Regarding the charging method of new batteries, the top three most widely distributed by the government mainly charge more than 12 hours to activate the battery. But is this kind of statement accurate?
One: This kind of statement is from the nickel battery, but the charge and discharge characteristics of the lithium battery and the nickel battery are very different. For the lithium battery, over discharge and over charge will cause significant damage to the battery, so it is the best Charge according to standard time and standard method, keeping in mind not to charge more than 12 hours.
Two: The lithium battery will automatically stop charging after it is fully charged, but it will continue to be placed on the charger, and it will show a discharge-charge cycle, the characteristics of the battery's charge and discharge protection circuit can be changed, and the battery is at risk. .
Lithium battery charger charging method
How to charge the lithium battery in the abnormal use, there are many opinions, some say "to use active shutdown, there is no electricity left to recharge", but some show "use and charge" to deal with this result , I do not stop the behavior in the first theory, but found that there is no need to do so, why?
One: The life of a lithium battery is usually 300 to 500 charging cycles. Assuming that the power supply for a complete discharge is 1Q, regardless of the future reduction of power in each charging cycle, the lithium battery can supply 300Q to 500Q of power. If you use 1/2 to charge each time, you can charge 600-1000 times; if you use 1/3 to charge points, you can charge 900-1500 times; if you randomly charge, the number of times is uncertain. In short, it can be made up that the power into 300Q-500Q is constant. Therefore, the life of the lithium battery is related to the total charge of the battery, but it is related to the number of charging. Big impact.
Two: In fact, shallow discharge and shallow charge are more beneficial to lithium batteries. Only when the power module of the product is calibrated for lithium batteries, there is a need for deep discharge and deep charge. Therefore, in the ordinary use process, you can not only stick to the use of photoelectric recharge, you can use it to recharge, with convenience first.
Lithium battery charging considerations
One: Avoid too high temperature when charging
If the temperature during charging is higher than the specified operating temperature (35 ℃), the power of the lithium battery will continue to be reduced, that is, the power supply time will be extended when the battery is fully charged, which will damage the battery quality and reduce the battery life.
Two: Avoid too low temperature when charging
If the battery is at a low temperature (4 ° C below) during charging, the battery capacity will continue to decrease, and even the battery will not be charged, but the situation is different from the low temperature situation, and it is not permanently destroyed. The battery power will also be restored to its previous condition.
Three: often used
Frequent use will keep the electrons in the lithium battery active all the time, which is beneficial to the extension of its life. If you do not use it often, remember to implement a charging cycle for the lithium battery every month, that is, deep charge once.
