Discharge terminal output is not controlled by the switch on the panel, only discharge terminal is closed when the battery voltage is lower than 9.0 V output. Panel switch control on the screen and the USB socket output, when the switch and battery voltage is 9.1 V or less will display in a second on a second frequency blinking remind you should charge in time, when the battery voltage is 9.0 V or less screen out and USB socket closed output, the purpose is to protect lithium batteries from excessive discharge, this is the process of control panel on the microprocessor into dormancy, you need to manually close the switch, turn on the switch when the battery voltage is 9.1 V or higher to awaken the microprocessor, display screen to display the battery voltage value, USB is 5 V output. Although this product is the output short circuit protection function, but should not be frequently in everyday use short circuit +, - the power output.

Related to environmental protection:

Proper circulation of lithium battery charge and discharge times in about 500 ~ 800 times, to the life end of lithium battery needs to be done in accordance with the laws of the local corresponding recovery and processing.

The correct maintenance way of using lithium-ion battery:

Battery is a consumable, 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 the 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.

First, the correct way of using lithium-ion batteries

Although lithium batteries, widely used in automobile, electric cars, mobile phones, tablet, notebook, and so on are useful to the equipment, in the near future, maybe have more equipment to use it, but for now, equipment, such as cell phones and tablet, is still the nearest lithium battery power supply equipment. Therefore, it is necessary to make special instructions to cell phone lithium battery.

1, Charging

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 its almost no memory effect. So 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 these 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. In addition, another aspect cannot be ignored is the lithium battery is also not suitable for discharge, over discharge to the lithium battery is bad also. This leads to the following questions.

2, When should start to charge during normal use

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 batteries, 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.

3, Important tips for the proper use of lithium-ion battery cell phone

Boil down to, I on the problem of lithium battery cell phones in use is the most important tip:

1), according to the standard time and procedure charging, even so will three times before;

2), when there is a hint when battery power is too low, should try to start charging in a timely manner;

3), the activation of the lithium battery does not need special method, in the normal use of mobile phone lithium batteries will naturally activation. If you are determined to use of "three times before 12 hours long charging activation" approach, in fact there will be no effect. Therefore, all the pursuit of 12 hours long uses the lithium battery cell phone charging and automatic shutdown, are wrong. If you've made according to the error, please correct in time, maybe it is not too late. Of course, in the mobile phone and charger itself 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, also can make some concessions. Such as found that mobile phone must be charge before you sleep at night, also can start charging before going to bed. The crux of the problem is that, should know what is the right thing to do, and do not deliberately according to error.

Second, the battery maintenance

Actually, the battery without too much consideration on the use of attention, in other words is also not too helpful. How many times a cell can use, difference between individual differences in more from the battery itself, instead of using the method. In addition to the quality of battery, the service life of the battery itself is limited. Once the battery off the production line, its life started to pass. Whether or not you use it, the service life of lithium-ion batteries is only in two to three years. Battery capacity decline in one of the important reasons is caused by the oxidation of internal resistance increases, the cell resistance can reach a certain point, although a full battery at this moment, but the battery can't release already stored power. Many friends think first use lithium battery should be charged more than 16 hours, so that we can fully activate cells, actually do not according to, this is just the popular nimh or nickel cadmium battery charging method, is not suitable for lithium ion batteries. Because of this with a core of lithium polymer batteries, in theory, no memory effect, even if have, also is completely negligible. So just rushing around 3 hours is ok, if charging status has been completed, and the power converter is temporarily do not need to use, you can unplug the power and don't have to wait so long.

Mistake 1: PSP buy requires repeated three times in order to activate the battery charging and discharging. Unless you buy the PSP is the inventory of products more than one year, otherwise there is no need to do this, because now the batteries have been activated in the factory, the batteries when encapsulated into a PSP batteries after an equivalent to activate test again, so you get its hands on the battery, already had been activated, only three times of charging and discharging process cost anymore to increase the wastage of the battery.

Mistake 2: for the first-time charge must be sufficient enough for 12 hours. For the those without early control circuit of nimh battery equipment is applicable, but for now has a smart charging and discharging control module of the PSP is a joke, when the PSP batteries, the charging current can be automatically cut off, and when the system is shown as "external power supply. Even if you continue to 120 hours, filling state also won't have any change, in general, is completely filled with 3 hours, the rest of the "charging" is just wasting your time. Is the time to get a new machine instead should put power rechargeable light.

Mistake 3: cells need once a month completely charged. For nimh battery memory effect is very strong, this is must work, but for lithium-ion batteries, the cycle is too frequent, lithium battery, in theory, is to eliminate the memory effect, even if there were, also has been greatly weakened the negligible degree, if you use the battery is very frequent, then you should discharge the battery to the low (about 10 ~ 15%) recharging, but if the discharge to even open machine (0 ~ 1%), belong to the lithium battery has great damage depth of discharge, usually once every 2 months to do this operation. If you rarely use the battery, as long as once every 3 months for this operation.

Mistake 4: keep working while, or keep using external power after full charging will damage the mainframe and the battery. This is one of the most ridiculous arguments. So-called cavity electronics, time filling the theoretical arguments on the level of mechanism, such as how much you can learn in the actual reaction? Battery industry academic view of the first is not unified. Theory still have differences, how to guide consumers to use the actual? Battery consumption is divided into normal loss and damage loss, the power converter using and the degree of loss of charge while using the real cause, completely within the normal wear and tear, the battery that is to say, no matter how theoretical maintenance measures system, battery is aging, it's like how the magic of cosmetics and maintenance also cannot stop the beauty become old woman, most are just slow, but on the surface of the plaster of utility can exactly how many truly, this is by no means theory can explain the actual use experience is correct - respect and understanding of the scientific concept. Maybe someone says, the only way to avoid the aging of battery is not to use it, so a lot of people will choose to take down the battery), but it would make PSP portability lost its significance, and secondly even the battery is in storage, and it will burn-in as time goes by. Battery is actually a half consumable product.
