How many coulombs in a car battery?

The amount of charge stored in a car battery is typically measured in ampere-hours (Ah). To convert ampere-hours to coulombs, you need to multiply the value in ampere-hours by 3600, which is the number of seconds in an hour.

For example, a car battery with a capacity of 50 ampere-hours would store 50 * 3600 = 180,000 coulombs of charge.

However, it's worth noting that the actual amount of charge stored in a car battery can vary depending on factors such as the battery's age, its state of charge, and the temperature at which it is operating.
