How long does it take to fully charge a 200Ah battery?
5 hours, assuming that you have a 12 V 200 Ah car battery and a charging rate is 0.2C. To find it:
-
Calculate the runtime to full capacity using t = 1/C:
t = 1/0.2 = 5 hours or 300 minutes.

What is the capacity of a battery?
The capacity of the battery tells us what the total amount of electrical energy generated by electrochemical reactions in the battery is. We usually express it in watt-hours or amp-hours. For example, a 50Ah battery can deliver a current of 1 amp for 50 hours or 5 amps for 10 hours.

What is the C rating of a battery?
The C rating determines the rate at which the battery discharges. The higher the discharge rate (i.e., higher C ratings), the lower the total capacity of the battery. For example, if you have a 60Ah battery rated at 1C, this means that it is capable of delivering 60 A of current continuously in 1 hour.
