# Battery Charger calculator

Battery Charger Calculator is used to calculate the maximum charge time of batteries, based on the entered information.

 Battery Capacity(mAh): Charge Rate Current(mA):

Maximum Time To Full Charge (MTFC)

 MTFC(10% Efficiency Loss): Hours MTFC(20% Efficiency Loss): Hours MTFC (30% Efficiency Loss): Hours MTFC(40% Efficiency Loss): Hours MTFC(No Efficiency Loss): Hours

#### Formula used:

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

Where,
MTFC - Maximum Time To Full Charge,
BC - Battery Capacity,
CRC - Charge Rate Current

The calculator finds the maximum battery charge time for for given values. Maximum time to full charge (≤10%) efficiency loss is virtually impossible and usually accepted standard for efficiency loss is 20%. The efficiency loss 30% and 40% are better than 10%. If efficiency loss is above 40% than we should try to find the reason by changing the charger or replacing the battery.
