Battery Load Tester
A tool used to test a battery's capacity to deliver current under load.
A battery load tester checks a car battery's health by simulating real-world electrical demand. It determines the cold cranking amps (CCA) and detects weak or failing batteries. Modern testers use electronic load simulation instead of resistive elements for safer operation. The results help prevent unexpected breakdowns and ensure reliable engine starting. Technicians should always test the battery before diagnosing alternator or starter faults. Load testing is a quick yet essential maintenance procedure for all vehicles.
