Introduction What is the voltage of an 18650 lithium battery that needs to be charged? The rated voltage of a single cell of an 18650 lithium battery is generally: 3.6V or 3.7V. The charging voltage is generally: 4.20V (.

At what voltage should the 18650 lithium battery be charged?

18650 lithium battery

The rated voltage of a single cell is generally: 3.6V or 3.7V

The charging voltage is generally : 4.20 V (lithium cobalt oxide is 4.2 V to 4.3 V)

The minimum discharge termination voltage is generally: 2.75 V. Voltage below this voltage can easily lead to a significant reduction in battery capacity or even its disposal.

Maximum charging termination voltage: 4.20V
