• The 18650/26650 HD-8992A battery charger has an automatic current control that protects the cells against overcharging and short circuits.
• The charger is fully automatic.
• Possibility to charge one or two or even four cells at the same time.
• It carries out a three-stage charging process for Li-ion cells to keep the cell in good condition by charging the appropriate current at each stage and completing the charging process at the right time.
• The individual stages of the TC / CC / CV process are:
• TC phase: cells discharged below 2.9V are "woken up" with a lower current.
• CC phase: after reaching 2.9V, the cell is charged with constant current and voltage of 0.25A.
• CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until the cell reaches the appropriate voltage. Upon reaching it, the charging process is complete - the battery is fully charged.
