Question: 1 / 400

During a parasitic current drain test, what is typically considered an acceptable current draw?

50 mA or below

100 mA or below

150 mA or below

An acceptable current draw during a parasitic current drain test is generally considered to be 50 mA or below. This low current draw suggests that there are minimal additional drains on the vehicle's power system when it is turned off, which is crucial to prevent battery depletion over time.

While some may argue for higher thresholds like 100 mA or more, the industry standard typically favors the lower limit to ensure the vehicle's battery remains healthy and lasts as long as expected. Testing for parasitic draws is vital in diagnosing electrical issues that may lead to a battery failure, so adhering to a strict limit helps maintain vehicle reliability.

Options that propose higher acceptable limits may overlook the significance of maintaining the vehicle's energy efficiency, leading to potential long-term problems if the draw remains consistently high.
