Usage
Lithium battery has no memory effect and can be recharged at any time and can be used after being fully charged. However, it is not allowed to overcharge and over-discharge. Based on the characteristics of lithium battery, we sum up the maintenance skills of lithium battery as the following two points:
1. Do not let the lithium battery charge less than 10% (it is recommended to start charging below 20%).
2. When the charge of lithium battery is 1%, it can be called “deep discharge”, and “deep discharge” must be avoided. Because the “deep discharge” directly affects the service life of lithium batteries, it directly leads to the failure of charging.
