Lithium batteries can generally be charged and discharged 300-500 times. It is best to partially discharge the lithium battery, rather than completely, and to avoid frequent full discharge as much as possible. once the battery is off the production line, the clock starts to move. Whether you use it or not, the life of a lithium battery is only in the first few years. The decrease in battery capacity is due to the increase in internal resistance due to oxidation (this is the main reason for the decrease in battery capacity). Finally, the resistance of the electrolytic cell will reach a certain point. Although the battery is fully charged at this time, the battery cannot release the stored power,
1. Higher weight-to-energy ratio and volume-to-energy ratio;
2. High voltage. The voltage of a single lithium battery is 3.6V, which is equal to the series voltage of 3 Ni-Cd or Ni-MH rechargeable batteries.
3. The self-discharge can be stored for a long time, which is the most outstanding 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 the lithium battery before charging;
5, long life. Under normal operating conditions, the number of charge / discharge cycles of the lithium battery is much greater than 500 times;
6, can be quickly charged. Lithium batteries can usually be charged with 0.5 to 1 times the capacity, which shortens the charging time to 1 to 2 hours
7, 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.
