18650 lithium battery correct operation instruction

Source: 2020 - 04 - 14 18:56 hits: 18650 lithium batteries right instructions when using lithium battery should be noted that the placement of the battery is in after a period of time after enter a dormant state, capacity is lower than normal at this time, use time is shortened. Lithium battery is easy to be activated, however, as long as three to five times the normal charge and discharge cycle can be activated, and normal capacity. Due to the characteristics of lithium battery itself, it has almost no memory effect. Therefore, the new lithium battery in the process of activation in the user's phone doesn't require special methods and equipment. This not only is correct in theory, but also in my own practice, charging 'natural activation method is the best from the start. For li-ion batteries' activate 'problem, there are a lot of argument is: charging time must be more than 12 hours, repeated three times to activate the battery. This' in the first three time charge 12 hours' is the obvious continuity of nickel battery, such as nickel cadmium and nickel metal hydride. So this is a kind of misinformation. Lithium battery charge and discharge characteristics are very different from nickel battery, I can tell you very clearly, all serious and formal technical data I reviewed stress, overcharge lithium battery discharge excessive can cause great damage, especially liquid lithium ion battery. So, had better be in accordance with the standard time and standard charging methods, especially don't charging more than 12 hours long. In general, mentioned in this manual way of charging for the standard charging ways. At the same time, the charging takes a long time for a long time, generally charge at night. China power grid, for example, in many places at night voltage is higher, volatile. As has been said, the lithium ion battery is very fragile, and they to elasticity is much less than the nickel battery charge and discharge change, this will bring the additional risk. In addition, another aspect is that nots allow to ignore, lithium battery is not suitable for discharge, discharge of the lithium battery is very bad. A, normal should start charging when using this can often be seen on the BBS, because the number of charge and discharge is limited, so the battery should be recharging after use. But I found a form of lithium ion battery charge and discharge cycle experiment. Cycle life data is as follows: the cycle life ( 10%DOD) : > 1000 circulation cycle life ( 100% dod) : > 200 times the DOD is the abbreviation of the depth of discharge. As can be seen from the table, the depth of the charge and discharge times, 10% DOD cycle of more than 100% DOD long service life. Of course, if the conversion to the actual charge relative to the total capacity: 200 * 1000 * 200 = = 100100%, 10% after discharge was still is better, but in front of the net friend of idea to do some correction: under normal circumstances, you should have a reservation, according to the principle of battery recharging after using soc, but if your batteries in your expected to 2 days can't insist on two hours, you should timely charge, of course, if you are willing to once again carried when BieLun the charger to the office. Second, you need to charge to cope with the expected inconvenience or conditions are not allowed to charge, even if the battery has a lot of power, you also just charge in advance, because you didn't really lose '1' charge cycle life, namely the '0'. X, usually the x will be small. After the battery recharging principle is not to go to extremes. As for the charge for a long time, there is a popular theory is' try to run out of battery, it is best to use the automatic shutdown. 'this is just to avoid the memory effect. Unfortunately, it is also used in lithium batteries. Cells due to excessive discharge, the voltage is too low, can't normal charge and start. Three, the right way to use lithium-ion batteries to sum up, I'm in a lithium battery charge and discharge problem is the most important are as follows: 1. According to standard time and procedure charging, even three times before; 2. When the power is too low, should charge as soon as possible; 3, the activation of lithium-ion batteries do not need special method, in normal use lithium batteries will be natural activation. If you insist on using popular 'three times before 12 hours charging activation method, it is, in fact, it won't work. Therefore, all the pursuit of 12 to 16 hours long charging and using automatic shutdown of lithium batteries, are wrong.
