Correct use of 18650 lithium battery

In the use of 18650 lithium batteries, it should be noted that the battery is placed in a sleep state, at which time the capacity is below the normal value, the usage time is also shortened. However, the lithium battery is easy to activate, and the battery can be activated as long as it passes through 3-5 normal charge and discharge cycles, and normal capacity is restored. På grunn av egenskapene til selve litiumbatteriet, fastslår det at det nesten ikke er noen minneeffekt.

Therefore, the new lithium battery in the user's phone is in the process of activation, there is no special method and device. Not only theory is theory, from my own practice, from the beginning, the standard method is used to charge this "natural activation" mode is the best. For the "activation" problem of lithium batteries, many statements are: charging time must be more than 12 hours, repeated three times to activate the battery.

This "first three-three charging 12 hours more" said that it is obvious to continuing from nickel batteries such as nickel-cadmium and nickel hydrogen. So this kind of saying, it can be said that it is misfinalized. Lade- og utladingsegenskapene til litiumbatterier og nikkelbatterier kan være veldig forskjellige, og du kan fortelle deg det veldig tydelig.

Alt seriøst formelt teknisk materiale jeg har gjennomgått understreker at de vil overlade og overutlade for litiumbatterier, spesielt flytende litium. The ion battery causes huge damage. Lading lades derfor fortrinnsvis etter standardtid og standardmetode, spesielt for mer enn 12 timers lang lading.

Typically, the charging method described in the instruction manual is the standard charging method. At the same time, long-term charging takes a long time, often needs to be carried out at night, while in my country's power grid, the voltage in many parts is relatively high, and there is a large fluctuation. As mentioned earlier, the lithium battery is very delicate, it is much better than the ability of nickel electricity to resist and discharging, so this also brings additional dangers.

I tillegg er et annet aspekt ved ikke ignorert at litiumbatterier heller ikke er egnet for overutlading, og overutlading er også svært ugunstig for litiumbatterier. 1. When should I start the charging forum in normal use, this statement can often be seen, because the number of charge and discharge is limited, so the battery should be charged as light as light as possible.

But I found an experimental table for 2, lithium-ion battery charges, and the data about the cycle life is listed below: Circulation Life (10% DOD):> 1000 cycle life (100% DOD):> 200 times in DOD It is an English abbreviation for discharge depth. As can be seen from the table, the number of times the number of charge and the discharge depth, the cycle life of 10% DOD is much longer than 100% DOD. Of course, if it is equivalent to the relative total capacity of the actual charging: 10% * 1000 = 100, 100% * 200 = 200, the latter complete charge and discharge is still better, but the previous netizen's saying should be amended: in normal In the case, you should reserve the principle of charging according to the battery remaining battery, but if your battery is not possible to insist on two hours in the second day, you should start charging in time, of course, if you are willing Carrying up the charger to the office is also followed.

When you need to charge to cope with it is expected that it is inconvenient or conditionally not allowed to charge, even when there is a lot of power, then you only charge in advance, because you don't really lose "1" times charging cycle life, that is, " 0.X "times, and often this X will be small. The principle of battery remaining electricity is not to go to the extreme.

One way to circulate as long is the same, "Try to use the battery's electricity, it is best to use automatic shutdown." This practice is actually just the practice of nickel battery, the purpose is to avoid memory effect, unfortunately, it is also currently circulating on lithium batteries. Since the battery results in excessive discharge, the voltage is too low, so that normal charging and power-on conditions are not available.

3, attributing the correct approach to the lithium battery, my most important tips for the charging and discharging of lithium batteries in use are: 1, according to the standard time and program charging, even the top three times; 2, when When the electricity is too low, charging should be started in time; 3, the activation of lithium batteries does not require a special method, and the lithium battery will naturally be activated during normal use. If you insist on the "first three-time 12-hour long charging activation" method, it will not have effects. Therefore, all pursuits of 12 ~ 16 hours of ultra-long charging and use lithium batteries to automatic shutdown are erroneous.

If you used to do it according to the wrong statement, please correct it in time, maybe it is not too late. Note: If the original charger itself protects and controls the quality of the control circuit, the protection of lithium batteries is considerably. Therefore, the understanding of the charging rules is the focus, and in some cases it can make some concessions.

For example, if you think the battery will be charged before you go to bed, you can also start charging before going to bed. The key to the problem is that you should know what the correct approach is, and don't deliberately do it according to the wrong statement.
