1, you can't overcharge, you can't charge when fully charged, and recharging will affect the life of lithium batteries and even explode! Even lithium batteries are protected by charging circuits. It's better to charge it to 80%, not to fill it. Fully charged will also affect battery life!

2, can't overdischarge, charge before there is no electricity! There is about 20% left to recharge!

3, charging time depends, generally only one hour, if less than 80% for a period of time!

4, 3 months or so to do a full discharge of Wally, that is, shut down, fully charged 100%, which is conducive to the maintenance of lithium batteries. Don't do this! Personally, I am lazy. If I remember, I will do it. If I don't remember, forget it. A battery doesn't have to be so serious!

5. To sum up, we can draw the slogan of the inventor of lithium battery: charge with use, charge with use! It means that even if the battery is still 30%-60%, or even 70%, it can be charged conveniently without damaging the battery. The life of lithium battery is about three years, even if it is useless for three years, it is brand new, and its performance will be greatly reduced in the third year. Lithium battery has started its life cycle since it went offline. ...

I hope it helps you.
