Know Your Phone Battery
September 3rd, 2009 by ftsThe only source of energy is a battery cell phone, as good and clever as any of a cell phone will not be able to function without the energy from the battery. The following article about cell phone batteries, including some things that must be understood by engineers associated with mobile phone batteries, such as sistemasi how to work a cell phone battery, charging the optimal techniques include reviving a weak battery.
Battery used for the phone type rechargeable batteries (can be charged again). Until now commonly used in portable devices such as mobile phones are: Nickel-Cadmium (NiCd), Nickel-Metal-hydride (NiMH), Lithium-Ion (Li-Ion) and Lithium-Polymer (Li-Polymer).
Function battery that is changing the chemical energy into electrical energy that can be used as an energy source. The battery has 3 important components of the positive electrode, negative electrode and electrolyte materials that lie between the second electrode. Electrolyte materials which will react to produce electrical energy to then be distributed through positive and negative electrode.
The types of rechargeable batteries:
1. NiCd Battery
Characteristics of NiCd batteries:
• nominal voltage of NiCd battery cells are 1.2 volts
• The battery is a higher nominal voltage of several series connected cells
• Excess NiCd batteries other than the three types is the ability to handle high loads
• In addition NiCd batteries 5x faster in-charge than NiMH batteries or 20x faster than lithium batteries, because it can use a fast charger
• The disadvantage compared to lithium batteries is the low storage capacity, the ratio of power / weight is lower, and the memory effect
• In addition NiCd batteries that have been in-charge can empty itself (self-discharging) even if not used. Approximately 22% of energy lost in 24 hours.
• NiCd battery that is weak should not be directly in charge.
• NiCd battery must be vacated until completely discharged before the charge.
• If required by more than 10 hours with a low flow will rapidly weakened due to memory effect, the battery is not able to work although fully charged due to precipitation of metal crystals on the negative electrode so that the reduced battery capacity, impedance (resistance of) increasing the voltage drop that occurs when charged, the battery only works for a while.
2. NiMH
Characteristics of NiMH batteries:
• nominal voltage of NiMH battery cells are 1.2 volts
• Self dischargingnya smaller than NiCd batteries, depending on the typenya about 6 - 16% of energy will be lost within 24 hours
• charging the wrong way will cause the battery is not working normally, although the battery is fully charged but will be declared out even if used for a while. (normal but measurable voltage drop directly when loaded) condition is called lazy battery.
• NiMH battery can hold 2x more energy than a NiCD battery pack
3. Li - Ion
Characteristics of Li - Ion
• Nominal voltage Li-Ion battery is 3.6 volts
• Electrolytes in Li-Ion battery is very reactive, bocorannya can cause corrosion to equipment
• Li-Ion battery is placed in a metal casing that is stable and strong
• microcontroller and the sensors mounted on the casing to prevent excessive heat and overcharging.
• energy density of Li-Ion battery capable of storing energy 3x more than a NiCD battery pack
• Li-Ion battery has no memory effect and lazy battery so the battery does not need to emptied before the charge.
• Self discharging also smaller at around 10% within 24 hours
• Impedance (prisoners in) Li-Ion battery is higher compared to NiCd and NiMH, of 200 - 250 m & ± (milli ohms). The result is fast becoming a hot battery and voltage drop when loaded too heavy
• Lithium is highly reactive chemicals in the battery will decompose naturally and after 2 years of battery becomes unusable.
4. Li-Polymer
Characteristics of Li-Polymer battery
• Nominal voltage Li-Polymer battery is 3.6 volts
• Slsktrolit in Li polymer battery is solid and not so simplistic raktif battery casing
• Li-Polymer battery can be made in the size of a very thin and flexible so that the appropriate sized equipment used in the Mini
• Compared with Li-Ion battery, Li-Polymer battery with a capacity of SAMS lighter weight 10 to 15%.
• Li-Polymer battery more quickly loses its capacity.
5. DMFC (Direct Methanol Fuel Cell)
• The battery is a battery that of material using a liquid fuel cell where the composition of fuel mixtures of hydrogen with oxygen to produce electrical power, heat and liquid.
• Results of the chemical reactions that occur to produce a high energy density, it is at the advantage compared to DMFC Lithium ion battery
• DMFC has a 10x improvement in Volumetric energy density.
Unfortunately the battery has not been much used officially still in testing in some phones.
NiCd and NiMH batteries
- Caring for the right
Nickel battery will live longer if the charge using the fast microprocessor controlled charger. Charger should be able to discharge to eliminate memory effects and lazy battery. If stored longer, the battery should be discharged nickel contents in advance and stored in the refrigerator (but not in the freezer).
- Refreshes the battery
NiHM fast losing its capacity and weak. This situation arises especially when used to fill empty batteries yet (lazy battery effect). To refreshed again, use the battery care features on the phone menu. With this feature will be emptied until the battery is completely discharged, then the full conditions, if the phone does not have this feature, turn on the phone until the phone battery die out and only then in charge.
Battery Li-Ion and Li-Polymer
- Beware of the old stuff!
Lithium is highly reactive, may have chemicals inside the battery is loose so that the battery capacity even lived half of the unused battery. Carefully before buying so as not to get the old stuff! Moreover asphalt products. Should ask for guarantees and warranties from the seller to know How to Distinguish Genuine Or phone battery Asphalt (Original Fake).
- Damage due to too often in charge
Lithium batteries hold the charge only 300-500 times, and then the battery capacity decreases and the battery is damaged. To extend the life of lithium battery, do not be too much to charge, do Rechargeable Battery HP correctly . As charging when the battery is completely empty, thus charging frequency is reduced.
- Fill your new used used
Do not immediately turn on new mobile phone berbaterai Lithium. The contents of the battery was fully optimized and their capacity to outlive. If the battery is not in use store in the refrigerator (not the freezer).

MP3 And Technology
June 9th, 2009 by ftslaptops are essential parts of our lives. Do you what it takes to run a laptop. You guessed it- laptop charger. Some of these laptops are so weak when it comes down to there batteries it is a joke. I have always had problems with laptop accessories.
MP3, for better or for worse, you revolutionize the world of music and has, again, to think the whole world on the protection of copyright, not only in that field but in all those domains has invaded the internet today. For those still unfamiliar with the topic MP3 (short for MPEG 1 Layer 3) can be defined as “one of the best and most popular way of storing audio on a computer. This format significantly reduces the size of a audio track on a CD. The MPEG 1 Layer 3 algorithm uses a complicated psycho-acoustic model is based on the ability to eliminate those frequencies which the human ear can not hear, that is why the MP3 is not the same quality as a track from an audio CD (although it does not note). This new format dramatically reduces the size of an audio file in relation to the WAV format. The MP3 compressed into a 90% higher than the WAV file is not getting a very heavy.
To get an idea of a 50 MB WAV file to MP3 compressed not occupy more than 6 Mb This is why this format is revolutionizing the world because of its small size you can download from the Internet (something not previously could do with the WAV, but there are other formats like Real Audio, but do not possess the quality of an MP3). Thanks to the many MP3 players from around the world can be known only to burn their tracks to MP3 and put them in the network. ” For those still unfamiliar with the topic MP3 (short for MPEG 1 Layer 3) can be defined as “one of the best and most popular way of storing audio on a computer.

Blackberry repair can be, and is often expensive and a nuisance to the user leaving you immobile and unable to access your contact list sometimes at critical points whether it be for personal or business matters. I would like to therefore take a few moments and explain a process that can avoid not only Blackberry repair, but the inconveniences that go with it, and a process that can be extremely beneficial to anybody that carries out the alternative to having to wait for the Blackberry to undergo its repair maybe a few days, to a few weeks.
So, you choose to repair your Blackberry, you take it to a repair specialist, he then charges you to find out what is wrong with the device, charges you for the parts and charges you for the labor, and all this time your personal details are in the hands of the Blackberry repair specialist not very confidential in my opinion. And after all this you are left with a big sum to pay, which is something that even in the best economic situation is not greeted with a smile more so at these times of the financial state.
Therefore the alternative to consider against Blackberry repair would be to recycle, trade or sell the Blackberry that is broken or not functioning correctly this may sound crazy, how can you sell a broken Blackberry?
However, there are sites online that will pay a cash reward to take your broken Blackberry off your hands, meaning you avoid the repair, the repair costs and the inconvenience of your Blackberry undergoing a repair with a stranger and instead you get some cash to put towards a brand new Blackberry that will be problem free, in need of no repairs and at a discounted price thanks to the funds you received for recycling the broken device, which in fact has many benefits, not just to you but the environment also.

What You Need To Know About Cell Phone Batteries
May 24th, 2007 by AdminUsually what you know about your cell phone is only what its tipe is and how much did it cost you. Nothing more. Actually there is more that you need to know about your cell phone, which is your cell phone battery.
For starter, do you know if cell phones Cell phones manage on various kinds of batteries depending on the manufacturer, phone size or shape and features. Mainly, there are four types of cell phone batteries: Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.
The most up-to-date type is Lithium Polymer. This type applies the latest technology in DC power. This cell phone battery weights light and will not explode even if pierced. Also, the elements of the cell phone battery are covered in platic pouches and do not have memory defects. They last about 50 times longer than Nickel Metal Hydride batteries.
On the other hand, Lithium Ion is also efficient in storing memory and last longer than Nickel Hydride but they are quite lighter. This type of the battery has a tendency to cost more and would only suitable for new models of phones. Most Lithium-ion batteries apply a fast charge technique to charge up your cell phone quickly up to 80% capacity and then slowly bring it up to full power in about two hours. Nickel Metal Hydride is also efficient in storing memory and lasts longer than the NIM type about 40 times.
If you are the kind of people who need rapid charging and if used with a car charger can be fully charged under 1 hour, then this type of battery fit you best. The special form allows the energy to concentrate in a single pack, even it sometimes about twice the power of Nickel Cadmium. A lot of cell phone users prefer this type as it lasts long and is cheap. Of course, they are non-toxic and environmental friendly. Unlike Lithium Polymer however, Nickel Cadmium are the oldest type and has a lot of memory defects. Another serious disadvantage is that before you can charge them again, they will have to be totally discharged otherwise you may damage them irreversibly . Unfortunately, this type is highly toxic because of the presence of Nickel Cadmium and is gradually being phased out by cell phone manufacturers.
Usually batteries have 300 to 400 charge cycles in their life span.The fact is,the battery loses away some of its potency and thus become diminished in power anytime you charge your battery. , . The cell phone batteries can cost you a lot if you consider the fact that a Nokia 3310 battery can cost up to $24.95. Here are a few tips to prolong the life of your battery:
Before charging your cell phone batteries, you need to keep the batteries in a cool place and allow them to adjust to room temperature because the sharp rise in temperature upon charging can ruin them.
Your cell phone life is depending on the potency of your battery. You can rest assured that your cellular device runs and runs well for years if you know how they operate and how to care for them .
Don’t allow materials to get stuck on the terminals as that causes the battery to lose contact with the terminals resulting in improper connection.
How To Take Care Your Cell Phone Battery
May 24th, 2007 by AdminMaybe it never crosses your mind but have your ever thought of your cell phone battery to be the most important part of your wireless phone? If you don’t have the cell phone battery, your cell phone will not work no matter how high tech your cell phone is. So, actually how do we take care of our cell phone batteries?
1. Caring for the cell phone battery.
- Keep the cellular phone battery’s contacts clean. It means, you need to recharge the battery after periods of non-use to prolong the life of the cell phone battery.
