1, the purchase of new lithium battery because of have a little electricity, therefore, users get the battery can be used directly, the remaining battery run out of charge, after such a normal use 2~3 times can fully activate the activity of lithium battery. It’s a special reminder: don’t trust the salesperson or the rumor on the network that the new lithium battery will be activated for up to 12 hours for the first time.
2, lithium batteries do not exist memory effect, can be used with charge, but should pay attention to, lithium batteries can not excessive discharge, excessive discharge will cause very large capacity loss. When the machine reminds the battery to be low, it is time to start charging.
3, in daily use, the newly charged lithium battery should be used for half a minute, the live performance is stable before use, otherwise it will affect the performance of the battery.
4, do not use the instrument, be sure to remove the battery, stored in a dry and cool place.
5, pay attention to the use of lithium battery environment: lithium battery charging temperature is 0 ~ 45 degrees, the lithium battery discharge temperature is -20, ~60 degrees centigrade.
6, do not battery and metal objects mixed, so as to avoid metal objects touching the battery positive and negative, resulting in short-circuit, damage to the battery, and even dangerous.
7, do not knock, acupuncture, trample, modification, sun batteries, do not put the battery in the microwave, high pressure and so on.
8. Use regular matched lithium battery charger to charge the battery. Do not use inferior or other type of battery charger to charge the lithium battery.
1, lithium battery factory, the manufacturer for activation treatment and pre charging, so the battery has power over, buy a new battery is a lithium ion battery, then 3~5 charge is called a period of adjustment, should charge more than 14 hours, to ensure the full activation of lithium ion activity. Lithium ion battery has no memory effect, but it has a strong “Sui”, and should be fully activated, in order to ensure the future use of the best performance. The lithium battery has been fully activated before leaving the factory, so it is not necessary to use the method of charging for a long time to activate the activity of lithium ion.
2, some automated smart fast charger, when the indicator lights change, in fact only means that full of 90%. The charger will change automatically and recharge the battery with slow charge. Do not immediately cut off the charger power, it is best to give the battery a period of time to fill the battery, the battery is full after use, otherwise it will shorten the use of time.
3, before charging, lithium batteries do not need to discharge, can not discharge, the current production of lithium battery charger is not discharge function, if can adjust the charging speed, suggest that you try to charge to charge the slow charge, fast charge reduction; whether the slow charge is fast charging time not more than 24 hours. Otherwise, the battery is likely to burn out an electrical core because of the enormous electrical flow generated over a long period of power supply.
1. Have you marked the exact capacity?. Batteries with no specific capacity (such as 1000mAh or 1000 MA) are likely to be using inferior batteries or recycling batteries. Many cheap batteries on the market are made of recycled batteries. Although the price is cheap, but the life is short and the quality is unstable, careless use may damage the cell phone.
2 、 is there a guaranteed standby time?. Standby time, that is, the time after the battery is loaded into the cell phone to the next charge. General market sales of batteries are unable to guarantee the customer standby time, this is because the battery quality is not stable, a lot of cheap batteries because of the use of poor quality batteries, so the standby time is short.
3 、 is the safety protection circuit board installed?. Without the protection circuit board, the lithium battery will have the danger of deformation, leakage and explosion. In a vicious cut, the search for lower priced protective circuits, or simply omitted the device, makes the market full of explosive lithium batteries. Consumers can not tell from the appearance of whether there is a protective circuit board, so it is best to choose reputable businesses to buy.
Lithium ion battery can only charge and discharge 500 times?
I believe the vast majority of consumers have heard, lithium battery life is 500 times, 500 times more than the number of charge and discharge, the battery will “die”, a lot of friends in order to prolong the battery life, only charge every time when the battery is completely depleted, so battery life really is prolonged effect? The answer was No. The life of a lithium battery is “500 times”, not the number of charges, but a cycle of charge and discharge.
A charging cycle means that all the power in the battery is completely empty and then empty enough. This is not equivalent to recharging the battery. For example, a lithium battery on the first day only half of the electricity, then it is full of electricity. If the second day is the same, that is, with half of the charge, a total of two charging down, this can only be counted as a charging cycle, not two. As a result, it usually takes several cycles to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases. However, the power reduction is very small, high quality battery charge and multiple cycles, will still retain the original capacity of 80%, a lot of lithium battery powered products in over two or three years, was still in use. Of course, the final is still a lithium battery life needs to change.
The so-called 500 times, refers to manufacturers in a constant discharge depth (such as 80%) to achieve about 625 times the number of charging, reached 500 charging cycles.
(80%*625=500) (neglecting the capacity reduction of lithium batteries)
Because of the influence of the actual life, especially the charge discharge depth is not constant, so the “500 charging cycles” can only serve as reference battery life.

Disadvantages of lithium batteries
1, lithium batteries are poor security, there is the risk of explosion.
2, the lithium battery of cobalt lithium material can not discharge with large current, and the security is poor.
3, lithium batteries are required to protect the line, to prevent the battery has been overcharge, over discharge.
4, high production requirements, high cost.
Lithium batteries are usually divided into two major categories:
Lithium metal batteries: lithium metal batteries are generally used manganese dioxide as the cathode material, lithium metal or its alloy metal as negative electrode material, the use of nonaqueous electrolyte solution of the battery.
Lithium ion batteries: lithium ion batteries are usually made of lithium alloy, metal oxide as anode material, graphite as negative electrode material, and nonaqueous electrolyte battery.
Although the lithium metal cell has a high energy density, it can theoretically reach 3860 watts / kg. However, due to its nature is not stable enough, and can not be charged, it can not be used as a power battery repeatedly. Lithium ion batteries are developed as major power batteries because of their repeated charging capacity. But because of its coordination with different elements, the composition of the cathode material in all aspects of performance is very different, leading to the industry’s cathode material route disputes increased.
Lithium metal battery:
Lithium metal batteries are usually batteries using manganese dioxide as cathode material, lithium metal or its alloy metal as negative electrode material, and nonaqueous electrolyte solution.
Discharge reaction: Li+MnO2=LiMnO2
Lithium ion battery：
Lithium ion batteries are usually made of lithium alloy, metal oxide as anode material, graphite as negative electrode material, and nonaqueous electrolyte battery.
The reaction on the charging anode is
LiCoO2==Li (1-x) CoO2+XLi++Xe- (Electronic)
The reaction on the charging negative electrode is
Rechargeable battery total response: LiCoO2+6C=Li (1-x) CoO2+LixC6
Lithium battery is a battery made of lithium or lithium alloy as negative material and using nonaqueous electrolyte solution. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis. In 1970s, M. S. Whittingham proposed and began to study lithium ion batteries. Because of the chemical properties of lithium metal is very lively, making lithium metal processing, preservation and use of environmental requirements are very high. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium battery has become the mainstream now.
