Easy Charging Time and Charging Current Formula for Batteries. ( with Example of 120Ah Battery). How to Calculate the time for battery Charging? Easy Charging Time Formula for Batteries. ( with Example of 120Ah Battery). Here is the formula of Charging Time of a Lead acid battery. Charging Time of battery= Battery Ah / Charging Current T = Ah / A Example, Suppose for 120 Ah battery, First of all, we will calculate charging current for 120 Ah battery. As we know thatcharging current should be 10% of the Ah rating of battery. so charging current for120Ah Battery = 120 x(10/100) = 12 Amperes. but due to losses, we can take 12-14Amperes for charging purpose. suppose we took 13 Ampfor charging purpose, then charging time for 120Ah battery = 120 / 13= 9.23 Hrs. but this was an ideal case... practically, this is noted that 40% of losses ( in case of battery charging) then 120 x (40 / 100) = 48 .....(120Ah x 40% of losses) therefore, 120 + 48 = 168 Ah ( 120 Ah + Losses) Now Charging Time of battery = Ah/Charging Current 168 / 13 = 12.92 or 13 Hrs ( in real case) Therefore, an120Ahbattery would take13 Hrsfor completely charging ( with 13A charging current).
