Battery Test

Display SOH (State of Health), SOC (State of Charge), Voltage, Current, Rating, and the readable analysis results on the 2.4-inch color LCD screen.

State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions.

State of charge (SoC) is the level of charge of an electric battery relative to its capacity, SoC is normally used when discussing the current state of a battery in use

Cranking Test

The cranking test helps you analyse the starting motor including cranking voltage and the cranking time to check the starting motor works properly or not.

Loaded Voltage means the voltage measured when turning on on-board electrical appliances, such as headlights.

Unloaded Voltage means the voltage measured when turning off all the on-board electrical appliances.

Charging Test

Test different parts of the charging system, including the alternator, rectifier, rectifier diode, and so on for a reliable charging volt value.
