Why does the battery have to be used frequently to achieve the highest efficiency? If the charging time of the traditional nickel battery is too long, the liquid in the battery will crystallize, causing the charger to fail to charge. Therefore, in order to maximize its performance, it must be fully charged or discharged regularly. With lithium, you can recharge the lithium battery at your convenience, without the hassle of a nickel battery. Misunderstanding about the life of lithium batteries: Lithium batteries can only be charged 300 to 500 times, and then need to be replaced. Correctly stated: The service life of a lithium battery has nothing to do with the number of completed charging cycles, and has no direct relationship with the number of recharges. The charging cycle means that the battery's capacity goes from full to empty, and then from empty to full. This is not the same as electric charge. Its meaning is as follows. 7-1-1 As shown in the figure above, you will charge 40% first, 20% after using for a period of time, 30% after using again, and 20% after using again. In the middle part of the 20%, when there is only 10 When% of the electricity is replenished, one charging cycle is accumulated. Then the next cycle. A simple example is a lithium battery, which uses half of the power on the first day and then recharges it. If this is the case the next day, half of the fee will be charged and the price will be reduced twice. This is a cycle, not two. Therefore, it may take several recharges to complete a cycle. After each charging cycle, the charge will decrease a bit. However, the reduction is very small, and high-quality batteries can still maintain 80% of the power after multiple cycles. This is why many lithium-ion products are still in use after two or three years. Of course, the life of the lithium battery will eventually need to be replaced. Lithium battery life is generally 300 to 500 charging cycles. Assuming that the power supplied by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, lithium can supply or supplement 300q-500q of power during its service life. From here we know that if you use 1/2 charge each time, you can charge 600-1000 times. If you charge 1/3 each time, you can charge 900 to 1500 times. By the same token, if the battery is charged randomly, the number of times of charging will also change. No matter how, no matter how you charge, you can always get 300Q to 500Q of energy, which is a constant. Therefore, we can also understand that the life of a lithium battery is related to the total power of the battery, and has nothing to do with the amount of power. The impact of deep charge and shallow charge on the life of lithium batteries is the same. In fact, shallow charging is more beneficial to lithium batteries. Only when the product's power module is calibrated as a lithium battery, deep charging is required. Therefore, the use of lithium battery products does not need to be constrained by the process, all for convenience, charging at any time, do not have to worry about the impact on life. If the lithium battery is used at a working temperature higher than 35°C, the power of the battery will continue to drop, which means that the battery will not last as long as usual. If you have to charge the device at this temperature, the damage to the battery will be even greater. Even if the battery is stored in a high temperature environment, it will inevitably cause corresponding damage to the quality of the battery. Therefore, maintaining a proper operating temperature is a good way to extend the life of lithium batteries. 7-1-2 If you use a lithium battery in a low temperature environment, that is, below 4°C, you will also find that the battery life is reduced. The original lithium battery of some mobile phones cannot even be charged in a low temperature environment. But don't worry too much, this is only a temporary situation, unlike in a hot environment, once the temperature rises and the molecules in the battery heat up, they immediately return to their original power. In order to make the most of a lithium battery, you have to use it frequently to keep electrons flowing. If you don't use lithium batteries often, please remember to complete the lithium battery charging cycle once a month and do a battery calibration, that is, deep charge.
