The calculation method of charging time for emergency charger:


The battery capacity looks at the annotation on the outside of the battery, and the charging current looks at the input current annotated on the charger.


1. The charging current is less than 5% of the capacity of the battery.

Charging time (H) = (mAH) * 1.6 battery capacity, charging current (mA)


2. The charging current is more than 5% of the capacity of the battery, less than 10%:

Charging time (H) = (mAH) * 1.5 battery capacity, charging current (mA)


3. The charging current is more than 10% of the capacity of the battery, less than 15%:

Charging time (H) = battery capacity (mAH) * 1.3 (mA / charging current


4. The charging current is more than 15% of the capacity of the battery, less than 20%:

Charging time (H) = (mAH) * 1.2 battery capacity, charging current (mA)


5, the charging current is more than 20% of the capacity of the battery.

Charging time (H) = (mAH) * 1.1 battery capacity, charging current (mA)
