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 equipment, the 18650 lithium battery pack came into being, according to the 18650 battery series and parallel assembly, to achieve higher voltage and longer discharge time. 18650 lithium battery ternary material as a positive rechargeable battery than lithium cobalt acid battery has a higher safety factor, but the working voltage is too low, and with the mobile phone (the cut-off voltage on the mobile phone is generally up and down), there will be a significant feeling of insufficient volume. At present, the former is widely used in the sales market.
Battery use precautions:
First, charge first to avoid overcharging the battery
When charging for the first time, choose daytime charging. It is easy to overcharge during night charging and damage the battery. And it is easy to control the charging time when charging during the day, and pay attention to the time when charging.
Second, charging time
It is best to choose the charger during the day, try not to charge the 18650 lithium battery for one night, 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.
