The right battery for the right application

The battery purchase is confusing for many consumers: If you stand in the store, you often do not know which battery you need: AA, or it was a Micro? And what about the variety of other names on the packaging: AAA, AA, LR6 or R20? What's behind it? Then there is the matter with the "chemistry" in the Dell Inspiron 1525 battery: Should it be a zinc-carbon battery or is perhaps an alkaline-manganese battery is the better choice? Or even lithium? And then there are also different batteries. That's a lot of information about the small energy powerhouses that make our mobile lives.

Micro, AA, C, Mono ... - The battery size

Batteries are first classified according to their sizes. There are different terms that are due to different standards. The general model designations have been established in modern usage set: Micro, AA, C, D and 9V block are concepts with which we refer to different sizes of batteries, which are reflected but not often on the Dell Inspiron Mini 9 battery. There are names such as LR6, AA, the AA and my example to reflect the identifier in accordance with international standards. Sun is hidden behind the symbol, for example, the IEC LR6-term for AA-size alkaline batteries. Is the other hand, is a zinc-carbon Dell Studio 1737 battery of the same size, this is indicated by the abbreviation R6. The AA letter code on the other hand goes back to the American standard. To ease this confusion for the consumer as possible, Panasonic has introduced its battery-packaging the Yellow label, which carries the two most important codes in themselves, and thus makes a clear type of statement - by S for micro-, M for AA L is for baby and for mono-XL Dell xps m1330 battery . The consumer can be guided more easily.

Ratios of different battery sizes at the Battery total sales

With 61.91% of the AA out in Germany on the hit list of the most common Dell XPS M1730 battery sizes. She was in last year's best-selling standard size. Far behind follows with a share of 20.60%, the micro-battery as a second. The last places share the baby (8.68%), the mono (5.80%) and 9V (3.01%).

History of Battery Technology II

As pioneers of the nickel-cadmium batteries are the two inventor Thomas Alva Edison and Waldemar Jungner. They explored the field of electrochemical energy storage and reported in 1901 to the first patents for nickel-iron-and nickel-cadmium Dell XPS M1530 battery . They are also considered ancestors of the zinc-air battery technology. The decisive step towards commercial use of NiCd batteries succeeding only Neumann in 1948 with the description of a patented gas-tight housing for the Dell Studio 1737 battery technology.
Due to the high environmental standards replaced the battery manufacturer in the early 90s, the highly toxic heavy metal of NiCd batteries by a metal-bonded hydrogen. Thus began the triumph of the nickel-metal hydride Dell Vostro 1310 battery.
With the increasing popularity of mobile IT equipment and the related desire for light and powerful batteries with small dimensions, the industry developed in the mid 90s, the lithium-ion battery. With the continued miniaturization of devices, manufacturers demanded variable Dell Inspiron Mini 9 battery casing forms of Li-ion technology. In 1993 came the lithium-polymer battery, which today is mainly used in small devices such as mobile phones or PDAs.
Great hopes on the Dell Vostro 1510 battery to the fuel cell developers as the future performance of energy. Already in 1839 the physicist Sir Robert Grove set the stage for this technology. He developed the first working prototype. This consisted of two platinum electrodes which were located in separate glass cylinders. Grove filled a cylinder with oxygen and the other with hydrogen and dipped them in a dilute sulfuric acid (electrolyte). This structure produced a measurable voltage and is considered a prototype of the fuel cell. After this discovery, the fuel cell technology long forgotten. Only in 1950 discovered the military and space technology back to the compact and efficient energy source. Since the beginning of the 90 research scientists and the use of fuel cell technology in the industrial / commercial environment - with good future prospects.

Tips for longer run time and life

The majority of mobile devices working with lithium-ion batteries. These donors have chemical energy under defined circumstances and with appropriate use of a particular food and running time. If they are not met, shorten these values significantly. Thus, the user can decide which affect battery life and length of life and delay an expensive Dell Studio 1735 battery purchase.
The most important criterion for in-use lithium-ion battery at an ambient temperature is 20 to 40 degrees Celsius less than ideal. If this is not clear, appropriate cooling measures provide for heat dissipation. Extreme low temperatures should be avoided by the user.
For example, are Notebooks over a longer period of time not in use or in a docking station, the user should remove the batteries from the unit and store in cool dry conditions. This minimizes the self-discharge and the chemical decomposition process of the Dell XPS M1530 battery cell. In this regard should also be frequent, unnecessary to avoid charging and discharging of the battery and mini-cycles.
Meanwhile, some companies have focused on the distribution of so-called identical replacement batteries and repair of notebook batteries. Depending on battery type, the customer can save a lot of money here. However, one should consider the offer carefully, because the quality of these Dell Latitude E6500 battery is not always evident. Especially with old notebooks, for which there are no more replacement Sony VGP-BPS2C Battery , may be worth a repair or the processing of the battery pack. (Hal)

Batteries: The proper care and affordable alternatives to original batteries

In mobile devices, the battery is one of the vulnerable components. But who protects and cares for the energy donor, the running and significantly extend lifespan. tecCHANNEL gives tips on how Dell Latitude D630 battery last longer and show alternatives to the original purchase of batteries.
The main criticism of mobile workers mainly concerns the short battery life. By improper use time shrinks the running time of the energy donor to the significantly faster. Even after a relatively short period operation is initially reached only a dream. Who will protect the battery from the beginning, studying carefully before using the device of course the manual. But even here, the customer is not sufficiently informed about the proper use of batteries often elucidated. So you running and life of your Dell XPS M1530 battery cells optimally exploit has tecCHANNEL the most important tips for dealing with lithium-ion batteries together. We will also give useful hints for the care and storage of energy cells. For more basic information about the weaknesses of Dell Vostro 1510 battery pack, see our report: " Batteries: Nondurable factory. "
If the battery life passed its zenith, the purchase of a new energy suppliers is essential. But even here there are inexpensive alternatives to offer the original Dell Studio 1537 battery
. Bid now so-called "Third Party" Lithium-ion batteries for many devices by leading manufacturers. These cost much less than the originals. But be careful! The "cheap" replicas are run in terms of duration and quality do not always equate with the original Dell Inspiron 6400 battery . Another way to renew old tired battery packs is the "battery repair". This method is also suitable for cases where batteries for a device are no longer available on the market.

The most important battery tag

Capacity:
The capacity of a battery is measured in milli-ampere-hours (mAh). 4500 mAh, for example, mean that the battery provides 4500 mA for an hour or three hours, 1.500 mA current. Then he is discharged and the voltage breaks down under stress. NiMH batteries of standardized size "AA", the one usually used in cordless phones and Digitakameras reach, currently has a capacity of 2,500 mAh. bring good lithium Dell XPS M1530 battery in laptops, it mAh to over 6,000.

Some manufacturers state in Li-ion battery, the stored energy in watt hours (Wh) at. This unit, but you can easily convert mAh: If, for example in the electricity dispenser 10 Wh and 7.2 volts, then divide these two values (10 Wh / 7.2 V) - the battery therefore has a capacity of 1,400 mAh .

Sorry, there are not standardized laptop batteries such as NiMH cells (AAA, AA, etc.), but there are a variety of laptop batteries. Therefore you should consider before buying a laptop replacement Dell Inspiron 6400 battery absolutely sure that he really fits well with the laptop.

Battery Laderat e:
This term is used, regardless the size of the loading or discharging of the battery capacity indicated. For example, a 1000 mAh Dell Studio 1537 battery with the charging rate of 3 C is loaded, is 3 times the charge current 1000 mA, or 3 amps.

Impedance or internal resistance:
The lower the internal resistance, the better the current flows. Increases the internal resistance in lithium Dell Inspiron 630m battery due to aging or (especially for nickel batteries) due to incorrect loading, then the powered devices switch after a few minutes of running again. With about 100 milli-Ohm NiCd cells have the lowest resistance, followed by Li-ion (150 milli-ohms) and Li-polymer battery (200 milli-ohms). NiMH cells with more than 200 milli-ohms to the highest internal resistance, which can increase with improper maintenance to over 350 milli-ohms.

Memory and lazy battery effect:
Nickel batteries are acidic when they are not required - then fails on NiCd batteries and the memory of NiMH cells of the lazy battery effect. Both effects caused by frequently to shop with low power (for example, the loading rate 0.1 C) or if you forget to unload batteries from time to time entirely.

It is this form of small crystals on the electrodes. The result: The operating time is reduced by up to 90 percent, because the internal resistance increases and thus breaks down the voltage under load. Except for one difference is similar to both effects: the lazy Dell Studio 1555 battery effect does not occur so abruptly as the memory effect. Modern lithium batteries do not know the memory effect, they suffer, however, among other weaknesses, particularly the limited lifetime.

How do I maintain the battery of my notebook right?

Each battery is a consumable item
Important to know is that each battery is a consumable item - compared to the shock absorber of a car. The first use, we know that he is eventually broken. The careful to deal with the battery, the longer it is used with an acceptable run time. The life of a battery is usually six months to about four years - depending on use. Below are a few tips and hints to be able to use the Dell Inspiron 5100 battery as long as possible ...

Memory effect
Usually found in notebooks today with lithium-ion batteries (Li-Ion) Use a relatively modern and easier to maintain battery type. The biggest advantage over the older types (nickel-cadmium NiCd, Nickel-metal hydride NiMH) Is that he does not have a so-called memory effect. So it does not matter if the battery is empty or partially loaded when a load is taking place. The Dell Vostro 1000 battery is always in full capacity. With the older types were called the memory effect when the battery was charged when he, for example, yet a third was loaded. Then after that were also only two-thirds of the capacity that the battery has less "Pinned" in which state it was loaded.

Commissioning
Usually batteries from the package are not or only partially loaded. It is therefore important at the beginning of a notebook battery to life. Given the best Notebook infected overnight at flowing through it. Thereafter, the Notebook operate solely on the battery until this battery is empty, and then reload it completely. After about three to five such cycles the Dell Vostro 1510 battery has reached its maximum capacity and this has now more or less over a long period of time.

Shop
As occurs in modern batteries no memory effect, it does not matter whether a battery will be fully charged or only partially. It is recommended, however, after about 50 charge cycles to perform a full charge. Just the Notebook run with, for example, a DVD movie until it shuts itself. Then fully charge the battery.

Storage
Batteries are very temperature sensitive. In any case, you should avoid freezing temperatures and extremely high temperatures. In summer or winter, it should therefore be avoided in any case to let the Dell Studio 1537 battery for an extended period in a parked car.
The ideal storage temperature for Li-Ion batteries is about 15 ° C, the battery should it be loaded to about 60%. Then the self-discharge is the lowest.

Work on the current
If you over a longer period the Notebook operates at the socket, the battery should be taken out.
Reasons for this are:
* The Notebook with current operation is relatively warm. As noted above does not heat the battery well.
* The self-discharge the battery loses power in operation at capacity. If a certain threshold is exceeded (eg 99.5%), then sets the electronic charging of a notebook and charges the battery back to full capacity. This process can be repeated on a weekend a few times. Each battery has a limited number of charge cycles, is its capacity to almost completely exhausted. Most laptop batteries last about 500 to 1000 charge of operations - while it does not matter whether a charging process takes from 99% to 100% or from empty to 100%. It is therefore possible to avoid "unnecessary" charging cycles.

Self discharge
Each battery will lose - not that it is used - always on power. This is called self-discharge. For longer storage, a rechargeable Dell xps m1330 battery so you should periodically check the state of charge, so that the battery by "discharge" is not damaged or defective may completely go. If necessary and if it is not further used, the battery should turn to about 60% load.
The self-discharge for Li-ion battery is approximately two to three percent per month at room temperature. The higher the temperature, the higher the self-discharge.

Ten times better battery in view

A process for the tenfold increase in capacity of Li-ion batteries developed Scientists at the University of Stanford. With the help of silicon wires of nanometer size.

Example, instead of just two hours of notebook batteries in the future could hold 20 hours, the battery life of MP3 players, cell phones, digital cameras and other mobile devices based on a Li-ion Dell Vostro 1000 battery could increase tenfold. Researchers at the U.S. university stanford have also developed a process by which the capacity of lithium-ion Dell Inspiron 1501 battery can be extremely high. For use in nano-meter tiny silicon wires. So far, the use of Silizum as the anode to absorb charged Li atoms was difficult because during the recording and subsequent release of the first and then subsides. The result: the Dell Latitude D830 battery loses much of its performance. If the material in the form of nanowires, there is the structure of the silicon.

Not only to improve but even a revolution, the researchers at Project Yi Cui in the art. The market opportunities are considered very good: According to Stanford techniques are developed for processing silicon high, which is a mass production of high-capacitive Dell XPS M1730 battery are no obstacles. When the first products hit the market, but it is still unclear. Currently being considered include a collaboration with a Dell XPS M1330 battery manufacturer.

Laptop batteries

The shareware Cool CPU for Windows 95/98/ME, 2000 and XP, 900 KB, Registering: 15 € supports), many Chipsets for Intel and AMD processors. The freeware CPU Idle Extreme (For Windows 98/ME, NT 4, 2000 and XP, 557 KB, Registering: 30Euro) on processors from Intel, Cyrix and AMD in the waiting state to a low-power mode. For users of a notebook with an AMD CPU is the freeware VCool interesting (for Windows 98/ME, NT 4, 2000 and XP, 110 KB).

Note: Tools such as Cool CPU, CPU idle and VCool are due to the system settings were only suitable for experienced users. They also do not work properly on any notebook. In particular, the tools provide only with older notebook processors with a fixed clock rate of satisfactory results. On modern CPUs with dynamic throttling - for example by Intel's SpeedStep - the tools can lead even to a higher power.

The optimal treatment of a Li-ion batteries in many cases the purchase of a replacement Dell Inspiron Mini 9 battery superfluous, or at least postpone. Nevertheless, aging notebook batteries and are losing their capacity. After about two to three years, or about 750-1000 charge-discharge cycles also has a carefully cultivated battery fulfilled his duty is over. This value is, however, a rule of thumb, from which it can ever be on battery condition and usage habits are significant differences.

A brand new replacement Dell XPS M1330 battery designed to be the easiest course directly with the respective manufacturer of the notebook. However, the provider usually long heavily: Between 150 and 300 € to you depending on the type expected for a Li-ion replacement. You can buy more batteries usually about three years. Because aging and unused batteries, you should buy the replacement, but only when you need it actually. The best way to inform the manufacturer, how long each battery type is still available.

Cheaper than original batteries are memory cells of third-party, as it on numerous websites such as Ebay get offered. The prices are usually much lower than the original manufacturer. In the past, offered by low battery manufacturers often a cause for criticism, especially regarding the Security. Among other things, overcharging some providers gave up a protection against electronics. Replacement batteries of inferior quality, you can not see outside, however. If you are interested in the Dell XPS M1530 battery of a third party, you should seek assurances from the dealer so that the battery is identical to the original.

An alternative to buying a several hundred € Neuakkus expensive is the repair of the defective batteries. That's the only way to be able to continue working independently with the notebook from the wall outlet when the required battery type is no longer available commercially.

In the repair of the existing battery is reprocessed by the defective energy cells are replaced with new. This works with both older NiMH batteries, and also with new Li-ion cells. The existing electronics in the battery is maintained, unless it is damaged. If it is over, the Dell Inspiron 1525 battery can not be serviced by a cell exchange.

And so the overhaul: The workshop, which provides service, first opens the sealed plastic housing of the battery. They then checked the electronics, remove the existing batteries and is building a new functionally identical. Then the case is closed again. Because it does not prevent opening and adhesive residue can be considered under the repair usually suffers the stability of the Dell Inspiron 1501 battery housing.

A positive side effect of the cell exchange: Some repair shops often use more efficient cells types, which works the same as the previous battery. This way you get to the original part of a more powerful battery.
