How to calculate battery charge time

2017-07-07




View battery capacity and input current marked by the charger:

1. When the charging current is greater than 20% of the battery capacity:

Charging time (hours) = battery capacity (mAH) × 1.1 ÷ charging current (mA)

2. When the charging current is greater than 15% of the battery capacity and less than or equal to 20%:

Charging time (hours) = battery capacity (mAH) × 1.2 ÷ charging current (mA)

3. When the charging current is greater than 10% of the battery capacity and less than or equal to 15%:

Charging time (hours) = battery capacity (mAH) × 1.3 ÷ charging current (mA)

4. When the charging current is greater than 5% and less than or equal to 10% of the battery capacity:

Charging time (hours) = battery capacity (mAH) × 1.5 ÷ charging current (mA)

5. When the charging current is less than or equal to 5% of the battery capacity:

Charging time (hours) = battery capacity (mAH) × 1.6 ÷ charging current (mA)
