carbon. Discharge, lithium ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. The movement of the lithium ions produces a current.

Reactions lithium sony battery cathode materials are usually composed of the active compounds of lithium, the negative electrode is a special molecular structure of carbon. The main component of the common cathode material LiCoO2, charging, added to the poles of the battery for samsung potential forcing positive compounds release of lithium ions, embedded negative elements arranged in a lamellar structure of carbon. Discharge, lithium ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. The movement of the lithium ions produces a current. Should principle although very simple, in the actual industrial production, however, the need to consider the actual problem much more: a positive electrode material of additives required to maintain the activity of the repeated charge-discharge, the negative electrode material in the level of molecular structure to design in order to accommodate more lithium ions; filled in the electrolyte between the positive and negative electrodes, in addition to maintaining stability, but also needs to have a good electrical conductivity, reducing the lg laptop battery internal resistance.

Although the lithium ion battery is rarely have the memory effect of the nickel-cadmium batteries, the principles of the memory effect of the crystallization, this reaction is hardly generated in the lithium batteries for lenovo. However, the lithium-ion battery capacity after repeated charge-discharge will decline, its causes are complex and varied. Positive and negative changes, from the molecular level, the positive and negative on the capacity of the lithium-ion hole structure will gradually collapse, clogging; From the chemical point of view, is the active anode material passivation, Vice reaction stability other compounds. The physical will appear on the cathode material gradually peeling, in short, ultimately reducing the number of ibm lithium-ion batteries can freely move in the process of charging and discharging.

Over-charge and over-discharge, cause permanent damage to the gateway lithium-ion battery will be positive and negative, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ions and making it appear lamellar structure collapse over-charging lithium-ion will too hard into negative carbon structure, and makes some of the lithium-ion no longer be released. This is also why the lithium apple battery usually equipped with a control circuit causes the charging and discharging.

Not suitable temperature, will lead to other chemical reactions within the lithium-ion battery to generate compounds that we do not want to see, so many of the lithium-ion battery is between the positive and negative features the protective thermostat diaphragm or electrolyte additives. Asus laptop battery heat up to a certain case, the composite membrane film hole closed or the electrolyte degeneration, increased battery internal resistance until the circuit, the battery is no longer warming, to ensure that the temperature of the battery charging normal. Deep charge-discharge can improve the actual capacity of the lithium-ion battery? Experts clearly told me, this makes no sense. They even said, “activate”, three times a full charge and discharge before the so-called use their knowledge of Dr. figure out what is necessary. However, why a lot of people deep charge-discharge laptop battery Information marked capacity will change it? Will be mentioned later.

Laptops use lithium-ion compaq batteries are generally with management chip and charge control chips. Management chip, a series of registers, there is capacity, temperature, ID, charge status, discharge times and values. These values ??are in use will gradually change. Personally, I think that the main role should use a month later in the instructions for use of the laptop should fully charge and discharge practice is to fix these registers where improper value, making the battery charge control and a nominal capacity of the battery match actual situation. The charge control chips to control the battery charging process. The dell lithium-ion batteries charging process is divided into two phases, constant current fast charge phase (the battery indicator light yellow) and voltage current phase (the battery indicator light flashes green. Constant current fast charge phase, the battery voltage is gradually increased The standard voltage to the battery, and then transferred to the constant voltage phase control chip, the voltage will not rise to ensure that you do not over-charge current as the battery level rise gradually weakened to 0, and the final charge.

Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery power, this is that we read in the Battery Information wh. Values. The lithium-ion battery in repeated use, the discharge curve will change, if the chip has been no opportunity to once again read out a complete discharge curve, the calculated electricity that is not accurate. Therefore, we need deep charge and discharge to calibrate the acer battery chip.

Finally, my view is that the maintenance of the battery.

Why the laptop battery will explode?

Compared with other secondary battery technology, lithium-ion battery is lighter, cheaper, and higher energy density. It has become now the main form of rechargeable batteries, from cell phones, laptops to cars and various items of business jets in the use of lithium-ion batteries. This acer battery has a small problem – they are not only short-circuit, also caught fire and exploded. Consider the following Gizmodo website introduction:

The lithium-ion battery for toshiba is the reason why there will be an explosion tendency, is called a “thermal runaway” process (thermal runaway) to blame. In essence, “thermal runaway” is an energy positive feedback loop process: the elevated temperature will result in the system heats, the system heats at elevated temperatures, which in turn, make the system more heat. Thermal runaway is a very common phenomenon, from the concrete curing (heat) will release a large number of physical and chemical processes of stellar explosion (supernova is a product of cosmic thermal runaway), are likely to appear thermal runaway.

The apple lithium-ion battery thermal runaway. Such as both ends of a 9V battery is a coin bridging the tear film-like isolation of the anode and cathode of the sony battery will cause a short circuit, short circuit often will cause thermal breakdown. The cause of the fire of the asus lithium-ion batteries also include: ambient temperature exceeds 60 ° C, often overcharge unauthorized modification shell.

Whatever the reason, cobalt oxide experienced this reaction are samsung laptop battery chemicals. Valence Technology R & D vice president Joe La Mule (Joe Lamoreux) explained: “If you heat the chemicals reach a certain temperature, it begins to self-heating, and then developed into a fire and explosion.” In some case, such an organic electrolyte releasing the pressure will cause the cell to rupture. If exposed to high temperature environment, or is experiencing a spark, it may also will burn.

Although this uncontrollable reaction does not happen often, but the base number of the lithium-ion compaq battery is too large, we feel that such incidents often occur. For example, in 2006, almost all the major laptop manufacturers – Apple, Hewlett-Packard, Toshiba, Lenovo, Dell and other companies – have received a report of a small amount of ibm laptop battery overheating condition recall products. Single apple a 9 report in the recall of 1.8 million units PowerBook and iBook. More importantly, the number of the lg battery size, configuration and the battery cell (cell) will affect the intensity of thermal runaway.

Small battery pack (such as digital SLR cameras) are only a few battery power, thermal runaway propagation from the battery unit to the other unit is relatively low. And 787 huge batteries for dell pack is another matter: they are packed in sealed metal box, which can not be discharged waste heat, the result is that when a battery unit hot enough to ignite the electrolyte, and the rest of the gateway battery unit will quickly with into.

But you also do not need to worry too much. Your notebook is not a ticking time bomb. To do some maintenance on a regular basis, the lithium-ion batteries for lenovo will be safe and reliable work. Lithium-ion life is not long, generally two to three years can be maintained (whether you use it). Because of this, all of the hp laptop battery pack should be about every 36 months on the replacement. Moreover, whenever the charge is reduced to 50% of the time, you should can it enrich my knowledge. No memory effect of lithium-ion, but the voltage is too low will make them serious damage.

Within 1 year Asus N61Jq Battery life shorter time, more often than not because of the the battery normal aging, but because the battery in the number of charge and discharge process, the notebook BIOS system battery power a miscarriage of justice. Original battery there is a certain power, but the BIOS is wrong to think that the batteries are depleted, books forced shutdown. This Dell Latitude E6320 Battery life has shrunk, and the first not to busy conclusions battery quality problems, and the Dell Latitude E6420 ATG Battery correction “by such a simple way to let the remaining power into full play. How to conduct a battery calibration battery correction more than one way, usually there are three ways: using the BIOS battery calibration procedures manually battery calibration and use third-party battery calibration software. There is talk in front of two correction methods. Tips: do not recommend the use of third-party battery calibration software. As for the reason, you first need to install third-party software, the first two methods is simple; Secondly, in fact, behind the correction principle is similar, and not too many unique third-party software, but also there is a potential security risk. So, in the case of battery calibration can be completed by the previous two methods do not recommend the use of third-party software. Standard calibration method: the Dell Latitude E6430 Battery calibration standard calibration method: using books BIOS battery calibration function many brands of notebook computers in its BIOS integrated battery calibration procedures, the general statement in English is called “Battery Calibration”, namely ” battery is proofreading. ” Direct access to books BIOS battery calibration operation can be done, Asus notebook, for example, simple to talk about how to operate the other books of the mode of operation is similar. step 1: boot, the boot screen appears, press [F2] to enter BIOS menu; through the left and right arrow keys to select the Power menu. step 2: enter the Power menu, you can see “Start Dell Inspiron N5010 Battery Calibration” option (Figure 1), select it and press the Enter key to perform. ● 1 Select “battery calibration procedure step 3: At this time the screen turns blue, and English prompted to plug the notebook power adapter to charge the battery. And so the Asus A42-G73 Battery is fully charged, the screen prompts the user to disconnect the power adapter (Figure 2). After notebook began continued to discharge the battery until the battery power consumption Jing ● Figure 2 according to the on-screen instructions step 4: This process will take some time, and so the battery is depleted to automatically shut down, and then plug in the power adapter to charge the Dell Latitude D620 Battery, but Do not switch. Charging is complete (charging indicator goes off), and the battery calibration process is completed. This operation is the official battery calibration approach, the whole process takes about 4-5 hours, and time-consuming. If you find your laptop battery did not take a long time, such as a few months, life is not as good as the original, and with this feature books BIOS, proposed it. Cottage correction method: cottage correction: books boot natural discharge and some notebooks, to find how to find the Asus G73JH Battery calibration option in the BIOS. Is this laptop battery calibration can not hold it? In fact, we can “cottage” battery calibration method its operation. The reason is called “cottage”, because this is not the official method, but by some of the settings manually, so that books work properly discharge until the automatic shutdown. Tips: the principle of “cottage” battery calibration surface point of view, the Dell XPS M1730 Battery calibration process to charge and discharge the Sony VGP-BPS24 Battery, but its purpose is not to like what we imagine as to activate the battery, because the lithium notebook batteries are now battery, does not exist the problem of activation. The charge and discharge of the real purpose is to allow the computer to re-recognize the capacity of the battery. So, you want to try to call on clean, so that books work in smaller power, such a correction effects go

Ion battery protection circuit includes overcharge protection, over current / short circuit protection and over-discharge protection, requirements overcharge protection of high-precision, protection IC low power consumption, high withstand voltage and zero volt rechargeable

This paper describes three principle of the protection circuit, require new capabilities and features.

Lithium acer battery has small size, high energy density, no memory effect, high cycle life, high-voltage battery, and the advantages of self-discharge rate, and nickel-cadmium, nickel-metal hydride toshiba batteries are not the same, must consider charging the lithium battery, discharge of security to prevent deterioration characteristics for lithium battery overcharge, over-discharge, over-current and short-circuit protection is very important, and usually in the battery pack design protection circuit for

Protection of lithium apple batteries.

Due to the high energy density of lithium-ion battery, it is difficult to ensure the safety of the battery in the state of excessive charging, the sony laptop battery temperature rise, the energy will be excess, so the gas is generated by decomposition of the electrolyte occurs autoignition or the risk of rupture due to increased internal pressure; In contrast, in the state of excessive discharge, the electrolyte is caused by decomposition of gateway laptop battery characteristics and durability degradation, thereby reducing the number of rechargeable.

The lithium-ion battery for asus protection circuit is to ensure the safety of such excessive charge and discharge status, and to prevent deterioration characteristic. Protection circuit of lithium-ion battery protection IC and two power MOSFET, which protect the IC monitors the samsung battery voltage When excessive charge and discharge status switch to the plug-in power MOSFET to protect the battery protection IC features over-charge protection, over-discharge protection, and over current / short circuit protection.

Overcharge protection

The overcharge protection IC principle: when external charger for charging a lithium battery, to prevent the temperature rise caused by increased internal pressure, the need to terminate the car charging status at this time, required to detect the lenovo battery voltage protection IC, when it reaches 4.25V (assuming battery overcharge point 4.25V) that activate the overcharge protection, power MOS from on to off, and then cut-off charge.
In addition, you must pay attention to the overcharge detection malfunction due to noise generated, to avoid judgment for overcharge protection. Need to set the delay time and delay time can not be shorter than the noise duration

Over-discharge protection

Due to decomposition of the electrolyte in the case of excessive discharge and cause the deterioration of the battery for compaq characteristics and to cause the reduction of the number of charge cycles. Lithium battery protection IC can avoid excessive discharge phenomenon occurred, the battery protection function over-discharge protection IC principle: In order to prevent the lithium excessive discharge of the dell battery status, it is assumed that the lithium battery connected load, over-discharge protection will be activated when the lithium battery voltage is lower than the over-discharge voltage detection point (assumed to 2.3V), the power MOSFET transition from open-off cut-off discharge to avoid ibm battery over-discharge occurs, and keep the battery in a low quiescent current standby mode, the current at this time only 0.1uA.

When the lithium battery for lg connected to the charger and lithium hp batteries voltage higher than the over-discharge voltage, over-discharge protection be lifted., Taking into account the pulse discharge, over-discharge detection circuit has a delay time to avoid mistakenly action.

Should try to avoid light depleted rechargeable Asus a42-g73 battery power, because this will give the 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 battery is 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. 
Laptop battery without charge after the battery is fully utilized 
Notebook batteries are lithium batteries, lithium batteries, run out of 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 Asus g73jh laptop battery life is fixed ,300-600 charge and discharge times, and generally available for 2 years. 
How to save asus 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 the battery out to use, both to guarantee Asus G74JH battery good state of preservation, but not so the loss of damage to the battery runs completely.

One of the characteristics of the laptop is portable, so standard battery inside the battery management chip and charge the program automatically manages Asus g74 laptop battery charging and discharging including what time charging? Remaining capacity of how many? Need for depth charge and discharge? So automatically record and manage
Proper to charge the laptop battery 
Should try to avoid light depleted rechargeable battery power, because this will give the Asus G73 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 Dell latitude e6420 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 battery is 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 Dell inspiron 14v battery should recharge all used this idea is wrong.
