First of all, too high and too low power states have an adverse effect on the life of lithium batteries, and the number of charge and discharge cycles is of secondary importance. In fact, the number of rechargeable recharges marked on most electrical appliances or batteries is detected based on 80% discharge. The test stated that for some laptop lithium batteries, the battery voltage often exceeds the standard voltage by 0.1 volts, that is, rises from 4.1 volts to 4.2 volts, then the battery life will be halved, and if it is increased by 0.1 volts, the life will be reduced to the original 3 One part; the long-term low or no power state will make the internal resistance of the battery to the movement of electrons become greater and greater, thus causing the battery capacity to become smaller. NASA has set the battery power consumption on its Hubble Space Telescope at 10% of the total capacity to ensure that the battery can be repeatedly charged and discharged 100,000 times without needing to be updated. Secondly, temperature also has a greater impact on the life of lithium batteries (mobile phones and other small electronic devices can ignore this point). The environment below freezing point may cause the lithium battery to burn out when the electronic product is turned on, and the overheated environment will reduce the battery capacity. Therefore, if the notebook is used for a long time without removing the battery from an external power source, the battery will be exposed to the high heat discharged from the notebook for a long time. More importantly, the battery will be in a state of 100% power for a long time and will soon be scrapped. Lithium battery production customization From the above, we can summarize the following points to ensure the capacity and life of lithium batteries: At present, most electronic products use lithium batteries. Since their introduction in 1990, lithium batteries have been obtained due to their excellent performance. With rapid development and widespread use in society, lithium battery processors have also developed on a large scale. Do not charge the lithium battery to 100% full, let alone run out of power. Where circumstances permit, try to keep the battery power near the half-full state, and the smaller the charging and discharging range, the better; the factory design of the general ChevyVolt electric vehicle is to force the battery power to be maintained at 20% to 80%, and The built-in battery of Apple laptops may also use this method (including some other laptops and electronic products) to increase the number of charge and discharge cycles of the battery. Do not use lithium batteries (especially laptop lithium batteries) for long periods of time when the device uses an external power source. Even if your laptop has good heat dissipation, 100% of the long-term power is equal to the murder of lithium batteries. 1. Be sure not to let the battery run out regardless of whether it is a laptop or a mobile phone; 2. If you are going to travel, let the battery overflow, but please remember to charge the electrical appliances at any time when conditions permit. For the sake of battery life, do not Wait until the battery is dry. 3. If you have used an external power supply to power your laptop for a long time, or the battery power has exceeded 80%, immediately remove the battery of your laptop and charge it to about 80% without overflowing the battery; adjust the power supply of the operating system Option, adjust the battery level alarm to more than 20%. Normally, the battery level should not be less than 20%. When it drops to 20%, it will be charged in the past; Statement: Some pictures and content of articles published on this site are from the Internet, if there is any infringement Please contact to delete the previous article: What are the differences between 18650 lithium battery and AA battery?
