Into lithium-ion batteries and lithium batteries lithium polymer battery. Lithium-ion batteryelectrolyte is flowing, the polymer electrolyte is a solid-state lithium batteries and, therefore,lithium polymer lithium-ion battery is more than the unstable encounter external beat, or usenon-standard charger, may cause battery to explode. Many mobile phones, laptops, digital cameras and other portable electronic products used in batteries are lithium batteries. Buypoor quality lithium batteries, as his side put in a ”time bomb.” Therefore, when consumersbuy lithium batteries must note the following:
1. Capacity is clearly marked. No clearly marked capacity (such as 2200mAh or 4400mAh)lithium battery, it is likely that use of poor quality battery cell or battery cell recycling of waste batteries re-assembled. Market filled with many low-cost lithium batteries, is the use of recycled cells or disassemble the battery cell to do, the price is cheap, but life is short, inconsistent quality, the use of mistake may damage the phone, or even an explosion.
2. Standby time is guaranteed. Standby time after the battery into the phone to the nextcharge of continuous use. Lithium batteries on the market generally can not be guaranteedto the customer standby time, which is unstable because of the quality of the relationship between the battery, many batteries as is the use of cheap poor quality of the battery cell,so standby time is very short.
3. It with safety protection circuit. The nature of the lithium battery protection board must beapplied to prevent the lithium battery overcharge, over discharge and short circuithappening, without the lithium battery protection board will be deformation, leakage,explosion. In the fierce price competition, the battery packaging plant protection circuit fora lower price, or simply omit the device, making the market filled with potentially explosivelithium battery. Consumers can not tell from the appearance of the protection circuit boardout there, so the best choice to buy from reputable merchants.
Now calculate how many mobile devices around you? Mobile phone, MP3, tablet PCs, laptops, digital cameras, handheld, navigation, etc., these devices are battery powered mobile, and battery life is the most worrying problems. Mobile phone, for example, affect the battery life in addition to the system power factor, battery maintenance is also necessary to understand how the knowledge, unless you can live with replacing the battery or external battery backup, in fact, even the phone like the iPhone battery can not be replaced .
Maintenance may be a single battery charge-discharge cycles have little effect, but after a long time there is contrast, lithium-ion batteries after a year or more, there will be loss of battery capacity, and better maintenance of the battery wear and tear will be much better. Also circulated on the Internet before many of lithium-ion battery maintenance methods, but not the same. For example, after the new battery to get back to full 12 hours before emptying, the maximum capacity of three times to activate, but also say that once a month to complete charge and discharge process is conducive to maintenance.
Battery University Site recently released an article on how to extend the battery life of the article, use the battery put new conclusions. They claimed that, after experimental results confirm that lithium-ion battery is the best way to maintain mild use, fast filling up fast, which use similar machinery and equipment, with greater frequency, the more the number, the more the loss of battery fast. The smaller the depth of discharge of lithium batteries, use longer, if possible, try to avoid frequent full charge and discharge.
The user, your battery life by 10%, 20% charge is the best on the remaining battery charge in 50% of the time you can, but try to avoid the phone prompts to start charging when power is low, no matter what the conditions are not the battery power runs out. If you go out, try to use the larger capacity battery or mobile power.
In addition, they also pointed out that the use of environmental temperature also have an impact on battery life, high (30 ℃) or too low a temperature will form a loss of battery life. Such as regular power adapter used to connect the laptop, it is best to remove the battery, the fact that the battery will not charge the formation of damage, because the battery will not charge after full charge, but do not pay attention when using the laptop at the bottom of ventilation will make the temperature hot, this is the impact on battery life murderer. Of course, if there is a better use of environmental or cooling base, the battery power when you can avoid losing unsaved data.
When the mobile phone battery shorter or memory effect of aging, many people will be directly replaced. If you are a good saver or a good discover, we will find that there aresome cell phone batteries repair method allows us to revitalize the aging of the battery.
This mobile phone battery repair recommended by many users is experimental and summed up, suggest you try. Will be discarded mobile phone batteries wrapped in newspaper, then the outside two layers of plastic wrap, then placed in the freezer, removed three days later, remove thepackaging into a cool place to dry for two days and then charge.
This mobile phone battery repair on a professional explanation: mobile phone battery charge and discharge process is a process during which cells within the yin and yang chargeeach other to pay the charge hit. The reason why more and more without the batteryused, because in a normal room temperature, the electron kinetic energy inside therelatively large, so the battery is active, leakage is relatively frequent. And the battery into the low-temperature environment, the surface of the lithium-ion battery electrolytemembrane and the micro-structure, and the interface they will change significantly, leading to the internal battery temporarily active, to reduce leakage current, so rechargethe phone’s until the power-up time will increase.
If you wanna your mobile phone battery in good condition, still have to pay more attention in the normal use of mobile phone battery maintenance, the mobile phone battery better for us. Please do not discard the discarded mobile phone batteries, the proposed transfer to a specialized mobile phone battery recycling point.
As we know, the lithium-ion battery technology is the fastest growing trends in the tool community. Lithium Ion batteries have the best energy to weight ratio, meaning they pack the most power with the smallest amount of bulk. They also experience no memory effect or, lazy battery effect. This occurs when a battery repairs can no longer accept a maximum charge for having been repeatedly recharged without being fully used (a common symptom of Nickel Cadmium (Ni Cd) batteries). Li-Ion batteries, conversely, have absolutely no memory and can continually accept a maximum charge. Additionally, Lithium Ion batteries have a very slow rate of charge loss while the battery is disengaged.
The difference is in the chemistry; a Lithium battery is a disposable power source composed of lithium metal compounds – the key word, here, being disposable; Lithium batteries can not be recharged. Lithium Ion batteries, on the other hand, are intercalated, meaning the lithium ion inside the battery repairs moves between two internal electrodes. This movement, or reversibility of the lithium ion accounts for the battery’s rechargeability.
Lithium Ion batteries hold a lot of power and are surprisingly light-weight, especially with consideration to other rechargeable batteries. Li-Ion batteries combine single cell technology with a greater energy reservoir than Nickel Metal Hydride and Nickel Cadmium batteries. They store more power for their size than both NiCad and NiMH. Li-Ion battery repairs hold their charge for significantly longer than other comparable batteries, and provide steady power until that charge is completely gone. Other batteries gradually and consistently loose power as you work. Li-Ion batteries stay strong until the last push.
The disadvantages with using Li-Ion battery technology are generally few and far between, and technological advancements are making them even less so. Manufacturers have recently improved the Lithium Ion recipe to reveal a more reliable battery. Still, every giant has its weaknesses:
Li-Ion batteries are sensitive to intense hot and cold temperatures. In extreme temperature conditions, the battery repairs will degrade more quickly. Li-Ion batteries degrade regardless frequency of use. The Li-Ion battery’s built-in computer chip tells the battery to refuse a charge once the batteries power falls below a certain point. If this occurs, the battery repairs is beyond repair.
General Li-Ion Battery Tips: On occasion Lithium Ion batteries require more than one charge (sometimes 2 to even 10) to accept a full charge. The first time you charge your battery, leave it to charge over night. This ensures you’ll have maximum power for your first use. To maintain proper balance in your battery repairs, leave it charge over night about once per week for the life of the battery. When buying a new Lithium Ion battery, make certain you are buying a fresh one. There’s a chance a battery has been degrading on the shelfs of manufacturer’s and distributor’s so be certain you are buying a new one. Most manufacturers provide a date code on the battery repairs or packaging. Check dates before you purchase, and be confident you are getting a fresh, high-performance battery.

Mobile phones are widely used in our daily life. Also,the mobile phone battery are well known by us. So do you know how to deal with them? A mobile phone without power is worth nothing, that’s why it’s important to ensure that your battery lasts for as long as your phone is connected to service. Sure, there are mobile phone batteries available for almost any model, however I am sure anyone out there would rather choose to have their original batter to last, than need to go searching for repair battery.
Then,let’s see what should be done in order to fully maintain your original battery repairs and get it to last as long as you have your mobile phone in use.
Before your mobile phone battery’s First Use, let lt Fully Charge.This is probably the most known, however due to it being very important we will put it first. New batteries should be fully charged before their first use to get maximum capacity. If your mobile phone has Nickel based batteries you should initially charge them for 16 hours and then run through 2 to 4 full charge-full discharge cycles. With Lithium Batteries, get them charged for about 5-6 hours. Make sure ignore the phone telling you that the mobile battery is full, as this is not accurate before the battery repairs has undergone the initial charge.
Remember that always charge your mobile phone battery correctly.Most new mobile phones have lithium-ion batteries, while the older ones usually have nickel based batteries. (Read the label on the back of the repair battery or in the technical specifications of your owner’s manual to determine your mobile phone battery type). Nickel-based batteries (NiCd and NiMH) have a phenomenon known as “memory effect.” This means that if you charge the battery repairs only partially, eventually the battery forgets that it can have a full charge. For mobile-phones with nickel batteries make sure to discharge them completely once every two to three weeks, this will prolong the repair battery life. (If you feel that your nickel-based battery is “suffering” from the “memory effect”, it can be reconditioned. In order to recondition the battery completely discharge it, then completely recharged (several times). This will help the battery repairs regain it’s duration.
It is absolutely that Lithium-ion batteries are completely different when it comes to charging. Lithium-ion batteries do not have the same memory effect. However, many devices that use lithium batteries have a meter that shows the user how much power has been left. Lithium-ions oxidize in the battery repairs, thus shortening its life. After a certain period of time, the battery exhibits slightly different electronic properties, which the device can only detect when the repair battery is completely discharged. This type of problem is known as a virtual memory effect and it’s “symptoms” are when you notice your battery meter shows a high charge, then suddenly drops to low charge when the battery is almost dead. To prevent this from occurring, every thirty charging cycles, you should discharge lithium ion batteries until the phone gives a low battery warning, then fully recharge it. (DO NOT fully discharge a lithium-ion battery! Lithium-ion batteries’ life is shortened every time you fully discharge them. Instead, charge them when the battery repairs meter shows one bar left.) This battery reconditioning ensures that the battery meter on your lithium ion mobilephone stays accurate. The virtual memory effect however does not affect the battery capacity as in the nickel based batteries.
All kind of the Batteries Should Be Kept Cool at All Times. Batteries last longest if they are used near room temperature. Avoid leaving your phone in a hot car or in direct sunlight, and don’t carry your phone in your pocket, where your body heat will raise its temperature, instead get yourself a mobile phone holster. Also make sure to check the repair battery while it’s charging, see if it feels hot. If it seems excessively hot, your charger may be malfunctioning. Remember, that nothing wears on a battery like extended exposure to high temperatures.
At last, you should Keep Your Mobile Phone Battery Clean.Make sure to clean the metal contacts on the battery and on the phone. Over time, contacts accumulate dirt. The best way to clean them is by using a cotton swab and rubbing alcohol. This will maximize the efficiency of energy transfer.
