A battery charger is a device used to put energy into a secondary cell.

Charge rate is often denoted as C or C-rate.

Battery Charger Formula:

MTFC (No Efficiency Loss) = ((BC / CRC) * 10)/10

MTFC (40% Efficiency Loss) = ((BC / CRC) * 14)/10

MTFC (30% Efficiency Loss) = ((BC / CRC) * 13)/10

MTFC (20% Efficiency Loss) = ((BC / CRC) * 12)/10

MTFC (10% Efficiency Loss) = ((BC / CRC) * 11) / 10

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