Lithium batteries are generally capable of charging and discharging 300-500 times. It is best to partially discharge the lithium battery instead of completely discharging it, and try to avoid frequent full discharges. Once the battery is off the production line, the clock begins 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 an increase in internal resistance due to oxidation (this is the main cause of battery capacity degradation). Finally, the cell resistance will reach a certain point, although the battery is fully charged, the battery cannot release the stored charge.
What are the characteristics of lithium batteries? The following small series to introduce to you:
1. It has a higher weight-to-energy ratio and volume-to-energy ratio.
2. The voltage is high, the single-cell lithium battery voltage is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries.
3. Self-discharge can be stored for a long time, this is the most outstanding superiority of the battery.
4. No memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium batteries do not need to be discharged before charging.
5. Long life. Under normal working 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 a current of 0.5 to 1 times, which shortens the charging time to 1-2 hours.
7. Can be used in parallel.
8. Because the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., no pollution to the environment, is the most advanced green battery in the modern era.
9. High cost. Lithium batteries are more expensive than other rechargeable batteries.
