Four ways to charge lithium batteries correctly

The correct way to charge lithium batteries: 1. The safe operating voltage for charging lithium-ion is 2.8~4.2v, and the lithium-ion battery that is lower or higher than this voltage plan will become very unstable and even pose a problem. To ensure that the battery is on a safe schedule, a special charger is required. These chargers will actively adjust the charging method according to the current situation of the battery. 2. Activation Before starting charging, the lithium battery charger will supply a small current to the battery, and as the battery voltage changes, it will gradually increase the current until the set value. This process can be seen as an activation or binding charge. 3. The constant current variable pressure charging charger charges the battery with a stable current. As the voltage of the lithium battery increases, the charger increases the charging voltage and speeds up the charging speed. 4. Variable current and constant voltage charging When the lithium battery reaches 4.2v voltage, the battery can only be charged about 70% (not fully charged). At this time, the charger continuously charges the battery with a stable voltage and a gradually decreasing current, and when it detects that the battery voltage continues to increase when it is less than 0.1A, the battery is intermittently charged. So this is the correct way to use lithium batteries. Have you learned it? Normally, the correct use and maintenance of lithium batteries are necessary to keep the battery life forever young.
