Panasonic camera battery charging

At present, all new cameras in Panasonic market use lithium batteries. The first charge of lithium battery is subject to the discoloration of charger indicator light, and it can be charged at will, without time limit. With the continuous improvement of lithium battery manufacturing technology in recent years, lithium batteries on the market no longer need to be "activated" and can be charged at will. In addition, the life of lithium battery is related to the number of charging cycles, but not directly related to the number of charging cycles. Simply put, for example, a lithium battery uses only half of the electricity on the first day, and then it is full. If it is still the same the next day, that is, it is charged half and twice in total, which can only be counted as one charging cycle, not two. Therefore, it may take many times to complete a cycle. Every time a charging cycle is completed, the power will be reduced a little. However, the reduction is very small. After many cycles, high-quality batteries will still retain 80% of the original power, and many lithium battery products will still be used as usual after two or three years. That's the reason. Of course, the life of lithium batteries will eventually be replaced. The life of a lithium battery is generally 300 ~ 500 charging cycles. Assuming that the power provided by a complete discharge is Q, if the power drop after each charging cycle is not considered, the lithium battery can provide or supplement 300Q-500Q power in its life. From this, we know that if you charge with 1/2 every time, you can charge 600- 1000 times;

If you charge with 1/3 every time, you can charge 900 ~ 1500 times. By analogy, if the fees are charged randomly, the number of times is uncertain.

In short, no matter how to charge, the total charge of 300 q ~ 500 q is unchanged. Therefore, we can also understand that the life of a lithium battery is related to the total charging capacity of the battery and has nothing to do with the charging times. There is little difference between deep discharge and deep charge and shallow discharge and shallow charge on the life of lithium batteries.

In fact, shallow discharge and shallow charging are more beneficial to lithium batteries. Only when the power module of the product is calibrated as a lithium battery, deep discharge and deep charging are needed. Therefore, the products powered by lithium batteries don't have to stick to the process, everything is convenient first, and they can be charged at any time without worrying about affecting their service life.
