The analysis of the laptop battery replacement cost

With the growing popularity of notebook computers, laptop battery is getting more important to consumer attention. A good laptop battery is not only give the great convenience for user's mobile commerce and digital lives, but also can eliminate insecurity of future use.  A bad laptop battery, for the user unable to meet their mobile digital life. It will also bring the hidden dangers to users, especially security issues. A battery explosion caused the destruction of a notebook, or even ohter serious consequences. So choose a good laptop battery is significantly thing.

However, the thinkpad x40 battery  original price is hundreds dollars. So that many users used to choice and better cost-effective laptop battery replacement. The laptop replacement market price is between 30 - 100 dollar. So it is difficult for consumers to judge its quality from the price.

In this article the author will help the customers to choose the best thinkpad x41 battery  from the current market. We will analyze the composition and design of laptop batteries to compare the battery price and quality.

Laptop battery is made up of a lithium-ion 18650 cells with protection circuit board and PVC plastic shell. Then we will analysis of their costs on item in the follwing steps:

1. There are three kinds of 18650 lithium-ion battery in the market: 2200,2400,2600 mA. A typical ThinkPad   X41 Tablet Battery with six battery assembly (Series 2 and 3). If it is a genuine original batteries, typically Japan and South Korea or domestic manufacturers A formal 18650 cells. These batteries have the quality and safety assurance through rigorous testing, the cost is usually in the 3-4 dollars (based on the different capacities).  So a normal laptop battery (6-cell) costs around 20 dollars. If B grade, or  batteries disassemble from the old machine (the quality and even safety issues batteries from Japan and South Korea). Their price between 1.5-2 dollar. Such Lenovo Thinkpad X61 battery  assembly or re-assembled into a 6cell laptop battery cost 10-15 dollar. In addition, even worse, some manufacturers use more poor illegal 18650, often have security problems (that can cause the battery explosion), its 6cell laptop battery only cost 8 dollar or less.

2. Laptop battery PCB control panel : a good control panel can extend laptop battery life and protect the safety. Its cost is usually 10 dollar; If it is bad dysfunction PCB ThinkPad X60 Battery  control panel, or board disassemble from the old machine, its cost is only 5 dollar.

3. Laptop battery PVC plastic shell, the cost of a good plastic shell is 5 dollar, a bad Lenovo   thinkpad x200 battery low-quality goods cost less than 1.5 dollar.

4. Labor, equipment, venues, with an average around 4 dollar each cell.

On the basis of the above , a good quality assurance laptop battery such as VGP-BPS9/S (6 cell) costs should be at 40 dollar. So a good 6Cell laptop battery replacement price (including operations cost and profit) is oftern 60-80 dollar in the market ; If it is a inferior quality goods, the market price is 40-50 dollar; If it is the lowest quality laptop battery (the cell and PCB control panel are both disassembled from the old machine), the price is 30-40 dollar.

In all the laptop battery quality is as its price. We should buy the suitable Sony   VGP-BPS8 battery in the market, do not take too much attention to its price or it is orginal item or not.

How to test a dead Battery Charger

By laptopsbattery - January 24th, 2010, 22:16, Category: General

How to test a dead Battery Charger

The dead battery charger means the charger can not work : can not charge the laptop battery or can not run the laptop. When our laptop battery can not charge, we must check the battery and charger state. Now let me list the steps of test our battery and charger below.

Make sure the powerbook g4 battery charger cable is plugged in and the output is to power.

Look closely at the battery. Is there corrosion or leakage? If so, replace the inspiron 6400 battery immediately.

Test the charger. For DC chargers, a voltmeter set at 25 VDC and touch the contacts with the probes. The meter should read about more than 1 V Evaluation of the shipper. If the reading is zero, change inspiron 6000 battery catheters.

Testing a AC charger through the establishment of a voltmeter to 25 VAC. Tap the contact probes. The transformer in the pa3399u 2brs charger is bad if you get no reading.

Check contacts. These are strips of metal or points in the appliance and charging cradle. With the Dell latitude d600 battery charger unplugged, clean with a cotton swab. Use a fine emery board to remove visible corrosion.

Power your notebook with any battery

By laptopsbattery - January 24th, 2010, 22:01, Category: General

Power your notebook with any battery

As we all know the laptop battery is important to our laptop. Some times when your laptop battery run out in the open air, what should you do? Go home to get a replacement. No no you need not. Take out your torch battery to power your laptop.

In fact, laptop batteries can be replaced with any other kind of offers it is right or sufficient voltage. Here I am with two 6V LIFEBOOK T4010 battery manipulated up to twice the voltage to the power of a Compaq Armada 110th.

Step 1 Remove power All you need for your old Fujitsu Lifebook T4020 battery to disassemble the battery, I was very stubborn and I have it only with a considerable distance to cosmetic damage, please try to set it apart from the contacts when the battery is connected to the laptop, I have but not real pictures of this step, as I have about 1 month ago, and I just un-earthed casing of the battery when you've received a little wrung from the battery housing to things either easier or a little more difficult was the Battery Compaq merged, so I was almost broken just plastic!

After the Lifebook T4220 battery unless you have some 9-cell battery, depending on the type of laptop was to find battery. You need to pull out all those bulky batteries, which certainly does not lead to rip the wire to the batteries from the board (Figure 2)

Step 2 Source improvise and power

To some batteries in the laptop, I have two Fujitsu Lifebook T4310 battery in my 5 million candle power torch, to assess each 6V to 12V to get as they were manipulated together for combined power, power, I do not know how long they modified battery is fully charged, but I guess at least 30 minutes. 100% CPU

If you have two batteries you need to red) to positive (a battery to the negative (black connect) from the other Fujitsu Lifebook T4410 battery .

Step 3 Connect power.

Now that they've been getting your Fujitsu Lifebook T5010 battery, the next thing to do is connect them to the leads of the laptop battery board, you have the positive of your new batteries to the positive lead connected to the PCB. I recommend that the cables of a decent length for a simple, but also tinged with red and black wires to the corresponding compounds battery (ie connected to red, red), it makes things easier.

Step 4 Replace remastered Battery

I had a small hole for the wires to pass from the Dell Inspiron 1721 Battery case, remember this and to do, so that the cables come in a handy place to do this if you do not want to spoil your battery housing provides good.

Step 5 Testing the new power

It must be said that I use to boot to the A / C power connector on the laptop, but after that it worked well without the A / C had power, I do not know if this because the laptop is old and it couldn 't was you know the batteries to boot the laptop, but it does recognize the Dell Inspiron 6400 Battery with the A / C power is connected and switched off the laptop.

This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.

Tech Specs:
Battery Type: Li-ion
Voltage: 11.1V
Capacity: 4400mAh
Dimension: 207.60 x 28.10 x 19.80 mm
Weight: 341g
Condition: Brand New, 1 year warranty!
Work with : Latitude D820 battery, Latitude D830 battery not competiable with the Latitude D620 Battery

Customer Review:

I have had other laptop batteries lasting well over two years. This one really disappointed me. It looks like in order to cut costs, Dell may have sacrificed quality.

From the looks of it, many people are having the same problem I have with the laptop battery. The battery was giving decent run times until it reached an age of about 20 months. After that, it went to about 10 minutes of run time.

While this is not an absolutely horrible lifetime, I typically have had Dell Latitude D830 Battery last about 3 to 3.5 years before this happens.

The Dell latitude D830 battery replacement reivew in Amazon:

I have a Dell D830 (purchased 1.75 years ago) & a Dell D820 laptop (purchased about 3.5 years ago). The batteries are interchangeable in these 2 and the old D820 battery has begun failing to hold charge so I bought the AGPTEK Super-Capacity Li-Ion battery. The Latitude D820 Battery arrived DOA, no status lights and neither Dell recognized it. I sent it back for $8.70 in postage and the replacement does work and so far is reporting a good charge: 3.5-4 hours in the Dell D830, which is about the same as the 1.5 year old battery reports. The replacement is only a month from manufacture if I read the code AGPTek pasted on it (it has 20090720 embedded in it), and both the dud and the replacement fit well in both my Dells. However with the cost of shipping the dead battery back this battery was not such a bargain.

Purchased the Dell Latitude D820 Battery in Nov 2008 and it worked as advertised for between 6 and 7 months. At that point it quickly lost the ability to hold a charge. It still works in that my laptop can run for about 15 minutes on the battery, however the battery has bottomed out and only accepts ~20% of the capacity it had when new.

My experience with original Dell batteries is that they last about 18 months, however the cost is much higher.

This replacement battery for a Dell Latitude D830 Battery lasted 3 months before the charge wouldn't last more than an hour. The original battery would run for 3.5-4 hours on a charge, and lasted for over a year. Now at 5 months on this battery, the computer tells me that my battery is "reaching the end of its useful life".

The Dell Latitude D630 battery customer review :

The Dell D630 battery that was included in this D630 laptop was unusable within a year of owning this machine. Dell will not replace their own defective part because it has been 1 year and 1 week since the machine was delivered. This laptop has already had the hard drive and the power cord replaced and based on other reviews, there is clearly a problem with the battery. After spending 45 minutes on the phone with technical support and no access to a supervisor, I will not use Dell to replace this battery.

From the looks of it, many people are having the same problem I have with the laptop battery. The Latitude D630 battery was giving decent run times until it reached an age of about 20 months. After that, it went to about 10 minutes of run time.While this is not an absolutely horrible lifetime, I typically have had batteries last about 3 to 3.5 years before this happens.

The Product Dell Latitude D630 battery replacement in Amazon review:

My battery lasts for 2 hours after 2 weeks of use(after following best practices of charging/discharging) which I would consider poor performance even after relatively cheaper price as compared to Dell battery that would last for at least 4.5 hours after 3 months of usage. I had to struggle a lot to fit the battery on my Dell D620. I would think twice about buying cheap as it may also be cheap in performance. I could not locate the contact number for this vendor as they don't print it on their payment receipts. Why would any vendor not like to give its customers a customer service number to call unless they are expecting return of goods instead of repeat customers

Physically, this item is nearly identical to the Dell branded battery. There are no quality issues at all. It does have the battery meter on the bottom, just like the original one. Since my Dell unit crapped out after 18mo, I can't do any side by side comparisons, but I think the original unit had a bit more capacity. I recall getting 4 hours on my D620 running Fedora Linux (thought that was for maybe the first couple months). This unit is maybe 3-3.5 but again, I haven't really done any scientific tests. It could be that I'm just harder on the Latitude D630 battery now than I was then. Either way, it's a steal at roughly 1/3 the cost of the Dell unit.

Hopes that help you. The next we will introduce the Sony Newest laptop battery: Sony VGP-BPS8 Sony VGP-BPS8A Sony VGP-BPS8B Sony VGP-BPL8 Sony VGP-BPL8A

The 10 factors that can affect Laptop battery using time

eco-laptop
The article first post in http://www.laptops-battery.co.uk/blog/

The process of using notebook computers, some factors that make the battery wear and tear. Even the laptop battery maximum using time less than the standard battery life, it not means the battery have some problem in inherent quality and performance. Notebook battery capacity mainly determine by the size of the marked mAh on battery. The size of the laptop battery MA hours directly related to the using time. Battery using time are also have a great relationship with notebook configurations.

Then we list all the specific factors that can affect the Dell WW116 battery life:

Factor 1: the processor speed - install the the right Intel chipset driver will enable the system to use Intel's Speedstep technology, that can adjust processor speed in application system to extend the battery life.

Factor 2: Reading CD, DVD, CD-RW and hard drive frequently- the CD-ROM copy of the file directly to your hard drive, watch videos, dials and other operations will affect the Latitude D620 Battery life.

Factor 3: the total number of memory- if the system opens a lot of applications will take up a lot of hard disk space to do file-swapping (virtual memory), resulting in frequent hard disk read and write.So increase more memory will increase the battery using time .

Factor 4: Some applications to run automatically in the background, it will increase the CPU load, resulting in reduced Latitude D520 Battery using time - We usually suggest that turn off some background programs in the daily use, only run the necessary applications.

Factor 5: LCD's brightness - the lower the brightness the longer battery using time if possible. You can use keyboard function keys to adjust the LCD brightness .

Factor 6: Power Management and Speed Step settings - Set the different power scheme in the power management will affect Inspiron 1720 Battery using time.

Factors 7: Battery life - the average battery life is one year, the gradual reduction of battery usage time is normal as the using. We also think it is the battery aging time.

Factors 8: For the processor and system equipment deeper applications (such as watching DVD movies and 3D games) will make the Inspiron 1721 Battery using time quickly reduce.

Factors 9: Wireless devices and Bluetooth devices will accelerate Dell XPS M1730 Battery consumption; When do not need wireless, you can use the keyboard function keys to turn off the wireless and Bluetooth to save power.

Factors 10: The environmental temperature - too high or too low ambient temperature will affect battery core activity of chemical substances, thus reducing the battery using time and life. The factors is happend obviously in Sony battery as Sony VGP-BPS8 VGP-BPS9.

Overall, the laptop battery using time is not only determined by capacity mAh, the hardware energy-saving technology is also very important.

Where is Laptop using heat come from

Where is Laptop using heat come from

We are using the notebook for some time. Weoften found that notebook slowly get hot after using for a while, especially the bottom of laptop. The situation occur frequently in Summer. Where is laptop using heat come from?

When the machine overheating, some harm reasult happend: laptop system halted, restart, and even laptop parts burn (espacilly laptop battery). Which laptop part produce such a large amount of heat? Here I will give us a presentation.

As the desktop CPU's power consumption and heat is very large. It can not be used in notebook as Dell WW116 , so mobile processors is specifically designed for notebook. Many notebook CPU processor power consumption are over 20W, particularly in the mobile Pentium 4 processor. Though there are a lot of technology tips make notebook average energy consumption low, but the peak is still very high (more than 30W) when using.  Many of these energy consumed will come into heat dissipation. Therefore we should always check the clearance of xps m1730   battery CPU fan air vents. Make sure there are no stolen goods block the air vents, that cause the heat can not dissipate. If the notebook CUP silicone hardening, we should replace it in time.

First, the XPS M1530   Battery notebook cooling heat is mainly come from the CPU working heat. But CPU heat is not the all. And the early CPU processor heat is not very large. Just use some simple passive cooling method that can satisfy the cooling needs of the machine. That is the heat sink cooling as we usually known. However, as the continuing escalation of CPU processors, while in the Pentium processor century, the processor's cooling is the big problem.

Secondly, the graphics card heat is also a large proportion. Early graphics cards heat is not large, but now a lot of high-end machines such as Inspiron E1505 Battery Inspiron E1705 Battery often configure the ATI Mobility Radeon HD4750 or GeForce GT240M such a good graphics card, so the heat also increase a lot.

Finally, there is some other hot parts, such as memory, hard drives, laptop battery, are also a number of laptop heat source.

How to charge your laptop battery properly? During the the process of notebook using, we need no

How to charge your laptop battery properly?

solarroll-laptop-solar-charger

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.

Dell tips about battery life store charge

Q How long does a Dell laptop battery last? When should I consider replacing mine?
A All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell Latitude D610 Battery  when the run time does not meet your needs.

Q How should I choose between two batteries with different Watt hours (Whr) available on one system?
A Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer Dell Latitude D620 Battery  run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.

Q How long am I able to use my Dell lap on a fully charged Dell U4873 Dell D5318  battery?
A Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.

Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, “Understanding Battery Life in Portable Computers” is available at:

Q How do I charge my Dell GD761 Dell 75uyf battery?
A The battery charges in the lap when the lap is connected to an AC power source via the AC adapter.

Q How long does it take for a Dell lap battery to fully recharge?
A The charge time varies depending on the system. If the system supports ExpressChargeTM , the Dell Inspiron 6000 Battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.

Q What is ExpressChargeTM ?
A For a system advertised as having the ExpressChargeTM feature, the battery typically will have greater than 80% charge after about an hour of charging and fully charge in about 2 hours with the system off.

Q Should I totally discharge, then recharge my Dell lap battery occasionally to make it last longer?
A No, discharging and charging does not increase the life of a Lithium Ion technology Inspiron 630m Battery.

Q Can a Dell lap battery be “overcharged”?
A No, the battery is designed to s using the charger when it reaches full charge.

Q When docked or AC adapter is plugged into a wall outlet, am I using my battery charge?
A No.

Q Does Dell sell external battery chargers for Dell Inspiron 510M battery?
A Dell offers a Datamation battery charger for large institution customers. The charger has 16 charge bays to charge batteries for Latitude D500/D505/D510/D520/D600/D610.
