In a VAT battery load test, the current draw should be approximately half the CCA rating.

• A. True
• B. False
• C. Not stated
• D. Not applicable

Answer: (A)

The main idea is using a controlled, substantial draw to stress the battery and see how it handles a real starting-like load. The Cold Cranking Amps rating tells you the maximum current a battery can deliver at cold temperature while maintaining a minimum voltage. In a VAT battery load test, applying a load around half of that CCA creates a meaningful stress test: it’s strong enough to reveal weaknesses from aging or high internal resistance, yet not so high that it risks immediate damage. If the battery can sustain the voltage under this half-CCA load and recover after the load is removed, it’s generally considered healthy. If the voltage sags badly or doesn’t recover, that indicates the battery is weak or failing.
