How many amps is a car battery?

Voltage is not the same as amperage Even though most car batteries are only 6 or 12 volts, a 12-volt battery can produce as much as 600 amps. Amperage can be thought of as the volume of electricity that’s generated, but the voltage can be thought of as the “pressure” of the electricity.

How many amps will drain a car battery?

“Typically, the normal amount of parasitic draw is between 50 and 85 milliamps in newer cars and less than 50 milliamps for older cars.” A parasitic draw above this threshold is considered excessive. Over time, excessive drain can stress your battery, drawing it down quicker and shortening its life.
