Lithium batteries can generally be charged and discharged 300-500 times. It is best to discharge the lithium battery partially rather than completely, and try to avoid frequent full discharge. Once the battery is off the production line, the clock starts to move. Regardless of whether you use it or not, the service life of lithium batteries is only in the first few years. The decrease in battery capacity is due to the increase in internal resistance caused by oxidation (this is the main reason for the decrease in battery capacity). Finally, the resistance of the electrolyzer will reach a certain point, although the battery is fully charged at this time, but the battery cannot release the stored power.

What are the characteristics of lithium batteries? The following editor will introduce to you:

1. It has a higher weight-to-energy ratio and volume-to-energy ratio;

2. The voltage is high, the voltage of a single lithium battery is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries;

3. Small self-discharge can be stored for a long time, which is the most prominent advantage of the battery;

4. No memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so there is no need to discharge lithium batteries before charging;

5. Long life. Under normal working conditions, the number of charge/discharge cycles of lithium batteries is far greater than 500;

6. It can be charged quickly. Lithium batteries can usually be charged with a current of 0.5 to 1 times the capacity, shortening the charging time to 1 to 2 hours;

7. It can be used in parallel at will;

8. Since the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., it has no pollution to the environment and is the most advanced green battery in the contemporary era;

9. High cost. Compared with other rechargeable batteries, lithium batteries are more expensive.
