Multi-Function Digital Battery Tester TopDiag BT500 8-30V 20-2000CCA Battery Tester For Car/Trucks/Motorcycle Battery Discharge Load Tester Battery Impedance Tester with Printer

The TopDiag BT500 is a professional-grade, multi-functional battery analyzer designed to test 12V and 24V lead-acid batteries. It supports a wide cold cranking amps (CCA) range of 20–2000 CCA, making it compatible with various vehicles including cars, trucks, and motorcycles.

Core Testing Capabilities
Battery Health & Impedance: Quickly assesses internal resistance, voltage, State of Health (SOH), and State of Charge (SOC).
Load & Discharge Testing: Records real-time voltage fluctuations during engine startup and under load to determine how the battery performs under stress.
Leakage Detection (Amps): Monitors real-time leakage current (15mA to 5A) to identify parasitic drains that could cause battery depletion.
System Testing: Includes cranking tests to evaluate starter motor performance and charging tests to verify alternator output and ripple voltage.
Relay Testing: Can test various relay sizes for proper continuity and contact switching when used with a compatible relay box.
