charge factor

The charge factor is a characteristic value for batteries that establishes the relationship between the charging time, the nominal capacity and the charging current. It indicates how long the charging time is for a battery with a certain C coefficient

, which is the characteristic value for the charging capacity, at a corresponding charging current. The charge factor is a dimensionless value and depends on the battery technology used and represents

theefficiency of

a battery during charging: How much charge current must be used to charge the battery in order to be able to extract a certain amount of energy. Mathematically, the charge time (h) is calculated by multiplying the charge factor by the nominal capacity (mAh), divided by the charge current (mA). Depending on the battery type, the charge factors are between 1.2 and 1.5. Assuming a charge factor of 1.2 and a nominal capacity of 1,500 mAh, this means that the charging time takes twelve hours with a charge current of 150 mA. The charge factor decreases at higher charge currents at >C/1.
