# Battery Charger calculator

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

## 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.
