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?

Dell inspiron 510M review

The Inspiron 510M Specs

• Chipset manufacturer & model : Intel i855GM
• System memory (quantity & type) : 512MB PC2700 DDR SDRAM
• Memory slots (occupied/free) : 1 1
• Max memory in current configuration/supported : 768MB/1GB

• 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.

Canon BG-E3 DSLR Battery Grip review

After sold out the EF-s 18-55mm, I intend to buy a tripod, but finally meet someone sell BG-E3, the price is reasonable, so I put away the tripod temporarily to seize this rare opportunity.

Most of the person can not understand that why want to buy a battery grip? The price is expensive, and seems not valuable, I also hesitate for a long time before I buy it. After I use it, I found the battery grip is really very useful.Now there are many battery grips in the market as Canon BG-E3 BG-E5 BG-E2N, Nikon MB-D40 MB-D80 MB-D200, Sony VG-B30AM and So on.

Compared with BG-E3 350D, the machine performance improvement can be listed as follows:

• Add the vertical photo function. It is quite suit for me, as I prefer to take photo vertically, previously, I have to hold up my hand to take photo, it is not only tried but also difficult to hold stable, the success rate is low, and arm is sore, if the camera lens is heavy, it Is easy to be disabled.
• Increase the machine body hand feel. As the body design is very small, little finger has no place to put, it is often emerge un-stable situation, if with a grip, it will be more stable.
• Enhance the power. 350d is quite power saving, according to my own using experience, it mainly can take around 400pcs photos, and the battery will show low power when it remains 20% power, but if the photo capacity is quite large and without charger, it is bad, BG-E3 can use 2pcs NB-2LH battery to supply power, the duration ability enhanced a lot, besides, if it is still not enough, then you can use 6pcs AA battery to take photo to solve the power shortage problem.
• Enhance the brightness degree. It is due to your own psychological effect, after install the battery grip, it is brighter, but also heavy, the machine body and camera lens weight increase to 1200g, it seems like that I have to take more exercises, as the good photo not only need excellent technique but only healthy body. ===================================BG-E3======================================

It to a lot of people compare Apple Macbook Air Apple Macbook Air as “the ultimate thin and light” and the ThinkPad X300 is a “no compromise light” here refers to the uncompromising performance, the existence of Apple Macbook Air interface less than , non-standard optical disk drive, memory card there, and many other battery change not regret, and the ThinkPad X300 is more comprehensive.

Light, is the beginning of thin ThinkPad X300 notebook to get the first impression, as is currently the lightest full-featured notebook 13 inches, really deserves. Whole transmission is still the appearance of the “black” appearance of the classic, although the machine has been monotonous black as main color, but it gives the feeling of losing fashion. Its powerful battery is litium battery as VGP-BPS8 VGP-BPS9 VGP-BPS11 VGP-BPS13. The reason why such a thin and light ThinkPad X300 with its use of the material body has a great relationship, X300 using CFRP carbon fiber and glass fiber GFRP as top and bottom of the body material, to ensure a solid body of good control at the same time weight machine.

Thinkpad X300 battery using locking design, unlock the front left is located in the fuselage, one-handed opening and closing of the notebook some difficulties, but the benefits of this design is the security of the notebook have a good guarantee. Of course, there are less than each notebook, I use the X300 for some time, found that the shaft resistance of a small notebook, so I do not know the design of the notebook, or more than the number of opening and closing of cause; In addition, the skin texture of the matte notebook region, if the user the situation in this touching and humid, it is easy to leave a mark, but it is very difficult to remove.

Thinkpad X300 interior design, in the whole extension of the ThinkPad is still the IBM traditional style, in the middle of the screen set up above the 1.3 million-pixel camera, the camera lights next to the keyboard, user-friendly to use in the dark. In the look down in the notebook inside of the two axes are the logo and the Lenovo logo X300.

Relatively rich interface X300 is a big selling point, many people give up Apple Macbook Air and X300 choose one of the major reasons is because this point. Although the X300 compared to the ordinary 13-inch notebook interface or worse, but has been used to meet the day-to-day. The following is a notebook specific distribution of the interface.

In fact, the whole performance of X300 can only say that it is ordinary, Core 2 Duo L7100 processor frequency of only 1.2GHz as thinkpad X200 battery, but the application of the ordinary day-to-day, or enough. In fact, the hardware configuration of the X300’s biggest bright spot is the hard drive is equipped with, X300 uses SSD solid state hard drive, SSD solid state drive uses NAND flash memory, hard drive not have to worry about the collision of data loss, which greatly raised the hard disk data security.

Overall, this notebook is remarkable, 13-inch thin frame, 1.33 kilograms of whole weight, the excellent performance of the hard drive, LED screen, said to be worthy of the ThinkPad family of a milestone for inspiron 6000. But there are also many places with some regret that the general processor performance, interface, or a little weak, especially the price of the current wetlands, or some to be prohibitive. The X300 is currently priced at 24,999 yuan, more suitable for high-end business users, especially for a portable notebook and endurance than the value of this part of users.
