For most dell laptop consumers, the short battery lasting time has become a common problem nowadays. There are many factors that can affect how long your laptop can run. In the early stage of purchase and use, there is something we should know to avoid such a problem.
It is well known that the laptop running time in battery mode will be affected even if the brightness of laptop screen is increased a little, or an additional memory card or a mouse express card is added. Therefore, it is realistic to say that laptop battery life issues will always become the headache for we consumers, at least there will be no qualitative change in a short period of time. Then are we really helpless about this and accept the reality that the 3-5 hours dell inspiron 1545 battery life is gradually reduced to one or two hours? The answer is negative.
First, we should try not to use laptop in battery mode. Instead, we could use the AC adapter to power the laptop. Don’t expect that the dell 1545 battery will give you a 9-hour running time. Second, we’d better not use too many external devices and functions. If possible, we could try to decrease the brightness of laptop screen, unplug mouse and use touchpad instead, turn off built-in network card or sound system, etc. In short, there must be some sort of “sacrifice” in order to maximize battery life, although it would be a painful experience to use laptop under such a circumstance. Last, we could prepare one or two more backup batteries, especially for those consumers who often use laptops in battery mode.
In the existing background of laptop battery technology, it is still like a dream to get a longer battery life for about 10 to 20 hours, especially when the lithium-ion dell laptop battery technology products still dominate in the market. To achieve such a breakthrough, there is still a very long way to go.
When buying a new laptop battery, consumers will always take battery capacity into consideration, because different capacity means different battery running time. Most of them know the capacity marked on battery surface such as 4400mah, 6600mah, 7200mah or even 8800mah (for example, you can easily find a dell inspiron 6000 battery in the market for the capacity of 4400mah or 6600mah), but maybe some of them do not know how many cells are there inside the battery.
At present, laptop batteries are generally divided into 4-cell, 6-cell, 9-cell, and 12-cell and so on. Usually 4-cell battery can last for about 2 hours, 6-cell battery can last for 3 hours, 9-cell battery can probably last for 4 hours, etc. However, it is hard to exactly tell you how long a battery can last, because it mainly depends on how you use the battery, as many factors may affect the battery running time. For ordinary home users, it is recommended to use the 4-cell battery, because a stable power supply is available at home. For office users, the 6-cell battery is definitely a good choice. For those who have high requirements of mobile work, they may consider buying a 9-cell or 12-cell battery.
There is also a formula to calculate how many cells are there inside a battery, provided you know the capacity and voltage.
Battery Capacity/2200mah or 2400mah * Battery Voltage/3.6v or 3.7v = Battery Cells
For example, your battery capacity is 8800mah and voltage is 11.1v, then you may calculate that it is a 12-cell battery.
From the day when laptop was born, debate about the battery has never stopped, because laptop running time is considered as an important laptop technologic index, which is mainly determined by battery capacity. Then how to make battery work at its optimal performance? Here are several mistaken ideas about battery maintenance (for commonly used lithium-ion dell laptop battery).
1. Shall we charge the battery for 12 hours at first use?
It’s not necessary to do so, because the laptop has complete power management circuitry and charging management system. When the battery is fully charged, the control circuit will automatically switch off. Once the battery is fully charged, it can be used at once. It is not that the longer the battery is charged, the more juice you can get.
2. To avoid memory effect, shall we fully drain the battery before charging it?
There is no need to fully charge the battery each time before re-charging it. It is proved that frequent and complete discharge of battery will shorten the battery life. It is recommended to charge the battery when the power is down to 10%. However, it’s not suggested to charge the battery when the power is above 30%, because the memory effect does exist.
3. Shall we take off the battery when laptop is powered by AC adapter, to avoid repeated charge and discharge?
The Answer is: No. You don’t actually have to take off the battery when laptop is powered by AC adapter. Also, you don’t need to worry about the battery being charged and discharged repeatedly. Most laptops are designed such a characteristic: When the battery power reaches to 90% or 95%, it starts charging (For example, most HP and Dell laptops).
4. Shall we fully charge the battery for long-term maintenance?
If you don’t need to use the battery for a long time, then you should pay close attention to the battery maintenance, because improper maintenance will affect the battery life. Usually, it is recommended to keep the battery in dry and low-temperature environment with 40% charge. If necessary, the battery should be charged and discharged at least once a month. The following chart will help us understand it more clearly.

There are always some consumers asking how long on earth their new dell inspiron 1525 laptop batteries can last. Actually, this is really a difficult question to answer, because there are many factors that can affect the dell inspiron 1525 battery run-time. In other word, the laptop battery run-time mainly depends on the power demands required by the laptop components. For example, the display, the hard drive and related accessories which can result in extra power depletion. Besides, the laptop design and the hardware plugged also play an role in reducing the battery run-time. Usually, Laptops and other small electronic devices share smaller and lighter batteries and are rated by their Volts and Ampers or Miliamperes (1 Ampere or Ah is equivalent to 1000 Milliampere or mAh). To learn the run-time of a battery or its Watt-Hours, the Volts and Amps are multiplied by one another. Generally, the higher the volts the longer the Watt-Hours, but this can still vary depending on the Amps. To calculate your inspiron 1525 battery runtime, you may take look at the formula below.
11.1 Volts, 6600 mAh (6.6 Amperes)
11.1 x 6.6 = 73.26 Watt-Hours
A 11.1 volt 6600 mAh laptop battery can provide approximately 73.26 watts for one hour. If you want to calculate how long your battery will last, you may directly divide the 73.26 Watt-Hours by your laptop’s watts. For example, if your laptop requires 21.2 watts per hour, your laptop will probably power for 3.46 hours. (73.26 battery watts/21.2 laptop watts = 3.46 hours of estimated runtime). Actually, this is just an formula and sometimes the run-time may vary depending on the components or any hardware running on the laptop.
Your laptop watt hour information can usually found in the user manual. Please bear in mind that the watt information does not include the use the additional installed programs, hardware or software. If you open other additional software or hardware, no doubt the runtime of your dell laptop battery will be reduced. In addition, wifi, video streaming or play games will also use up the battery power very fast. If you do some simple office work such as Word or Excels, the run-time will probably last longer.
Nowadays, laptops of different brands have been widely used among people, but few of them know how to fix the problem if the battery can not charge. There are several factors that may lead to battery not charging. Let’s take the dell inspiron 6400 battery for example and check those problems one by one.
The battery stops charging once you slightly move it. Sometimes the problem may come from the adapter, especially the power tip of the adapter is a little loose and can not fit the laptop tightly. If this happens, you may simply contact your laptop manufacturer for a proper adapter. When you use the adapter, make sure it is properly connected and the power tip fits properly.
The inspiron 6400 battery discharges very quickly. Sometimes, new batteries may behave erratically until they have been charged or discharged after several circles. If it is a new battery, you may try to charge and discharge the battery for a few more times. Usually the life span for a laptop battery is between 2 to 3 years. If your battery has already been used for about 2 to 3 years, maybe it’s the time to buy a new replacement battery.
The dell 6400 battery can not be detected by laptop. If the laptop battery is properly installed and positioned, but still can not be detected when you log in to Windows, there are two factors that may lead to the problem: either the motherboard of the laptop or the battery is defective. To troubleshoot the problem, you may first replace the battery with a working one. If the problem exists after you replace the old battery, the problem may result from the motherboard. It is recommended to bring the laptop to a repair shop and replace the motherboard.
The dell laptop battery can be detected, but the laptop immediately turns off if the AC adapter is unplugged. If this happens, maybe the battery is not seated properly or the battery contacts got dirty. You may try to remove and reinsert the battery for a few more times to see if it can solve the problem. Meanwhile, you may also use a brush or eraser to clean the battery contacts that connect the battery to the motherboard of the laptop. If it still does not help, you may try to replace the battery with a new one. However, even if replacing battery can not solve the problem, maybe you may check if the problem is coming from the motherboard itself.
Usually there are some consumers complaining that their laptop batteries could not charge. Take Dell Inspiron 6400 Laptop Battery for example, sometimes it is plugged in but could not charge. Hope this article could be of some help.
The most outstanding characteristic of laptop is its portability and ease of use, compared to desktop computers. However, the laptop is no longer portable if the battery could not work properly. It may function like a tethered desktop computer if the battery doesn’t get charged properly. Most of the major laptop computer problems are battery related and they need to be solved immediately. Sometimes the battery was plugged in but did not charge.
Actually, most of today’s laptop computers are loaded with a lithium ion battery of several hours. Of course, how long the battery will last is entirely determined by how you use it. To charge the dell laptop battery, an AC adapter with specific voltage settings is required, which is normally supplied with the laptop.
If your dell inspiron 6400 laptop battery is plugged but not charge, you may just check the following factors.
Defective AC Adapter
If the AC adapter is not working properly, then the charging won’t occur at all. A laptop AC adapter, with lower than required voltage settings, will not be able to charge the battery. See to it that the AC adapter matches the laptop battery’s requisite settings. A loose wire or internal breakdown may render an AC adapter useless. Changing the adapter all together might solve your problem.
Power Management Software Problem
Sometimes, the problem is merely with the power management software. This is the classic case, when the laptop charges when switched off, but doesn’t when the computer has booted. The software may have gotten corrupted which must be causing the problem. In such a case, go to the device manager section and uninstall the power management software. In case of Windows XP, uninstall ‘Microsoft ACPI Compliant Control Method Battery listing’ from the device manger section. Take care that you do not install any other AC adapter driver software. Then go for a ‘hardware scan’, which will automatically identify the Dell KD476 battery and reinstall the latest version of the drivers again. That will restore the charging facility of your laptop.
Internal Charging Circuitry Problem
If neither the AC adapter, nor the power management software has a problem, then problem can be with the internal charging circuitry of the laptop. In this case, there is little you can do other than sending the laptop to the manufacturer’s service center.
Another reason that could lead to the charging problem may result from a defective battery. Run the dell inspiron 6400 battery test. If your laptop is quite old, this could be one of the most likely reasons. Get the battery checked from the manufacturer and check if it has exceeded its predicted recharge cycle limit.
Some consumers may have the experience that their laptops could not successfully boot even the Type U4873 battery was installed and the adapter was plugged. There are many factors that may lead to such a problem. Let’s troubleshoot it one by one.
1. The AC Adapter
First, please make sure that the power outlet is in working condition and the adapter is properly connected. Some adapters also have indicator light which can show the power is on or off. Remove the AC adapter and some other external devices, including the battery. Then you may press the power slider or the power button for about 30 seconds to discharge the static charges that might have stored in the laptop. With the prolonged usage of the laptop, some static charges tend to stay in the notebook and these static charges do not allow the laptop to function normally. After that, you may connect the AC adapter and turn on the laptop. If the laptop does not turn on, please check the power LED of the laptop. If the LED does not turn on or there is no light coming out, then the problem is mostly with the A/C adapter.
2. The Battery
You may take out the AC adapter and some other external devices, and then remove the battery. Press the Power button for about 30 seconds to remove any static charges. Re-install the battery and turn on the laptop to see if it powers up. (Don’t connect the AC adapter now) If the laptop does not power up, the problem is probably with the battery. At this time, we may fix the problem by doing battery calibration according to the following steps:
a. Shut down your laptop.
b. Connect the AC adapter and completely charge the Dell inspiron 6000 battery.
c. Restart your laptop.
d. Press F8 key to boot into safe mode.
e. Disconnect the AC adapter and completely discharge your battery until the laptop turns off.
3. The Display
The laptop does not boot may also result from the fact that there is something wrong with your laptop display. So you may try to connect external display and see if you can get display on external display device. Sometimes the corrupted display drivers might be the cause for the problem of not getting the display on your laptop. You may fix the issue by updating or reinstalling the display drivers. Even check with the manufacturer website if there is any latest BIOS available for your notebook model. Close attention should be paid while updating the BIOS. If it is not updated properly or if you downgrade the BIOS, this will make your laptop to not work.
4. The Hard Disk
Sometimes the crashed disk can also be one of the reasons for laptop not boot.
5. System Files Corrupted
If the system files are corrupted, the laptop may not boot into windows. Then it is recommended to reinstall the operating system.
What will you do if your dell inspiron E1505 laptop battery has been used up? Maybe someone will simply throw it away as useless rubbish. In fact, many environmentalists all over the world are encouraging people to save the planet by not carelessly throwing their batteries away, especially the rechargeable ones. If your dell E1505 battery has stopped working, don’t throw it away.
There are two ways that you can do to properly dispose of the battery. First, you may directly contact Dell and ask if they can replace your battery for a new one either for free or for a nominal fee. Dell has what they call a “Battery Program” and you might be qualified to avail of a replacement. Second, you may drop by a recycling plant which aims to collect recyclable items. If you can’t find a recycling plant available around your area, you may search online or ask your local government for assistance. If the dell inspiron E1505 battery is recycled at the refurbishing facility, many materials inside it can be reused.
Recycling is one of the most important advocacies of today. Recycling batteries is not just a way to get rid of what you think are useless batteries. More importantly, we are doing the right things to keep our plant safe for future generations.
Nowadays, laptops have been widely used among people. However, most consumers just don’t know how to keep their Dell Inspiron 1525 laptop battery working at optimal performance. Although laptop battery is consumption product, with the increase of use times, its capability to hold charge will gradually degrade. If close attention is paid to properly using batteries, even cheap replacement batteries can exceed original ones in performance.
When charging the Dell Inspiron 1525 battery for the first time, it is recommended to charge it overnight. After the charging process is complete, it is recommended to unplug the adapter and let computer run on battery. Sometimes, new batteries may be a little hard to be completely charged until they have been charged or discharged after several circles. When this happened, you may try to charge and discharge the battery for a few more times. Also, please don’t charge the battery intermittently. In other words, don’t plug and unplug the adapter in a short period of time.
Another major element in maintaining your dell laptop battery is temperature. When the battery is taken out, don’t expose it to high temperature environment. If you are working on your computer on a soft surface such as carpet or a bed, air is unable to pass through and you may hear the vents turn on and your fans will be running all day drawing precious power from the battery. If you want to squeeze the most juice out of your laptop’s battery, find a hard, flat surface to use your computer to keep the fans running at a minimum. If the battery is not used for a long time, it should be preserved with 60%-80% charge. It is recommended to charge and discharge the battery at lease once a month to keep its chemical activity. The battery is made of precise electronic parts and cells. Avoid falling on the ground and heavy percussion.keep looking »
