Notes for the first charge of lithium battery

The lithium battery charging for the first time brings many questions. As for these questions, we need to clear the following common senses.

One, full of: lithium the battery used for the first time there is no "active" problem, the reason is that: Lithium battery and Ni-Mh battery charging and discharging characteristics have very big difference, the deeper reason lies in, overcharge lithium batteries, especially on the density of its liquid lithium ion batteries cause great harm, therefore, charge should be according to the standard time and standard method, super long charge don't.

The correct way is: in the lithium battery stop immediately after separating the lithium battery and charger. Lithium battery in a (temporary) will automatically stop after filling, and there is no "continue" for a long time a trickle charge, this is lithium battery with the different areas of Ni-Mh batteries. Charger indicator after, if you don't take off immediately, because the battery self-discharge and lithium battery protection IC there is still a small current through the, can make the lithium battery voltage can thus to charging voltage value after recharge (since the charger not removed), after another round of "charging, voltage drop, recharging", make lithium-ion batteries are in charge and discharge cycle of countless times, eventually damage lithium-ion batteries, lithium battery life.

Second, the new lithium battery after it is general a certain power, can be used immediately, rather than have to charge first, then use, from the point of theory and practice, lithium battery charge for the first time was to "use again after filling" or the effect of the reoccupy after "imitation" exactly the same. There is a limit, manufacture date reached more than half of the best charge first, because the battery is too low at this time.

Three boot, shutdown charging and charging method (insert is actually filled with charger form) of the choice of don't have to deliberately, because affect the performance of the battery is the same, some lithium battery charging design in standby mode, but this kind of situation is relatively small.

Four, in terms of consumer electronics, with lithium battery charging time is usually 2 ~ 4 hours, the new lithium battery charging time will grow some for the first time, because there is no capacity loss, the result is also full of electricity can, on more filling is useless, it have already said the reason, if don't want to say anything, and side effects.

Lithium battery charging time for the first time tends to be converted to the concept of "activation". Some of the lithium-ion battery specification was first used in lithium batteries have full charge and full discharge for three apparent activation. The real purpose is different from Ni-Mh batteries.  Ni-Mh batteries tend to remove the memory effect. It means to eliminate the passivation, namely the lithium battery will produce some lithium crystallization during the transfer process for 3 ~ 6 months, which affects the activity. Eliminate passivation process can be done in the lithium battery charge for the first time, and it can also be done in normal working conditions.
