Battery Charging Time Calculator

Battery capacity (mAh)  
Charging current (mA)  
Maximum charging time (10% efficiency loss)= (hours)
Maximum charging time (20% efficiency loss)= (hours)
Maximum charging time (30% efficiency loss)= (hours)
Maximum charging time (40% efficiency loss)= (hours)
Maximum charging time (no efficiency loss)= (hours)

Formula:

MTFC (10% efficiency loss) = ((BC / CRC) * 11) / 10

MTFC (20% efficiency loss) = ((BC / CRC) * 12)/10

MTFC (30% efficiency loss) = ((BC / CRC) * 13)/10

MTFC (40% efficiency loss) = ((BC / CRC) * 14)/10

MTFC (no efficiency loss) = ((BC / CRC) * 10)/10

Here

MTFC - Maximum charging time

BC - Battery capacity

CRC - Charging current
