Battery Talk

When given this question to any user of the laptop or notebook, they will get confused. This happens to me once when someone asks me about the battery of my laptop. As you can see, before replacing the laptop battery is very important to know a little about the field again in the first place. There are several types of laptop batteries that I will share in this post.

The article Via Battery blog

The types of laptop batteries:

1. Alkaline – This is a common battery around, but only a few use laptops and the ruling on alkaline Dell Inspiron 6400 Battery is not rechargeable. You have to shoot once to deflate.

2. Lead Acid – One of the most common uses of this kind is for laptops. It is durable, resistant and rechargeable, but unfortunately the Dell Inspiron 640m Battery is heavy and full of lead: P.

3. Lithium-Ion – The type of Vostro 1510 battery that you want to have for your laptop. The quick-charge effect is good for users moving (no need to wait a while for the battery is fully charged.) It is also environmentally friendly as well.

4. Nickel Cadmium – Ni-Cd is one of the oldest types and improved performance of rechargeable Vostro 1310 battery , but has a serious problem. After prolonged use (several years), the battery will be affected by the dreaded memory effect. This means that the use of battery life deteriorates over time.

5. Nickel Metal Hydride – Ni-MH is considered the successor to the Ni-Cd batteries, but unfortunately, the dreaded memory effect is as bad as well. However, comparison of the Ni-Cd and NiMH batteries, it lasts longer compared to its predecessor.

The chances of using lithium-ion Vostro 1520 battery is 99% (that is if you are using the new breed of laptops:)). Just check the abbreviation says Lion or Li-Ion batteries in laptop battery label. There are still some laptops that use Ni-MH batteries these days and you may want to check with the manufacturer if you can make an update of Ni-MH Li-Ion. The unauthorized use of batteries could lead to dire consequences …. so do be very careful about this. If you have a larger budget you might want to check the SMART batteries. It has a power management circuit and also tells the user which is the current condition of the battery.

The typical end-discharge voltage for nickel-based laptop batteries is 1V/cell. At this voltage threshold of approximately 99% of the energy is used up and the terminal voltage begins to fall off rapidly if the discharge continues. Discharge below the cutoff should be avoided, especially under heavy load.

As the battery cells can not be perfectly controlled, creates a negative voltage potential, known as cell reversal, if the discharge is continuing unchecked. The more cells are connected in series, the greater the number is likely to be reversed cells.

Nickel-cadmium may be some reversals to tolerate the typically amount to approximately 0.2 V,. During this period of time is reversed the polarity of the positive electrode. Such a situation can persist only briefly, because the development of hydrogen at the positive electrode to a positive pressure and leads to a possible gas leak from the cell. If the Sony VGP-BPS2C cell for a prolonged period of Spannungsumpolung is exposed, both polarities are reversed and the cell is electrically short-circuited. Such an error can not be undone.

Some battery analyzers use a secondary discharge (regeneration) by performing a discharge of the battery up to a very low cut-off point. This device will monitor the discharge current in order to ensure that the maximum applicable current during the regeneration phase of a safety limit. If the reversal continues to develop, the discharge would be so small that no damage can occur. That cells are destroyed during the regeneration is only possible if these cells are either weak or old.

When Sony VGP-BPS2A cells are discharged with coefficients that are higher than 1C, the end-loaded or typically lowered to 0.9 V / cell. Thus, the voltage drop is compensated, which results from the internal resistance, consisting of wiring, circuit protection and contact transitions. A lower cut-off leads to better capacity values when the battery is discharged at lower temperatures.

Among all the nickel-cadmium VGP-BPS2 battery chemistries is the least affected by repeated full discharge cycles. Several thousand charge / discharge cycles are possible. Therefore, nickel-cadmium are working so well in tools and portable radios, where they are in constant use. Nickel-metal hydride is less durable in respect to repeated Tiefentladezyklen.

Lithium-ion is typically discharged to 3.0 V / cell. The versions of “spinel” and “Coke” can be discharged to 2.5 V / cell, and thus gain a few extra percentage points. As far as the device requires no special Battery, the devices are built for a cut-off point at 3.0 V / cell.

A discharge below 2.5 V / cell can switch the Sony VGP-BPS8 battery protection circuit that is active, it prevents future load with the normal charger. Such a battery can be saved with the help of the Boost program, which is present on the battery tray by Cadex 7000 Series analyzers.

Some lithium-ion VGP-BPS9 batteries contain a specially deep Spannungsabschaltepunkt, where the battery is put permanently out of service, if the cell voltage below 1.5 V / cell falls. A very strong discharge can lead to formation of a Kupfershunts, which can cause a partial or total short-circuit. The same can happen if the cell has a negative polarity and this situation persists for some time.

The manufacturers of lithium-ion batteries recommend a discharge depth at 80%. Repeated 100% discharge reduces the specific number of charge cycles. It is therefore recommended to charge lithium-ion batteries more often, rather as they were unloaded too deep. A periodic full discharge is needed because lithium-ion batteries are not subjected to the memory effect.

The recommended end-discharge voltage for lead-acid battery is 1.75 V / cell. The discharge does not follow the mostly flat curve of the chemistries of nickel or lithium base. Instead, have lead-acid batteries have a degree of voltage drop curve, with a steep drop toward the end of the discharge.

The VGP-BPS9/B life cycle of sealed lead-acid batteries is a direct dependence on the depth of discharge. The typical number of discharge / charge cycles at 25 ° C depending on the depth of discharge is:

· 150 – 200 cycles with a 100% depth of discharge (full discharge)

· 400 – 500 cycles with a 50% depth of discharge (partial discharge)

• 1,000 or more cycles with a depth of discharge of 30% (low discharge)

The lead-acid Dell laptop battery should not be discharged below 1.75 V / cell. Nor should it be stored in a discharged state. The cells of a non-charged lead-acid battery is sulfated, a circumstance that makes the battery useless if it only a few days are left in this state. You should be concerned that the open Klemmespannung always 2.10 V or more.

We often see the 50$ original Dell laptop battery or Apple battery in Ebay. We are also asked about that : your battery is a original battery or not. You should realize that : the battery with the original Brand logo maybe not the original battery.

According to my 5-6 years market experience of laptop battery industry , http://www.battery4.us share some battery purchase note with you.

1. Now the laptop battery market is confusedly. Many low-cost “original” laptop batteries flooded the market. Most of these batteries are the original renovation battery (using a low-quality cells); the same pack with the original battery, no protection battery quality; Some of it is a true original stock battery, but most of them are produced for a long time (even more than two years).

The battery performance greatly reduced, as we all knows laptop battery is a consumable items, lose the performance even in stock; And there is no real brand new original laptop battery in the market, because battery manufacturers will be asked to produce the detail terms number battery by laptop manufacture, according to the amount of customized. The original laptop battery has an official one-year warranty, the market prices are mostly in the $150-200.

2. We all know, the lowest-cost maintenance approach to repair laptop battery (as Lifebook T4220 battery ) is replace the cells. Note that this is the least, sometimes you may have to replace protection board. A good imported batteries cell such as Sanyo, Sony, Samsung and other brands are 5.0$ or more in the market, high-capacity of 6$. Replaceme a 6-cell battery will takes about 35$ dollars or more.

Therefore, we can estimate the original laptop battery Price: 6 cell + battery protection board + enclosure + test fee + R & D costs + packaging + transportation + labor costs + a series of warranty after-sales and other costs, original laptop battery ex-factory price at least 60$, so You should carefully select these 40-50$ “original” Toshiba laptop battery in the market .

3. The main difference between High-quality and low-quality laptop battery Cells

I make the laptop battery as example to explain the diffenence for everyone. There are three kinds laptop battery in the market as following:

1. An original laptop batteries, good quality, need not any evaluation.
2. The famous brand laptop batteries like http://www.battery4.us, high quality and excellent price (the people’s favorite kind laptop batteries).
3. Waste batteries and “original batteries” gave as a gift when buying laptop, usually only stand 2 hours or less. Because these two kinds batteries capacity failed to reach the nominal capacity of standby time. So it is the worst laptop battery (Dell Inspiron 6000 Battery).
4. The replacement battery between 60$-100$ in the market. The battery can standby for 3-4 hours as original battery. But after used abour 10-12 months. The battery capacity reduced a lot or even scrapped. Although it can achieve the nominal capacity and the same standby time as original battery. But the other properties of the battery such as the battery charge and discharge times, the battery anti-aging properties simply can not up to standard. So it can only use 10-12 months.

Most of the 3-6 warranty months warrany “Original battery” and “OEM Dell XPS M140 Battery ” on the market are made of neutral batteries: It achieve the use of nominal time, but it is difficult to achieve the standard charge and discharge times, battery aging fast, average life between 3-6 months. (so they can only guarantee the battery up to six months).

In the end if you want to buy the high quality cheap price battery, just buy the 1 year warranty battery replacement in http://www.battery4.us/. Do not buy the “6 month or less warranty Original battery” in Ebay. As I know I saw many “original sony VGP-BPS8 VGP-BPS9 battery” in Ebay.

Zinc stranded Laptop battery

Order to prevent the risk of further deterioration of the financial turmoil triggered deep-seated economic problems, the Fed announced an emergency rate cut this week in two 75 basis points, to a certain extent, eased the panic in financial markets filled with emotions, the world’s major stock markets have rebounded fujifilm np-95, after following the oversold Yang received. Despite the panic around the popularity to be a little relaxation, but the overall trend is still Zoudie zinc City Channel, lun 3 weeks straight zinc has dropped, the cumulative drop of 235 U.S. dollars / ton, the lowest point (2160 U.S. dollars / ton) touched the bottom of the support line (Zhou K chart, February 17, 2006 and November 23, 2007 low of connections); Shanghai zinc index fell for two consecutive weeks, the cumulative fall of 1618 yuan / ton, the lowest point (17,776 yuan / ton) are also the formation of the bottom of the support (17.6 thousand yuan / ton in the vicinity) stress test. Overall, zinc City last week, showed significant support will retest of the lows.

For the next week, zinc City, the trend caught on because canon nb-6l of their multiple negative factors, will continue to support the wishes of the performance of retest of the lows. Multiple adverse factors are beyond our focus is: the continuing turmoil in the macroeconomic environment; supply and demand data reproduce the excess pressure; investment funds, the formation of bottom pressure of a high position.

First, while the Fed’s emergency rate cut to a certain extent, to prevent the U.S. economy sliding into recession may fast, but monetary policy was helpless further exacerbated by global inflation. At the same time, investors are still worried that the collapse of the U.S. housing market has exposed the questionable mortgage casio battery , casio np-100 lending standards for the industry, followed by credit cards, auto loans and student loans could be the next troubled industry, which make the financial system and economically difficult.

Secondly, the China Nonferrous Metals Industry Association latest statistics show that in 2007 China’s zinc output of 3.714 million tons, increased 17.8% compared with 2006, the average monthly output of 33 million tons. Although the zinc price suddenly dropped from the primary and secondary smelters cut production starting in November or even stop production when compared, the market is estimated that in 2008 a quarter of the average monthly production will decline to 30 million tons, but the overall situation of the domestic surplus in 2008 to show greater pressure (07-08 zinc futures first annual report are described in detail sony vgp-bpl8 , sony vgp-bpl8a), while in 2008 the domestic regulation and control policy tightening will make the “China factor” strong demand growth in the supply of hard to arrival. Therefore, the excess pressure on zinc price to find strong support for retest of the lows.

Finally, the zinc municipal positions rising, while zinc prices have consistently fallen. This shows that most investment funds to see the empty zinc prices, see the empty pursuit of money and zinc prices will also seek a strong support base. From a technical trend of view, careful test of their ability to support LUN zinc 2000 (I pessimistic about the material in 1800 is expected to form a more powerful support), Shanghai zinc 16,600 yuan / ton (pessimism 15,000 yuan / ton sony vgp-bps9). Operation, I believe that Shanghai more than one-zinc reduction or leave the air rallies admission alone. Operational strategy, risks remain due to shock, short-term operation is appropriate.

China Chips

“The world is flat canon nb-2lh, lithium battery industry chain are mutually beneficial and reciprocal, circular links.”

Live in a global economy, communications zero distance of the “global village” where we have to look at the world, a world vision to seek the cause of lithium.

South lithium creation and development of the forum, no doubt benefited from the South China lithium battery sector, especially the South China several Chinese leader in a global outlook and lithium pioneering spirit. The face of an open world, including South China, including B & K Technology lithium enterprises to actively canon nb-3l search for specificity based on industry marketing and industry connectivity strategy, to making China to explore business development and progress of the Pan-lithium and lithium and the world at the Pan-Electric industries face to face opportunities for exchanges.

To 2006, the first, in 2007 the second session of the South China successfully held the Forum, after lithium, as lithium in South China Forum on first organizer – B & K Technology farther cast their sights higher canon nb-4l, and the South China Lithium forum topics from the “China Lithium electricity, from manufacturing to the creation of “Innovation for the Pan-lithium electric industry’s” new inventions, new technologies, new applications, lithium electrical energy revolution. ” Electrician in 2008, the industry’s first lithium-concussion – the third High Level Forum on South China Lithium (International Year) team elite guests, including B & K’s on the kind invitation of the world’s elite eight-nation lithium technology, China’s lithium battery industry, consumer goods, the use of the field leaders and China’s top manufacturer’s at the helm lithium leader of the majority of China’s electrical industry personnel and even Lithium vision Miao Xiang of China’s electricity sector, the world’s lithium-lithium lap a pan-industry, world-class canon nb-5h exchange platform.

B & K Technology Group, as China’s lithium industry pioneer and one of the leading actor in China’s lithium battery industry, an indispensable role. B & K, founded in the late 20th century technology, the erection of lithium power industry under the guidance of the spirit of the national banner, in nearly a decade of development and production of lithium-powered products, the products involved in used cell phones, Bluetooth, DVD, model aircraft aluminum lithium canon nb-5l batteries and other fields batteries, flexible packaging polymer lithium battery. In recent years, the rapid development in previous years, based on B & K Technology also created a sub-market, all kinds of lithium products, including solid-state polymer lithium battery, miner’s lamp battery, lithium batteries for electric vehicles, power tools such as cylindrical lithium batteries the use of lithium series of new materials, new technologies, products and applications during this period nearly 50 core technology patents, fully demonstrated its lead in the lithium industry, new concepts, research and development of new products, guide the development of the industry and to conquer new markets, a strong field实力. This same time, the B & K technology to good momentum of rapid development, BenQ has won national, provincial, and development of preferential policies for the honor, which will include the second half of 2007 was listed on the Shenzhen municipal enterprises and entrepreneurs plate special fund for the company market development plan in 2008 has laid a solid and important foundation sony vgp-bps8.

There are gaps on the need to have progress, progress will certainly be seeking the next step in the development of science and technology firmly in mind Banke “broad decision to heart, mind determine success or failure.” Banke dare to the development of science and technology the courage to connect China and the world of the pan Lithium-Ion battery industry, as the goal, through the South China Lithium forum as a platform, lifting China’s electricity industry in lithium power lithium sony vgp-bps8a battery industry in China, set policy, and then integrate into the world as a whole lithium battery industry in the wisdom of building our brand in China the world’s lithium, and look forward to more Chinese Pan-lithium enterprises, through this worldwide forum for the South China Li-ion lithium power industry platform, break through the bottleneck, to a world-class market and create a world-class brands leap forward.

“It depends on Yinshan a film to open the window into the river.” Seek a world vision lithium cause of cross-flow sea, a thousand sails compete.

To invite the world’s giant lithium lithium co-China study Chinese companies to test the thickness and width of the core of China, sony vgp-bps8b look forward to standing in the world’s forefront of lithium, which in China is the first time in the history of lithium.

Drink green Laptop battery

A Japanese company canon nb-1lh has introduced a wonderful green rechargeable batteries. The cell shape and no different from ordinary batteries, but the difference is that it is a by “drink” to recharge the battery. The battery inside the material is aluminum and magnesium, they will join the liquid with the chemical reaction, resulting in generation of energy. Therefore, to give this rechargeable battery does not require any equipment, only through a special syringe to add some liquid inside the battery can be, whether it is pure water, fruit juice, even beer, can be used to charge it.

Dell XPS M1530 battery customer ratings

Owerhouse of a battery. Charge lasted far longer than the 6 Cell I had prior. I still liked the look of my computer even though this battery was bigger (More bigger than Dell Inspiron 1520 Battery 9cells battery). The extra weight was not a problem (I am female and not very big.)

It Made my computer (XPS M1530 Laptop) so hot I had to return it and buy the 6 Cell. I could feel the heat off the touch pad and where I place my left hand when typing (where the hard drive is located.)

ConsThis battery is nothing special. Yes it is 9 cells but the poor quality of the battery counteracts the fact that it has 2 extra cells as 9cells latitude D620 battery and latitude D820.

I called tech help who did verify that the battery has more “mass” therefore would be hotter. I was surprised by this because what I had read here had me thinking it would be cooler than the 6 cell. It wasn’t. Too bad it was neat.

In all , this Dell XPS M1530 Battery is more powerful than 6 Cells XPS M1530 battery, also it become more hotter than 6 cells..

15 inch MacBook Pro Battery Tests:

AnandTech takes a look at the new MacBook Pro battery s released at WWDC last week and focuses on the new non-removable battery design. Apple first introduced the non-removable battery into the 17″ Unibody MacBook Pro last fall with mixed reactions from the community. Apple’s reasoning behind making the battery custom and non-removable has been the ability to incorporate a larger battery that will provide even longer battery life. They’ve also argued that most laptop owners do not carry spare batteries.

Anandtech does a good job exploring the technology behind the design:

Apple did some clever work on its own here. Standard lithium ion batteries are made up of cylindrical cells, similar to AA Laptop battery . The problem with these batteries is that they waste a lot of space within a notebook (try cramming a lot of cylinders into a box, you end up with wasted space). This wasted space translates into larger batteries than are necessary, which makes for larger notebooks.

They found the 15″ MacBook Pro battery got an additional 46% of battery capacity with no additional weight. Improvements were dramatic in their benchmark testing:

The new 15″ MacBook Pro battery clocked in at over 8 hours in their light load benchmark. The findings did carry over proportionately in their more intensive tests compared to the older models. Andandtech concludes with a very positive impression of Apple’s latest revision:

Ever since I first looked at the power consumption specs of Nehalem I thought it didn?t make any sense to buy a new, expensive notebook before Arrandale?s launch in Q4 2009/Q1 2010. While performance will definitely increase considerably with Arrandale, Apple just threw a huge wrench in my recommendation. The new MacBook Pro battery is near perfect today. If you need a new laptop now, thanks to its incredible battery life, I have no qualms recommending the new MBP.

It may seem like only yesterday (or a couple of months ago) that Acer was rolling out its very first Timeline Acer laptops battery to much fanfare, but it’s now already turned things around and kicked out a whole new addition to the line-up: the 8000 series. Apparently aimed at both business users and average folk, this one will be available in 13.3-, 14- and 15.6-inch variations, and pack the usual Core 2 Duo or Core 2 Solo ULV processors, 4GB or 8GB of RAM, a 160GB or 500GB hard drive (or even an 80GB Intel X25-M SSD, for those looking to go all out), and either some basic Intel GMA 4500MHD graphics or a ATI’s 4330 dedicated GPU — not to mention some bonuses like a multitouch trackpad and optional 3G (at a later date, it seems). No word on pricing or availability just yet, but it seems safe to bet that at least the entry-level models will be sub-$1000, if the current Timelines are any indication. I wonder if its battery power as BTP-44A3, BTP-58A1, BTP-59A1, BTP-60A1

Well, that didn’t take long. Less than a day after Acer announced the new Timeline 8000 series, the 14-inch AS4810T-8480 has popped up on an Office Depot shelf for $699. It’s not bad for the money — you’re getting a 1.4GHz Core Solo SU3500, 4GB of RAM, a 320GB disk, and eight hours of battery life — but we’d wait to buy until next week, when our tipster says it’ll be on sale for $549. Anyone planning to pick one up with discount laptop battery?
