1. Higher weight energy ratio and volume 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 three nickel cadmium or nickel hydrogen rechargeable batteries.

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

4. There is no memory effect. Lithium battery does not have the so-called memory effect of nickel cadmium battery, so lithium battery does not need to discharge before charging.

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

6. It can be charged quickly. Generally, the lithium battery can be charged with current of 0.5-1 times of capacity, so that the charging time can be shortened to 1-2 hours.

7. It can be used in parallel at will.

8. As the battery does not contain cadmium, lead, mercury and other heavy metal elements, it has no pollution to the environment and is the most advanced green battery at present.

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