Lithium battery instructions and the proper usage of lithium battery

The lithium battery instructions

The battery is a kind of consumption goods, its life is certain, charge and discharge times usually is 300-500), so the right method of use is the secret of battery "longevity". Different types of different charging battery, nickel metal hydride prone to heat and high temperature in an electric charge in the problem, such as heat out in time, easy to cause the loss of battery sex or irreversible damage even explode. In general according to the specification requirements of the battery with the charger or original charger to charge batteries can meet the requirements, avoid long time continuous charging and use is not in conformity with the requirements of the charger to charge no protection function (especially the low-grade charger), so as not to cause damage or danger, it should be right to give qualified or original charger to charge, after reaching full time is removed. usually lithium battery has a relatively complete protection function (with a protective plate), other requirements for the battery without too much, but in order to prevent the protection plate as the overcharge protection function failure caused by security problems, also not recommended for long time of charging, the battery charge after taken out, the other charge must be used when the original or attached to the battery charger, and follow the instructions to operate and use, otherwise you may damage the battery or even dangerous; Lithium battery overheat explosion fire risk of a much higher than other types of batteries, APPLE, DELL has the similar case recently; In addition, the rechargeable battery or charger attached don't have inflammable and explosive items, such as newspapers, magazines, etc.

The battery before use to check whether meet the requirements of the load, in can't meet the requirements of the load or high current (more than 1 c) use can make the battery damaged or shorten the life.

Due to long-term storage will accelerate the battery self-discharge and passivation of active material, environment temperature and humidity is 10 ° C ~ 30 ℃ 65 + / - 20% is more appropriate, at the same time to reduce the long-term storage battery (like years) caused by self-discharge and passivation the negative effects of active material and the battery every three months to do a charge and discharge cycle, to restore its original performance.

That should be paid attention to in using lithium battery, battery placed after a period of time to enter a dormant state, capacity is lower than normal at this time, use time is shortened. But the lithium battery is easy to activate, if after 3-5 times the normal charge and discharge cycle can activate cells, back to normal capacity. Due to the characteristics of lithium battery itself, determines it has almost no memory effect. New lithium-ion batteries in the user's phone in the process of activation, is don't need special method and the device. Is so in theory, not only from my own practice, from the start with a standard method to charge this way of "natural activation" is the best. For the "activation" of lithium-ion batteries, many say: charging time must be more than 12 hours, if you do this three times, in order to activate the battery. This "the first three time charge to charge more than 12 hours", apparently from nickel battery, such as nickel cadmium and nickel metal hydride) continue down. So that, the outset misinformation, so to speak. Lithium-ion and nickel batteries charging and discharging characteristics have very big difference, and can be very clear tell you, I have looked at all serious formal technical data will emphasize overcharge and over discharge of lithium batteries, especially in the liquid lithium ion batteries caused great damage. And charging in accordance with the best charging standard time and standard methods, especially don't charging for more than 12 hours long. Usually, the introduction of charging method, on the phone's manual standard charging method is suitable for the mobile phone.

In addition, the lithium battery cell phone or the charger will automatically stop after the battery, there is no nickel electric charger of the so-called "trickle charging for 10 hours. That is to say, if your lithium battery, after full on the charger is Bai Chong. And none of us there is no guarantee that the battery charge and discharge protection circuit will never change and quality according to the features of foolproof, so your battery will be on the brink of danger for a long time. This is another reason we object to a longer charge. Charging in addition on the phone for some, after more than a certain amount of time, if you don't go to remove the charger, the system does not stop charging, will also begin to discharge - charging cycles. Perhaps this vendor has its purpose, but apparently for life of battery and mobile phone/charger is unfavorable. At the same time, the charging takes a long time long, often need to be done in the night, and to power grid in China, many places are relatively high voltage in the night, and volatile. Have already said, in front of the lithium battery is very delicate, it is better than nickel electric resistance to fluctuation in charging and discharging ability worse, so it brings the risk of additional.

On the BBS, can often see this statement, because the number of charge and discharge is limited, so should be mobile phone battery electric light recharging as much as possible. But find a lithium ion battery charge and discharge cycle experiment table, data of cycle life are listed as follows:

Cycle lifetime (10% DOD): > 1000 times

Cycle lifetime (100% DOD): > 200 times

The DOD is the abbreviation of the depth of discharge. From the table, but the depth of the number of charging and discharging, 10% DOD cycle life than 100% DOD much longer., of course, if the conversion to the actual charge relative to the total capacity: * 1000 * 200 = 200 = 100100%, 10% of the latter to fully charge and discharge is still relatively better. Under normal circumstances, you should have a reservation, according to the principle of battery remaining power run out to refill charging, but if the battery in expected to 2 days can't insist on the whole during the day, should be timely start charging, of course, if willing to carry the charger to the office when Bielun again. And need to charge for the upcoming is expected to lead to the communication of the most important events in the busy, even when there are a lot more than battery, so you can just charge in advance, because you don't have a "1" real loss time charge cycle life, namely "0. X", and often the x will be small. The principle of battery remaining power run out to refill is not want you to extremes. As widespread and long charging a saying that is "as far as possible put the cell phone battery power run out, had better use automatic shutdown". The practice of this kind of practice is just nickel battery, purpose is to avoid the memory effect, unfortunately it also in lithium battery of circulating on today. Once someone because the cell phone battery low warning, without a charge to continue using has been used examples of automatic shutdown. The result from this example phone no response in the later charging and boot, had to send to the maintenance of the service. This is because the battery voltage is too low, caused by the excessive discharge that do not have normal charging and boot conditions.

The activation of the lithium battery does not need special method. In the normal use of mobile phone lithium batteries will naturally activate. If you are determined to use approach of "charge for 12 hours at the first three times to activate the battery", in fact there will be no effect. Therefore, all the pursuit of 12 hours long charging hour and using the lithium battery of cell phone until it automatic shutdown is wrong. If you've do so, please correct in time, maybe it is not too late. If the mobile phone and charger is under the condition of good quality, protection and control circuit for lithium battery protection still has quite a guarantee. So the understanding of charging rules is the key, in some cases, it also can make some concessions. For example, if you find that mobile phone must be charged before you sleep at night, you also can start charging before going to bed.
