Frequently asked questions about lithium batteries

Frequently asked questions about lithium batteries. Why do you charge a new battery? The important purpose of the first few recharges of a new battery is to activate the battery. The lithium battery enters the dormant state after a period of time, and the capacity at this time is lower than the normal value, and the use time is also shortened. However, lithium batteries are easy to activate, they can be activated after three to five normal charge and discharge cycles, and the capacity is normal. (2) Does it take 12 hours to charge the first few times? Due to the characteristics of the lithium battery, it has almost no memory effect. Therefore, the user's new lithium battery is not a special method and equipment during the activation process. Regarding the activation of lithium batteries, there are many sayings: the charging time must be more than 12 hours, and the battery can be activated by repeating three times. The first three charging for more than 12 hours is an obvious continuation of nickel batteries, such as nickel cadmium and nickel metal hydride. So this is a misinformation. (3) Long charging time will damage lithium batteries? Official technical documents emphasize that charging will cause serious damage to lithium batteries, especially liquid lithium batteries. Therefore, it is best to charge according to the standard time and standard charging method, especially not to have an ultra-long charge of more than 12 hours. When the battery is fully charged, the lithium battery or charger will automatically stop charging, which means that if your lithium battery is fully charged, the charger will be empty. No one can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change, and the quality is foolproof, so your battery will be in danger for a long time in the future. This is another reason why we oppose charging for a long time. In addition, on some machines, if the charger is not removed after charging for a period of time, the system will not only stop charging, but also start a charge-discharge cycle. Manufacturers may have their own goals, but this is clearly not conducive to battery life. At the same time, it takes a long time to charge for a long time, usually at night. Take my country's power grid as an example. In many places, the voltage is high at night and fluctuates greatly. But lithium batteries are very fragile, and compared with nickel batteries, they are much less resilient to fluctuations in charge and discharge, which adds to the danger.
