How to discover the true health of your battery?

Posted on April 9th, 2010 in battery review, digital camera battery, laptop battery | Comments Off

The test of AC conductivity was introduced in 1992 as a new way of measuring the CCA (Cold Cranking Amps = Current cold start) of a car battery. This non-disruptive method has been acclaimed and regarded as a breakthrough and, to a large extent, eliminates the discharge test to measure the performance of the Ibm thinkpad t42 battery . The test only takes a few seconds, the readings are displayed as digital numbers and a message indicating the status of the battery. There is no spark occurs at the terminals of the battery and the instrument does not heat.

But the single frequency AC conductance has its limitations. It does not measure the CSF according to SAE standards and provides an approximation about the power of the Ibm thinkpad r50 series battery can provide energy (output). The figure on how much energy often varies with the state of charge (SOC = State of Charge), and other battery conditions. Sometimes, a good battery fails and one that is defective passes the test but by mistake. But his most important drawback is the inability to perform the reading of the reserve capacity (RC). Despite these shortcomings, the AC conductance has become an accepted standard for predicting the lifetime of the battery and to determine when to replace an old battery before it causes you problems.

Figure 1: Battery with high CCA and reserve capacity of 100%.such as Ibm thinkpad r50e battery. A battery with a CCA rate may be compared to a large open tap that allows a free flow.

What are the main differences between the parameters CCA and RC? A high reading of CCA provides good conductivity of the battery and provides a high capacity / ability to boot. A high CSF is associated with a low internal resistance of the battery. Figure 1 compares high CCA with a large open tap that allows a free flow.

The reserve capacity governs the amount of energy a battery can accumulate. A new Ibm thinkpad r50p battery is indicated by the manufacturer as having a nominal capacity of 100%. When the battery gets older, the reserve capacity drops and eventually it needs to be replaced when the reserve capacity falls below 70%. Reading RC always refers to a fully charged battery, the state of charge (SoC) should have no effect on the measure.

It is possible that a battery provides a good reading of CCA and starts well a vehicle while having a low reserve capacity. But the hp Pavilion DV1000 battery will discharge rapidly if we tried to extract extra energy (eg. For accessories). Figure 2 illustrates such a battery. The so-called “content rocky” which accumulates when the battery ages is permanent and this process is irreversible.

Starting with this battery is good but a withdrawal of additional energy will drain the battery quickly

Windows 7 from Microsoft has problems with the battery

Posted on April 2nd, 2010 in battery review, digital camera battery, laptop battery | Comments Off

Why was not announced at the beginning of everything: the new Windows 7 will not only be comfortable, but also better performance and – especially important for the community Netbook – significantly AccumulatorGentler than his predecessor-XP and Vista. Just beyond the duration of the socket was, however, after the start of the new Operating system been viewed critically. While the News and experience something contradictory had, now has Microcosoft confessed: reportedly because of an error, Windows 7 early “land under” the battery(such as Lenovo thinkpad r61e battery )capacity.

New tool to be responsible

According to the statement from Redmond Windows 7 in a newly, integrated tool for the problems should be responsible. Actually, it should warn the user when the Lenovo thinkpad t61p series battery capacity drops to the point that an automatic switch-off threatens to ensure that data loss can be avoided. Apparently, the little helper but a bit too hasty and warned long before the energy is scarce in the current cell. Windows should therefore urgently to replace the battery or load, although this is still filled properly.

Investigations at Microsoft and the technology partners have shown that the resulting reports from the communication of the operating system with the firmware of the Lenovo thinkpad r61i series battery . Therefore seems the software giant from Redmond is not to be able to solve the problem alone. We work with many Manufacturers together to present a solution, Microsoft said.

Severity of problems vary greatly

The problems of Windows 7 come with the Lenovo thinkpad r61 battery life but not on all devices. Especially users of older Netbooks often report even more staying power than unetr Windows XP, as is the case with an HP laptop also earlier date, the term is abruptly dropped from 2 hours to 30 minutes after the update from Vista to Windows 7 was completed.

Overall, the creation of Microsoft sounds a bit adventurous. Windows 7 that requires fewer resources than the previous Vista seems clear on identical systems makes the new operating system faster impression. But that such deep problems in only one tool and unwarranted warnings are justified in front of empty ibm thinkpad x60 series battery appears, but somewhat unusual. The Windows mobile users is probably left over after all nothing more than to wait to find that the guys at Steve Ballmer in the near future a solution.

Properly charging method for Cell phone battery

Posted on March 31st, 2010 in battery tip, digital camera battery, laptop battery | Comments Off

Meanwhile, almost everyone knows now that a new battery when you first load 10 – 12 hours,like thinkpad x60 series battery , and it can accept full capacity. Since they will be highlighted by each of the purchase on it. Since then, all seem to be united.

Disagree themselves are the people but on the Time prior to the first charge:

  • There are dealers who say, when receiving a new device with battery IMMEDIATELY, the ibm thinkpad x60s battery 10 to 12 convenience store.
  • Others say that the battery would have a residual voltage, ie First unloading, Until the battery is empty and the residual stress is gone. Only then 10 to 12 hours at a load.

Related to the residual voltage is correct, because the sony vgp-bps2c batteries are tested before, and indeed for this purpose also partially loaded. A new battery also holds as a rule depending on the device a few minutes or hours to run. But he should be fully discharged really first?

How can it be now properly recharge a battery?

Here are a few opinions. Discuss with and tell us what you’ve done for experience!

  • Only totally unload – then recharge them. And at least 3x.
    Since most devices probably sign off when the inspiron 6000 battery falls below the allowable discharge voltage is averted the danger of a dangerous Tiefstentladung.
  • Such should be even during operation and forth to happen again, to the so-called “counter-memory effect”.

  • For Ni-MH batteries, it does not matter whether at the beginning of the charging process is completely discharged or not. Ni-MH latitude d830 battery have no memory effect. These batteries are supposed to be on all mobile devices in recent years standard. They should be completely discharged when the charge cycle starts.
  • The Li-Ion batteries have no memory effect and can be recharged at any residual tension.

Nokia’s patent is to recharge batteries with motion

Posted on March 17th, 2010 in battery review, battery specs, digital camera battery, laptop battery | Comments Off

Despite all the technological advances in today’s mobile phones, there are still some properties that the manufacturers may be a target of choice, but so far does not necessarily seem to be reached. This includes, among other things, the problem is that the currently used battery materials to reach the maximum of their reserves through active use of mobile phones for voice calls and sending text messages after a few hours,such as Pavilion ZV5000 Battery . For years, manufacturers are hoping for the big breakthrough in the development departments, which could mean that the devices could be significantly more powerful than before.

The ideal in this respect is well produced, cell phones and smartphones, which can give consumers generally on the availability of a power outlet for recharging. This goal is achieved now conditioned by the first so-called “green” cell phones that work with solar panels and allow for charging of the Pavilion DV1000 Battery using solar power, even where there is no access to the grid. The Finnish manufacturer and leader in the wireless platform for Nokia would be a great step to have succeeded, the consumers new possibilities and freedoms in the mobile phone is designed to provide applications.

Allegedly, the recent media reports in various scientific journals such as the journal The Scientist, suggests that it is in the house of Nokia is no longer just in the early stages of research, but the Group has even been filed in the U.S. a patent application. For several years, the experts of the company are working on alternatives to supply electricity from mobile phone Ibm thinkpad t61 battery . Under the plan, allegedly, load cell phones and other electrical appliances in the future on a technology called “energy harvesting” to. This is why, according to the articles that provide the owners with their movements for a downright automatic loading.

Remain more mobile phone users (by Nokia in the central area of mobile communications), the faster the load on the phone at the end. Jogger strollers might even say, or were, so to speak, are due to human Stechdose for their mobile phones in this way. The approach requires that the heavy parts are mounted inside the phone on rails which in turn have nothing fixed, but flexible. Through so-called piezoelectric crystals, which are compressed on the rails, is in the course of movement of the mobile carrier of electricity to be generated, which in turn is transferred to the Ibm thinkpad t400 battery .

Obvious that this is not necessary for a full charge movement workload can be achieved with an hour of exercise for Ibm thinkpad t40 battery . For experts, however, this environmentally conscious approach – Nokia pursued in addition to this, other ideas that would lead to lower demand for electricity – a first step to meet the one hand, the increasing power requirements of the new powerful smartphones. Above all, the system can, if successful, ensure that the few times it should be above the outlet less closely together. Precise data on the possible implementation of marketable a few days ago a patent was applied for the handset manufacturers still unknown. But the message from an already successful: The market has already given new fodder.

Micro-revolutionary breakthrough in battery technology

Posted on March 16th, 2010 in digital camera battery, laptop battery | Comments Off

Infinite Power Solutions (IPS) of the U.S. private technology companies invented such Thinergy Micro-Energy Cell (THINERGY MEC),its professional name is called solid-state thin-film a1185 battery .

But, at present this is only the ultra-micro-batteries, and used in some special areas, such as it is installed in the inside of cardiac pacemaker . Its power is far from enough to support an ordinary cell phone.

Now the Stamp Size of smallest model THINERGY MEC is square 3 cm, thickness is less than 0.2 mm.

Small but capable THINERGY MEC does not contain any heavy metals or toxic chemicals without the non-liquid or organic polymer electrolyte from aspire 3000 battery , using ultra-thin and highly flexible to package.

Lightweight, stable nature can make it deeply embedded and laminated to the printed circuit board or other materials.for the computer alone, if each disk, the chip is embedded in it, it’s apparent to be easy for the burden on the power of many.

  • Magic function
  • Although appearance of THINERGY MEC is unique , but the functionality is very strong.

    Conventional batteries are broadly divided into two types: rechargeable batteries and disposable batteries. Generally for its long life and a repetition rate high esteem ,the rechargeable TravelMate 2440 series battery is esteemed by the majority of electronics manufacturers, while the disposable batteries are based on the characteristics of high power.

    THINERGY MEC, who also has the above two features. It can be charged, and can also maintain a high energy.

    THINERGY MEC charge can be completed within ten minutes, while the leakage rate is a low loss of only 1% per year, life is more than a decade. On the current test results, if the battery is 100% discharged, THINERGY MEC rechargeable can be charged for 10000 times, you can save 80% capacity. By contrast, the existing battery is 50% discharged ,the thinkpad x60 battery life is 1000 times .

    for charging more times, THINERGY MEC is not enough to become a revolutionary product. Amazingly, it can not be charged , and permanent used .The reason is in addition to the ordinary charge form – beyond the power plug, THINERGY MEC can also convert light, RF radio frequency, power, thermal energy into electrical energy to storage.

    In other words, if the energy is combined with the environment, THINERGY MEC can provide a permanent power, and achieve more than a decade of maintenance-free operation.

  • Micro-electronic cardiac
  • However, at present, THINERGY MEC has not yet can be used in everyday consumer electronics field.

    At present there are four kinds of THINERGY MEC, the main difference is the power difference. the available now is the power of three large, but the maximum capacity of TravelMate 2440 battery is 2.5 mAh, however. The ordinary generating capacity is 5, battery 1000 mAh or more. In other words, THINERGY MEC’is not designed for “light bulb” service.

    However, due to size, charge and discharge frequency, self-produced electricity and other characteristics, THINERGY MEC is very suitable for useing in wireless sensor nodes, plant into the type of medical equipment, military equipment, such as micro-miniature electronic products, but also can be used as back-up power supply chip selection.

    I hope that one day, this battery can not only embedded in people’s heart pacemaker, but are also able to be used in household appliances such as cookers and hair dryers.

How to purchase and use Battery

Posted on February 24th, 2010 in digital camera battery, laptop battery | Comments Off

How to Choose Battery

  1. Choose the “National Inspection-free”, ” famous brand” (such as Samsung sb-l160 )logo and the local brand-name batteries battery products, the quality of these products have a certain protection.
  2. According to the requirements of electrical appliances, select the appropriate cell types and specifications of size and power apparatus ,and according to the size and characteristics of power, purchase equipment for electricity battery.
  3. Pay attention to checking the battery production date and shelf life, buy the recent production of the battery (for one thing ,the new Nikon en-el7 battery), the new battery have good performance.
  4. Pay attention to checking the appearance of the battery,should buy packaged refined appearance neat, clean, no signs of battery leakage.
  5. Pay attention to the battery symbol, the battery should be marked with the production mark the make, battery polarity, the battery model, nominal voltage, trademarks, etc.; sales package (such as two heat-shrinkable, or four heat-shrinkable, or hang tag card ) It should have the Chinese factory, manufacturing date and shelf-life or shelf life of the deadline marked the implementation of the standard number. Purchase of alkaline zinc-manganese battery ALKALINE, or whether one should look at models LR words.
  6. Due to mercury batteries harmful to the environment, in order to protect the environment, the purchaser should select the label marked “mercury-free”, “0% mercury,” and “no added mercury” indication of battery,take the Nikon en-el3e for example .

Should pay attention to the use of batteries :

  1. Electrical appliances and battery contacts should be clean, if necessary, wipe with a damp cloth until the dry loaded correctly marked by polarity. When loading the battery to see for the polarity ( “+” and “-”) to install an extremely important ,and should be the specification requires the installation of electrical appliances with the use of the recommended batteries; do not follow instructions required will lead to equipment failure, damage to electrical appliances and / or battery.
  2. Should also replace all batteries in a battery, do not mix old and new batteries together; the same model but a different type or brand of battery electrochemistry do not mix, such as Canon nb-4l and Canon nb-3l , and otherwise it would be a set of batteries in use in some of the battery over-discharge state, thereby increasing the possibility of leakage.
  3. Can not heat for a one-time or charge the battery for recycling, or they may explode.
  4. Can not make the battery short-circuit to avoid battery leakage and resulting damage to the heat generated by insulated packaging.
  5. Electrical appliances should be removed from the battery for a long time without using , the power should be closed after using to avoid the battery going on to discharge its internal chemical reaction took place which led to leakage of the negative.
  6. Used batteries for sony vgp-bps2a should not arbitrarily discarded, as far as possible separated from other garbage running.

The reason of mobile phone battery explosion

Posted on February 21st, 2010 in digital camera battery, laptop battery | Comments Off

Why do mobile phone battery for Nikon en-el8 explode? The most fundamental reason is that consumers have used the lack of security of fake and shoddy battery. Cells belong to a certain dangerous chemical industrial products, if you encounter over-voltage, over-charge batteries, etc. will be fever, does not meet the safety standards of the batteries is very likely to cause fire explosion. The fake batteries usually cheap, failed to meet the national standard batteries and materials, and some even failed to protect the circuit board or a protection circuit cold solder joint or aging, and some even make use of recycled raw material for production of waste Jvc bn-vm200 batteries , the danger is self-evident.

Expert introduce how to safely use mobile phone:

A manufacturer who told this writer that the battery safety problems exist not only mobile phones. At present, all kinds of batteries (such as Fujifilm np-120 )has become a modern life, basic equipment, mobile phones, portable computers, portable devices can not do without the battery, if the use of low-quality batteries or used improperly, these batteries have the possibility of an explosion.

At present mobile phone mostly used lithium ,Samsung sb-l320 batteries, Generally, there are three reasons of the battery explosion.

  1. The battery itself, the reasons. Since the apple a1022 of internal defects, the battery does not charge itself does not discharge the case of an explosion.
  2. The long-term overcharge batteries. Lithium batteries might generate substantial transient discharge currents in a special temperature, humidity and poor contact, etc. or the environment , triggering spontaneous combustion or explosion.
  3. The battery for Samsung sb-l160 short-circuit. This is less likely. In addition, consumers put mobile on the high temperature or next to flammable materials ,it may also trigger an explosion.

Zinc stranded

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.

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.
