First of all, lithium batteries do not have time extraordinary charge to activate, you can not do, there have been charging circuit protection, the plug will be of no avail.

Second, the activation of the lithium laptop battery (charging curve is correct) for the first time in the general use, not to place a long time, or that the frequent charge that is used for some time, a method that is full charge and discharge, after the batteries that can be That is sufficient to use only in use for a long time before the need to re-re-re-charge and discharge fully corrected.

Finally, the lithium battery life mainly in charge and discharge cycles, the cycle is an absolute concept, for example, if you used the last 30% of the electricity, is full of electricity, in the future, they use 70% of the electricity, and full of electricity, the Is just a charge cycle, rather than two, so those who like to make use of rechargeable batteries of the players together, you own it in fact accelerated the end of battery life.

Some of the sources of misunderstanding:

Every time a rechargeable battery exhausted from the age-old from the NICD batteries, nickel-cadmium batteries that have memory effect, if clinging to make electricity, ibm battery with the use of the increase in the number of electricity and has shown less and less of the state .

Later, the NIMH battery, fact, has no clear memory effect, but still need to complete the charging and discharging to maintain its normal power consumption shows that this is some of Japan to provide nickel-metal hydride charger refresh function of the principle.

Lithium batteries and there was virtually no memory effect, of course, long after the use of charge or curve will be slightly inaccurate, Apple provides a simple ical prompt you from time to time for battery charging and discharging for correction, but do not have a high frequency.

On the activation of the lithium 92p1133 factory just need to use a number in order to achieve the best condition, this is true, but the use of more than a dozen hours of the activation is not necessary (and meaningless) is now charging circuits are taken into account User-friendly, full of batteries will automatically cut off the charging circuit, so that you can not sleep at ease, this time could not plug in the power of fact, there is no difference.

Turning to charge more than a dozen hours of habit or from the ancient NICD batteries, such as the slow start filling model, the original battery charging circuit design behind the general in order to maintain the normal temperature of the battery and battery to prevent damage, Use a small charge current slow manner, and this circuit under normal circumstances do not have the power to determine precise function, so users are recommended such a charge 14-16 hours to see, the error is generally in two or three hours If the charge flow is too large, too charge of the battery will cause serious harm.

Later, nimh for now and rechargeable lithium battery of fast circuit, has been a very good power detection, you can use the pulse-fast high-current charge, and also to maintain the battery in the normal temperature range, and to close Full capacity soon, in order to prevent the charge-off, the circuit from the high current pulse is converted to a gradual narrowing of the trickle charge, so that even if the full power detect some deviation, the more close to full power due to the smaller the current, at the last moment Charge current has been close to 0, no damage to the 40Y6799, which is why lithium batteries that 80% of the pre-charge 1 hour to complete, and full of the last 20% of the electricity it 4 hours.

Green curve for the battery charge curve, we can see that power (voltage) of the stage before the very rapid rise in the latter stages of a very gentle, corresponding to the charge current is that there is orange.

A similar understanding:

"As such, it is not, the battery is full, continue flying the power cord is no harm!"

This depends on many cases, by and large say definitely no problem with ah!

The book is in fact general with the battery used in the AC plug ah.

However, there is a special case for a period of time the battery will not have lost some of its own electricity, this is not matter whether you win or come packed in the same book, but when the power falls, it is necessary to determine whether the charging circuit for under normal use The electricity, in that it is necessary to charge again, imagine if the place is full of power and time again full, although users do not use the battery, but batteries are in the non-stop for a small amount of the charge and discharge, accumulated over the fact that Battery consumption in sufficient and effective release cycle, so good design will be a good circuit protection, once the end of the charge, the circuit will automatically cut off, since even if no long-term battery power led to the re-fall will not automatically start charging, unless You switch to using the 40Y6797 mode.

Therefore, the possibility has been flying AC depends on your ability to design, Apple's book, and so have such protection, even though be it with ease.
