2, Li-ion battery features: Lithium battery charging and mobile phone battery charging are completely different; lithium batteries have no memory; you can  use the Li battery at any time to charge; do not overcharge and over discharge;
3, When the light changes, you should take out the Li batteries as soon as possible, do not overcharge, especially for the first time to charge.
4, It would not be good to let the Li battery be in a non-use condition for a long time.
