The Ermenrich Zing AL40 Battery Tester is designed to analyze the condition of the car battery as well as its performance and the main parameters. The device has a built-in screen and connects to the battery with two crocodile clips. You can operate the device and set the test parameters with simple controls.

The basic battery test detects the voltage, CCA cold cranking amps, internal resistance, and SOH and SOC values. Based on the readings, the tester will evaluate the overall battery health status: good, OK, fault. You can also use the Ermenrich Zing AL40 to test the charging system or the starting system of your vehicle.

The device does not require any external power supply, it is charged directly via the car battery that it is connected to.

Key features:

• Battery test: voltage, internal resistance, cold cranking amps (CCA), SOH (battery health) and SOC (charge level)
• The calculation of the overall battery health status that is based on the measurements
• Car starting system testing and charging system testing
• Charging via the battery under test
