Question

Quizplus · Accepted Answer

The duration of time that a battery can deliver its rated amperage is dependent on many factors including temperature, age, and the condition of the battery. However, as a general rule, a battery with a cold cranking rating of 380 amperes can only deliver that amount of current for a very short period of time. At 0 degrees F, the battery can deliver 380 amperes for approximately 30 seconds before its voltage drops too low to start an engine.
