Battery Tester
A device that measures a vehicle battery's voltage, cold cranking amps, and internal resistance.
Battery testers evaluate battery health to determine its ability to start the engine. They simulate load conditions and analyze charge state. Weak batteries cause hard starts and unreliable electronics. Modern testers display results instantly, aiding preventive maintenance. Regular testing before seasonal changes helps avoid sudden failure. Keeping terminals clean and voltage within manufacturer range ensures consistent performance and longevity.
