Last week I buy a Dell notebook from Dell.com, then I want to know some laptop battery tips and problems by google. I found many frequent asked questions about laptop battery, but there are various answers for them. So I send a email to laptop battery expect “Jack Smith” in http://www.laptops-battery.co.uk/ about these doubts. He reply me in the August 11, below is the reply content.

What is the six months warranty laptop battery?

Generally the laptop battery quality warranty is one year, but we can find many 6 months warranty “Original laptop battery” in ebay and other online shops? What is these six months warranty laptop battery?

Most the six months warranty batteries are the old battery with the new cells, old original battery shell and protection board. You can find the detail introduce here “How to replace battery cells inside laptop battery“. As the battery protection board is old one, so the laptop battery can only work properly about six months.

For laptop battery, the higher capacity the better?

For different models (particularly different size) battery, the higher capacity battery can work longer. Exclude the size and weight factors, of course that the higher capacity the better.

However, the same battery type, the same nominal capacity (for example,Inspiron 6400 battery 6600mAh), the actual measurement capacity is different: for example One Inspiron E1505 battery capacity is 6600mAh, and the other is 6700mAh, then the 6700mAh battery is better then 6600mAh?

The actual situation may be that : In the high capacity battery’s electrode materials, increase the initial capacity of more things, and reduce the materials to stability of the electrode. It may result that after used for some charging-discharging cycles, the capacity of high-capacity battery reduce rapidly, while the capacity of low battery is still strong. Many laptop battery manufacturers often use such method to produce the high-capacity battery. After used for six months the GD761, KD476, TD347 battery standby time is too less.

Enhance the battery capacity can reduce the battery cycle life. If the laptop battery manufacturers are not make great efforts in battery material, it is impossible to truly “improve” the capacity of the battery.

It is worth to store the fully-charged battery

Lithium-ion batteries have a very bad characteristic, that is the lithium-ion laptop battery aging time. When a lithium-ion battery in storage for some time, even not in recycled, its capacity also lost in the storage. Because the lithium-ion battery anode materials begun the failure process when manufactured. Different temperatures and Latitude D830 battery charged state cause the different consequences statute. You can the get the general conclusion by following data ( the percentage of capacity in the form):

Storage temperature – 40% state of charge ——- 100% state of charge

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

That is the all, hopes that can help you.

In this article, you will learn how to extend the charge life of notebook computers. If you are going to fly or drive long distance, these steps can help make the laptop battery last long, and then as usual, so that riding a little pressure. There are many simple steps and some of the more complicated steps, but in the end, I was able to fulfill my 8-hour charge for one year old laptop battery. The results will be different notebook computers if you have a low efficiency of the CPU or high-speed hard drive gain would be less, but usually you will get more out of a charging time.

In some cases, follow these steps could even extend Latitude d430 battery life. This means that 100 U.S. dollars or more savings. This notebook computer is used in Hewlett-Packard Pavilion DV5130ca Size: 2.0 GHz Processor – AMD Turion 64120 Gigabyte 4700 switch to support Broadcom 802.11b / g wireless network card 128 MB ATI Rage Mobile Windows XP MCE 2005 operating system, all other specifications are far outweighed by the power configuration computer management

So for those who do not want to enter the Setup program, and buy a new Dell Inspiron E1505 Battery , these are some simple things you can do to extend battery life. 1. To reduce the minimum readable display brightness level. In most laptop backlight like "compact fluorescent" (cold cathode) light bulb. They really drain your battery very quickly.

2. Turn off your WiFi off when you do not need it. The Fi card is another power equipment. Think of it – when you want to use your cell phone call, the discount laptop battery drains quickly, but if you just play games or listen to music, it can continue for a long period of time. This is the same idea. Wireless cards, "call" hot spots all the time. Even without a hot spot or so, this is a constant search.

3. Use Windows power management to control the original of your CPU. When unplugging from the wall, click on your taskbar, and then click Maximum GD761 Battery Sony VGP-BPS8. This will extend the life of your laptop, because your CPU will be reduced to a slower speed. (Continue to reduce your CPU, because it makes your battery recharge time, a huge difference in reading speed and better explanation.) 4. Unplug unnecessary peripherals. Unplug the USB lights, or your wireless mouse, when you no longer need them. Although minor, these devices can give you a few minutes for those additional charges.

In the Windows power management is quite primitive compared to the terrible free web on a number of projects. In the power management application, I use is called "SpeedswitchXP". It provides more choice, you control when your CPU speed. It gives you the option to set the maximum Dell Latitude D420 Battery. This setting will reduce the speed of your CPU, the minimum will go to. In my case, it is 800 MHz. I know this sounds ridiculous, but this is actually a very useful speed. I can run Media Center and play their favorite TV shows and forget I was running slow. This is also a very good word processing and play a simple game. The package also provides a dynamic switching.

When your computer power supply requirements, it will automatically hit the CPU speed to suit. If I suddenly decided to play the game of the earthquake, CPU will jump to the full 2000 MHz. I usually do not like to play Quake recommended intensive games, because it raised the pressure on the Inspiron 640m Batterydischarge so fast, it actually damages the cells, reducing the total number of charges, they can not have. Google this program, but also are similar in nature and many other issues.

This last step is unnecessary, unless your Pavilion dv6000 Battery will no longer hold the amount of time available for the cost. Although it gives you the total length of the battery life of the great benefits. To a similar battery, as well as shops, buy a new laptop computer batteries. There are usually two types of large-capacity and standard size battery factory. I strongly recommend a high-capacity battery. This is the main reason, I have made 8 hours charge. High-capacity Toshiba laptop battery more often than the stock battery, so that more of the charging time for more cells.

Must be regularly discharge the Pa3450u-1brs battery at least once over two weeks. Equally important is not to put the battery on the large deformation. I do not recommend charging your iPod, Internet, wireless networks and burning, while a movie. Practices, for their batteries more quickly, they can be safely discharged from hospital discharge pressure. This will result in damage to the internal chemistry due to excessive heat. The most important use of common sense!

This article went to some useful tips and steps to install solar lights security, including location, solar motion and the solar roof, wall or building safety of the increasing number of small solar panels.

A safe solar lighting is a great way to ignite the door, deck, driveway or parking lot and power your XPS M1310 battery! Here are some tips to successfully installed in a house or wall solar light’s motion.

First, find a good place to install solar-powered security situation in the solar light that you want to shine the motion. This should be a place such as solar light can be detected to a safe range of motion, such as solar lights will also be motion light shine on your need it. The surface should be fairly flat, suitable for installation of solar lights in its motion and XPS M1710 battery.

Step 2

Second, find a good place to near the little sun panels, solar photovoltaic cells can be charged security. Sitting in what position it should face south for solar panels to get as much as possible the motion of time, sufficient sunlight during the day. Take a look at the entire on-site the number of sunny days in order to ensure that the location of solar light to obtain maximum solar motion. Look for possible sources, such as shade branches, hanging and other buildings, Vostro 1720 battery or any other may give rise to pairs of solar panels for your safety covers. Sunlight motion of solar panels to be, a better chance that it will fully charge the battery every day solar security light for more time.

Step 3

A line will be connected to solar motion and micro-solar panels. Measuring line, take a look at how long it is. Once you have selected the solar-powered security situation in a good location and solar panels, to find a place to go between lines of solar panels and solar light’s motion. Measurement and safety of solar lights and solar panels of the distance to ensure that your cables and Vostro 1710 battery will reach somewhere in between.

Step 4

Solar security light into the small of your choice on the roof or wall and install solar sports solar panels point where you want to shine the light. Run the line between the two to ensure that the building walls or the motion of solar light in Vostro 1520 battery , security line. If the area is large, you want light, you can even add other solar-powered security situation and found a broader field and light motions.

Step 5

Congratulations! You now have a solar security light is not necessary to maintain the freedom of power lines. Your solar light and Vostro 1510 battery has a motion detector built-in mobile, security, solar energy lamp with adjustable delay time, best of all, you are a force for freedom the motion of sun’s rays from the sun, the power automatically.

IBM released its new ThinkPad R50 series during the fall of 2003. The R Series of notebooks from IBM used to parade as a budget class, that¡¯s no longer the case, the R Series is in fact quite close to the high-end T Series in performance and specs. IBM’s new drive-protection technology senses rough handling and parks the hard drive heads. Should the notebook hit the deck, the drive and its data are likely to remain intact, even if the computer itself is damaged and becomes unusable.

IBM Thinkpad R50
? Centrino 1.4 GHz Processor
? 512 MB DDR333 RAM (CL2.5 according to IBM, no data on memory timings)
? Radeon 7500 Mobility w/32MB Ram
? 5400 rpm 30 GB Hard Drive
? AC Power
? Rechargeable Thinkpad R50 battery

AthlonXP Powered Desktop Computer
? AthlonXP @ 2.26 GHz Processor
? 1 GB DDR424 RAM (2-2-3-5)
? ABit NF-7 nForce2 mobo
? ATI RAdeon 9700Pro w/128 MB Ram
? 7200 rpm 120 GB WD Hard Drive w/8MB cache

The R50 is based on the Intel Centrino standard, so inside you’ve got a Pentium M processor running at 1.5GHz. The ThinkPad T42 Battery memory complement is a fairly standard 512MB with one SODIM slot left empty for future upgrades, while the 40GB hard disk is smaller than some, but still more than enough for most notebook users. If you do want to free up some hard disk space, IBM has been thoughtful enough to include a DVD/CD-RW combo drive, so you can burn important data off to CD.

The R-Series actually has some advantages over its top-of-the-line sibling: The R50 and IBM ThinkPad T61 Battery comes with either a 14- or 15-inch display; the T-Series offers just the 14-inch screen. And because the R50 uses the industry-standard 12.7-mm removable-device bay, you can swap in a rewritable DVD drive (for $400 more). All you can get with the T-Series is a CD-RW/DVD ROM because of the 9.5-mm bay that IBM hopes will be a standard eventually.

The ThinkPad R50 IBM ThinkPad X60 Battery of course features IBM¡¯s easy to distinguish classic black case and with a 13¡± x 10.4¡± x 17¡± (W x D x H) dimension specs we see that it has grown slightly from the previous generation. With a 15-inch XGA screen (14.1″ also available) and weighing a modest 6.6lbs, or 7.1lbs when combined with the AC adapter for travel weight, the ThinkPad R50 can serve as a good desktop replacement or as a reasonably mobile laptop if you¡¯re on the go. The ThinkPad R50 is a diverse laptop, so let¡¯s dig into the details and see if it¡¯s worth your consideration for purchasing.

Like most ThinkPad notebooks, the R50 IBM ThinkPad X60S Battery is not a music machine, despite its smoothly designed, press-and-hold volume controls. Sound quality is fine, with no distortion or extreme tinniness, but ultimately the audio emitted is too low for more than occasional listening.

The R50 IBM Thinkpad X61 Battery ships with Windows XP Professional pre-installed, while IBM has thoughtfully also included a copy of Norton Anti Virus 2003. I use Norton myself and I find it alarming how many email viruses it spots on a daily basis, so it’s good to see it included with a new machine. ThinkPads also ship with a few special features like the hard disk Active Protection System. This basically stops the hard disk from damaging itself if the notebook is bumped or moved during operation.

Performance is fairly close to the Dell Inspiron 510m that we looked at last week, although the 3D performance is far superior on the R50 ThinkPad T40 Battery. Mobile Mark reported a battery life of three hours 42 minutes, which is good, but not spectacular. At least you’ll be able to squeeze half a day’s work out of the battery.

In conclusion, IMO the thinkpad r50 is a very good laptop select as its price $1,769. If you buy a laptop for General office work and study, the thinkpad t50 is your best choice. It is so thin and light that you can easy to take it to anywhere.

First of all, the test voltage to zero, the machine can not start naturally, can not use power when charging (the battery light does not shine).

Disassemble the battery, more or less talk about the situation inside the battery.

Battery in a total of 9 can be placed 18 millimeters in diameter, length 65 mm core CGH18650 models the location of lithium batteries, Panasonic’s 22 batteries in parallel, three groups of series (OK, then my new Latitude D620 battery, the same, it appears that is 6), there is a very fine control with a single chip – the protection of the circuit, the circuit to the computer a total of five output contacts, respectively, are negative, the clock and data.

First of all, check the sticky in the battery temperature detection probe (temperature resistance), and temperature protection insurance, are also normal. Test-retest the battery voltage of each group, in which two sets of battery voltage of 3.8V, normal; a battery voltage of 0V, appear to have lapsed. The total battery voltage of 7.6V, then the failure of the battery pack has not yet open, then measuring the internal resistance was very small, almost in a state short-circuit.

First of all, failure to deal with Thinkpad T60 batteries, battery repair based on previous experience, the failure of the battery may not be completely damaged, can be activated through a number of methods, in particular the performance of state for the short-circuit the battery. The voltage of the battery to 0 with one end connected to the circuit board off line to avoid damage to circuit boards in operation. Open-circuit battery voltage after the re-survey, is still 0V, ruled out the possibility of short-circuit boards.

For short-circuit the battery failure, the method is more effective high-voltage electric current moment method, using the old IBM power supply (my back-up power), 16V maximum 3A output string on the multimeter (a tributary of the current file 20A), first negative power supply Even with the battery anode, and cathode power multimeter then red table pen, table pen with black multimeter battery cathode touch, speed, faster as far as possible, the former two degrees to see the multimeter has reached close to the 2A (moment) and the third on only 0.4 A about an immediate stop, measure the battery voltage has been restored to about 3V, the internal battery short-circuit that point has been an instant high-current boil (If you do not damage the battery to stop immediately, even if so, battery life and capacity have been the impact, if conditional, or recommend replacement, but if the replacement, then try to replace the entire battery pack are). However, the batteries need to be a separate charge (if the battery charge of the whole group, this will result in the other two groups had mesenchymal cells), plug in the charger to start charging ammeter to monitor during the charge current to 500mA or so, current for the 3.6AH battery pack is small, but the charger is the charge current is limited and a small current to the xps m1330 battery charge is good for the resumption. After about six hours, the charger showed the battery is already full, continue to re-charge for about two hours, remove the battery, measure voltage has reached 4.2V, with bright halogen bulb in the flashlight (3V, 500mA) to discharge its , bulb sharp discharge current of 700mA, the battery pack that has been basically restored, continue to discharge until the battery voltage down to 3.8V, the purpose of the two groups with the same battery voltage, charging time together so as not to overcharge the Back to the whole battery pack battery circuit welding.

Since the inspiron 6400 battery voltage while the circuit board there is no output, then, surely have damaged circuit boards, after observation, negative input circuit board (take battery) output (then output contact) is directly connected, and the positive input and output of by a high-power thyristor control, the thyristor remains cut-off state, that is, the control circuit has not been output control signals to the SCR control terminal, or simply the SCR has been destroyed. (Measured after the control signals that I did not) because I do not have the ability to repair single-chip microcomputer. IBM to take into account the protection of the BB more perfect, is about to run out of battery power will automatically shut down when, this battery is intended to be used for entertainment, therefore, need not be too concerned about, so I decided to shake the hp battery protection circuit, directly depend on BB’s protection circuit. SCR is in the input and output pin (that is, cathode circuit board input and output pin) between the solder on a small 2A fuse, fuse 2A select the reason is based on current usage, the largest in the computer power consumption , the current does not exceed 1.9A, 2A capacity sufficient unusual circumstances (for example, short-circuit accident) but also to ensure that the fuse of the time, but also play a role in protection.

In fact, directly to the SCR control terminal so that it can also be a high turn-on, but taking into account the current the battery must be a reason to burn, and the reasons for the identification of protective measures taken before or better in order to avoid greater loss.

Well, the battery power has been the first non-stick, and on the machine to try it! Normal boot, plug in the power immediately after the charge on the flashing lights are up, the way when charging the battery with a random look at battery information management software, was also displayed, the battery circuit board This shows that the single chip is still working.

Batteries battery is a Panasonic, the time the factory in June 2000, the first time in October 2000, the design capacity of 38.88Wh, the current capacity 38.88Wh, is charging cycle: 0 times.

Oh, do not know how to engage in, the inspiron 1300 battery may be burned when burning confused, even cycles to the zero, Now it maybe a new battery.

Repair battery step two : repair battery shell

Points and then encountered trouble: it was soon filling power (twice as fast than normal), in the course of discharge to 70% of the time will suddenly prompt “The battery is dead, please insert the AC power supply” warning capacity to show an immediate 5%. The beginning of a long time thought it was not using the battery leads to memory effect, we should do like a few of the deep cycle. But after several full charge, after release and found that the improvement is very small, only about 45 percent take power, with half an hour, we still have the problem. The largest may be the Inspiron 1520 battery pack in more than one section or “black sheep” in trouble, have to pull it out!

Red several times in the subsequent discharge cycle every place is full of electricity and have finished after the battery power to open, measuring the voltage of each battery pack to find a group of “different”: the per-charge when it voltage to reach 4.2V or even more than the first, leading to cessation of the entire VGP-BPS2 battery charge, and discharge when it was first to reach 3.6V or even less, is a typical decline in capacity. And the largest of which may still be a battery problem. This group of cells separated from the measurement of voltage, respectively, found that a battery voltage is low, only about 3.2V, a separate charge of their voltage quickly reach 4.2V, less than a minute of time, The A1185 battery basically has no capacity to speak with a light bulb when the discharge was found, it has the fundamental output current that can not provide even less than 1mA, measuring its resistance, has reached more than 2K seems to have been scrapped.

As a result of a “shock therapy” after the restoration of the normal cells, but not charging voltage reached 4.0V, it seems that it is “the pot boiled dumplings – do not put out an electric” soldering it back a battery discharge followed by the use of time of up to 90 minutes, has been near normal level of the battery.

However, when the charge is quickly filled, and disturbed mind up soon. Was a discharge, it is less than half an hour, open a test, just fix the bad and the battery.

Not always have to use a “heart to recover,” ah, so the value on the lost.

This section of the final decision to do a battery operation, and then they can not, then replaced the batteries. Peeling of the batteries, removed the insulation near the cathode cap and found a slight corrosion around, but I do not like battery leakage and traces, as well as save. With halogen lamp from the battery positive and negative, there is no response Taking into account the previous “Anatomy” the same symptoms when the batteries are inside the battery with the battery cathode output between cathode cap (the pressure on, not welded) oxide occurred, resulting in increased resistance and end-of-life battery , and the internal battery is still good. Oxide layer in the case is not serious as long as the battery cap to strengthen the internal contacts and battery resulting in the battery does not leak if damaged can be restored. The simplest way is to step up the battery forceps are negative (one pad insulation film), while measuring the inspiron E155 battery output voltage (or current), while vertical extrusion batteries, once the battery output voltage is increased, the current increase (the change is often the jumping in nature, relatively large changes) to stop immediately, the battery will be able to repair.

The top edge of the battery cathode cap next to the mouth ventilation valve with cutting pliers, then immediately measured and found that the battery has been restored, the output current increases immediately. In order to insurance purposes, the battery cap in the week between the edge of the chisel a few more in order to increase the contact area to ensure that the use of effects.

The battery to re-wrap, solder back to the XPS M1210 battery pack, charge, discharge. The use of time to reach more than 90 minutes.

Again measured with test software and found that the current capacity of smaller 38.88Wh from the original into a 32.07Wh, a decrease of nearly 20 percent, but this is the real discharge process, there is no jump of dropped. After several red discharge cycle, the capacity has increased by some. Use has been made to the current two months, everything will be all right.

During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPS9/S battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that ThinkPad R40 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R50 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

We prefer laptop to PC most for portable office work, the laptop battery is the most important part of the laptop working.So we must take a high attention to the laptop battery life.

We say the laptop battery life is not the laptop battery working time, but the battery working time determine the laptop battery life. Also the laptop battery life means that the using time (charge-discharge cycle of the battery). Generally this number always between 400-600 cycles. So we can prolong the charge and discharge rate to extend the battery life. That means you must try your best to extend the laptop battery working time. Also we can hack and revive the “dead laptop battery” to extend the laptop battery charge-discharge cycle.

As we all know, usually the 6 cell capacity laptop battery are only can last work for 2-3 hours in natural working. So we can extend the laptop working time by using the following tips:

Use high capacity battery : You can choise the higher capacity battery for longer working time. The inspiron 1300 battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery.

Only run what you need. Keeping programs running in the background will require more system resources, and use more of the precious battery juice. There’s a reason that some programs load slower than others, and that’s because they need more system resources. Try to keep as few programs as possible open, and avoid programs that slow your computer down even at the best of times.

Dim the Lights :
Turn down the brightness of the LCD panel (via the Function-key combo, or in the Control Panel’s Display Settings dialog) to the lowest level you can tolerate. The backlight sucks power like the Rockefeller Center Christmas tree.

Charge and discharge : For lithium ion XPS M1210 batteries, you do not need to discharge them fully and recharge constantly. Since they don’t have the same “memory” as older nickel-metal hydride batteries, it is actually better to discharge a lithium ion only partially before recharging. You need to do a full discharge only about every 30 charges.

Be careful with the external peripherals too. Unplug USB devices, PCMCIA devices and any other crazy things you’ve got plugged in if possible. as your system uses power to interact with them.

Run your laptop in less performance : the more performance of laptop, the more power expend.

Take out your battery : Consider removing the inspiron 6000 battery from a laptop when running on fixed power.

Carefully maintain your battery : keep your battery in dry clean and cool place. Wet and dirty can erode your laptop battery. Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up. Your battery is a lot less efficient when not within its standard operating temperature range.

Revive dead laptop battery : continue use dead battery by using some methods to activation them.

All along, many consumers often complain that their laptop battery standby time is always shorter than the manufacturers claims. For this question, the laptop users must realize that. The original notebook manufacturers announced running time is standard time, that is the standard operating procedures time in the measured values. But the manufacturers want to make the value “more attractive”.

So in the test time most manufacturers will reduce the notebook power consumption. For example: Lower notebook LCD screen’s brightness , close the CD-ROM the wireless card infrared and Bluetooth; Donot run large-scale software in the operating system, play video, power management settings will be adjusted to optimal Dell XPS M140 Battery performance;

Or even just boot into the operating system and do not run any other programs. In this way CPU, hard drives, memory, screen and other equipment will be in a very low-power state. But users usually use the notebook in the normal power consumption. So users battery standby time is shorter than the manufactures claimes.

Laptop battery duration is very important for the users. Mobility is the soul of notebook advantage. If the laptop leave the power the Inspiron E1405 Battery is most important to run the laptop. So laptop battery standby time is an important indicator which can not be ignored.

For manufacturers, what is the point of the Apple PowerBook G4 15 inch Battery life? First of all, we all know, there are only two ways to increase the battery usage time. First is increase battery capacity, the second is to reduce the power consumption of the hardware. However, to manufacturers “added the amount of not to raise fares” is almost impossible.

In the hardware side, now the most laptop basic framework are similar, each brand notebook power consumption are in the same level. Only one possible way is to carry out some small manufacturers optimize the circuit, coupled with a number of specially developed software to reduce power consumption. So it would involve a technical issue, for same configuration laptop and same capacity PowerBook G4 12 inch Battery, longer battery life, the better laptop technology.

Second, the longer battery life can be used as a vendor hype of the highlights. That will help to improve their brand awareness. Finally longer Apple PowerBook G4 17 inch Battery life time is often able to attract many customers eye to buy the product. Which is the most important point to manufactures.

Because of the points mentioned above, in reality, manufacturers used to mislead consumers consumption practices. Because manufacturers customarily used such tactics and many users are fooled unaware of the circumstances.

Customre Reviews :

this Dell laptop battery is a nightmare. i bought 2 defective ones in a row and now dell will only refund one of them. the first one didn’t charge at all. after 2 weeks, the second one doesn’t charge past 5% of its capability. Dell will not refund me for the first one because their agents never connected me to the right # after I purchased the second one. Now i am over the 21 days. Dell has problems.

This battery only lasts a few months when I checked the price for a replacement I got shocked. I will try other batteries not from dell and check quality and price, maybe I can get the same performance as the oem but without wasting more money.
