The 18650 lithium battery is a cylindrical lithium battery with a diameter of 18 mm, a height of 65.0 mm and a rated voltage of 3.7V. In order to meet the needs of more devices, the 18650 lithium battery pack comes into being. It is assembled in series and parallel with the 18650 battery to achieve higher voltage and longer discharge time. 18650 lithium battery terpolymer as a positive rechargeable battery than lithium cobalt acid battery has a higher safety factor, but the working voltage is too low, and used in mobile phone (mobile phone cut-off voltage is generally up and down), there will be an obvious sense of insufficient volume. At present, the former is widely used in the sales market.
Precautions for battery use:
First, charge first to avoid overcharging the battery
For the first charge, choose daytime charging. It is easy to overcharge during night charging and damage the battery. And it's easy to control the charging time during the day, so watch the time when you're charging.
Second, charging time
It is best to choose the daytime charger, try not to charge the 18650 lithium battery overnight, pay attention to the time of the charger, so that there is time to deal with the danger.
Third, avoid overcharging
The time of the charger should be controlled well, preferably not more than 8 hours. Overcharging will shorten the life of the 18650 lithium battery and may also lead to excessive negative voltage.
