Answer:
Neither A nor B
Explanation:
The charge rate of a battery is the rate at which charge is added to the battery in a given time unit. The unit of charge rate is Coulombs/second or amps
The time to charge a battery, is given by the battery charging formula which is given as follows;
Battery charging time, t = Battery Ah(Ampere hour)/(Charging current, A)
T = Ah/A
Where;
T = Time (Hours)
Ah = The rating of the battery in Ampere Hour
A = The Current applied given in Amperes
The charging current should 10% of the Ah battery rating, such that a 120 Ah battery requires about 12 Amperes charging current
However, due to losses in the system, the current can be set at 13A
the time for charging will then be t = 120/13 = 9.23 hours
