Advanced Battery Analyzers

How are batteries checked and serviced? This article describes the advancements of the modern battery analyzer and explains how these instruments are used in the industry. While organizations such as public safety have been using battery analyzers for the last two decades to restore and prolong nickel-cadmium batteries, analyzers have made their way also into the cell phone, portable computing, medical and defense markets. The early models were impractical and did not adapt well to changing battery chemistries. In addition, the analyzers provided limited service and did not offer the quick test results and restoration capabilities customers demand today.

The last few years have brought a rebirth of the battery analyzer. With the move from the high-maintenance nickel-based batteries to the maintenance-free lithium-based packs, the duty of a battery analyzer is changing from life-extending cycling to rapid testing and boosting.

Fixed current analyzers

There are two basic types of battery analyzers: the fixed current and programmable versions. Fixed current units are the lower priced of the two, and charge and discharge a toshiba satellite a350 battery at a preset current of about 600mA. Smaller batteries get serviced reasonably fast but larger batteries are slow. The service time of an 1800mAh battery is three times that of a 600mAh pack. The capacity readout is in mAh and reflects the length of discharge. The fixed-current analyzers are the predecessors of the programmable units.

Programmable analyzers

The programmable analyzers allow servicing the battery against preset parameters. The charge and discharge currents are adjusted according to the battery rating, and the voltage is set to flag batteries with incorrect voltages. These analyzers provide more accurate readings and enable higher battery throughput than fixed current units. In addition, programmable analyzers are better suited to service new battery systems and have proven to be more effective in restoring weak batteries. The Cadex C7000-Series are such programmable toshiba satellite a200 battery analyzers.

Battery adapters

Interfacing the batteries has always been a challenge with battery analyzers. Technicians have invented contraptions with springs and levers so complicated that only they themselves are able to operate. Everybody else stays away from them of fear.

Cadex solved the battery interface issue with the custom adapters for common batteries and the universal adapters for specialty packs. The custom adapters are the easiest to use and provide the most accurate test results. User-programmable cables accommodate larger batteries or assist when no adapter is on hand. Smaller batteries can be serviced with the Cadex FlexArm™. Two contact probes mounted on flexible arms provide the connection when lowered to the battery terminals. Magnetic guides keep the battery in position and a temperature sensor safeguards the battery.

The Cadex adapters contain a memory chip that configures the analyzer to the correct setting. Each adapter stores 10 battery configuration codes to service 10 different battery types. The parameters can be edited with a few keystrokes on the analyzer's keypad.

Service programs

Advanced battery analyzers are capable of evaluating toshiba pa3594u-1brs battery conditions and implementing corrective service to restore weak performance. The Cadex system, for example, automatically applies a recondition cycle to nickel-based packs if a user-selected target capacity cannot be reached. Other programs include Prime to prepare a new battery for field use, Charge to allow fast-charge and Custom to apply unique cycles composed of charge, discharge, recondition, trickle charge or any combination, including rest periods and repeats.

Many modern analyzers also offer battery rapid test programs. This often requires entering the battery voltage and rating (in mAh). To obtain accurate readings, a battery-specific matrix may also be required. The Cadex QuickTest™ stores the matrix in the battery adapter, together with the configuration code. Installing the adapter sets the analyzer to the correct parameters, transparent to the user.

With the Cadex system, the matrix is commonly included when purchasing the adapter. If missing, scanning several batteries with various state-of-health conditions creates the matrix. The test time is 3 minutes and requires a charge level of 20-90%. If outside this range, the analyzer automatically applies a brief charge or discharge.

Many batteries are discarded, even when restoration is possible. Cell phone dealers have confirmed that 80-90% of returned mobile phone batteries can be repaired with a battery analyzer. However, most dealers are not equipped to handle the influx of warranty batteries and the packs are returned to the manufacturers for replacement or are discarded. Rapid test enables checking the battery while the customer waits. Minor toshiba pa3450u-1brs battery problems can be corrected on the spot.

A typical failure of lithium-ion batteries is excessive low discharge. If discharged below 2.5 volts per cell, the internal safety circuit deactivates and the battery no longer accepts charge with a regular charger. An excessive low discharge can occur if the battery is not recharged for some time after a full discharge through extensive use.

The Cadex battery analyzers feature Boost, a program, which reactivates batteries that appear dead. Boost works by applying a gentle current to the battery to re-energize the safety circuit and raise the cell voltage. After reaching the operating voltage, the battery can be charged and tested normally. Boosted batteries perform flawlessly as long as a repeat deep discharge is avoided.

Printing

Most analyzers are capable of printing service reports and battery labels. This feature simplifies maintenance, especially in a fleet environment where the operators must observe periodic service requirements. Printed reports also benefit customer service staff and engineers.

Labeling the batteries with service date and test results is self-governing in the sense that the user only picks a properly labeled toshiba pa3819u-1brs battery and has recently been serviced. Batteries with past due service date are segregated for service. With such a system, the user has full confidence that the battery will last through the shift, with energy to spare. Weak batteries are weeded out.

How Notebook PC to make the battery last longer

A laptop that comes with a battery such as dell inspiron 9400 battery for driving the body. Unlike batteries and battery, usually accounts for 10 percent of the unit price from 20% in the prices of its major models only. Such batteries can, leave them in the use of desk UPS (uninterruptible power supply) in addition to use as a instead of just a useless treasure, if you buy in bulk and companies to buy in order to hold down costs without battery Sometimes it seems like.

Would in some things and less about an hour battery life even when used in maple place unique laptop, AC a lot of people move with the adapter, even to get aware of the position of the battery more , especially in portable applications with battery briefly very important.

As mentioned previously, one million laptop batteries in the very expensive things cheap, with prices as there are things they can buy low-cost desktop PC with a high-capacity battery. Tens of minutes driving time of short, long or 10 hours of combined battery capacity, on average is about 2 hours. Better battery life in the catalog, "one to three hours," but things are written so that if you use these three hours is not a good two hours, I normally just over an hour Using Mashou.
Batteries used in notebook computers can be classified into several types such as in alkaline batteries and manganese.

As the laptop battery such as dell inspiron 1520 battery for almost obsolete for years, not only the secondary battery from the old laptop (used to recharge the battery) has been used as a long time. There was observed in memory when the charge is not fully discharged state.
Such as secondary batteries are commonly used. Low-cost laptops are often used to lower costs. A memory effect.

Batteries used in portable devices ranging from mobile laptops. For users with no memory effect, so light can be used conveniently. Special attention should be made so that material could ignite and rough handling. In general use I have not even worry too much. Recently, polymer electrolyte (polymer), light shape even more freedom to use, "Richiumuporimabatteri" has been adopted because some models appeared.

Rechargeable battery has a life expectancy is generally less time or it can be used hundreds of times used, this is the same for your laptop battery. The notebook computer battery is removable and may trouble releasing. If the portable notebook, and Unplug the internal battery in the battery itself can easily replace it yourself is difficult when it becomes available because the battery is bad, it becomes treated as fixed. In this case, it takes both time and cost considerably. It is useful to think of the future and inexpensive for you to choose models with built-in dell latitude d600 battery for easy removal if anything, can be difficult to obtain a replacement battery after a few years after the release of the model, such as when a minor model There is also careful with the neighborhood.

In order to preserve the battery, if the batteries have memory effect, better to charge the end-use, if you care even overcharge and over discharge, like a trick and this seems to be small. If you have more than one batteryn for example dell battery is no problem as I use every other week, AC tie would leave even less power is unquestionable. Battery is degraded in anyway even with hundreds of care may be better not too nervous.

Renewable Energy News – Printed Battery Technology Unveiled

a technology similar to printing solar cells, Xerox’s Palo Alto Research Center (PARC) has developed a process to “print” batteries with the potential for far more energy storage capacity than lithium ion batteries. Metal air batteries, such as the acer extensa 5220 battery, have the potential to to provide more energy capacity than lithium ion batteries, however this is dependent on the development of air cathodes that support the power density in order for it to be viable in applications where economy, space and weight are major issues – such as electric vehicles.

PARC says it has developed a process using co-extrusion printing to deposit thick films of functional acer aspire 5920 battery materials onto substrates, which provides up to10 times the air-breathing surface area of conventional electrodes. The pastes of functional materials can contain water-repelling materials such as Teflon interleaved with hydrophilic (“water-loving”) electro-catalyst material.

The deposition can be as narrow as several microns wide and as high as several hundred microns.
PARC is interested in further developing the technology with commercialisation partners in the acer aspire 5536 battery and fuel cell industries or in the materials or equipment markets that service the sector.

PARC has a long history of technology innovation and research, spanning back over 40 years. The company is also behind the second generation of solar concentrators such as those used in the solar farm at Alice Springs airport, which was the first solar electricity generation facility of its kind in the southern hemisphere.
PARC also invented “electronic reusable paper” in 2000, a thin, flexible material that can display graphics and text when an electric charge is applied to it.

New Lead Acid Systems

Lead acid batteries continue to hold a leading position, especially in wheeled mobility and stationary applications. This strong market appeal entices manufacturers to explore ways to make the batteries better. Improvements have been made and some claims are so promising that one questions the trustworthiness. It is no secret that researchers prefer publishing the positive attributes while keeping the negatives under wraps. The following information on lead acid developments was obtained from available printed resources at the time of writing.

Firefly Energy
The composite plate material of the Firefly Energy battery is based on a lead acid variant that is lighter, longer living and has higher active material utilization than current lead acid systems. The battery includes foam electrodes for the negative plates, which gives it a performance that is comparable to NiMH but at lower manufacturing costs. Design concerns include microtubule blockage through crystal growth during low charge conditions. In addition, crystal expansion causes a reduction of the surface area, which will result in lower capacity with aging. Pricing is also a concern. It currently costs about $450 to manufacture a Firefly battery as opposed to $150 for a regular lead acid version. Firefly Energy is a spin-off of Caterpillar and went into bankruptcy in 2010.

Altraverda Bipolar
Similar to the Firefly Energy battery, the Altraverda battery is based on lead. It uses a proprietary titanium sub-oxide ceramic structure, called Ebonex®, for the grid and an AGM separator. The un-pasted plate contains Ebonex® particles in a polymer matrix that holds a thin lead alloy foil on the external surfaces. With 50–60Wh/kg, the specific energy is about one-third larger than regular lead acid and is comparable with NiCd. Based in the UK, Altraverda works with East Penn in the USA, and the battery is well suited for higher voltage applications.

Axion Powe
The Axion Power e3 Supercell is a hybrid battery/ultracapacitor in which the positive electrode consists of standard lead dioxide and the negative electrode is activated carbon, while maintaining an assembly process that is similar to lead acid. The Axion Power battery offers faster recharge times and longer cycle life on repeated deep discharges than what is possible with regular lead acid systems. This opens the door for the start-stop application in micro-hybrid cars. The lead-carbon combination of the Axion Power battery lowers the lead content on the negative plate, which results in a weight reduction of 30 percent compared to a regular lead acid. This, however, also lowers the specific energy to 15–25Wh/kg instead of 30–50Wh/kg, which a regular lead acid battery normally provides.

CSIRO Ultrabattery
The CSIRO Ultrabattery combines an asymmetric ultracapacitor and a lead acid battery in each cell. The capacitor enhances the power and lifetime of the battery by acting as a buffer during charging and discharging, prolonging the lifetime by a factor of four over customary lead acid systems and producing 50 percent more power. The manufacturer also claims that the battery is 70 percent cheaper to produce than current hybrid electric vehicle (HEV) batteries. CSIRO batteries are undergoing road trials in a Honda Insight HEV and show good results. Furukawa Battery in Japan licensed the technology. The CSIRO battery is also being tested for start-stop applications in micro-hybrid cars to replace the lead acid starter battery. This battery promises extended life when exposed to frequent start-stop conditions and is able to take a fast charge.

EEStor
This is the mystery battery/ultracapacitor combination that receives much media attention. The battery is based on a modified barium titanate ceramic powder and claims a specific energy of up to 280Wh/kg, higher than lithium-ion. The company is very secretive about their invention and releases only limited information. Some of their astonishing claims are: One-tenth of the weight of a NiMH battery in a hybrid application, no deep-cycle wear-down, three- to six-minute charge time, no hazardous material, similar manufacturing costs to lead acid, and a self-discharge that is only 0.02 percent per month, a fraction of that of lead acid and Li-ion.

Laptop and Battery by Shane Sparks

Professors trade stories about seizing the cell phones of students who text during class or whose tones sound during a lecture.

Frank J. Rybicki, assistant professor of mass media at Valdosta State University, did the equivalent last week when he shut the laptop of a student who was allegedly web surfing as opposed to taking notes. She filed a complaint (reportedly about a finger or fingers that were hurt when he shut the laptop) and the university’s police arrested him on a charge of battery. The Georgia institution suspended his teaching duties there, although not his pay.

Reached on the phone, Rybicki confirmed his arrest and suspension, and said that he had been told by the university not to answer questions about the incident. He did say that the article and comments in the student newspaper, The Spectator, were accurate. That article quoted students who saw the incident as saying that Rybicki closed the laptop amid an argument with the student over his view that she had been on websites not related to the course.

The article also quoted students of Rybicki as saying that they were concerned that an outstanding professor had been arrested and might have his career disrupted. (Rybicki does not have tenure.)

Comments on the site said that the student had been warned to stop surfing the web and had ignored the professor. Generally, the comments were supportive of the professor and critical of the student. “Arrested for dell battery. For closing a laptop? Did it break the students fingers or something? I was thinking he hit a student with a computer. Simply closing it may be a little trivial to ruin a man’s entire life over don’t ya think?” said one comment.

The comments from those saying that they were in class suggested doubt about the extent of the injuries to the student’s fingers and surprise that the incident had led to an arrest. Another comment said: “If this teacher shut the laptop so hard that her arms were somehow mangled, fine … but seriously, she had PLENTY … PLENTY of other options. A. Don’t be so rude in a classroom. B. If you are going to play on your laptop … either don’t take the laptop(laptop battery) to class, or don’t take yourself to class. C. Do what the teacher says for half a second; he/she probably knows more than you do so grow up and take some responsibilities; College isn’t another episode of High School where you can get away with being a distraction; some people here WANT to learn, if you don’t care, … then get out! Or at least be somewhat polite.”

While he declined to discuss the incident specifically, Rybicki did answer a few questions. Asked if students shouldn’t look at non-class websites while in class, he said that was “pretty obvious.” Asked if he had ever caused physical harm to any student, he said “absolutely not, never.”

Several students who were in the class said that they were told by the university not to discuss the incident. The head of the Faculty Senate referred all questions to the university’s spokeswoman, Thressea H. Boyd. Via e-mail, Boyd said, “The university is investigating an incident involving a faculty member and this matter will be processed through the appropriate legal channels. In terms of class instruction, modifications have been made. All employees are expected to perform their obligations and responsibilities in a professional manner.”

As to university policy on laptop use in class, she said that “the use of computers during classroom instruction is within the discretion of each professor at the university.”

Samuel Logan, a Valdosta State student who was not in the course, but who has taken other classes with Rybicki, said via e-mail that he admired Rybicki. “He cares about his students and our grades, always making sure we do our best.” As for what reportedly happened in class, Logan said that an arrest “was not justified because he is a great teacher and she was on Facebook, when we know not to be on other sites while the teacher is teaching.”

Toshiba laptop battery recall

Toshiba said this morning it is calling back and will be replacing about 340,000 laptop computer batteries worldwide, the third recall of faulty batteries made by Sony in less than six weeks.

The toshiba battery, used in Dynabook and Dynabook Satellite laptops manufactured between March and May this year, could fail on the road because of problems with storing and transmitting power, Toshiba said.

Spokesman Keisuke Ohmori declined to estimate the cost of the move, saying it would not affect earnings, and would not say whether Toshiba was asking Sony to foot the bill.

Toshiba said that the faulty batteries would not cause fires. Although the batteries would die ‘only in rare cases’, that could happen regardless of how carefully they are used, Ohmori said.

Last month Dell and Apple Computer recalled almost 6m Sony-made batteries, saying they could produce smoke and catch fire.

Fujitsu and Hewlett Packard, which also use Sony batteries in their laptops, said no battery problems have been reported in quality control checks.

Choosing The Correct Laptop Adapter For Your Laptop

Choosing the correct laptop adapter is all a matter of voltage, output power, and proper connection. If all of these things do not match the original specifications of your computer, than a new laptop adapter will likely not work on your machine and may potentially cause a lot of damage. In the end, most replacement adapters will have a list of computers they are compatible with.

The first thing to consider for the laptop adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V attached to it, such as 19.5V. This information is also available on the original adapter, if it is available.

The second thing to look for is the current output needed for the toshiba laptop adapter. This number will have an A of mA associated with it. For example, it may say something like 4.7A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

Once these two issues have been settled, the other important step is simply to make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the laptop adapter will not matter if it is not able to be connected. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.

Many may choose the safest route possible and go with a replacement laptop adapter directly from the manufacturer, if available. While this is a good option, these parts may be more expensive than others that may be available from after-market manufacturers. Further, as long as the numbers match, all should work nearly the same and be just as safe and effective.

Another thing to consider is whether you want an dell AC laptop adapter or DC adapter. An AC adapter is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapter is made for automobile use.
