My shoppingg experience buying Dell inspieon E1505 accessories

Two month ago, my Dell E1505 battery failed after its 1 year warranty. So I should buy a new one for my coming holiday in Hawaii. Now I will never shopping in Ebay or Amazon. As you know you buy someone there, and no guarantee of the product, also the money refund is impossible. And you can not cancel the order. So I decide use my paypal to buy the Dell inspiron E1505 battery.

I searched the Inspiron E1505 Battery in google and found search resault. Then I click some of them, after long time comparison I order a battery from http://www.discount-laptopbattery.com as Its price and 30 days money back and one year quality warranty. After 7days I recevied the battery and below is my battery using experience:

I was getting three red flashes and one green flash continuously on the battery light on the lower right side of the lid which according to the manual means defective battery which turned out to be true. I trashed the cheap Latitude D820 Battery (which I noticed was rated at 5200 ma vs the rating of 7200 on the Amazon battery)because I did not save the receipt. I am thrilled with this battery which is giving me about 3 hours before needing a charge, and charges to 100% overnight with no problem.

It works well with my 1505. I got 4 + hours out of this per charge. Saw some other people having problem with recognizing the batteries. When I was doing research for purchasing a replacement Latitude D620 Battery, I came across a lot of discussions online about Dell laptop not recognizing batteries. I wonder if that is a common issue with Dell. Luckily, mine has no problem. Everything is good. As long as it can last 1 year or so, It would be worth the money spent.

Owned for 5+ months. I am pleased with this Latitude D830 Battery I was glad to find it at a price much lower than Dell was selling it. It was a great buy. Product came right when I needed it and has worked great for me! Good battery life.

In all The battery is compatible and works well with the Vostro 1000. Instructions are confusing. I simply installed and followed good battery practices – completely charged the battery, completely drained the battery, then repeated.

In the end I saw some New batteries in this online shopping are in 35% price discount as the Merry Christams Day coming. I list them below with the brands:

Dell inspiron 1520 battery review

Dell inspiron 1520 battery review

The update of Dell’s popular inspiron E1505 battery, the Inspiron 1520 has generated a lot of interest in the notebook community. It features a complete design update, the new Intel Santa Rosa platform, and the best graphics card Dell has ever offered in a laptop of this size.

The battery Inspiron 1520 is compatible with Dell notebooks including the Inspiron 1520, and replace the Dell battery code : 312-0518, 312-0589, 312-0590, 312-0594, 451-10477, fp282, gk479, nr239. This product comes with 1 year limited warranty.

The Dell inspiron 1520 battery Specs :

Battery Type: LI-ION
Technology : 6-cell lithium ion
Capacity: 49WH
Dimension: 201.2*47.1*20.3mm
Weight: 325g
Manufacturer Part# : FP282
Also work with : Dell Inspiron 1520 battery , Dell Inspiron 1521 battery , Dell Inspiron 1720 battery , Dell Inspiron 1721 battery , Dell Vostro 1500 battery , Dell Vostro 1700 battery

Effective laptop battery life under heavy processor load with high performance settings appears to be about three hours with the 9-cell battery. You could probably extend that to four hours or more by disabling wireless, turning down screen brightness, and using less intensive applications. The 9-cell battery does extend about 3/4” from the back of the laptop, but this does not seem especially noticeable given the already larger size of the notebook.

Customer Ratings :

So every year or so I’m expected to shell out ~$150 for a new inspiron 1520 battery? Mine stopped working shortly after one year. When I plug it in vista says “Battery 0%, NOT CHARGING” now, so I cannot use the laptop unless I am somewhere where I can plug it in. Great!
Not to mention it took almost 3 months for Dell to even ship this thing to me in the first place. I’ve been buying Dell computers for 10 years but not anymore

I used to have the 9-cell Dell 1520 battery before it had to be replaced, and the 6-cell doesn’t compare. The 9-cell lasted a lot longer without having to be recharged. Overall the battery is fair considering that it is the only one you can buy for the Inspiron 1520. It will last you for about a year, then be ready to buy a new one.

9Cell 80Whr Lithium Dell Latitude D830 Battery

9Cell 80Whr Lithium Dell Latitude D830 Battery

The Dell Latitude D830 is the successor to the Latitude D820 Battery, a mid sized business notebook with a 15.4″ screen and the new Santa Rosa platform. Weighing in at nearly six pounds it tips the scales at the upper end of the thin-and-light category.

Dell Latitude D830 battery specs:
Technology : 9-cell lithium ion
Capacity : 80 Wh
Manufacturer Part# : MM165
Dell Part# : 312-0538
Work With : Latitude D820 battery, Precision Mobile M4300, Dell Latitude D531

Dell Latitude D830 Battery is a Dell normal battery. You can power your laptop with this 9-Cell Lithium-Ion Primary Battery from Dell. With a capacity of up to 85 WHr Latitude D830 battery. This product comes with 1 year warranty. In my opinion it always can work about 1 year and 1 weeks long, just out of its quality warranty.

I did a simple test to emulate light use of the laptop under Dell D830 battery power. I turned the screen down to half brightness and let windows media player play music at a relatively low volume. This test was also done under the default Vista setup, prior to the installation of ForceWare drivers.
The 9-cell primary on its own reached 10% in a bit under three hours. Together with the media bay battery it reached 10% in just over four and a half hours.

Customer reviews:

Review:For the first year, the product will work well. Shortly thereafter, the Dell laptop battery life will not slowly decrease. Immediately you will notice a drastic fall in battery life to around five minutes. For battery performance, this is unacceptable. The warranty is only one year for a reason. Unless you plan to buy batteries annually (or thereabouts) i suggest buying another type of laptop. In all the Latitude D830 battery is "Easy to swap out – works like a champs".

Dell Laptop battery maintenance guide

Dell Laptop battery maintenance guide

Battery is the consumables, with a limited life expectancy, most manufacturers warranty for the notebook battery time ranging from three months to a year, Dell is to follow industry standards to provide a limited warranty for one year. For batteries, use the correct and proper storage, can significantly extend the Dell E1705 battery life of notebook computers.

First, the battery useing must follow some attention points.

1. When you use laptop with external power, you dont need to take out the battery.

1. There is a chip to prevent over-charging in the mainboard. When the rechargeable battery power to 100% state of charge, the charge control chips (FET) will stop charging the battery. We do not have to worry about damage to the battery.
2. Connect the 851UY 75UYF 1K500 battery to avoid loss of BIOS information.
3. To prevent a sudden loss of power break.

2. To prevent exposure to prevent damp to prevent the erosion of liquid chemicals, batteries to avoid contact with metal objects, such as exposure to short-circuit occurrence.

3. Long-term do not use notebooks, how to store the laptop battery?

We will have a period of time not to use the notebook, the 851uy 75uyf 1k500 battery is fully charged to preserve, or to be released after save electricity?

Put long-term preservation of photoelectric batteries will lose their activity and even lead to the control circuit protection self-locking and can not re-use, full of power will bring about long-term preservation of the safety problems, the best method is to save electricity use to 40 or so and then stored in cool dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to come up with to use a battery, the battery can ensure a good state of preservation, but also does not allow the loss of electricity damage to the battery completely.

How can I exam the Dell battery power? (For example in cell D610 battery)

Remove the battery, press the Macbook Pro battery power signs, we can see the situation of the five battery status lights. For two bright, representing 40% of the electricity. Electricity on behalf of the entire light is sufficient, if the 135-light, that damage the battery.

Second, how to extend as much as possible the work of laptop battery time?

1. To reduce the screen brightness. How to adjust the brightness of the use of laptop batteries, boot by F2, into the BIOS to adjust the Brightness of Video. Or fn + down / up key combination to adjust the brightness quickly.
2. Open the CPU speedstep feature, you can greatly extend the working hours of latitude x300 battery; Cpu’s speedstep feature is enabled by default BIOS of. When using batteries, cpu will automatically down-use, in order to achieve energy-saving purpose. If not enabled, please start by F2, into the BIOS found in Performance, for the Speedstep Enable setting Enabled. (An earlier version of BIOS is the Alt + P to the sixth page, modify intel speedstep)
3. make the best use of standby, sleep and other functions. When a longer period of time without a computer, allowing notebook standby or hibernation, both to save power and extend the life of the computer. (Tips: Please confirm the successful installation of graphics drivers, power management options can be set up.)
   WINDOWS in the process of power management settings, we generally can be set to “portable / laptop” (Portable / Laptop).
   At the same time suggest that you will use the powerbook G4 battery when the wait time to close the monitor is set to 5 minutes, so when we do not operate within a certain period of time the notebook, it will direct the state of black screen, so other than the screen saver to run more power.
4. when using the battery as much as possible the closure of wireless, Bluetooth and infrared ports. At the same time to remove without the use of peripherals and to avoid the opening of a large 3D program, games and so on, in order to reduce unnecessary battery consumption.

Of course, on the controversy over the use of batteries, there are divergent views have any objection if we can http://bbs.dell.com.cn forum to ask questions, let us discuss how to maintain the battery.

Dell Inspiron E1705 use experience

Dell Inspiron E1705 use experience

Dell launched its new company, one based on Intel’s latest dual-core processors, New notebook Inspiron e1705 battery, the sensation caused by the outside world. In fact, the introduction of Dell notebook computers is not the big events, but this notebook based on Intel’s dual-core processors, let us look after.

Dell launched its new company, one based on Intel’s latest dual-core processors, New notebook Inspiron e1705, the sensation caused by the outside world. In fact, the introduction of Dell notebook computers is not the big events, but this notebook based on Intel’s dual-core processors, let us look. The Dell Inspiron e1705 introduced the use of wide-screen design, which in the Dell e1705 battery model “e” on behalf of the “entertainment”, as its name suggests, this laptop is aimed at the entertainment to the. According to a Dell spokesman said the company, which integrates a large number of notebook computers, and multimedia features available, and use of dual-core processor, with a number of slots, high-end graphics card (nVidia GeForce Go 7800). From these configurations, we is not hard to see, Inspiron e1705 for shaping the image of entertainment notebook PCs, is under the feet of the capital.

Dell e1705 17-inch notebook

In fact, the introduction of Dell’s new notebook computers and the introduction of the Inspiron 9400 battery had great similarities, in particular, both of which are based on Intel dual-core processor. But another big difference between the two, for example, e1705 available Windows Media Center Edition, and it can be treated as an operating system; e1705 also provides a external USB TV tuner options.

Well, we can not talk about the channels of Dell notebook computers and selling price, and we look at the e1705 or focus on a number of important configuration and performance.

Overall design of e1705

In the overall design, e1705 has carried on the Inspiron 9300 battery notebook computer design, but also based on the Inspiron 9300 battery a great breakthrough. e1705 to the overall silver-gray color-based, with the surrounding white, which makes the whole computer looks very simple and clear, people saw there was a desire to want to buy. On the tone in this area, e1705 and HP are in sharp contrast dv8000z (which the same notebook computer for 17-inch widescreen). the overall design dv8000z very crowded, yesterday I looked, just like all the show full of lights and buttons, not only so, dv8000z tune used is black, and black from start to finish. Personally, I think, e1705 in terms of the design is completely through. But I do not think the e1705 is the best design, for example, production TravelMat Acer notebook computers and Apple’s MacBook Pro notebook computers, I think that their design concept a notch higher than the e1705 , but that does not mean that The design on the e1705 will not do, I just feel that compared the two, e1705 just seemed to be somewhat inferior.

In this display, the Dell has provided two options, which means consumers can choose from with a WXGA + (10 cutting the screen known as the WXGA +)-style display, but also can choose to display with UXGA TrueLife. The e1705 I tested with the UXGA TrueLife screen (also the inspiron 6000 battery) is, TrueLife screen as a result of making more light, so much the favorite of consumers. It is because of this, many computer manufacturers in their products equipped with this display, for example, Xbrite Sony laptops, HP’s BrightView notebook computers, as well as Fujitsu’s notebook computers CrystalView. Not only that, but this glossy design by those who like to entertainment-oriented notebooks in favor of the customer base, mainly because it can smooth the design to provide better color contrast, as well as very good to deal with black-and-white brightness of the difference between, if consumers want to watch movies on the laptop, or browser, then a large number of photographs U4873 D5318, TrueLife display is the best option. However, UXGA resolution also means that the displayed text and icons will be very small, which is relatively weak for those with visual, or do not like the small text of consumers, it is necessary to consider carefully whether to choose UXGA display screen. On the contrary, it rather, WXGA resolution can provide the text, so easy to read data and view the page.

Dell Inspiron E1705 Processor and Performance

As a good product, the processor is critical. Therefore, Dell uses Intel’s latest dual-core 2.0GHz processor, which means that e1705 can run several tasks in parallel. Test, I also found that even the anti-virus software to scan for viruses, but also play CD, open the Word and the Outlook window, as well as the HTML Editor and Visual Studio (a code development tool), e1705 running speed and no corresponding slow down U4873 D5318, which made me very surprised, because to run such a large number of procedures , which do not slow down the speed of it is not possible, but Dell has done.

Dell e1705 laptop top design

I think the e1705 is not successful designs in this area, in fact, Dell e1705 in order to allow more people, but also to a large extent reinforced its solid performance as Dell B130 battery, for example, e1705 on the casing and keyboard design is very strong, especially in the design of folding seam Office, Dell is a painstaking, because Dell has been the thousands of open / close up of the test to the e1705 is not out of line, which say it is hardly surprising that Dell e1705 for the “Road Ready”, I personally think that the reason why call Dell e1705, probably because the laptop has been such a good design is good for you G5266 HD438 KD186, and only waiting for the majority of the consumers to buy, and somewhat similar to everything said wind.

In addition, the Dell e1705 is also a free-falling and high-temperature tests, all of these tests are a proof of the e1705 is a good machine.

In order to make a more solid performance e1705 Dell e1705 use in a magnesium alloy material design (mainly in the notebook computer at the bottom of the shell and use of this material), this design, in order to provide greater protection e1705, which also means that the shell can provide a very good screen protection. If we do not believe that we may as well be a test case on hand in the press, usually the case, we will have a folding screen to see the waves appear, but the e1705 screen, we are unable to find any such folding wave. At the bottom of the notebook computer using this magnesium alloy timber design, its protective effect is obvious as G5266 HD438 KD186, think about it, if the laptop drops down, or have an enormous impact, such protection is obvious (in particular users e1705 with the mission to go out or go out of office hours). Not only that, e1705 hard drive also features a shock absorber design, this design is to prevent the computer after the break, to protect the data in the hard disk are not disturbed, played the role of data protection.

In order to strengthen the Dell e1705’s durability, especially in the department’s application of the folding seam steel design, all-around ring to plastic boxes (mainly will have a stabilizing effect). When we hold hands when the e1705 is feeling less than its displays of any abnormal instability.

In general, e1705 of this design I was very impressed, I believe that this design concept will be in the near future will replace the desktop machine. Dell Inspiron e1705 and inspiron B130 battery as a high-end entertainment models, and its impact on the people there will once again select the home entertainment computer thinking, compared to bulky, complicated to connect desktop computers, high-end entertainment notebook has its inherent advantages. With the prices of factors such as changes in attitudes, there will be more and more people choose high-end entertainment notebook such as the first choice for home entertainment.

Customer Reviews

1) There is a rediculous amount of internal circuitry built into battery for voltage and current monitoring during the charge / discharge cycle and for thermal protection as well as LED indicators to show battery health as I do on my pa3465u-1brs PA3451U-1BRS. On tear down of the older battery that this new one replaced, I counted 14 large scale surface mount IC’s and many small ones on two circuit boards.
2) The batteries are spot welded to the connection straps which makes for a strong anti shock connection.
3) Trying to repair the old 4 cell battery… I found that, taking time and the cost of one cell into account, it was cheaper to purchase the new 6 cell battery pack than to try and repair the old one.
Cons1)individual Dell D610 battery cells are extremely difficult to find (in the US) and expensive. These are industrial type battery cells.
2) Unless you have a hot air SMT desoldering station there are no serviceable parts in the battery pack. My recomendation is don’t bother taking one apart… it is a waste of time (and could be dangerous also).

ReviewI purchased this 6 cell battery for my fathers Latitude D600. It was shipped very quickly to the house and my father has been very haapy with his notebook since the new battery was installed. After an initial charge I turned on the D600 and let the system settle down ( hard drive and cd stop spinning ). After about a 5 minute wait I checked the battery level monitor and it showed a 14 hour charge remaining, this happened to my pa3465u-1brs PA3451U-1BRS. (keep in mind that this number can change ALOT when you access the hard drive or optical drive). I am pretty happy with the results.

Normal performance is restored. Too bad it has to cost so much to get there. In general, I’ve had good luck with Dell batteries so long as you condition them properly (run them all the way down before charging, etc.) and battery life is greatly improved over the last few years as vgp-bps2c vgp-bps2a, but the technology is still lagging behind the rest of the machine.

Dell should really start a policy of providing a means to return the old battery in the shipping box for the replacement to allow recycling. No telling how many of the old units wind up dumped into the environment simply because it’s such a pain to get them to a place that recycles. Dell offeres recycling on old PC’s, why not batteries too?

• Battery Code : c1295 6y270 3r305

The Dell Inspiron 510m is a little bit different from Inspiron series of the past, the Inspiron 510m battery is market for small business users and designers. Up from the design and characteristics the inspiron 510m may more like Inspiron 5000 series, but it still have some important changes. The use of integrated graphics chip is the most significant changes of Inspiron 510m battery Series as Inspiron 5000.

But since the general view that business users will not use the notebook to play games, so graphics chips change and users will not be a focus obef debate. More importantly, the changes should be three times the bandwidth of its built-in 802.11 WiFi wireless card, you can use it 802.11a/b/g wireless network connection. This means that with this Inspiron 510m latitude d610 battery, you can connect wireless Internet access all over the world. This is a good news for the people who often necessarily carry books around the staff. In addition to WiFi wireless card, this Inspiron 510m is also a standard Bluetooth interface, as long as you have a Bluetooth cell phone support, you can send and receive an email anywhere.

Although this Inspiron 510m with Pentium M 1.7GHz processor, but there is no Intel Centrino paste (Centrino) label, it is because its wireless chip is not Intel, but Broadcom produced. Another regret is that Inspiron 510m is only 256MB of PC2100 DDR SDRAM memory as latitude D600 battery, although you can slowly upgrade their own future, the cost to upgrade is much cheaper than buy from Dell, but the two memory slots are filled. The laptop have a big enough hard drive, a 60GB, standard DVD / CD-RW combo drive which is the mainstream of the current configuration.

1400×1050 resolution is very common in many 15-inch notebook screen , and Inspiron 510m course this is no exception. We mentioned above, the laptop is the use of integrated graphics chips, so it is not ideal when running 3D applications, but running Windows system and DVD playback with 3R505 is not a problem . Intel Extreme integrated graphics chip to allow the largest share 64MB of system memory, but performance of the system maybe solow if you show too much memory.

The most problem of Inspiron 510m is the inspiron 510m battery capacity. Inspiron 510m battery only can last 2 hours 28 minutes. Although this and the Dell battery standard work time, but I think that for business users that is too short. Commercial users for 2 hours 28 minutes is also too short. In order to solve the problem of Dell D610 battery, Dell provides a choice of a second C1295 battery. Dell said this back-up battery to provide them with additional two hours of electricity.

Conclusion:
From its characteristics, performance and battery life, the Inspiron 510m is really a hodgepodge of laptop. Its distinctive characteristics, a moderate level of performance (although within plus 256M Kept on will increase performance), short laptop battery life. However, it is not expensive relative to the prices, or be a rugged business notebook.

Dell battery User’s Guide: Checking the Battery Charge

Dell battery User’s Guide: Checking the Battery Charge

The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and icon, the XPS m140 battery charge gauge, and the low-battery warning provide information on the battery charge.

Dell? QuickSet Battery Meter

If Dell QuickSet is installed, press

to display the QuickSet Battery Meter. The inspiron e1705 Battery Meter displays status, battery health, charge level, and charge completion time for the battery in your computer.

Microsoft? Windows? Power Meter

The Windows Power Meter indicates the remaining 40D battery grip charge. To check the Power Meter, double-click the icon on the taskbar.

If the computer is connected to an electrical outlet, a icon appears.

Charge Gauge

Before you insert a DV1000 battery, press the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery has no charge.

Health Gauge

The battery operating time is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, DV2000 battery lose some charge capacity, or battery health. To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery. See Specifications for more information about the battery operating time.

NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then connect the computer to an electrical outlet, or install a second battery in the media bay. If the battery runs completely out of power, hibernate mode begins automatically.

A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The computer beeps once, indicating that minimal battery operating time remains. During that time, the speaker beeps periodically. If two DV4000 batteries are installed, the low-battery warning means that the combined charge of both batteries is approximately 90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low level. For more information about low-battery alarms, see Configuring Power Management Settings.

Dell 4 cells 2200mAh inspiron Mini 9 battery test

Last night I ran a quick test on how long my new Dell Inspiron Mini 9’s battery would last under “normal netbook workload”.

This is the Dell inspiron Mini 9 battery Detail info:

14.8V 4Cells 32.4WAh Li-ion battery (As HP Pavilion DV4 battery, Pavilion DV5 battery, Pavilion DV7 battery, Pavilion DV3000 battery)

Dell inspiron Mini 9 batetry Test Details:

• OS: Gentoo Linux (what else? )
• Running programs: KDE 4, Konqueror, Thunderbird (fetching mail via IMAPS every 5 minutes)

• Display set to lowest brightness level, screensaver / standby / etc. deactivated so that it was switched on all the time.

Dell inspiron Mini 9 batetry Test Data capturing:

The ‘remaining capacity’ value from /proc/acpi/battery/BAT1/state and a timestamp were written to a file every minute:

#!/bin/bash  LOG="/home/pn/batterylog"  echo "Battery log, started $(date)" >$LOG  while ((1))  

do    TIME=$(date "+%s")    

REMAINING=$(grep "remaining capacity" /proc/acpi/battery/BAT1/state | cut -b 26- | cut -d' ' -f1)  

  echo "$TIME $REMAINING" >> $LOG    sync    sleep 60  done

Dell inspiron Mini 9 batetry Test Results:

The Inspiron Mini 9 battery lasted a little longer than 4 hours and 50 minutes which means approx. 6.7 watts average power consumption while browsing the web over WLAN.

This time I decided to use OpenOffice Calc to create the graph -
